返回Opencv-Python教程 因为绘图操作需要用到起点、终点坐标等参数,绘图前需要先了解在OpenCV中图像像素位置的坐标表示方法。一般我们用的直角坐标系x轴向右增长,y轴向上增长,但是在OpenCV图像中,y却是向下增长的,也就说一张图片左上角顶点的坐标为(0,0),这样的处理也符合人类从左到右、从上到下的阅读习惯。

OpenCV是旨在解决计算机视觉问题的Python绑定库。 cv2.circle()方法用于在任何图像上绘制圆。 语法: cv2.circle(图像, 中心坐标, 半径, 颜色, 厚度) 参数: 图像:这是要在其上绘制圆的图像。 中心坐标:是圆的中心坐标。坐标表示为两个值的元组, 即(X坐标值, Y坐标值)。

OpenCV-Python 是一个 Python 绑定库,旨在解决计算机视觉问题。 cv2.circle() 方法用于在任何图像上画一个圆。 语法:cv2.circle(image, center_coordinates, radius, color, thickness) 参数: image:要画圆的图像。 center_coordinates:圆的中心坐标。坐标表示为两个值的元组,即(X 坐标值,Y 坐标值)。 radius:...
The problem is that opencv needs the center point to be a tuple of the X and Y coordinates and the coordinates individually have to be integers and not floats. I would suggest wrapping your center parenthesis and your individual coordinates with int(). Like this: a = cv2.circle(frame, (...
