IMAQ DT3155 driver
Hi,
I am looking for a Labview VI for my DT3155 frame grabber from Data
Translation.
The one from Imagemill or alliance vision is too expensive.
Can anyone help me with an example VI to capture a single image using the
Frame Grabber SDK. I can then modify to my needs.
Thanks in advance.

> Herbert,
I am using the cheap "falcon" frame grabber which is available from several
vendors. It comes with a powerful DLL which can be linked easily to LV and
imaq vision, no need to know which chip is underlying (the Bt848 by the
way). A simple C-code moves the video image to an imaq image, all within
the LV environment.
Best wishes,
Detlef

I have an imaging system that includes a Pt Grey Dragonfly camera. I know that using the manufactures SDK, I can set different camera parameters outside of the DCAM specs by setting camera registers. If I am using version 1.1 of the IMAQ 1394 driver can I set, say the frame rate to a value outside the DCAM specs?

Camera unable to grab while running in 30 fps through ImaqDx driver.
Hi,
I am using 3 cameras running on Imaq Dx driver.
The video mode is 800 X 600 YUV 4:2:2 30fps, speed 800Mbps.
2 cameras are connected on express 1394b and other is connected to PCI 1394b.
All 3 cameras are triggered through hardware trigger.
After some iterations the camera stops transmitting the image
Everytime we are finding the problem repeating in camera connected to PCI card other than the camera connected to the Express card.Definitely there is no problem with the PCI card..We had contacted the manufacturer i.e Point Grey,but they are telling the problem is with the Imaqdx driver.So kindly reply us back faster.
Regards
Abhishek VermaHello Abhishek,
This could be due to the Bandwidth limitations in Firewire. I have attached a Firewire Bandwidth Allocation file. Use that and identify how much is the maximum speed you can achieve for your configuration.

IMAQ 1394 version 2.0 - setting the shutter integration time
I am using IMAQ 1394 version 2.0 with a CCDdirect firewire camera. I am trying unsuccessfully to set the shutter attribute in absolute mode to a value of several seconds. I cant seem to get an integration time greater then .13 seconds to be accepted, even when I try to set it in MAX. Any suggestions would be appreciated. I am also using Labview 7.1 Developers suite
thanks,
RonenHello Ronen,
I'm not familiar with CCDdirect cameras. Is there a particular model that you are using?
What happens when you set the value greater than 0.13 seconds?
Some cameras that I have worked with in the past require that the camera be placed in an "extended" shutter mode in order to use long integration times. Does your camera offer any additional shutter modes that will allow you to increase this value?
What shutter/integration time attributes show up in MAX? These attributes and there values/ranges are read directly in from the camera. I have also worked with some cameras in the past that have additional attributes that do not show up in MAX. Typically these are attributes/features that are not part of the DCAM compliance. MAX and the IMAQ 1394 driver only access DCAM specific features. If the correct values do not show up, perhaps the camera manufacturer can show you how to set these attributes.
Let me know the answers to the above questions if you are still unable to accomplish what you need. I would be more than happy to help out in any way possible.

Ni-imaq for 1394 camera support for sony dv cameras
Hello,
I am wondering if there is any way to capture images from my sony mini dv recorder (DCR-PC101 NTSC) to Labview. Is it possible through ni-imaq for 1394?
Thank You.Hi charliec,
Support for mini dv cameras is not currently available with the IMAQ 1394 driver. The only way to access the files captured by the camera are to download them to disk then open them with LabVIEW (or some other programming environment).

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.
YanHi 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,

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,

Buffered ring acquisition with IMAQ 1394 2.0 (beta)
Hi,
the IMAQ 1394 low level buffer access topic comes up again. National Instruments promised that low level buffer
access will be feasible in the 2.0 (beta) version of the IMAQ 1394 driver. However, I still encounter problems.
I want to run a continuous ring acquisition. The ring shall consist of 40 buffer cells. I configure the acquisition
using IMAQ 1394 configure acquisition.vi and wiring "40" to "number of buffers" and "continuous" to "continuous?".
If I am testing the ring, it appears that the ring only has 20 buffer cells. After an image had been written into cell
no. 19, the next image is written into cell no. 0 and not into no. 20.
Is there a maximum number of buffer cells implemented? In the online help, nothing is written about such a fact. In
addition, the help statements are quite puzzling. There they write:
Use the Continuous? and Number of buffers parameters to select the type of acquisition that you want to configure,
as follows:
Snap One-shot; one buffer
Sequence One-shot; multiple buffers
Grab Continuous; one buffer
The combination of "continuous" and "one buffer"
sounds rather antithetically. Is any beta tester around there who can make sense out of this?
Thankful for any hint,
PeterWhat I want to do is to setup the camera and store the settings to the camera memory and do a flat-field calibration of the camera (and maybe also store the calibration image in the camera).
I will use your method to handle the default settings. Thanks!!!
Then I will remove the camera from the calibration setup and use it in a machine performing measurements not using LabVIEW. I could make all the setup in the machine again but that would mean more work than to use LabVIEWs functionality (I'm just lazy).
I just want to be sure that all settings have reached the camera memory and that they were stored there. It does not seem that the Property Node communicates directly with the camera like the "IMAQ1394 Write Registers" command does.

Triger/transmit light from projector when i sanp from camera with IMAQ PCI 1407
I want to activate projector to emit light when i snap
Take a look at the low level snap example. Put the IMAQ Trigger Drive VI between the IMAQ Configure Buffer and IMAQ Start and set the "trigger drive" input to asserted. This will drive the trigger line as soon as the VI is called. Alternately, you could choose another condition such as "acquisition done" to drive the trigger after the frame is acquired. Please note, as soon as you call IMAQ Close, the trigger line will return to the default tri-state.

How do I read the number of dropped frames in a 1394 session?
I'm using a C program to acquire image data using the imaq1394 library. I am dropping frames at 30FPS and want to use the imaq1394GetAttributes call with the IMG1394_ATTR_LOST_BUFFER_NB parameter to read the number of dropped frames. I am doing this at the end of the acquisition before the camera is closed. The value always comes back as 0. What is wrong? Here is the line that makes the call:
imaq1394GetAttribute(Sid, IMG1394_ATTR_LOST_BUFFER_NB, (unsigned long *) &lDroppedFrames);
Thanks in advance...Hello spcmicro,
Thank you for the email.
For the IMAQ 1394 driver (version 1.0), the lost buffer attribute does not work properly.
- The issue is not known to the developer lead, and it will be investigated for the next release of the IMAQ 1394 driver.
Please let me know if you have any additional questions,

How to connect external trigger PCIe1427
Hi,
We are working with PCIe 1427 frame grabber and a IR camera with Cameralink Standard. Our camera has got asynchronous reset at CC3, so we have given external trigger 2 in NI MAX and successfully able to grab the video. But we need to implement the same using Labview application, so tried to use imaq configure trigger3, imaq trigger drive VI's and unsuccessful in resetting the camera and grabbing video.
We are using IMAQ 4.9 driver and Vision development module with Labview development suite 2013 SP1.
Kindly provide any solutions.
with regards,
SriHi all,

Synchroniz​e a gyro sensor with a video camera
Hello,
I going to start a project on real-time video stabilization based on gyro sensor.
I am planning to use a video camera which does not contain an external trigger.
does anyone have an idea in order to synchronize the image frames with the data from the gyro sensor.
Thanks in advanceHi tahraoui,
If you are ok with your camera and gyro having a fixed, but non-zero, phase difference, then you can route the VSYNC signal (called "Vertical Synchronization Signal" in the IMAQ Trigger Drive VI) from the IMAQ board which is acquiring from the camera across a RTSI line to the DAQ board that is acquiring data from the gyro, and use that signal as the start trigger for the gyro acquisition.
The VSYNC signal is generated by the camera, which typically will generate it after the exposure, and routed through the IMAQ board, which will induce a board-specific group delay. As a result, the trigger you see on the RTSI line will lag the start of the exposure time by some period of time, but for many applications, it is possible to calibrate that delay out.

Hello Robert,
You can find out more information about this error at the following post.
what does Error 1706 mean during LabView 6.1 installation
This error is not specific to the install of LabVIEW but with the upgrade of the IMAQ device driver.
Please let me know if you have any other questions
