A cooperating camera calibration algorithm based on cameras with different precision is proposed.This algorithm consists of data preprocess procedure and cooperating calibration procedure.Binary search algorithm is used in the data preprocess procedure to find the incorrect feature point,In the cooperating callbration procedure,the camera with high precision will help the low one(low-cost) to eliminate error data.The camera in good spot will help that in bad spot to eliminate error data,and the error is ana...
