Hello,
A Coordinate System is not actually functional in measurement applications.
When we define a coordinate system, it should set the x axis and the origin as 0,0 in mm or pixels depending on the calibration. Currently coordinate system is only working to define a ROI with changing positions. It always get the positions based on the camera's axis. But it also should work like a real coordinate system where you can get X,Y positions of a circle based on a defined coordinate system.
Currently, I am trying to create my own coordinate system by calculating angles, cosines etc. but this function needs to be implemented in standard coordinate system functions.
