OpenCV Error: Assertion failed
OpenCV越界問題:
OpenCVError:Assertion failed (0<= roi.x &&0<= roi.width && roi.x + roi.width <= m.cols &&0<= roi.y &&0<= roi.height && roi.y + roi.height <= m.rows) in cv::Mat::Mat(const cv::Mat&,const cv::Rect&),
file C:/build/2_4_PackSlave-win32 -vc11-shared/opencv/modules/core/src/matrix.cpp, line 323
出現問題的原因是:
影象的ROI區域超過了影象的尺寸,即 roi.x + roi.width > m.cols && roi.y + roi.height > m.rows

看了好多帖子,都說什麼路徑問題,要改成絕對路徑等等。這固然沒錯,但是相對路徑的話,圖片要放在和.cpp檔案的同一個資料夾下。 而且,剛買的電腦圖片格式沒有後綴.jpg,如圖所示。但是在程式碼裡要寫成1.jpg。 #include <iostream> using names

程式設計報錯 OpenCV Error:Assertion failed
錯誤出現:呼叫網路攝像頭,將捕獲到的彩色幀轉變成灰度幀時,呼叫cvtColor函式,出現錯誤。 分析:可能原由,攝像頭呼叫獲取幀影象失敗,攝像頭原因,之前舊攝像頭未出現此錯誤,購買新的攝像頭出現此錯誤。 解決:暫未找到根治方法,但是通過重新插入攝像頭或等待一會執行程式
