opencv hand openpose

使用opencv c++ 来调用caffemodel

使用opencv 得dnn 模块调用 caffemodel得程序，图片自己输入就行，不做过多得解释，看代码清单。

定义手指关节点

const int POSE_PAIRS[20][2] =
{
{0,1}, {1,2}, {2,3}, {3,4}, // thumb
{0,5}, {5,6}, {6,7}, {7,8}, // index
{0,9}, {9,10}, {10,11}, {11,12}, // middle
{0,13}, {13,14}, {14,15}, {15,16}, // ring
{0,17}, {17,18}, {18,19}, {19,20} // small
};

string protoFile = “hand/pose_deploy.prototxt”;
string weightsFile = “hand/pose_iter_102000.caffemodel”;

int nPoints = 22;
