7.a. Straight Bounding Rectangle. It is a straight rectangle, it doesn't consider the rotation of the object. So area of the bounding rectangle won't be minimum. It is found by the function cv.boundingRect().

At last we find a minimum enclosing circle for every polygon and save it to center and radius vectors. The following are 30 code examples for showing how to use cv2.FILLED().These examples are extracted from open source projects. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example.

函数 cv2.minAreaRect () 返回一个Box2D结构 rect:(最小外接矩形的中心(x,y),(宽度,高度),旋转角度)。. 分别对应于返回值: (rect [0] [0], rect [0] [1]), (rect [1] [0], rect [1] [1]), rect [2] 借用原博主的图片(侵即删):. 注意 :旋转角度θ是水平轴(x轴)逆时针旋转,与碰到的矩形的第一条边的夹角。. 并且这个边的边长是width,另一条边边长是height。. I'm trying to extract the rotated bounding box of contours robustly.

Return Value Type: RotatedRect [Missing documentation for "M:OpenCvSharp.Cv2.MinAreaRect(OpenCvSharp.InputArray)"] draws a rectangle around that area using cv2.minAreaRect The idea was that cv2.minAreaRect returns the angle as well, which I could use to deskew the image. However, in my case it's –90°. You can see a sample input image here. In the above code, we first find the rectangle enclosing the text area based on the four points we provide using the cv2.minAreaRect () method.

You can see a sample input image here. In the above code, we first find the rectangle enclosing the text area based on the four points we provide using the cv2.minAreaRect () method. Then in function crop_rect (), we calculate a rotation matrix and rotate the original image around the rectangle center to straighten the rotated rectangle. Extent is the ratio of contour area to bounding rectangle area.
