LabVIEW controlled prosilica camera is not as fast as software prosilica own viewer, why?

I use "grab.vi" and "Grab and attributes Setup.vi" in "IMAQ1394 examples.llb" to test the Prosilica CV640 camera.
I find that cadence is still about 30 pictures per second, not as fast as the Prosilica visualization software, about 100 frames per second.
I set the speed shutter as 2 ms.
I followed the instructions in the website (http://www.prosilica.com/support/nationalinst.htm) to set up the camera.

I am a new user of labview. could you help me get the frame rate high?

problem solved. Thank you.

  • Prosilica GigE GC750C Camera do not acquire images using software of NOR

    We recently had a camera Prosilica GigE to GC750C. After activating the camera, Jumbo packets is recognized and acquires images with the help of allies Sample Viewer. The camera is also recognized by the NI Vision Assistand and MAX. But trying to acquire images results in the error message attached. I would be very grateful for any help.

    Best regards

    Benjamin UB says:

    Thank you much for multiple responses.

    The AVT UniCam Version 1.1.3.0 allies and Allied SampleViewer Version 1.24 buy images correctly. This is why I can't imagine that a firewall might be interfering. Also affecting the packet size to 1500 Max only has not solved the problem. Any other ideas?

    Hi Benjamin,

    If you use a software firewall, there are actually quite a few reasons that a piece of software can acquire, but the other may not. Software can set different layers to the network stack and the behavior can be very different. In my view, both software places AVT can reach are either user-mode (in which case the firewall software can easily be configured based by application to let traffic through) or as a network filter driver based on the core (which lies below the firewall, so it is not affected by the latter). If IMAQdx, two locations, it can attach to the network stack are either in kernel mode talk to the TCP/IP stack (above the firewall) or as a driver miniport directly above the hardware and below the firewall (if you have an NI GigE Vision card or one that is compatible with the Driver OR High Performance).

    New versions of the GigE Vision standard has a new feature that make the Protocol more 'user-friendly' firewalls. Our next version of IMAQdx (which I think should be on the web every day now) has support for this new feature. We tested the new AVT cameras and it is supported as well. This should be the firewall issues such less problems.

  • Portege Z30-C-12Z cam does not work with Win 10

    Hello!
    I have a problem with my Portege Z30-C-12Z. Camera in win10 does not work.
    Error code: 0xA00F4273. Have tried all the following steps: http://answers.microsoft.com/en-us/w...0-71c220c123a9 and like many more check the BIOS etc.

    According to me, I tried and everything, checked it please help!

    Try this:
    Type of storage in the search window and go to the storage system settings page. Make sure that the economy sites point to existing folders.
    I moved the files on a SD card and the camera could not find the folder of photos. Also, I've seen the suggestion to check that the folder of photos contains the security settings to allow access.

    If still no good, remove the driver of the webcam from the Control Panel, then let Windows Update to install a driver for the webcam update.

    Reinstall the camera application can also help.

  • Can PlayMemories control several cameras AS15-HDR?

    I have a pair of Sony HDR-AS15 cameras that I use to record stereoscopic images. I have so far lacked an Android/iOS device that I could use to control the cameras on WiFi, so I could not test, but I can buy one in the near future just for that purpose. I was wondering if anyone else here has tried this?

    So the question is: can you simultaneously connect and control more than one HDR-AS15 camera via the PlayMemories application?

    If not, can we at least pair / register with more than one camera, one at a time?

    Thank you!

    After starting PlayMemories app you get on the start screen where app scans for devices and you can choose from the list on which you connect.
    If you can only connect to one device. You would need 2 smartphones for control 2 cameras.

  • X 1 carbon Gen3 touch screen camera does not

    Hello

    As in the description, I have the 3rd generation X carbon 1 with a touch screen. I have problems my camera integrated into the work. I think that I remember when I got to my laptop, but I haven't used in a while. Yestrday, I googled Hangouts to try and use the camera again, but it did not work. I continued to look for his start-up. I tried to download the latest drivers (who would never complete installation because it could not find the device). I deleted my antivirus. I disabled my ad blocker on my Chrome. Rebooted my laptop several times. I did a bunch of stuff, but nothing seemed to work. I went in the program of camera integrated by default on my laptop and it shows just a camera with an X through it, it seems that my laptop is not plugged properly or something. A way to fix it? It is a tiny little problem that I can fix it with, or is it a bigger problem at hand? Or... I'm just delusional? I never had a built-in camera?

    Open settings of Lenovo from there, you can control your camera, WiFi, Bluetooth and much more ensure under camera that the security mode is not enabled, if it is then it will not be sent the images from the camera turn off so he can send photo again since that one thing security when you use not the camera to prevent hackers / intruder to misappropriation of your camera to see what you at home so they can penetrate when nobody is home to steal things.

    If that does not fix it reboot the bios then find section i/o in the bios and make sure integrated device said he [Enabled] and not [Disabled] if there disabled that also areason why it won't work.

  • Space required on target RT for LabVIEW Control design and Simulation

    Hello

    I want to run a DLL file on an RT target using LabVIEW Control design and Simulation, but I'm not sure of the required amount of RAM on the RT-target. My RT-target options are respectively cRIO 9002 and cRIO-9004 with 32 and 64 MB of RAM. Is this a sufficient amount of RAM to run the simulation? ¨¨

    Thanks in advance

    This will depend on the size of your dll, the size of the rest of the code, you can create other necessary drivers/modules, memory use when your application runs, etc.

    9002 and 9004 have not a lot of RAM on them and the minimum software installation to run a control application Design & Simulation (CD & Sim) will take around 22Mo of it (the majority of RAM available to the 9002). It would be possible to run your application on these two controllers if you keep it small but it will depend on what you want to do.

  • LabVIEW code 3 error: could not load façade.

    Hello

    I was the second time the "LabVIEW code 3 error: could not load before sign.» When you use the development of LabVIEW 2009 SP1 environment.

    It's really annoying that I waste time as I have to go back to previously saved code.

    Does anyone know where it comes from and how to avoid it?

    Thank you

    Pawel

    Pawel,

    If the façade is damaged, there is little that we can really do about it. So the best thing is to make sure that the front will never get corrupted at all.

    You can write a small VI using VI Server to check the position of the element in your VI. If there is way to positions of reposition before saving the VI.

    Another reason could be much, duplication of controls (including the faulty XControls?)...

    hope this helps,

  • Tracker camera does not

    I made this a hundred times and now it does not work

    I have a clip of camera Tracker button is pushed.

    It analyses the clip and solves it.

    However does not create the small x on the screen for me to create a target and null device.

    There's nothing here?

    You need to have the camera Tracker selected in the effect controls panel, you have not turned on hide layer controls in the view menu, you must be in the Active camera view in the Composition Panel and if all this is correct, you may need to increase the size of the markers to see. A few shots to produce very small markers. If none of these suggestions, try a different shot of follow-up. If this doesn't help, try studying upward, followed by the camera by typing in the field find help in the upper right of the AE and check on the training material.
