是一个 Python 绑定库,旨在解决计算机视觉问题。cv2.rectangle() 语法:cv2 .矩形(图像、起点、终点、颜色、厚度) 参数:图像:就是要画矩形的图像。起点:是矩形的起始坐标。坐标表示为两个值的元组(即X坐标值、坐标值)。是矩形的结束坐标。坐标表示为两个值的元组(即坐标值)。

python cv2.rectangle error: TypeError: function takes exactly 4 arguments (2 given) 无力吐槽下 opencv 关于 ptyhon cv2.rectangle 出现的 “TypeError: function takes exactly 4 arguments (2 given)” 错误 当我看到这个错误的时候,我一直核对我的参数数量是否正确,但是找来找去就是有4个变量,还想是不是op...
Draw a rotated box in openCV in python I would like to draw a rotated rectangle I've got the top left point and bottom right point, width and height of box. As well as the angle. But I can't seem work out how you draw the rotated rectangle......
A rectangle is defined by its start position (x, y) and size (width, height). One example of usage is in creating a view on an image, a rectangle defines the view region inside the image. Parameters x (int)– The x-coordinate position of the rectangle. y (int)– The y-coordinate...
