OpenCV Error: Assertion failed (type == B.type() && (type == CV_32FC1 || type == CV_64FC1 || type ==

最近切換到64位系統上，執行以前的程式真是各種bug不停啊，主要還是系統位數導致的，先看下面這個錯誤

OpenCVError:Assertion failed (type == B.type()&&(type == CV_32FC1 || type == CV_64FC1 ||
type == CV_32FC2 || type == CV_64FC2))in gemm, file /build/buildd/opencv-2.3.1/modules/core/src/matmul.cpp, line 711

這個錯誤是單應矩陣H於座標向量x相乘引起的，二者型別不一致導致，由於之前32位系統，findHomography函式預設返回CV_32F型別的單應矩陣，與CV_32F型別的x相乘沒有問題，但是64位系統上預設返回CV_64F型別的H，與x相乘就會有問題。這也是我輸出H的型別

cout<<H.type()<<endl;

才發現H的型別不一致的。唉，被類似的問題整了幾天了。。。

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

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
