Paper Abstract

In the field of vision measuring, camera calibration is a necessary precondition of the three-dimensional measurements. For the sake of obtaining high-precision external parameters, the inadequacies which cycling conditions restrict external parameters calculation in traditional calibration method was founded and elaborated in detail. The re-projection error was re-selected as cycling conditions and a new amended method was designed to solve the above shortcomings. Then Binocular vision system calibration experiments was carried , it has been found that standard deviation and the maximum error of three-dimensional reconstruction target after the amendments for external parameters is less than the calibration errors before the amendments.
