Hi,
I want track multiple object.I buy 4 camera licence but i cant find how can i track color based object position.I am traying change Face tracker code but when i run this code i see gray 2 screen.Where is my error ?

Hi,

In CLEYE_COLOR_PROCESSED, PS3Eye gives you 32-bit RGBA pixels. Yout image is 24-bit RGB.

You probably have a problem with the following line:

cvConvertImage(pCapImage, image); 

You could try this instead:

cvtColor(pCapImage, image,  CV_RGBA2RGB); 

Take a look at the following link (http://stackoverflow.com/questions/13624703/opencv-c-convert-rgba-to-hsl-and-then-split-channels).

Also you are mixing IplImage with Mat. You could convert the whole code to use cv::Mat instead.

Hope this helps.

I change my while method to this.  imshow(gelenframe) code shows gray screen. I think i cant transfer pCapImage image.But i cant find how to do this. I can’t try cvtColor because it gives error with my varible. no suitable constructor exists to convert from “IplImage *” to “cv::_InputArray” 

while(_running)
        
{
            cvGetImageRawData
(pCapImage, &pCapBuffer;);
            
CLEyeCameraGetFrame(_cam, pCapBuffer);

            
cvConvertImage(pCapImage, image);
            
            
Mat gelenframe = cvarrToMat(pCapImage);
            
cvShowImage(_windowName, image);
            
imshow("SB Resim",gelenframe);
                 
}

I solved with add this

if (cvWaitKey(30) == 27) //wait for ‘esc’ key press for 30ms. If ‘esc’ key is pressed, break loop
        {
              cout << “esc key is pressed by user” << endl;
              break;
        }
