Advise for Qthreads and the opencv frame processing sequentially

[Beatrix]

Hi,

I have an object detector thread (created with move thread) and looks slow to catch up current fps from camera.

I want to separate stream capture (cv::cap) 1 thread and it will distribute the task (object detection) to the other threads (6 threads).

1 thread -> UI
1 thread for stream capture and sending the frames to the worker threads
6 threads for object detection and send back to results to the capture thread .

But I dont want to lose frame sequence. I mean I wan to show results in the screen as normal frame sequence. If som thread sends the processed frame before the previous frame it should wait its ques to show.

Basicly:
send frame numbers : 1 ,2 , 3 ,4 ,5

get result and show them as soon as awailable in same sequence 1 , 2 , 3 ,4

suggestions :)

Hi,

Based on your other thread: big GPU + stronger machine. 6 streams with high definition images can't be processed in real time if you don't have the hardware that follows.

This is another issue. Other thread for 6 live stream just showing on the screen through opencv.

This one only one stream an 8 cores i7 machine.

I wan to utilize all possible cores for object detection which send them individual frames and get back to show on the screen.

How can I show them again in right sequence

My recommendation still stands: you should consider exploiting a GPU to speed up processing of your images rather than parallelising on your CPUs.

try to keep budget down..
1080ti almost 800 usd..

if I have 8 cores I should used it.
