Optimization of Projection Matrix between Cameras Based on Levenberg-marquardt Algorithm ?

The calibration of projection matrix between cameras and the optimization of the projection matrix based on Levenberg-Marquardt algorithm will be introduced in this article. The optimized parameters of projection matrix can be obtained by the least squares principle and the parameters are the iterative initial values of Levenberg-Marquardt (called L-M for short) to implement the second optimization of projection matrix parameters. This method will further improve the accuracy of measurement system. The results of simulation and experimentation demonstrate that measurement system based on the principle of least squares to obtain the initial optimization parameters and using the L-M algorithm to second times optimization has a higher precision, it is well suited for high accuracy measurement.
