• Several cameras simultaneously on Labview

  Hello

  I'm new to Labview programming, so it would really help if you guys can help me...

  I have an Exchange virtual server and 2 GigE cameras and I have developed an inspection using Vision Builder program, that works perfectly for what I need. The thing is that I have to run two cameras at the same time - as two tasks at the same time - and I realized (with support) that it is impossible to do such a thing with Vision Builder. So, I have to do all this work on Labview now...

  At the moment I can't use the Exchange virtual server, so I'm with a RESUME, to test... I use a scA640-70fm and a Basler A631f, the two IEEE-1394 cameras. So here is my question:

  To make both cameras working at the same time, is there enough creating two simple While loops and put the Acquisition of the Vision of each cam function inside of their? Is it supposed to work this way?

  because when I am doing this and spin, I don't see on the face before Labview two cameras running at the same time! It seems odd, with cameras acquire images that the other and images sometimes disappear... looks like it does not process images at the same time.

  I'm doing something wrong? Should I take another procedure to make it work the way I need?

  Should I have problems when I perform this procedure on my cameras GigE with EVS?

  Thank you so much in advance...

  You are correct that Vision Builder AI is sequential in terms of how he runs the individual steps. Algorithms in these steps and how they execute can take advantage of multiple cores to help them run faster on machines with more than 1 kernel, so in that sense, some steps may take advantage of multiple cores, but several steps cannot run at the same time. This does not prevent several images acquired since the same trigger to be treated so. The stages of acquisition supports an immediate mode, which means that if two cameras were triggered at the same time, even if the steps in order, the pictures, they come back can come at the same time in time and you can use the step select an Image to switch the image you wish to treat. It should be benchmarking of your inspection in VBAI on the Exchange virtual server (much faster than CVS) before moving on to a parallel architecture more complicated in LabVIEW with several loops of execution simultaneously.

  One reason your previous test with several loops may not have worked, is that you may have named the image that you have created with the same name. This basically means the acquisition of two loops would be overwhelming each other images. Make sure that when you use IMAQ create, you provide a unique name for each image. Another suggestion for how to ensure hourly LabVIEW each loop on a separate processor is to do two under the screws that are configured for different delivery systems. You can set this by going to file > VI properties > run > favorite Execution System on the VI and selecting the different systems.

  Certainly, you should be able to have several running in parallel loops in LabVIEW, but before jumping to this approach, it may be worth benchmarking of the VBAI solution first because this will make it easier to make changes to the code, and it provides steps to high level who don't have to worry about things like having unique names for the images.

  The comment above about the parallelism of the loop For is useful if you want the same code to run in parallel, which you can't do because you're acquisition from different cameras. He'd also manipulation of the results of different cameras and disguishing which translates to go with what more difficult camera. That's why I recommended the VI sub running in various delivery systems as a more flexible way to ensure that you take advantage of both processors.

  Hope this helps,

• acquire a large number of images

  I am trying to get pictures from my camera to the possible largest FPS.

  Each image is an array of integers (1392 x 1040) 2D.

  For now, each cycle I am adding the image in a table of images:

  

  and this table will - of course - memory.

  Its effect can be detected in the downturn of the acquisition:

  

  ... which deviates from linear.

  What do you suggest me? Of course, I will need to save the images table and empty it,

  but there are additional tips in Labview that store more efficiently this kind of structures (tables of 2D array of integers)?

  Thank you!

  Bob, it's the kindest suggestion, thanks! The code I got with the camera Thorlabs and he is really big (and not ugly, I guess).

  The ugly portions are ones I'm introducing to customize! Since I come from VEE and I broke my face against Labview a few weeks ago, I don't know that I make a lot of mistakes :-)

  Ah, another essential piece of information - the camera is a camera of Thorlabs (you don't mention the model) and (probably) use their LabVIEW drivers.  One of the first functions Thorlabs tell you is 'table to Vision", which transformed their Image (owner) format, a table 1 d, table of pixels more intuitive LabVIEW 2D, allowing you to (if you choose) to use the IMAQ functions to process your images.  I dare say, you will find several readers of the Forum know IMAQ faced by Thorlab functions.

  So where is the attached VI?

  > But they were is your array of 2D image?  All you ´placing in a 2D table is a table 1 d.  How do you get the table 1 d of an image?

  dkfire, the image is returned by the camera as a 1 d array and then remodeled:

  See my previous comment on "Vision Board".

  > Curiosity, why you add images in your table, such as "the last shall be first"?

  Bob... well, it's just that when I contemplated the palette table for the first time, the tool "insert into array" seems to be exactly what I need... (and no, it's not a 'reversal of the table"somewhere more later... :-)

  When you try to create a 2D array by adding a 1 d array at the beginning or at the end of a 2D existing (even if it is empty) array, the much-more-natural-and-intuitive-function-to-use is 'Building the table' (Hey, he still sounds logical).  And, as a bonus, when wire you the table 1 d in there, you can Choose in a 'natural' function to build the table in 'normal' order or 'inverse '.

• Microsoft SQL 2008 Express

  I'm having a problem connecting a MSSQL 2008 Express Server configured in Mode of Windows authentication by using the LabView database connectivity toolkit. I tried the following connection strings and received the following errors:

  DRIVER = {SQL Server} SERVER =\SQLEXPRESS. UID =\; PWD =;

  the error States:

  NI_Database_API.lvlib.vi B Open connect (String) tools-> odbc.vi testException occurred in the Microsoft OLE DB provider for ODBC drivers: [Microsoft] [ODBC SQL Server driver] [SQL Server] Login failed for user '-'. in NI_Database_API.lvlib.vi B Open connect (String) tools-> test odbc.vi

  PROVIDER = SQLOLEDB.1; SERVER =\SQLEXPRESS. UID=\; PWD =;

  the error States:

  NI_Database_API.lvlib.vi B Open connect (String) tools-> odbc.vi testException occurred in the Microsoft OLE DB for SQL Server: Login failed for user '-'. in NI_Database_API.lvlib.vi B Open connect (String) tools-> test odbc.vi

  I know that this user has the right to change the database and I know that it is not a firewall issue, as I tested it with the firewall off the coast.

  Help would be appreciated!

  It seems that, because I use the Windows Authentication Mode, there is no need to use the UID and PWD in the connection string. in fact, its use causes the error.

  DRIVER = {SQL Server} SERVER =\SQLEXPRESS.

  DRIVER = {SQL Server} SERVER =. \SQLEXPRESS;

  Can be used when connecting to the SQL 2008 Express Server.

• False claims RADIUS of customer VPN Cisco ASA 5510

  Hello world

  I use the Cisco VPN client 5.0.7 and Cisco ASA 5510 (7.4 and 8.4.2) VPN RAS solution. Clients are authenticated using certificates and RADIUS AAA (ACS 3.3) and AD.

  Each time, when the client connects, ASA 2 RADIUS requests questions, correct first - which is successfully authenticated by FAC and immediately - second that always fails. I couldn't find information related to this strange behaivor. Function "Double Authentication" (more sympathetic to his name) is only accessible to Anyconnect customers who we do not. When I'm authenicated by using password group, there is only one query RADIUS.

  What is the source of such behavior?

  The negative impact is that my logs are filled with the failed authentication attempts fallacious and users are incrementig attempts failed in the AD meter.

  Hello

  It is a 'classic' error and has nothing to do with dual authentication, but rather with the fact that you do both radius and authorization of RADIUS authentication.

  If you remove this line:

  authorization-server-group RADIUS01

  you will see that it starts to work properly

  In short: when ASA no authorization of RADIUS, it sends a request to access radius with the username as a password, that's why you see the second application fails all the time.

  This is because the RADIUS authorization is intended to be used when authentication happens using certificates (only) so there is no password.

  Also note that within the RADIUS protocol, authentication and authorization are not separate things, both occur in a single step. So if the ASA makes the radius authentication, he already gets the user attributes in the authentication step and it makes no sense to also make a separate authorization stage (except in a few very rare scenario where you have 2 radius servers, one for authentication and another for permission).

• FACE RECOGNITION is not loaded at system startup

  I create my foto, add them to my windows account-made everything, who has been described in the standard manual for face recognition utility.
  But... When I turn on my laptop - no icon for the face recognition is shown... just system request password as usual. I have no idea about it, please advice sth.
  Thank you.

  Hello

  The password (keyboard input) is the backup solution when you can not log of face recognition using the webcam.

  If you use the recoganization to face for the first time that the practice is very useful.
  First of all, you will be asked to move your neck slightly to the left and to the right.
  Then, you will be asked to move your neck slightly up and down.
  After that, you can click once more to practice or click to start the capture an image.

  First adjust the position of your face so that it fits in the face in the form of framework
  (back-button will be inactive at the moment.

  Once your face has been correctly positioned, the recording will start. See the red dot for recording in the upper left.
  Start moving your neck very slightly to the left and to the right as the guide, it shows to you. Now your neck up and down. You need to repeat the movement of your neck left and right and up and down several times... Just look at the guide...

  Registration to complete, after having repeatedly moved your neck left, right, up and down. Click the button for the test of authentication.
  There are two possible outcomes:

  -If the authentication (or updated) fails, click on and register again
  -If the authentication or updated is successful, click on and create an account

  Choose your Windows user name, the full name, the destination of Login, password
  And re-enter the password fields and then click.
  Return to the management screen. The registered account name will be displayed. Clicking on it will cause the image of your face to be displayed to the left. Click close to close the software (.. and come back at the beginning of the presentation...)

  To update your profile of face recognition choose and highlite your username
  and click on update.
  To update your registration with practitioner just click Next and the guide will start.
  If you choose to ignore the recognition will start without practicing.

  Check these steps and your face recogonisation should work fine

• Authentication http post VI errors

  I am trying to query a web service to third parties non-LabVIEW LabVIEW 2014, using HTTP POST. Using another utility (restclient-ui-3.5-jar-with-dependencies.jar), I checked that URL, user name, password, and query syntax are accurate and are running on the same computer where my VI fails. I must be missing something when translating that to LV, because I get the error 401 (full authentication is required) and also 415 (unsupported media type).

  I have attached the configuration file used for the other utility, my VI and an overview of the response from the Web service for the post of the VI.  I had to make all anonymous, hide url, user, etc., so it can not really be tested as it is, unfortunately. I tried with & without additional authentication header, with & without Config SSL, etc. You can see the different options on the VI.

  Any suggestions?

  Thank you very much.

  Solved my problem with a combination of different required headers and syntax fixes.

• GNU versus LabVIEW radio

  LabVIEW seems to be the software simple and straigh - before using NI USRPs. I don't know much about LabVIEW but I know a bit about programming with GNU radio. It seems extremely flexible and attractive, at least for a programmer.

  So my question is that I'm going to face too many problems for the USRP NOR to work with GNU radio? I read here and there on the FPGA image and firmware. I would rather not touch the material at the moment, as other people will use it, probably through LabVIEW.

  Thank you.

  Hi saeedafra,

  I don't know exactly what is your question.  Using a NOR-USRP with GNU Radio should not be a problem.  Make sure that you put the right image FW and FPGA on the device, as you said.  If you want to be able to use the same FW/FPGA for LabVIEW and for GNU Radio/UHD, I would use UHD 3.4.4 and NOR-USRP 1.2.  It is not the most recent version of UHD, but it will save you from having to reflash the images to come and go between the platforms of different software.  Please let me know if this does not fully answer your question, and I'll do my best to get you the answer.

• How to program using Labview to an accelerometer

  Hello:

  I got an accelerometer which has digital I2C/SPI serial interface, so I bought a USB - I2C converter for data acquisition. I would like to know if I can use Labview to acquire data of com port and also program for the accelerometer to capture the data of the axis z. I have a box of white myDAQ NOR but SB. says that it is not an appropriate device to acquire before I2C/SPI signals. The datasheet of the accelerometer is in the accessory and the specification of the converter is this link: http://www.robot-electronics.co.uk/htm/usb_iss_tech.htm .

  I hope someone can solve the problem for me. It is best to use the software labview for me because most of my project work is based on that.

  Best regards

  The f

  Good and bad news.  You have an accelerometer that 'speaks' I2C or USB to I2C converter, so if you connect both of them, you can send 'orders' of your accelerometer easily of LabVIEW by using communication series live that's the good news.  The bad news is that it seems that you need to address your accelerometer using calls very low level, a work, I certainly don't want to face!  This crys on a 'pilot', a middle piece of equipment that does all the "hard work" to take a high level order ("Please tell me the acceleration") and he translates things your device includes (including the Setup program, records, calendar, packing and unpacking of the bits and bytes, etc.).

• labview real-time clock display

  Hey dude, im doing a project on labview that I just want to make prettier for the speaker

  is it possible to add a clock to the façade that tell time, ideally in format:

  any help welcome

  Thank you

  Pretty cool Tim.  Here is an old floating around, I got that has a neat wooden face and the code is really simple.   It is in LV10.

• How to fix the error of Labview 2016 (32-bit) on Windows 10 database.

  Hello

  I have software to read/write of labview (32-bit) database, which works fine on windows xp 2000 / 7 (64-bit). But it is not stable 10 (64-bit) Windows at all.  It pops up an error on most of the time. Please see the attached database VI. After starting my software, usually, there is no error on the face of the database of frist. but it pops up an error when opening the database section. the East-2147418113 error code. It seems that it will be more stable if I put more than a few seconds before you open the second database.

  Could someone help me understand how to solve this problem?  Enjoy.

• Protocol Bluetooth Stack in LabVIEW

  Hello

  What I'm trying to do is to use LabVIEW on a PC with an attached Bluetooth dongle to talk to an owner designed Bluetooth device to connect with Bluetooth phones. I need the program to send some commands to the patented device, disconnect, then connect and talk to another device. The patented device that I want to connect is essentially just a server waiting for a cell phone to communicate with her. Once connected, garbage are exchanged between the phone and the device, and once authenticated, the Unit completed its function.

  I've tested my Bluetooth dongle using the Simple Bluetooth Client.VI and the Simple Server.VI of Bluetooth running on two different PCs. They have been able to connect and transfer data properly.

  My question arises, however, in LabVIEW allows you to specify a channel to connect via Bluetooth. The device patented essentially being a dumb device, she wants to follow the typical Bluetooth Stack Protocol and start once paired frequency hopping. He will not be able to devote himself to a single channel and frequency with the computer of pigs.

  So I want to know is how LabVIEW treats the Protocol. The string that you specify in the VI Bluetooth actually affects the Protocol or that's just the way it communicates with the Bluetooth dongle? I have just need to know if LabVIEW supports already the Bluetooth protocol, or if there is a way around a dedicated channel. I want the computer to display and behave like a mobile devices view.

  I read through several of the NOR tutorials, examples and discussion forums, but I couldn't find answers to my question. I could be missing something simple or easy here, but I want to assure you that it is still possible to achieve before I start to develop the code.

  What I use:

  LabView Full 2012

  IOGear Bluetooth 2.1 USB Micro adapter

  I must admit that I'm not the most technically savvy person when it comes to Bluetooth stacks and protocols, so please excuse mistakes with technical information, I could have. I must, however, work colleagues who are very experienced in Bluetooth (but not in LabVIEW), worry is not on the level of technical language that you use.

  Thank you for your considerations in my problem. Do not hesitate to ask others (within limits reasonable owner) or clarification.

  Kind regards

  Bronson

  bronsonmock,

  The screws of LabVIEW Bluetooth and functions use RFCOMM, which is a connection protocol that exposes the Winsock interface. RFCOMM is a simple protocol that emulates communication series. The RFCOMM interface defines the clients and servers of Bluetooth.

  Creating client applications and server Bluetooth in LabVIEW is similar to creating applications server and client for TCP communication. A Bluetooth Server uses the Protocol for discovery of Service (SDP) to broadcast the availability of the services on the server contains and listens to incoming connections. A client creates an outgoing RFCOMM connection to a server. Once the client and server connect to each other, they exchange data until the client or the server terminates the connection or the connection is lost.

  Bluetooth of LabVIEW functions are really just a wrapper for the Windows bluetooth library functions. You can take a look and see how these protocols are processed to a lower level comprehension. I've also included this document where I shot the first two bits of information.
