• Is the module vision development in labview 8.6. sufficient for acquiring images in real time and analysis using a webcam

  Hello

  I'm new to labview and trying to develop a system of eye tracking using labview 8.6. He has the vision development module, and I was wondering if this was not enough for the treatment and real-time image acquisition or could I need other software tools.

  Yes, to acquire images from a webcam, you need drivers imaq-dx.

• Recognition of map to play using LabVIEW and a webcam

  Hello

  For our project in my school (2nd year of electronic engineering), we are a distributor of Blackjack robot. In the help of LabVIEW and a webcam we'd like to take a picture of the card he's going to face and then compare it to a database, we did prior to that the program knows which card it is.

  So what we really want to do is

  -scan the card he'll deal with (take a photo of him)

  -compare with our database of predefined photos of all playing cards

  -Once it has good info is obtained, channeling through our program so that we can count and whatnot with this card.

  -He needs to recognize the value of the card, not the type (i.e. must know that it is a 4, not that it is a 4 diamond)

  I have not found a good solution, again, can someone help us project? Any tips are appreciated with kindness

  Kind regards

• What can the LAbview with a USB webcam?

  Hi there, I was wondering if someone can help me with my main project.

  I intend to purchase the NI Labview remote control.

  I want to be able to control the distance of Labview Panel through the web.

  Is it easy to generate NI Labview Remote Panel application on my own? I'm still in College.

  or can I buy the NI Labview Remote Panel app for $309 and use applications to control my labview through the web software.

  in this case, I counted about writing software to take the USB camera and post it on the web.

  What can I do with the usb camera?

  can I change the color? hear the sound? you guys can suggest me to do if I get to work with the web?

  Help, please...

  Thank you in advance...

  OK, back to topic.

  A classic exercise would be the detection of changes such as the detection of an object moving for security, etc.. Expand on that and save images when movement has been detected. Another step further, to subtract the background of the object in motion and present a sequence of images of just the moved object.

  Too exotic?

  That level down to a manually-initiated process to do a "what's new? It compares a before and after picture and shows you what has changed.

  I'm trying to use the webcam in acuqire photo. But it's always show me error timeout.

  No matter, I have install driver logitech or remove driver logitech.

  C920 is supported?

  I searched on it, I think that C920 might be allowed.

  Who can help me?

  Thank you

  

  Yes, thank you for your reminder.

  My solution is to increase timeout.

  

  

• Use of USB Webcam

  Hello

  I have been designing an experience for the introductory class in my Department. The idea is to control a system based on color. I had to use a webcam to do this. The problem is that I have a webcam to a 3rd party. Is it possible to use this webcam application? If this is the case, should what driver I download? Finally, how to integrate Vision Assistant with LabVIEW. I need to control the system based on the image capture. I apologize if this seems to be a confused mess. Thanks for any help you can give.

  Andrew

  Hi Andrew!

  Would you be interested to sign up for the beta program Vision?  This will include the new driver IMAQdx, which will include the USB driver update.  To register, go to ni.com/beta to register.  I think it would be a good step in you get up and running.  Please, if you have other questions!

• My integrated Webcam is recognized by MAX but not as the IMAQ device

  Hello

  I use with 2014 LabVIEW IMAQ 14 and IMAQdx14.

  I am able to use my webcame MAX both in the Vision Assistant, but when I am trying to generate vi, in the wizard, IEEE1394 Imaging is grayed out.

  When I am using triggered image acquisition and select cam0 as the name of the interface (name of my camera to the MAX), I get the error code:-1074397163 (NOR-IMAQ: the session or the interface passed is not valid.)

  In MAX, I can see and use my camera, but it appears directly in the devices and Interfaces (and not under devices NOR-IMAQ)

  I can't find out if it is compatible live show... Is this to say that my camera is not supported by IMAQ? Is there a way to check whether LabVIEW?

  Thank you

  Karol

  Hi Karol,

  Since you are able to use the camera in MAX, it is DirectShow compatible. The reason why you get this error, it is that your device is not compatible with the IMAQ driver. Instead, you should be using the driver IMAQdx and corresponding IMAQdx live. Once you use those, you should be able to control in LabVIEW. It isn't an IEEE 1394 device either, so I think that it is expected that all options for this would be grayed out. Hopefully that should get you going in the right direction, but please post again if you have problems with the generation of VI you.

  Thank you

• Improve the resolution of Image of USB camera in LabVIEW

  Hello:

  I am currently working on taking images in LabVIEW using a Logitech HD Pro Webcam C910 USB camera. I have attached the simple VI that I use. For some reason, LabVIEW is no longer able to take a picture of resolution 640 x 480 with this device. However, its capabilities are well beyond that. According to me, it can reach a resolution of image fixed of 1920 x 1080. How can I get LabVIEW to snap a picture at 1920 x 1080 with this device? I have attached a jpg of the VI.

  Thank you in advance,

  Brad

  Brad,

  IMAQdx functions will not displayed either because you have not installed IMAQdx or they are not allowed. Both come on the setup of the Acquisition of the Vision, but are separate elements that can be enabled/disabled during installation. If you use the Vision Development Module, you should have a license to activate the IMAQdx as well. Check with the License Manager AND verify that it is authorized.

  You'll really like using IMAQdx much better than IMAQ USB functions. There are many more features supported and it is fully supported in all software OR, as measurement and Automation Explorer. You can configure your camera inside MAX settings and then save and use them in LabVIEW automatically.

• Cannot create an installer containing IMAQdx in 2014 of LabVIEW

  I have a strange question in the generation of installers with a function IMAQdx in LV Application Builder 2014.

  When I was building an installer for an executable file using IMAQdx in 2013 LV, Application Builder automatically selected additional installers needed and IMAQdx drivers (Vision Acquisition) were one of them. Now I'm trying to build the project even in 2014, but in the additional installers, I see only NOR-IMAQdx DURATION 14.0. When I build the installer in 2014 LV, the size of the file is about 300MB opposed to 900MB of the installer which has been built in 2013 of LV.

  When I run the installation program from 2014 on a 'clean' Windows, install and run any application that uses IMAQdx, I do not see the cameras connected. This problem is fixed after manual installation Vision Acquisition software of DVD drivers for the device OR. After that, I can see all the cameras in the application and in MAX.

  I tried to manually add additional installers in 2014 LV, but nothing helped. It seems to me that there is no way drivers IMAQdx bundle in LV Application Builder.

  I found a post related to this and I wonder if someone can reproduce this behavior before dropping off a CAR. I have attached a simple project with a simple VI and installers of the sample in for testing. The VI allows you to select a camera (e.g. a webcam) and video image.

  Hi martin.zmrhal,

  What you see with only the Vision Acquisition Software runtimes (VAS) available in the list of installers extra is expected with the latest behavior.

  Before Vision Acquisition Software (VAS) August 2014, programs additional installation to after-sales Service, namely OR-IMAQ, e/s NOR-IMAQ and NOR-IMAQdx not only includes the runtime components but also for LabVIEW application development support. GO August 2014 and later, now only allow us the deployment of runtime components. This gives the advantage of a substantially reduced Installer size, but you can include more support development (ADE) LabVIEW applications is in the installation program.

  This change aligns Vision with LabVIEW behavior and most of the other products OR you cannot deploy generally support the complete development of a product, but rather only the runtime components. If you need to install GO with ADE on your deployment machine, you will need to distribute the complete Installer GOING on this machine in addition to LabVIEW (to make use of the SAV ADE support). To do this automatically, you will need to write a batch file to run the installer for LabVIEW, then IMAQdx.

  With respect to the second issue of not being able to see the camera, I think that what you are experiencing is that the drop of the control Session is dimmed and you cannot click on it to see a list of the cameras on the system. It is also the expected behavior for the runtimes are going TO. This does not mean that the driver is not well that discovery of cameras, and you can test this by typing the name of the camera in the Session control (for example "cam0" for the first discovery of camera on the system).

  What we are looking for with this behavior, is for vision applications deployed to abstract the end-users camera selection process. Ideally, your code must list programmatically cameras with IMAQdx list Cameras.VI and then determine what device (based on the type of bus, serial number, model number, etc.) to the target. We are working on an application note paper that clearly explain with some examples, but the idea is similar to this example of community for NI-DAQmx devices: https://decibel.ni.com/content/docs/DOC-10014.

  I'm sorry for the current lack of documentation on these features, but without a doubt, we are working to provide examples useful and other items in the knowledge base at this address. I'll post a link to the content as soon as it is available.

  In addition, Vision Acquisition Software August 2014 f1 went live yesterday: http://www.ni.com/download/ni-vision-acquisition-software-august-2014-f1/4974/en/. The patch is also available through the Update Service, and it is strongly recommended that you upgrade if you still use drivers of August 2014.

• USB webcam

  HY all. I'm beginning to realized the complexity is labview... I am new to programming in labview so I need your help... I'm trying to make a program that allows you to capture an image of my USB webcam, but I don't know very well and the driver problem is worse! I had already read this topic avicap32.dll. I preferred a project to do, I need someone to help me?

  I need UN program who can see my USB webcam with a botton that allows you to capture an image, something that learn the path to registration photo (I don't know what is called... something that I can give the path to the folder of the United Nations and stay like that)...

  Hope that's not big thing to ask and I can help me! Nice day!

  Thanks for trying to help me. So, on the http://forums.ni.com/t5/LabVIEW/2-hours-finished-the-webcam-program/m-p/906890/highlight/true#M40866... works for me, but only in Labview 8.5 or more...

• Vision: Measure light intensity of webcam

  Hi, I'm trying to measure the intensity of light of LEDs with a webcam to detect whether the light is on or off. I started with a labview example: "Light meter" and tried to change to work with a web cam as input streams. I didn't work at all... What I am doing wrong? I'll post my file and example.

  I want it to work as in the example "light meter". And then decide what range of intensity of light, the light is on or off.

  Everything I did in 'Test 7' is trying to do too much the "data entry" come from a web cam instead of a file. Help, please!

  

  I get this error... In any case I don't really want this feature. I want a return on investment. I got the vi to work.

• Camera compatible LabVIEW

  Edit: I just found a Logitech HD Pro Webcam C920.  USB webcams are compatible with labview?

  I created a VI that distinguishes the difference between 2 images.   I already bought a Foscam wireless IP camera to take the pictures, but it is not compatible at all with LabVIEW (cannot make a .icd file).

  Is there a security/webcam/camera HD (about 1Megapixel) camera that can be used in conjunction with LabVIEW? Ideally, a USB camera would work with a long extension USB cable.  I searched everywhere and can not find a device that can work wil LabVIEW and is reasonable in price (~ $ 100).

  Any help would be appreciated!

  A project I want to do is write a Labview application that would communicate to the Webcam USB and publication of the application in a secure web page, and allowing users to control Labview applications at home, work, and anywhere in the world without having installed on the PC of the Labview software. On the web, users can control the Labview front panel for zoom, annotations, etc. As a surveillance camera the USB Webcam will be detect an object moving, save images when motion was detected, an alarm to alert.

  I was wondering if anyone can help me with this.

  I have Labview Vision and I can get the USB Webcam streaming images.

  I don't know where to find information about the detection of a moving object.

  Can someone help me on this please?

  Hi krispiekream!

  I guess that your USB camera has the ability to zoom through a control programmatically? If not you should be able to control the camera using a remote facades, which require the LabVIEW runtime engine. Here's a tutorial on the remote Front Panel LV development of Applications: http://zone.ni.com/devzone/cda/tut/p/id/3277.

  With respect to the detection of a moving object, you can take two images and subtract to determine if there was movement in the frame.

  I hope this helps!

• retrieve and record continuous images in labview

  Hello

  I use the NI 1744 smart camera to capture and record continuous images of a moving object. My smart camera is detected in MAX and made the seizure of an image. But when I use the attached file of VI in labview, the smart camera is not detected, only the webcam is detected and a video can be generated using the webcam. Please help me detect the NI 1744 smart camera. I will be grateful.

  Hello

  Your smartcam is not directly accessible from your PC because it is a remote device.
