apogee camera

[vsa]

Hi there,

I have an apogee camera (U2) and a labview program that company sent with that.

Right now I can take an image with Intensity Graph but I need to take an image with image display, I am not good in Labview programming.

I attached the Labview code, if you know the solution please let me know what should I do?

thanks

Hi vsa

To use your camera first you need the IMAQdx driver installed make sure you have it. After that you can use the Examples on your LabVIEW 2012 Example finder to see a small example on which you can start programing. You can find a very usefull one on Help>>Find Examples, when the Example Finder launches go to the search tab and type IMAQdx, many examples will appear I can recomend the Grab.vi as a good start.

Any questions let me know

Hi JuDa

thanks for your reply

yes I have that driver and also use them like code that I attach but it didn t work and I could not see image.

also I serch in example but I did not find any usufull things.Grab.vi has only one example ,Isn t it?

Hi vsa

Whats your camera model?? What kind of acquisition do you need?? continuous or snapshots?? How are you connecting the camera to your PC??

[vsa]

my camera is Apogee CCD camera and Alta series and model of that is U2

labview program that company sent with that is good for biginning my work but I need to add a lot of things like Binning, Trigger and.....

I think if I use image display I can work easily.

but maybe I am not true, ok , please forget my past postes and can you help me to use binning and trigger in my code please?

I attach both of them.

in binning code, I have circle of image and I want to use binning 2*2 for see the  good resolution.

in trigger code, I have same program for take image but I need add trigger for use LVTTl voltag when I need.

sorry JuDa, I am new in LabVIEW and really need your help.

Thanks a lot

Hi vsa

There are two ways to use and program your camera, the first one is the one you are using. This method is using the Apogee Camera driver, this driver has a library of functions that you are accesing with the different property nodes you have in your code. Each property node has its own parameters to configure and you can access the property node help with (ctrl+h) and placing your mouse over the property node.

The second method is using the IMAQdx functions that com with the IMAQdx driver the only thing we have to check is if the camera is supported by IMAQdx I´ll check and send you the answer.

You can also transform the Data you are managing to a picture instead of an intensity graph with Function Palette>>Programming>>Graphic and Sound>>Picture Functions>>Draw unflattened Pixmap.

I´m sending you the code of triggering and binning merged.

Hi JuDa

thanks for your comment, I think my camera supported by IMAQ.

about your first method, I know I shoud use this Icon but unfortunately I don t know which one is the first and also can  I mix this Icon whit IMAX?

in this tutorial of camera that attached is told : you can use forexample  RoiBinningH for Horizontal Binning in the Roi area but I did not know use that where is my program!?

Hi VSA

Sorry I do not understand what you mean... Your program is already using Binning in the property nodes RoiBinning but the Binning will decrease resolution to eliminate noise in your image. Have you tried the Vision Assistant instead of the Camera Driver?? What is the main Goal of your program??? to recomend you what is the best solution.

Hi Juda

I used in my program some nodes like RoiBinning as I read in tutorial of my camera but it did not work.

I mean I nead add another thing becuase my code is not complete but I am new in LabVIEW so I do not know how can I use the IMAQ as you said.

I have another question: can I write my code without the IMAQ driver and how can I do that?

thanks so much

Hi VSA 

Is everything else working?? Can you acquire a single image?? If it is just the binning we can perform some troubleshooting to find what is happening. You need IMAQdx to program your camera, If you want to use your camera with IMAQ I´ll send you some examples and tutorials. Try first detecting the camera from the Measurement and Automation Explorer (MAX) a program from National Instruments that will help us detect and test some of our devices. Look under IMAQdx for your camera.
