hi, I'm working for my final year project which required to measure height of human and length of arm using single still image capture on raspberry pi camera with known reference distance from the camera to the subject and also known height distance of the camera from the floor.
Problem rising right now is how to set the pixelpermetrix ratio. should i use a known size object and use it as a reference point?
how to contour a body precisely? how to measure human height and length of arms only?
