About the frame rate problem of crossroad_camera_demo

[STATEABC]

I am using FPGA AI Suite to run crossroad_camera_demo in OpenVINO.

The models I use are:
person-vehicle-bike-detection-crossroad-1016
person-attributes-recognition-crossroad-0230
person-reidentification-retail-0288

The device of person-vehicle-bike-detection-crossroad-1016 is HETERO:FPGA,CPU, and the devices of person-attributes-recognition-crossroad-0230 and person-reidentification-retail-0288 are CPU.

If all three models are run on the CPU, the average frame rate is around 45
If the main recognition model 1016 is run through HETERP:FPGA,CPU, and the other two are run through the CPU, the frame rate will not exceed 20

But the person-vehicle-bike-detection-crossroad-1016 model is not divided into many subgraphs. According to the message printed in the terminal: The input graph is split into 2 subgraph(s), CPU 1 FPGA 1.

I want to know where else will affect the frame rate of the model? And how can I improve the frame rate?

Any help would be greatly appreciated, thank you!

Hi,

May I know which AI Suite version, FPGA board and bitstream are you using to run the demo?

HI,

Can you provide me the detail information on the bitstream and board use to performed the testing?
