如何將opencv圖像（8UC3）轉換爲char *數組

Question

我有一個RGB圖像。

Mat image; 
image = imread(argv[1], CV_LOAD_IMAGE_COLOR); // Read the file 

現在我需要創建一個UCHAR *從圖像數據數組：我使用加載OpenCV中。 我該怎麼做？

Answer 1

uchar* cv::Mat::data 

pointer to the data 

而且不要忘記，Mat實際行大小可能從寬*的sizeof（元素）不同：

cv::Mat::step is needed because the matrix can be a part of another matrix 
or because there can some padding space in the end of each row for a proper 
alignment.
