azure kinect drops frames #1127

Closed yellowfisher closed 4 years ago

yellowfisher commented 4 years ago

I've record color and depth stream time stamp, the nearest two frames have 100ms interval，that means 3 frame drops, is this normal? 1583982844(1)

There might be a couple when starting the stream, but after the first second I would expect no drops from a PC that meets the performance specs.

thanks for your quick reply, as picture shows, it drops from the frame 1482. My computer has i7-9700k cpu, 16gb memory, 1T ssd and nvdia rtx 2080 graphics card.

I'll do a deep test and create complete request later. There's another problem here, i get skeleton data with k4abt_frame_get_body_skeleton, map 3d position data to 2d rgb data with k4a_calibration_3d_to_2d, and at last draw skeleton with opencv cv::line , but the skeleton just out of body, did i do it wrong? skeleton

I would say if you are going to do a new test and you suspect an issue. Try with one of our tools first. streaming_samples.exe and Throughput_perf are useful for verifying everything works as expected.
