寻找包裹轮廓的最小正矩形:boundingRect 函数 返回矩阵应满足:① 轮廓上的点均在矩阵空间内.② 矩阵是正矩阵(矩形的边界与图像边界平行). Rect boundingRect(InputArray points); 唯一一个参数是输入的二维点集,可以是 vector 或 Mat 类型. 代码示例: #include<opencv.hpp> #include<iostream> using namespace cv; using namespace std; int ma
当我们得到对象轮廓后,可用boundingRect()得到包覆此轮廓的最小正矩形,minAreaRect()得到包覆轮廓的最小斜矩形,minEnclosingCircle()得到包覆此轮廓的最小圆形,这些函式协助我们填补空隙,或者作进一步的对象辨识,boundingRect()函式返回的是正矩形,所以如果对象有倾斜的情形,返回的可能不是我们想要的结果. Rect boundingRect(InputArray points) points:输入信息,可以为包含点的容器(vector)或是Mat.
