Detect the depth of a ROI in RGB camera

NhanNgo

Hi all,

I have a ROI in RGB frame, please give me some advice to get the depth of that ROI.

Many thanks,

Nhan

Hi NhanNgo
Are you able to use the stereo cameras? If so, check this example: https://docs.luxonis.com/projects/api/en/latest/samples/SpatialDetection/spatial_location_calculator/ and add
stereo.setLeftRightCheck(True) stereo.setDepthAlign(dai.CameraBoardSocket.RGB)
[source]

If not, you can use something like https://github.com/dwofk/fast-depth (we have it at luxonis model zoo for quick implementation using blobconverter).

Hope this helps,
Jaka

Hi Jakaskerl,

Yes, I'm using the OAK-D, so I able to use the stereo cameras.

So I just need to set the code "stereo.setLeftRightCheck(True) stereo.setDepthAlign(dai.CameraBoardSocket.RGB)" then put the ROI (in RGB frame) into the SpatialLocationCalculator, is it correct? Do I need to configure the other things?

Thanks for your help.

Hi NhanNgo
You might need to add some focus control. Just follow https://docs.luxonis.com/projects/api/en/latest/samples/StereoDepth/rgb_depth_aligned/ and you should be good 🙂

Thanks,
