Hey Once again,
I have some specific questions related as you could expect from the heading of this post.
So, I have a Teledyne Dalsa Nano c1930 camera. I am trying to acquire the images with 30 fps having image resolution of 1984x1264 using fisheye lens. I am using cvb python for image acquisition.
I have 2 questions and would be thankful if anyone could answer it,
- Why does the Auto brightness does not work, I mean it works in the beginning and later it is always bright and does not auto-adjust. I don’t know the reason, even tried to change the settings from the GeniCam browser but not yet solved the issue, you can see the below image, it get to normal brightness but is than fixed.
Furthermore, I trigger (configure) the auto-brightness grammatically with the following code:
CAMERA_WIDTH=1984 CAMERA_HEIGHT=1264 CAMERA_HORIZONTAL_OFFSET=0 CAMERA_VERTICAL_OFFSET=0 FPS=30 def deviceConfiguration(dev_node_map): dev_node_map['Cust::autoBrightnessMode'].value = "Active" dev_node_map['Std::Width'].value = CAMERA_WIDTH dev_node_map['Std::Height'].value = CAMERA_HEIGHT dev_node_map['Std::AcquisitionFrameRate'].value = FPS dev_node_map['Std::OffsetX'].value = CAMERA_HORIZONTAL_OFFSET dev_node_map['Std::OffsetY'].value = CAMERA_VERTICAL_OFFSET
Now, to exposure time and long time exposure, You can see the blurry images below:
I am beginner in this domain, and did not get it but I what I understand that the exposure time has to be set which is mentioned here can anyone guide me how to set the correct exposure Time and long Time Exposure for 30fps and 1984x1264 resolution. So in the end my images are not blurry.
