tip for Depth-people-counting

TolqinjonRahimov

Hi i have successfully used https://github.com/luxonis/depthai-experiments/tree/master/gen2-depth-people-counting example through OAK-D camera but i don't understand how to use it during live streaming.What advice can you give me?

Hi TolqinjonRahimov
Switch the replay with camera nodes:

Remove anything that has to do with replay
Add left and right mono cameras and link them together inside stereo_depth node.

Everything else can pretty much stay the same.

pipeline = dai.Pipeline()

#create left and right cameras

leftCam = pipeline.createMonoCamera()
leftCam.setBoardSocket(dai.CameraBoardSocket.LEFT)
leftCam.setResolution(dai.MonoCameraProperties.SensorResolution.THE_720_P)

rightCam = pipeline.createMonoCamera()
rightCam.setBoardSocket(dai.CameraBoardSocket.RIGHT)
rightCam.setResolution(dai.MonoCameraProperties.SensorResolution.THE_720_P)

#create stereo node
stereo = pipeline.createStereoDepth()
stereo.setConfidenceThreshold(200)

stereo.initialConfig.setMedianFilter(dai.StereoDepthProperties.MedianFilter.KERNEL_7x7) # KERNEL_7x7 default
stereo.setLeftRightCheck(True)
# nodes.stereo.setSubpixel(True)

leftCam.out.link(stereo.left)
rightCam.out.link(stereo.right)

Hope this helps,

jakaskerl tried using this code but i got RuntimeError: Stereo Depth(0) - No output of Stereo Depth is connected/used!

thanks for your attention. I will try to use it

Hi TolqinjonRahimov
Seems like you didn't link the stereo depth node to xlink. Maybe try using pipeline graph to check whether all wanted connections were made.

I'm currently also working on porting this experiment to depthai_sdk, where switching between replay and stream is much simpler. I'll add the link to repo if you are interested.

Hope this helps,
Jaka

jakaskerl I would be happy if you could add a link
