[英]I can't run camshift demo in openCV
我在VS2010中安裝了openCV2.3.1。 我可以在openCV中讀取圖像而沒有任何錯誤。 但是當我從文件夾open / samples / cpp運行camshiftdemo時。 它顯示了這個錯誤。

當我評論這一行// RotatedRect trackBox = CamShift(backproj,trackWindow,TermCriteria(CV_TERMCRIT_EPS | CV_TERMCRIT_ITER,10,1)); 沒錯。
在我的另一個代碼中它顯示這樣的錯誤。 這是我的測試手段的代碼
int main()
{
// Read reference image
cv::Mat image= cv::imread("Desert.jpg");
if (!image.data)
return 0;
// Define ROI
cv::Mat imageROI= image(cv::Rect(110,260,35,40));
cv::rectangle(image, cv::Rect(110,260,35,40),cv::Scalar(0,0,255));
// Display image
cv::namedWindow("Image");
cv::imshow("Image",image);
// Get the Hue histogram
int minSat=65;
ColorHistogram hc;
//cv::MatND colorhist= hc.getHueHistogram(imageROI,minSat);
ObjectFinder finder;
//finder.setHistogram(colorhist);
finder.setThreshold(0.2f);
// Convert to HSV space
cv::Mat hsv;
cv::cvtColor(image, hsv, CV_BGR2HSV);
// Split the image
vector<cv::Mat> v;
cv::split(hsv,v);
// Eliminate pixels with low saturation
cv::threshold(v[1],v[1],minSat,255,cv::THRESH_BINARY);
cv::namedWindow("Saturation");
cv::imshow("Saturation",v[1]);
// Get back-projection of hue histogram
int ch[1]={0};
cv::Mat result= finder.find(hsv,0.0f,180.0f,ch,1);
cv::namedWindow("Result Hue");
cv::imshow("Result Hue",result);
cv::bitwise_and(result,v[1],result);
cv::namedWindow("Result Hue and");
cv::imshow("Result Hue and",result);
// Second image
image= cv::imread("Desert.jpg");
// Display image
cv::namedWindow("Image 2");
cv::imshow("Image 2",image);
// Convert to HSV space
cv::cvtColor(image, hsv, CV_BGR2HSV);
// Split the image
cv::split(hsv,v);
// Eliminate pixels with low saturation
cv::threshold(v[1],v[1],minSat,255,cv::THRESH_BINARY);
cv::namedWindow("Saturation");
cv::imshow("Saturation",v[1]);
// Get back-projection of hue histogram
result= finder.find(hsv,0.0f,180.0f,ch,1);
cv::namedWindow("Result Hue");
cv::imshow("Result Hue",result);
// Eliminate low stauration pixels
cv::bitwise_and(result,v[1],result);
cv::namedWindow("Result Hue and");
cv::imshow("Result Hue and",result);
// Get back-projection of hue histogram
finder.setThreshold(-1.0f);
result= finder.find(hsv,0.0f,180.0f,ch,1);
cv::bitwise_and(result,v[1],result);
cv::namedWindow("Result Hue and raw");
cv::imshow("Result Hue and raw",result);
cv::Rect rect(110,260,35,40);
cv::rectangle(image, rect, cv::Scalar(0,0,255));
cv::TermCriteria criteria(cv::TermCriteria::MAX_ITER,10,0.01);
// cout << "meanshift= " << cv::meanShift(result,rect,criteria) << endl;
cv::rectangle(image, rect, cv::Scalar(0,255,0));
// Display image
cv::namedWindow("Image 2 result");
cv::imshow("Image 2 result",image);
cv::waitKey();
return 0;
}
當我運行此代碼時,它顯示此錯誤。

CamShift和meanShift方法是視頻\\跟蹤模塊的一部分,因此您可能忘記鏈接opencv_videoXXX.lib
在OpenCV 3.2的情況下添加鏈接為'-lopencv_video'
