Question

the carpet/mat should be black无效设置（int argc，char ** argv，RaspiCam_Cv＆camera）{

camera.set ( CAP_PROP_FRAME_WIDTH,  ( "-w",argc,argv,360 ) );
camera.set ( CAP_PROP_FRAME_HEIGHT,  ( "-h",argc,argv,240 ) );
camera.set ( CAP_PROP_BRIGHTNESS, ( "-br",argc,argv,50 ) );
camera.set ( CAP_PROP_CONTRAST ,( "-co",argc,argv,50 ) );
camera.set ( CAP_PROP_SATURATION,  ( "-sa",argc,argv,50 ) );
camera.set ( CAP_PROP_GAIN,  ( "-g",argc,argv ,50 ) );
camera.set ( CAP_PROP_FPS,  ( "-fps",argc,argv,100));
}

void capture() {
camera.grab();
camera.retrieve(frame);
cvtColor(frame, frame, COLOR_BGR2RGB);

}

图像颜色为紫色。它是否必须对COLOR_BGR2RGB做些事情？或者是其他东西？谢谢

这是我正在执行的图像捕获代码。请帮助谢谢。相机是否可能无法正常工作或它是代码。谢谢。它曾经可以正常工作，但是在某个时候变成紫色。

#include <opencv2/opencv.hpp>
#include <raspicam_cv.h>
#include <iostream>
#include <chrono>
#include <ctime>
#include <wiringPi.h>

using namespace std;
using namespace cv;
using namespace raspicam;

Mat frame;

void Setup ( int argc, char **argv, RaspiCam_Cv &Camera )
{
    Camera.set ( CAP_PROP_FRAME_WIDTH,  ( "-w", argc, argv, 400 ));
    Camera.set ( CAP_PROP_FRAME_HEIGHT,  ( "-h", argc, argv, 240 ));
    Camera.set ( CAP_PROP_BRIGHTNESS, ( "-br", argc, argv, 50 ));
    Camera.set ( CAP_PROP_CONTRAST ,( "-co", argc, argv, 50 ) );
    Camera.set ( CAP_PROP_SATURATION,  ( "-sa", argc, argv, 50 ) );
    Camera.set ( CAP_PROP_GAIN,  ( "-g", argc, argv,50 ) );
    Camera.set ( CAP_PROP_FPS,  ( "-fps", argc,argv,0));

}


int main(int argc, char** argv)
{
    RaspiCam_Cv Camera;
    Setup(argc, argv, Camera);
    cout<<"Connecting to camera"<<endl;
    if (!Camera.open())
    {
         cout<<"Failed to Connect"<<endl;
    }

 cout<<"Camera Id = "<<Camera.getId()<<endl;

 for (int i=0; i<40; i++)
 {
  Camera.grab();
  Camera.retrieve(frame);
  cvtColor(frame,frame, COLOR_BGR2GRAY);
  imshow("Sample", frame);
  imwrite("Stop"+to_string(i)+".jpg" , frame);
  waitKey();
 }

    return 0;
}
