I have 2 concentric circles with known radiuses and sector start and end points of each circle($A, B, C, D$ and $O$ in figure is known) . I detected the circles from image. I have 2 points on the inside circle and 2 points on the outside circle. I want to find all points between these 4 points inside circular ring.
If we draw a tangent to the midpoint of given 2 points(A and B) in the outer circle and form a line then find 2 points meet the lines OB and OA. If we join inner circle points we get a line. Then we have to check each point inside this trapezoid and check whether the point is inside the sector. But I don't know how to do it mathematically in an optimized way. Any help would be highly appreciated.
