Unable to change the resolution of the camera without cropping the image #67

Closed JaouadROS closed 3 years ago

JaouadROS commented 6 years ago

I'm using bayer_rggb_image_proc.launch file in which I'm keeping the image_width and image_height to the maximum resolution of the camera. I want to downsample the resolution of the camera to the half so I set subsampling parameter to 2. However I'm getting the error of Failed to set Area Of Interest. I can successfully do the same with ueyedemo and getting the resolution I want. What could be the issue here?

Camera: UI527xCP-C ROS: melodic Ubuntu: 18.04 LTS

Error:

[ERROR] [1527079605.090495031]: Failed to set Area Of Interest (AOI) to 2056 x 1542 with top-left corner at (0, 0) for [camera]

I know this is late, but I am cleaning a bit the repo and closing old issues. This is just the way IDS Cameras work. The image_width/height parameters set something like "the pixels on the sensor" being used to acquire the image. subsampling would be the way to go. Anyway, as this is older, I hope you have solved it.
