Input image modification

martin181818

Hi community,

I am working on the people tracker and counter project. Is there any way to modify the input rgb image from the camera as source (without using the video argument) to darken a part of the image ?
I need to darken the lower part to avoid tracking and detection below the middle line.

Hi martin181818
I don't think you can specify that on the camera node itself, but something like

colormap = pipeline.create(dai.node.ImageManip)
colormap.initialConfig.setCropRect(0, 0, 1, 0.5)
colormap.initialConfig.setResizeThumbnail(300, 300)

could work. Essentially passing the preview through the imagemanip node.

Hope this helps,
Jaka
