Get an image from USB cam without NI VIsion Acquisition

HI
I am looking for a way to capture images from USB cam without using a paid library ImaxDx for Labview.
Have you any ideas?

Hello MaxEngee
Off hand, I suppose you could run the third party capture software in the background and have a LabVIEW scan the target directy for changes/new images and import the image as necessary.
In the mean time, if you install the NI Vision Acquisition Software, you do have a 30-day trial period so perhaps you may consider exploring the environment to see if it is right for you.

Vision Acquisition Problem

I have Problem in Vision Acquisition when I click double click on it, it doesn't appear to me "NI-IMAQdx Device" it is just appear to me "Simulated acquisition" why?
How an i solve it?
Any Help?

NI Vision Module is designed to help develop and deploy machine vision applications . Includes hundreds of functions to acquire, process images , location of features, identify objects and measure parts.
The Vision Development Module ( VDM ) presents image processing functions for LabVIEW , C / C , Visual Basic, and . NET . VDM functions are used for image processing some of them are : pattern matching, particle analysis , edge detection , threshold , histograms and optical character recognition . Furthermore, VDM includes Vision Assistant and code generation tool similar to VBAI . Vision Assistant is a useful tool to develop and test a series of image processing steps and code generation .
Vision Builder for Automated Inspection ( VBAI ) is a standalone development environment that requires no programming . VBAI includes over 100 of the most used VDM tools , including : pattern matching , OCR , and particle analysis . VBAI can run programs on remote destinations , and also has the ability to configure the remote targets .
Vision Acquisition Software ( VAS ) is a set of drivers and utilities functions to acquire, display and save images from any camera NI GigE Vision camera , or IEEE 1394 (Firewire ) and USB . VAS is included in both VDM and VBAI .
You can perform image acquisition only drivers from VAS , but for any treatment or handling or VDM VBAI you need , plus VAS . You can download the evaluation software from the following links :

Multi-Camera-Link Vision Acquisition using .avi

So I'm trying to use two Camera-Link Cameras (JAI CM-200-MCL) with the NI PCIe 1430 frame grabber in order to obtain video of a y-axis tensile testing project, and I'm relatively new to the whole LabVIEW experience. Essentially, I want to be able to capture every image of the testing process, so I can correlate the tensile testing results with specific images using the same sample clock, (e.g. data taken at 30 seconds match the image taken at 30 seconds). I'm trying to put everything together in piece and I already have a fairly stable, working tensile testing program written for LabVIEW 2009. I'm now in the process of using IMAQ (4.4) to track these images and save them as a .avi file. I've provided some sample code -- although it currently isn't working -- that's very simplistic.
Questions:
1. Is there an even simpler way?
2. Can I sync the tensile testing VI and the Vision VI by placing the Vision VI in the Tensile Testing VI inside an event structure that's triggered by the "start" button. (Boolean)
Thanks

lyncheb,
How accurately do you want your test and images to by synchronized (second, millisecond...)? If you only need to be accurate to around 1 second then software timing would work. However if you need sub milisecond accuracy you will want to use hardware triggering. The 1430 is capable of hardware triggering over a RTSI line. See page 16 (2-4) of the user manual here: http://www.ni.com/pdf/manuals/372016a.pdf
What kind of data are you logging? What hardware / software are you using to log this data?

Open cam VI in Main.exe and Vision Acquisition License

Hi,
I've an application which controls some devices...I've two questions:
1. I'm building an exe of my main VI. When I run it as exe on other PCs, it doesn't open the subVI (cam_pos_test.vi) (on my PC is everything running ok). The cam subVI is added in the always included VIs, when I build the application. Part of the main level VI looks like this (control/producer loop):
in the red circle is the subVI which opens the Ref to the cam_subVI. It looks like this:
I think: I make some error in the defining the path of the subVI (cam_pos_test.vi). Do you have some idea, what could be wrong? Why the cam_pos_test does not pop-up as it should on the other machines? :-) I've tested the cam_pos_test.vi as exe is running on other PCs.
2. I've Vision Acquisition License on my PC. Do I need Vision Acquisition License also for the PC where the executable is running (to use a cam)?
Thanks!
Angel

Hi,
I've LabVIEW 2010 Prof. + Vision Acquisition License on my PC (where I write the code). To check: is the problem in the source code or in the executable, I've used an evaluation version of LV2010 on another PC ... as a VI it runs without problems on the lab PC, but as an executable it runs but doesn't open the cam window :-( (everything else is ok)
The code of the cam.VI is attached. I've used only IMAQdx VIs to obtain an image from the cam...
Thank you for your time,
Angel

Vision acquisition not reading avi file

Hi-- I am currently running LabView 2010 (version 10.0f2) to run the Multi-Worm Tracker (http://sourceforge.net/projects/mwt/).I am currently using the Vision Acquisition Software evaluation version, though I do not have any image acquisition hardware or camera connected; I am only concerned with running AVI files. Everything seems to work perfectly except the program does not appear to "see" the file, even though I am able to select it upon opening without issue.
It appeared to me to run and track images the very first time I ran MWT, though I was not able to see the video at the time. However, it has not worked since that first time. I am curious if anyone out there has thoughts on:
1) Whether or not it is the vision acquisition software that is responsible for this problem
2) If the evaluation version only works once (seems silly as it is good for 30 days... 28 now)
3) What I might be able to do to troubleshoot this
Thanks for your help,

-Sorry no info on how you are reading avi file?
-It is just an exe. That too looks like it needs lot of other dependencies.(Or am i missing anything??)
-If you need to clarify your doubt on Vision acquisition, just use one of the inbuilt examples in labview for reading avi files and then proceed.
-No, i think evaluation version works untill evaluation time expires.
-You need to provide the code not exe to troubleshoot on more.
Thanks

Vision acquisition software, library activation

I am having a problem and I would be very grateful if you kindly help me through. I have labview 2011 installed and licensed on my pc, I also installed the ¨vision acquisition software¨ from the Divers CD. Now after a while the vision acquisition library has stopped working and ask for activation. I have bought the vision acquisition software separately and I have the activation code, but I could not find a way to activate the installed library on my pc. I would appreciate if you kindly respond at your earliest convenience.
Solved!
Go to Solution.

Hello,
try locating and running "C:\Program Files (x86)\National Instruments\Shared\License Manager\Bin\nilmUtil.exe".
(x86 on my computer!)
This is the license manager, where you can activate your license. Right click on "Vision Acquisition Software" and activate. Follow the instructions.

Do i need an updated vision acquisition software with LV 8.5

i have been using LV 7.1 with vision acquisition software installed from cd that came with IMAQ card. i installed a full developement of LV8.5 and when i installed vision acquisition software there are no VIs that show up in the "vision and motion" functions. i need to find IMAQdx functions to read my 1394 IEEE camera.
is this a version issue? what can i do to get tthe 1394 functions in LV8.5.
thanks
NI vision acquisition: version 8.2.3
Labview: version 8.5
Message Edited by arawtry on 09-23-2008 11:14 AM

Dear arawtry,
Yes, this looks like a version issue. You need NI-IMAQdx 3.1 or later, which comes with Vision Acquisition Software 8.5 or later. You can determine version requirements from the following KnowledgeBase article:
NI-IMAQ and NI-IMAQdx Compatibility with Different LabVIEW Versions
http://digital.ni.com/public.nsf/allkb/6B55FF09D1FBD3108625719600650B7C?OpenDocument
I believe downloading and installing the latest version of the Vision Acquisition Sofware should solve your problem:
Vision Acquisition Software 8.6

Saving Images Using Vision Acquisition Express

I'm trying to save an Image as a jpg using Vision Acquisition Express. My code looks like this. I am able to view the images and scroll through them afterwards, but when I add the file saving portion, I get an error that says "Error 1074395995 occured at IMAQ WriteBMPFile File not found."
How should I go about Fixing this?
Also, when i was running this before, I was getting a memory error and I couldn't figure out how to clear the memory. I was only able to fix this by scraping my previous script and starting over. I haven't gotten this error so far.

Hi,
The error you are getting indicates that the file path is invalid. I just set the file path to my desktop and I could save the files. I would double check to make sure the path you specified is valid for the computer you are running it on.
As far as the memory error, it is really hard to say what the cause is. If you aren't getting it anymore then I wouldn't be to concerned.

64-Bit Labview Vision Acquisition

I am currently in the process of upgrading from LabVIEW 7.1 to LabVIEW 2011. I have been able to get everything working with LabVIEW 2011 (32-Bit). I have installed the Vision Acquisition and all works well with LabVIEW 2011 (32-Bit). When I try to use the LabVIEW 2011 (64-Bit) I no longer have the Sub Vis that are in the Vision and Motion Pallet. I was wondering if the LabVIEW 2011 (64-bit) needs an additional download in order to allow my Vision Acquisition toolbox to work.
Thanks,
FChiragh

Go to:
START > Control Panel > Programs & Features
Then double-click on "National Instruments Software" and remove everything related to Vision and IMAQ.
Then reboot your PC. And then reinstall it.
When you reinstall it, make sure the installer indicates that the software will be installed to "C:\Program Files\..." and not "C:\Program Files(x86)\..."

Vision Acquisition Block does not open Wizard

Hello,
I'm trying to use the Vision Acquisition block but it just does not open the settings window/Wizard.
The block Vision Assitant opens normally.
However, if I open a .vi that had the Vision Acquisition configured, it compiles, but will not let me see their properties, settings, nothing. Also, if I double click on it to try to open it undoes the previous links. The LabView seems to try to load something, but in the end nothing happens. I have already reinstalled Vision Acquition and nothing. And the license is ok. In MAX, the camera that I want to access appears functioning normally.
Any suggestions?

Having the same problem. I am using the Student version of both. I can go into Vision from tools but when I place a vision acquisition block in vi nothing happens. Can not see properties etc.

Writing a Compressed AVI File in NI LabWindows/CVI with the IMAQ Vision Acquisition

I'm still facing some problems when I try to save pictures from a GigE Vision camera into a compressed avi-file in a LabWindows/CVI application on Windows7.
The task is to grab images from the camera with 30 fps to monitor a process, evaluate the grabbed pictures to find certain characteristics of the monitored process and save them in an avi-file to have the possibility to load and evaluate them once again Offline if necessary.
My questions: which compression filters can I get with the NI-Imaq Vision Acquisition and Vision Development Runtime 2012 SP1? Is a mpeg4 codec available to compress quickly and effective? Can I use a third party codec or only the ones delivered with NI-Vision?
I posted the problem two times already, but there is little response up to now. Thanks

The encoding algorithm, or codec, that's used for compression needs to present on your system. When I had done some research on this sometime back, I found that if your custom codec could align with the DirectShow architecture, then your codec would work with IMAQ AVI functions.The codecs that are available may vary from system to system, depending on what software is currently installed.

Vision Acquisition Express vi stopped working

Hi everyone,
The Vision Acquisition Express vi always worked perfectly on my pc, but suddenly, he stopped working today (I can drop it on the block diagram,but there is no pop-up or something,
I tried the following:
- restart pc (didn't help)
- try other express vi's (including other vision express vi) (worked fine)
- convert it to normal vi (empty vi as result)
- open properties with rightmouseclick (didn't help)
- open an example en doubleclick and rightmouseclick properties (didn't help)
Anyone an idea??
Best Regards,
Henk
Solved!

Hi Henk_kempen,
This is really weird. Do you know what has happened to the VI/PC before this happen?
There are some troubleshooting you can try.
1. This problem really close to DAQ assistant issue in this white paper. You might try the method in the link below to see if this solve your problem.
http://digital.ni.com/public.nsf/allkb/5CD79190713D2B558625765F007FCC99
2. Repair the software is another option. It worked in many cases.
3. I try to avoid this but reinstall the software may help in your case.

No wiring point in Vision Acquisition function.

Hello,
I have download the vision driver and want to use Vision Acquisition function under vision express to get image from my webcamera. The initialization part works well. But after I place the icon on the block panel, I can't find wiring connection points on the icon.Could someboby tell me how to deal with it?
Btw, I am using labview 2013 as well as NI Vision Acquisition Software September 2013.
This is my result.
This is the result I am looking for, how to add stop(F) and Image out below Vision Acquisition.
Thanks in advance!!
Cheers,
Dylan

The Vision Acquisition block looks unconfigured. Do you get an option to configure the express VI? It your license still active. You can go to NI License Manager to check the status.

Vision acquisition on TPC-2512

hello,
I designed code to grab video from an IP camera using IMAQdx and deployed it on a TPC-2512, the app run well but the Image Out shows black screen.
When I run the code on my laptop it works fine (the laptop and TPC are both targets in the same project) and i can see the video from the camera on the TPC using the web browser and when using IMAXdx example app and it also identified on MAX so it's not a connectivity issue.
I also tried to use vision express vision aquisition instead of IMAQdx and it worked on the laptop but not on the TPC (shown black on the image out).
I used LabVIEW 2011 to design the VI on the laptop with NI IMAQdx 3.8.1, the TPC works with LabVIEW Run-time 2011 and NI IMAQdx 3.5 so it might be the problem. The camera I use is AXIS 206 and i enabled free access without password.
I attached a picture of the block diagram.
thanks, Daniel.

Daniel,
Unfortunately vision acquisition software is not officially supported for Windows XP Embedded. However since all you want to do is display the image, a possible workaround would be to acquire images in the host VI then use network streams to send the images to the Touch Panel to display. Here is a knowledge base article that describes how to send images over network streams. I hope this helps.
