My project is about image detection. I am using 1 camera and have 2 shapes (rectangle and triangle) placed on a flat surface. I have successfully been able to:
- Detect the contours
- Detect the area of the contours
- Make a relation between both areas and the distances, to be able to calculate both distances from the camera
- Calculate the lengths, corner coordinates and the angle of each corner in both shapes
Now I need to calculate the angle of rotation of the whole surface when rotated around the x-axis (up & down), y-axis (left & right) and both axes (oblique). This can be seen in the gif I provided. The default angle (0 degrees) is when the surface is parallel to the camera, and any rotation would mean that an angle around 1 or both axes is present.
P.S When the surface is rotating around both axes (oblique), both angles have to be detected separately. For example, I would get 14° x-axis & 27° y-axis.
Any help would be appreciated.
