Several acquisitions of IMAQdx USB camera simultaneously

• MAX cannot find two usb cameras at the same time

  Hello

  I want to use two cameras usb (Thorlabs DCC 1545 M) in NOR-IMAQdx in Labview, but it cannot find a single camera (the one plugged earlier), and also a single camera is shown in MAX. Both cameras working in the manufacturer's software, and if I unplug the 1 unit, the 2nd will be displayed in MAX after a refresh.

  I found that one camera is supported for each USB hub in Labview, and all USB ports in this computer correspond to a same hub online. I don't know if this is causing the problem.

  In fact, I need to take the picture in both cameras at the same time, a switch programmed between the two cameras will work for me.

  Any suggestion and comment will be appreciated.

  Hello Hosni,

  According to this link, you can acquire from multiple USB cameras simultaneously.  The limitation is on the manufacturer and how they interface with the bus of DirectShow.  When you use two cameras of the same make and model, it sometimes happens that not enough information is not IMAQdx to distinguish between the two cameras.  When you switch to MAX cameras, they come as different cameras, or they appear actually virtually the same?

  Since you said switching between them might work, I found an example that does just that.  Just make sure you give a name to each camera single camera.  I hope this will be useful for you.

  In addition, there is a bit of discussion on this topic on the forum of discussion already.  Check out these related threads, or use the search box to search for more.  There is much information available!

• Camera not found, error 1074360311 occurred at IMAQdx Open Camera.vi, USB cameras labview 2013 64 (bitts)

  I use USB cameras with labview 2013, and I can acquire images in the MAX and in the Acquisition of mink (express) settings, but when I run the VI, always appear the same error as shown in the Image below.

  -J' checked the correct versions of my software, IMAQ, IMAQdx, VDM 2013 IMAQ of e/s

  -J' I also make sure I had all the updated device drivers.

  -I'm using IMAQdx LKD schema and examples, getting the same error uu

  Help, please!

  Any suggestions would be very helpful.

  

  If it works in the pop up app Express VI and inside MAX (the two 32-bit applications), then I guess it will work in 32-bit LabVIEW. We wonder why it does not work in 64-bit LabVIEW, but these are the drivers of the device and other pieces of infrastructure/DirectShow Windows.

• IMAQdx change adquiring fps with USB camera

  Hello

  Im working with Labview to process images taken with a USB camera. I would like to know how to change the terms of adquiring of the camera, in particular the frequency of frames per second (fps), video mode and resolution. I need to change these settings in real-time, while the program is running.

  Thank you.

  Hello again!

  I still have not found one camera where the pace was not changeable. Perhaps you need to change the video mode.

  I created some clips for you to play with (attached). Drag and drop the images in a chart vi copy the code (you may need to save images to disk first).

  Best regards

• IMAQdx USB Image capture

  Hello world

  I have Labview 2011 and uses a camera Basler ace acA1300-200uc, which is supported by NEITHER. I have a few simple things I need to do with this camera. First off I have to put in a trigger to my Labview code, saying that it starts when one trigger in another program Labview occurs. Then I need to open a video stream live on the screen for the duration of the test. I have in fact need to record video. In addition, I need to capture an image of the video two or three times in the first thirty seconds of the video.

  I looked through the forums and have found only a few examples of how to do to capture images from a USB camera without having to pay $4000 for the software IMAQdx arounf. I believe that my task is far too simple to justify the purchase of this software that I don't need to deal with images or videos somehow, other than the capture an image of the video stream. Anyone has any advice on how to proceed in Labview?

  I ended up buying a capture card that came with the software for the Acquisition of the Vision, which includes imaqdx. If I had taken the camera through OR I think it would have also accompanied the software and I could avoided the couple extra hundred (but it was cheaper to get the capture card to just buy the software on its own).

• 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.

• Connection of the USB camera - OR-IMAQ for USB cameras installation problems

  I tried to install the usb http://zone.ni.com/devzone/cda/epd/p/id/5030 camera application

  Unfortunately it does not work. I don't know the usb icons in my function palette. can you help me please?

  I want to only connect a camera usb with labview. How can it be difficult. any help would be appreciated.

  see you soon

  Hello

  You first need to make sure that the USB camera is DirectShow compatible.  If it is not it will not work with the software of our vision. You must use the drivers IMAQdx (which requires a license) to acquire from a USB webcam.  Once you have installed the drivers IMAQdx (Vision Acquisition Software) and drivers that come with the webcam is installed, you should be able to see it able & Automation Explorer (MAX).  Once you can see it in MAX you can use it like any other device in LabVIEW.

  Kind regards

• Size of capture USB camera

  I have the camera USB 'chat' with a resolution of 640 x 480, but IMAQdxSnap or IMAQStartAquasition.vi enter 1280 x 960 pixel of the image. How to change the size of the bucket to the native size.

  I have LV and Vision 2010

  I am using 2009, but it should work for you.

  Open Measurement & Automation Explorer (MAX) and select your USB camera under: devices and Interfaces-> NOR-IMAQdx devices.

  Select the attributes of the Acquisition.

  Select the video Mode you want (640 x 480) in the menu dropdown.

  Click Save at the top of the window.

  Now, run your application.

• How to take snapshots of two usb camera at the same time

  Hello

  I have a project where I have to take still photos of two usb camera at the same time repeatedly and save the in a particular direcltory. I am received using a camera by using "Camera Grab vi", but I can't make it work with 2 cameras, I use the flat sequence and 2 "Camerra Grab vi: with particular camera in a sequence, but each time when I run the program I get only pic of a camera, its seems a camera dominates the other.»

  Please is it possible to use the two camera simultaneously. Attached are the snapshot of my vi.

  Thank you

  Ankit G

  Looks like you are using the same reference at the same time grabbing the camera. The two camera snaps happen but the second camera clamp is written on the first so it seems alone is slam. Try to run the VI executiong highlighted arbitrary mode (select icon icons four bulb to the right of the button run on the schema). This will allow you to see the data stream. In order to get both of these Snap you'll need separate references. You can try to watch one of our examples in the example Finder OR give you some direction (LabVIEW > help > find examples > Browse tab > Input and Output material > IMAQdx > high level > Snap.vi). You can break the two cameras at the same time if you just copy this code and double of the code.
  (Note: If you change the examples, always save as copy in another location so that you do not save on the packed example)

• USB camera does not

  I have a 'VF0700 Creative LIVE! Cam Chat HD"USB camera that worked well in Mac OS X before my update to OS X El Capitan. It appears as a USB device in the 'system' report and I tried different usb ports and reset the SMC and be "zapped" the LANDAU.  No idea if this will be fixed in future update?  It's a standard UVC camera and it works with Skype and photo booth, etc. with the old OS X (I have a Mac Pro 3.1) and I can boot the old system and it works fine).

  librarian7 wrote:... it works with OSX... older...

  From your description, your device should work with 10.11.4.

  First, use Apple http://support.apple.com/kb/HT2090 to check the user-specific problems. You may simply move on to a user account that does not have the problem.

  (BTW - troubleshooting section called an "iSight" camera.  However, after that article was published, Apple has changed the name of the built-in camera on the recent "iSight" Macs "FaceTime", then "FaceTime HD."  Whatever the name of your built-in camera, the same info and troubleshooting applies.)

  To check the user-specific problems, you must test several Apple app (photo booth, FaceTime, iMovie, QuickTime Player, etc.) in more than one user account.  Do NOT use a 'Guest' for this test account.  If you have not already established a separate user, testing account, create one now.  If you need help, how is explained in http://support.apple.com/en-us/HT201754.

  A 'Standard' user account is all you need for the tests.

  If your camera will work properly with Apple in any OS X 10.11.4 applications user account, use OS X Recovery to reinstall completely your Mac OS X 10.11.4 System Recovery stored on your startup disk.  Don't bother test Skype or other 3rd party apps until you have your camera works with applications Apple.

• The Apple Magic Keyboard can operate without bluetooth when connected to an iPad with the lightning to the USB camera adapter?

  The Apple Magic Keyboard can operate without bluetooth when connected to an iPad with the lightning to the USB camera adapter?

  I love the Apple Magic Keyboard to be very light (I want it with me everywhere). I also like that I can choose the layout of the keyboard I want (Canadian multilingual), which is not available on any keyboard for any brand, with the exception of Apple iPad (and I did a ton of research). I have problems with the old model of keyboard Apple Wireless because of the Bluetooth connection: I often have trouble connecting. I want a reliable keyboard. I don't like having to plug the keyboard on the iPad, and I think that a wired keyboard can more reliable and safer than a wireless keyboard. And a wired keyboard never had battery problems.

  I read that the Apple Magic Keyboard can work wired with a Mac without bluetooth. And I read that some USB keyboards work with lightning to the USB camera adapter. There are several keyboards with a cable (Belkin or Logitech) lightning, but none with the available Canadian multilingual.

  So, if I buy a magical keyboard Apple and a Flash to the USB adapter of the camera, according to my needs, I'll be satisfied or I'm going to be disappointed?

  A better solution would be to have a male-male cable lightning between the keyboard and the iPad, but I don't find any of these products anywhere.

  Thank you.

  It will not work. And where did you read that the keyboard works wired with a Mac?

• the USB camera to array image

  LabVIEW dear Experts,

  I have a USB camera and I would like to use labview to make some simple image manipulation algorithms, problem is that I don't have Vision Development / modules Vision Assistant. I can extract a matrix of pixels of this device through labview without these modules? Just a 2d pixel values table... Thank you

  If you want to do it all in LabVIEW, then you will have to buy the software for Acquisition of Vision.  You could then acquire the image, save it in a file and then use the reading * image * File.vi on the range of graphic Formats to read the image as a cluster pixmap.  You can then use the Unflatten Pixmap.vi to produce a 2D image data table.  If you do not need to acquire in LabVIEW, then save the image as a PNG, BMP or JPG and then do the same thing.  Once you have the table image you can perform calculations as you would any other table data.

• usb cameras to sbRIO interface

  Hello

  We have a humanoid robot which has engines Dynamixel actuators for the movement of the hand and the usb camera high definition to the eyes. I want to build a control in real time of the robot to mimic the movements of the hand of a human being. For this I use sbRIO 9633 which has a processor FPGA and real-time. My first task is to get the images of the eyes in the sbRIO usb cameras do image processing and extract the skeletal details. My questions are the following

  b are there already existing drivers for usb cameras that can be installed in sbRIO to get images or streaming video?

  (b) someone wrote drivers for depth as XBOX Kinect for any target integrated measuring devices (I've found for Windows)?

  (b) if the usb port can be controlled through FPGA or is the USB interfaced directly with processor in real-time?

  (c) any acquisition images using sbRIO help to control in real time is appreciated.

  Thank you

  Libson

  Hi, Ahmed.

  The two cameras that work with the sbRIO are Basler and Axis Network cameras. The following knowledge base contains more details. This help answer your question?

• -1074360266 error to IMAQdx Open Camera.vi

  Hello

  We have problems with our LabView vision system; the VI is able to "run" with an intact arrow, but there is an error that appears:

  "Error - 1074360266 occurred to IMAQdx Open Camera.vi" with a possible reason of "NEITHER-IMAQdx: (Hex 0xBFF69036) Impossible to reach for the driver in kernel mode.

  For a little history, we had initially scheduled the VI in LV2009 (where it worked fine), but the customer upgraded to LV2010 (where it now comes up with this error), so it would be logical that it has anything to do with the problem.  In addition, we use two cameras Basler A601f via Firewire connections, which both are recognized by the Basler pylon Viewer software, so we're pretty certain that it's only a problem of LabView.

  We have tried to reinstall the drivers of Acquisition of Vision software, but it does not solve the problem, so we gradually loss.

  Any help or pointers are appreciated, and I apologize in advance if I've left out any relevant information.  Thank you.

  Ben,

  Are you able to find the camera and get him to the MAX?  Also, what version of IMAQdx you have installed?  Driver versions are MAX on the software tab.  Because all this happened after an upgrade to a new version of LabVIEW, I suggest to re - install device drivers CD, then reinstall the software of Acquisition of Vision.  I would like to know how this happens.
