将 RGB 数组转换为 Mat (OpenCv) [英] Convert RGB array to Mat (OpenCv)

问题描述

我一直在尝试使用 opencv 转换 Mat 对象中的数组 [R,G,B,..].但是返回错误的数据，有人知道为什么吗?

I've been trying to convert an array [R,G,B,..] in Mat object with opencv. But is returning wrong data, someone knows why?

double data[12] = {0,0,255,0,0,255,0,0,255,0,0,255};
Mat src =  Mat(2,2, CV_16UC3, data);

并返回:

M = 
 [0, 0, 0, 0, 0, 0;
  0, 0, 0, 0, 57344, 16495]

解决了！使用 uchar 代替 double 和 CV_8UC3

Solved! use uchar instead double, and CV_8UC3

推荐答案

我想，你想要:

uchar data[12] = {0,0,255,0,0,255,0,0,255,0,0,255};
Mat src =  Mat(2,2, CV_8UC3, data);
