hi I want to convert the detected face rectangle (the original face detection sample)into a 3D coordinates . I have the intrinsic parameters of my camera, how can I determine the depth Z? using the projection equation? how can i get the face depth ?
x = fx X / Z + u
y = fy Y / Z + v
I understand that fx fy and u v are intrinsic parameters, x y are given by the detected face rectangle.what does the X,Y represents?
Basically you did not listen to me in previous posts. In order to define depth from a 2D image, you need to use the idea of stereo vision which gives you the projection matrix. There is no simple formula to deform your rectangle into a 3D location based on a single bounding box...
