No more accurate method was found. opencv included an elliptical image, and its center position was pixel-level. How can we achieve sub-pixel accuracy? The following uses the method of drawing a small circle to draw a point. The coordinate of a point is the center of the circle. Given a smaller radius, the point can be represented by this small circle. Circle function: void cvCircle( CvArr* img, CvPoint center, int radius, CvScalar color, int thickness=1, int line_type=8, int shift=0 ); Example

a point to a circle If the point is at the center of the center, undefined is returned.The connection point P and the center O. If the Po is parallel to the X axis, the abscissa of the closest point is centerpoint Based on P on the left or right of O. x-radius or centerpoint. X + radius, as shown in 4 (a). If the Po is parallel to the Y axis, the ordinate of the closest point is calculated as

. We had to re-plot it, but it was fast, so we thought of using the bitblt function.It supports the copying of graphic blocks at a fast speed. We can plot the graph in the memory first, then use this function to copy the graph to the foregroundDo not refresh the background. This eliminates flickering. The above is the basic idea of Double Buffer plotting. I. Common Methods: Program by using the common graph method. Add the drawing code to the ondraw function of the video class. Here we plot a n
