How to improve Basler camera image delay

Hi everyone,

Sorry for my poor English.

I use two Basler cameras “a2A1920-160ucBAS” to implement real-time object detect, now I can do it with GPU and the time of processing the two pictures at the same time is at most 20ms, But there is a serious problem, it have a long delay.

My experiment setting is use two Basler cameras to capture image and then processing this two image with OpenCV in C++, then calculate the object’s coordinate and transmit data to my MPU (STM32F407) with CAN bus. I compare this data with ground truth, and it delay about 500ms like phase lag. It means every image I get is 500ms ago. But I only take 20ms to do image processing and CAN bus transmit. Is the other time spend on image transmit？

Please assist me in solving this problem.
Thank you and sorry for my poor English again.

Hi,
Please execute sudo jetson_clocks to run system at maximum performance. See if there is improvement to run hardware engines at maximum clock. For checking system status, you can execute sudo tegrastats
