opencv基本数据类型

•   cv::Vec<>模板（固定向量类）：

        cv::Vec{2,3,4,6}{b,w,s,i,f,d}

     解释

　　 b  unsigned char

        w unsigned short

        s  short

        i  int

　　f float

　　d double

//使用示例： //默认构造函数 cv::Vec2s v2s; cv::Vec3i v3i;   //拷贝构造函数 cv::Vec3i v3i_a(v3i);   //值构造函数 cv::Vec3f v3f(1.0, 3.0, 6.0); cv::Vec2d v2d(1.0, 2.0);   //成员访问，可用[] float elem_v3f = v3f[0];   //向量叉乘 cv::Vec3d v3d_b(1, 0, 0); cv::Vec3d v3d_c(0, 1, 0); cv::Vec3d v3d_bcc = v3d_b.cross(v3d_c); std::cout<<v3d_bcc<<std::endl;//对<<进行了运算符重载
