jcramer / pygige-v Goto Github PK

Working great in Linux.
I have some windows dependency for the development. Do you have any solution for windows.

Hi,

Looks unreal - Thankyou - I was just wondering what state this code is in. I was hoping to build a small app on this driver, and just wanted to make sure it was going to work before buying cameras. Was looking through and found the GevGetImageBuffer function didn't look quite finished. Is this the primary way for retrieving images? And does it work?

Thanks in Advance!

Hello,

I found your project earlier and really liked the approach. It is a fair bit faster than what I had made previously to bring Dalsa cameras into python but I noted some issues. I went through and fixed what I could over the weekend. I have included it in my repo.

I'm not sure if this project is still supported but I would like to assist with it if possible.

not able to access multiple gigeV camera in python.
I have imported the pygigeV class
ctx= gev()
print ctx.GevGetDeviceCount()
print ctx.GevGetCameraList()

Returning memory allocation error when two cameras are connected. but working fine with single camera.

Please let me know does it not support multiple cameras?

Tried the test.py and got the following error:

It is not getting the height right,

Hi, it seems that this wrapper does not support Bayer conversion, am I right?
I can only get a grayscale image in my DALSA Nano-C2420.

The C++ code for this conversion in the examples of the GigE-V SDK looks like this:

context.format = Convert_SaperaFormat_To_X11( pixFormat);
context.depth = pixDepth;
context.convertBuffer = malloc((maxWidth * maxHeight * ((pixDepth + 7)/8)));
context.convertFormat = TRUE;

Is there any way to achieve the same (colored image) with this wrapper?

The frame grabbing is improper and lagging.

Working fine while running the code in C.
Facing problem in Python code.
