c++ opencv 函数计时

不多bb

    
    double clock_dur;
    clock_t clock_start, clock_end;

    //计时===========================================================================================
    clock_start = clock();
    


    int ret = find_line(img, rotrect, fparam);
    std::cout << ret << std::endl;

    //结束===========================================================================================
    clock_end = clock();
    std::cout << " find time	" << (double)(clock_end - clock_start) / CLOCKS_PER_SEC * 1000 << "ms	" << std::endl;
