1.1 Function Documentation - boxPoints()

void cv::boxPoints	(RotatedRect box,
OutputArray 	points 
)

Python

points = cv.boxPoints(box[, points])

#include 

Finds the four vertices of a rotated rect. Useful to draw the rotated rectangle.
查找旋转的矩形的四个顶点。绘制旋转的矩形很有用。

The function finds the four vertices of a rotated rectangle. This function is useful to draw the rectangle. In C++, instead of using this function, you can directly use RotatedRect::points method. Please visit the tutorial on Creating Bounding rotated boxes and ellipses for contours for more information.
该函数查找旋转矩形的四个顶点。此功能对于绘制矩形很有用。在 C++ 中，可以直接使用 RotatedRect::points 方法来代替使用此函数。请访问有关为轮廓创建边界旋转框和椭圆的教程以获取更多信息。

vertice：n. 顶点
rectangular [rekˈtæŋɡjələ(r)]，rect：adj. 矩形的，成直角的

Parameters
box - The input rotated rectangle. It may be the output of
points - The output array of four vertices of rectangles. 矩形 4 个顶点组成的列表。
