Hi erik , Thank you for your prompt reply.

After reviewing my software, as you pointed out, I found that PeopleTraker using Poll was not working properly.

The reason I started considering Poll is because I want to use the OAK-1 footage in other function.

Therefore, I tried to thread it and communicate with Queue, but when I started it with a thread, the next thread could not be started, and it didn't go well.

oak.start(blocking=False) is using.

I couldn't identify the cause, so I thought of using polling processing to include processing that intentionally yields to other threads.

If you have any useful information for threading "with OakCamera() as oak:", please let me know.

Thank you

Hello,

I'm running the PeopleTraker sample on the OAK-1.

The PeopleTrasker sample uses a callback. (code 1)

I'm trying to get it working without callbacks (using poll). (code 2)

I would like to use a video file on my PC in the same experiment as Code 1. Please tell me how to set it up.

Is it the code part of the (*) part?

Thank you.

===========================================================

with OakCamera(replay="videofile.mp4") as oak:

    :

    :

def cb(packet: TrackerPacket, vis: Visualizer):

    :

    :

oak.visualize(tracker.out.tracker, callback=cb)

oak.start(blocking=True)

===========================================================


[code 2]

===========================================================

color = oak.create_camera('color')

    :

    :

features = pipeline.create(dai.node.FeatureTracker) # Create new pipeline nodes

color.node.video.link(features.inputImage)

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^(\*)

    :

    :

oak.start()



q = oak.device.getOutputQueue('features') # Create output queue after calling start()

while oak.running():

    if q.has():

        result = q.get()

    oak.poll()

===========================================================

Hello jakaskerl

Thanks for your advice.

I would like to try it.

If it goes well, I will write again here.

Hello Erik,

I am developing an automatic counting system for entering and exiting people.

The system performs continuous operation (does not turn off power).

Assuming daily measurements.

I'm considering people_tracker, but I've checked IDs up to 70000 and above.

I will also leave a log of the image associated with the ID, so if the ID becomes tens of thousands, the ID display of the video will become complicated, and I would like to do something about it.

Ideally, I would like to be able to reset the ID to 0 at midnight.

I would be happy if you could tell me if you have any good ideas.

Hello,

I'm trying people-tracker on the OAK-1.

I'd like to record the ID assigned to the detected person, but I want to limit the maximum number.

Please let me know if there is a way to reset the ID to 1.

Thank you.
