pt2是与pt1是相对的矩形顶点 @param color Rectangle color or brightness (grayscale image). 矩形的填充颜色或灰度值 @param thickness Thickness of lines that make up the rectangle. Negative values, like #FILLED (也就是 -1), mean that the function has to draw a filled rectangle. 构成矩形的线条...

在VC++中使用OpenCV绘制直线、矩形、圆和文字非常简单,分别使用OpenCV中的line、rectangle、circle、putText这四个函数即可。具体可以参考OpenCV官方文档:https://docs.opencv.org/4.x/index.html 下面的代码展示了在VC++中如何使用OpenCV绘制直线、矩形、圆和文字 ...
