IMAQ USB for LV2009

Hi,
I updated Labview from 8.6 to 2009, with Vision.
After installation of ni-imaq-usb library (August 09 version), USB Acquire Image is available in Vision Assistant 8.6 but not in Vision Assistant 2009. Same issue in the Control when I code in the back panel.
Furthermore refering to 8.6 librarie when coding in 2009 make close the vi and Labview 2009 without any explanation.
Is there a version of IMAQ for USB available for Labview 2009?
Solved!

Hi,
Thanks for the Imaqdx informations, now the cameras are listed by Imaqdx Enumerates Cameras.vi, but IMAQdx Get Image.vi produce the error: " Invalid pointer". I tried with one creative webcam and one usb frame grabber. I both installed their own drivers after installing Vision Acquisition 2009, it's possible to acquire with their own softwares.
And in Vision Assistant 2009, in the Acquire tab, the first item Acquire Image is unavailable and tells me "no image acquisition device is curerntly installed in your machine." The other Acquire Image items (IEEE 394, RT ...) are available but no cameras of these types are installed or plugged. This fact goes again Imaqdx Enumerates Cameras.vi, but the result is the same: it doesn't work.!

thans for help.

You can use the USB IMAQ library along with the USB IMAQ application provided by NI. Right now i dont have those files with me in this PC. I can attach the application file and that library soon.. Mean while you can google for those things. They were made from LV 8.6 but supports upto 2009 (Am using)... you can try for 2010 also.
The best solution is the one you find it by yourself

How to set the exposure time and the gain of a connected camera with IMAQ USB

A camera was connected to my computer with USB port and we can acquire the image through IMAQ USB. Now we have to set separately the exposure time and the gain with the camera's driver software provided by the manufacturer. My question is: how to set directly the exposure time and the gain of this camera in Labview?

Hi Frank
Welcome to the forum. Have fun

Why is IMAQ USB Snap.vi constantly giving out a 32-bit image?

Hi.
I'm using some USB cameras (uEye) with Direct Show. I use the IMAQ USB camera tools (with Labview 7.1, Vision 7.1.1) as in the examples. In particular I'm working in the snap mode.
I create an U8 image (IMAQ Create) which I use as input to IMAQ USB Snap.vi and I set the camera's video mode to grayscale (Y8) using IMAQ USB PropertyPage.vi
But, I don't get an 8-bit image out of IMAQ USB Snap.vi. The image is always converted to 32-bit RGB. In principal It works like this, but it costs me valuable time to convert the image to 8-bit at some points of the program where I need the image grayscale array.
Cheers,

Labview 5.1 - 2011

Hi Elmar,
Thanks for answering.
Of course, the "not officially supported" thing is a killer argument. But the device shall work with a laptop and, as I know, the firewire cameras need an additional power supply when connected to a laptop 1394.
The camera I use is grayscale and only works properly when I write 8-bit grayscale in its settings (e.g. using IMAQ USB PropertyPage.vi).
As I said, everything I can set is set to 8-bit. The Snap.vi converts the input IMAQ image to 32-bit.
But maybe you are right and it's just that NI's USB Direct Show dll is not treated with high priority (note: I use the most recent one, although I combine it with older LV and Vision versions.) Otherwise I guess I would get more answers here.
On the other hand, if I ask the manufacturer he will probably say I should use his SDK which I don't want at this point.
Best regards,
mirola

IMAQ USB Close leaves the camera open

Hi,
I hope somebody can help me with that one. I have a DirectShow compliant USB camera, that I got to work with the IMAQ USB VIs. I can acquire images, enumerate the devices and get the options dialog. However calling the IMAQ USB Close VI does seem to have any effect. As the next time I try to call IMAQ USB Open afterwards I got error -1074396024 until I terminate the host process and restart LabVIEW again.
I am using LabVIEW 8.0, on W2k German
I also tried the samples (e.g. Grab.vi) provided with the same effect.
Running a tool that collects system debug messages (send via OutputDebugString) I got 'Export: Break Connect' coming from the IMAQ USB Close VI, but I also see, that the underlying DirectShow Interface doesn't receive any close call. Is there an Interface missing in the DirectShow interface (which?) or is this a bug in the IMAQ USB Interface (not very likely as a lot of guys seem to be happy with it)?
Can anybody help please?
Greetings,
Stefan

Stefan,
below is an excerpt about the system requirements for IMAQ USB:
- Windows 2000/XP (English, Italian,
Japanese, French, Italian, Norwegian, Dutch, Spanish/Portuguese,
Russian, and simple Chinese)
- LabVIEW 7.0 or higher with NI Vision 7.1 or higher for the USB LabVIEW support.
- Vision Assistant 7.1 or higher for the USB Vision Assistant plugin module.
In general IMAQ USB is not supported but I will forward the information to R&D.
The following link povides other possibilities:

IMAQ USB Snap.vi time out

I'm trying to capture an image in LabView using a veo stingray webcam.
I'm using LabView 7.1 with Vission Assistant 7.1. I've attached my
block diagram. When I press run LabView recognizes my camera, but I
always get the following error.
Error -1074396030 occured at IMAQ USB Snap.vi Time Out.
Any suggestions would be appreciated.

The QuickCam is indeed USB. The error appears when the vi is closed without using the IMAQ USB Close.vi (for instance when aborting the execution using the toolbar stop button). So, problem solved. Unfortunatelly this was not the only issue : Now my vi does not crash LV... but returns only a black image...
For professionnal use, I have several NI frame grabbers. For teaching, I don't have a budget for 16 firewire adaptators and cameras . I'll try re-installing the software one more time.
This is not a big problem because as I said before, the grab function is working. However, I don't like giving my students the idea that sometimes only 50 % of LabVIEW functions are working properly.

Error 0xBFF60492 on IMAQ USB snap.vi RT Video not support displaying selected color depth

Attempting to snap a picture with NI-IMAQ for USB in LabVIEW 8.0 using the following procedure.
1)I get the first enumerated camera, 2) open a session, with returned
string [0], 3) start a session, 4) snap a picture and 5) close
vi. My problem is that in step 4 with the IMAQ USB Snap.vi, I get
the following error.
Error -1074396014 occurred at IMAQ USB snap.vi
The image passed is not valid.
Possible Reasons(s):
IMAQ Vision: (Hex 0xBFF60492) RT Video Out does not support displaying the supplied image type at the selected color depth.
I give the snap.vi an Image in from rightclick->Create->Control
or rightclick->Create->Constant. The output image (on the
Front Panel) created by rightclick->Create->Indicator.
LabVIEW should insert the correct data structure to match the expected
input/output, and there is nothing I can that changes he color
depth. The GetImageInfo.vi reports that the camera is set up for
4 Bytes Per Pixel, with the rectangle 352x288.
Also the error message refers to RT Video Out, but I am using USB. This distinction is significant in NI Vision Assistant.

Hello together,
I wanted to use a Sanyo Xacti CG 10 video camara in LabView.
By using the NI-IMAQ for USB Snap I get the following error: IMAQ Vision: (Hex 0xBFF60492) Ungültige Blit-Funktion des Videoausgangs.
Is it possible, that I can not use this camera in LabView?
Thanks a lot for your reply

IMAQ USB CAMERA BLINKING

I'm trying to do a real time inspection with Vision Assistant 8.6 and when I start capturing with IMAQ USB GRAB inside Labview 8.6 the video starts blinking and I can't see for sure what is happening.
Is there any solution to stop it and make the image smooth without blinking?
There is an image below showing the block diagram.I'd appreciate if someone could help me.

Hi, Alex,
You have clear race conditions between Grabbing/Processing/Visualization.
Try to copy image to other buffer, then "blinking" should goes away.
Something like that:
Also remember, that at first grab iteration your image is not valid, because grab occurred after processing.

Imaq usb palet doesn't appear

Hi all,
Are anybody maybe encounter with problem after installation of imaq usb driver, the usb imaq palet doesn't appear :-(
Outside the Labview I succeed to connect by Vision Assistant but in VI Vision Assistant doesn't see usb camera.
Thank you in advance fore help.
Yan

Hi Yan,
This happened to me also. I have two versions of LabView, 8.5.1 activated and 8.6 Evaluation. I installed the driver like three times but I only tried with LabView 8.6 and no palet appeared. Finally, i tried in 8.5.1 activated and it was fine and working properly. If you have more than one version of LabView, my advice is to check them all and see in which one the palet is visible. Other than that, i can't really think of anything else.
Hope this helps,
Sabin

IMAQ USB ON LABVIEUW 2009

hi,
I downloaded Imaq usb driver to use it with LV 2009 student and vision, on LV 8.5 (other pc) it works fine, but on LV 2009 there are no usb pictograms available in the vision menu, the other vision vi's are available.
OS: win 7 and win xp ( won't work on both)
Jeffrey
Solved!
Go to Solution.

Hi Jeffrey,
Starting with Vision Acquisition Software 2009 we integrated the IMAQ USB Support in IMAQdx.
So you should be able to use IMAQdx functions for grapping images from USB Cameras, but keep in mind the need to bei DirektShow compatible.
In former Versions ther was a sepperate Installer for IMAQ USB, that's right.
Hope this helps,
Christian

When i plug the USB for my iPad into my computer it will connect then disconnect over and over again untill i wiggle the usb around alot. This is happening to all my ports. But not on the other computer.

Hi. Whenever i plug my iPad (Happens with ipod and iphone too) to my computer usb for itunes is will connect, then disconnect over and over again. It has happened for a long time but doesnt happen on my other computer. how do i fix this?

If you have a spare cable, try using that. But the fact that this doesn't happen on your other computer (I assume using the same old cable) leads me to conclude that something else is at work. Maybe even the "bad" computer.

I need to access (Ultra) scsi-2 drives but the card is dead. Is there an adapter/converter out there somewhere like my IDE to USB for this? Any other suggestions appreciated.

Might be hard to find, but long ago there were a couple of Firewire<->SCSI adapters, if you have USB2 those might be available also...

I think Belkin made one also.
Might be far cheaper to buy an old Mac or even PC with SCSI.

Have no idea what you are asking about. What hardware issue? What does a USB and a 2007 MacBook Pro have to do with it?

No more than 2 USB for macbook Pro?

Hey everyone,
Isn't there a way to add/use more USB for mac pro? I have a Wacom, external Keyboard, Western Digital External harddrive and Ipod that i would like to use all at once.
thanks all

powered? like plug to the wall?
Yeah it's not just about how many devices can be powered, but also reliability. Some devices just don't work right if they are power starved, and some throw up low-power related error messages all the time if on a bus-powered hub. Wall power ensures that there's enough power for all connected devices and the hub too. I have a Keyspan 4-port that works great and a D-Link 7-port that was flaky as heck.
Another option for you is an ExpressCard/34 that has more USB ports on it. You just slide it in your slot on the left side. Various manufacturers make them. I think they usually have two ports on them. If you want more ports, you'll still need to get a hub.

Functions in IMAQ Vision for Labview same as those in Vision Builder?

Hi all...
i just have a simple question..Does IMAQ Vision for Labview has the same functions of Vision Builder?
I know that with Vision Builder you can develop an application interactively...but does it has more functions than IMAQ Vision?
So if i buy IMAQ Vision can i develop the same kind of applications that i would make with Vision Builder?
I´m specially interested in color matching and color analisys functions.
Thanks

IMAQ Vision has much more than Vision Builder. Basically, VB was created using Vision and they implemented a good number of the functions in a menu driven format. However, there are many more functions available that were not integrated into VB.
Vision does have some good color matching and analysis tools.
