Windows Error 0xe06d7363 (WinError -529697949) when setting gain (Python sample code on Windows)
gwappa opened this issue · comments
Hi,
Thanks for providing the sample code like this!
I am trying to run tis-OpenCV.py, but the script keeps shutting down at line 79 (Python raises an OSError, with the error code as shown above):
Camera.SetPropertyValue("Gain", "Value", 1)When I comment the line out, everything else works out as expected, up to the point when I hit Ctrl-C.
Do you have any idea about what is going on?
In case, below is the description of my environment:
- Windows 10 (probably the latest build as of July 2021)
- Anaconda
- Python 3.8.10
- NumPy 1.20.3
- OpenCV 4.0.1
- IC-Imaging-Control-Samples bb2368
- Camera: DMK 33UP1300 (Driver version: 5.0.1.1607), through a USB3 cable
EDITED: forgot to mention about the acquisition configs. I tried several grayscale settings (Y16, full HD or 640p) with some frame rates (~30 fps, ~50 fps or ~60 fps), and obtained the same results.
Thanks,
Keisuke
The gain minimum value of the DMK 33UP1300 is 144. Not 1.
Please try 144.
Oh, I see. The line worked after I change the value to 144.
Is there a way to check the valid range of values, either programmatically or on the manual?
Thanks a lot!
Yes, there should be a range or a minimum function.
At least, it is in the DLL. I am not sure, whether it is imported in Pyhton. (That is always double work,)
I see, there are no property range / min / max functions imported in tisgrabber. py.
The function to be imported from the DLL is IC_GetPropertyValueRange. See "tisgrabber.h" for a short documentation of this function.
Yeah, now I see it myself. Well, it seems anyway doable to export it to python for my own purpose anyway.
Everything becomes clear by now. Thanks again for your response!
