Multifunction dual lens matching device for stereoscopic 3D camera system
This invention is for target remapping, telecentricity compensation, and a new PID motion control algorithm to align and control to a very high tolerance multiple functions to two lenses simultaneously in a stereoscopic 3D camera system. To control two lenses in a 3D camera rig such that they match as closely as possible in “actual” positions, a new error variable is calculated, based on the difference between the “actual” positions of both lenses. This is added to the PID formula, as a new statement, with a new coefficient, which we call the PID3D algorithm.
