[object_following] The camera has a delay of 1 to 2s #20

Open Wei666-ui opened 2 years ago

Wei666-ui commented 2 years ago

Hello, In the live_demo.ipynb file in the object_following project, I found that the camera has a delay of 1 to 2s after the project starts.This leads to the inability to track the human body very well. {camera.unobserve_all() camera.observe(execute, names='value')}.After running the code to connect the camera frame update, I found that there is a delay in the image returned by the camera.

1.I didn't find a proper solution online. 2.Other projects are working great, which is great. For example, the collision_avoidance project runs perfectly, the camera has no delay and the recognition is also very fast.So it's not a network and camera or jetbot device issue. 3.My device is jetbot+jetson nano 2GB. At the same time I have not modified the project.

I would like to know how to improve this situation, thanks.If my description is not clear, please let me know too.

@Wei666-ui Sorry for the late response. I'll check if it can be reproduced. Please note that this project is for Jetson Nano Mouse and tested only with Jetson Nano 4GB Dev. Kit only. If the problem only occurs with JetBot + Jetson Nano 2GB Dev. Kit, we may not be able to investigate it.

I tested and found that it could be delayed by almost 1 second. I'll check the details.
