Non-contact Human Body Measuring Technology Based on Camera Calibration Technique

Abstract

The basic theory of camera calibration is firstly introduced in this paper. The model of camera distortion\r is put forward. And discussed the parameters and the calibration process of the mathematical model of\r 3D human body reconstruction. In the process of camera calibration, an improved algorithm based on\r the two steps is proposed. This method has low requirements on experimental. This method has low\r requirement to experiment, and only with coplanar points to calibrate. By the process of fractional step\r calibration, the nonlinear equation is linear, which is beneficial to improve the calibration accuracy.
