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...
opencv rect 扩大 opencv rectangle参数 相关函数介绍 Point 该数据结构表示了由其图像坐标 和 指定的2D点。可定义为: Point pt; pt.x = 10; pt.y = 8; 或者 Point pt = Point(10, 8); Scalar 表示了具有4个元素的数组。次类型在OpenCV中被大量用于传递像素值。
