Abstract: | System calibration,which usually involves complicated and time-consuming procedures,is crucial for any three-dimensional(3D) shape measurement system based on vision.A novel improved method is proposed for accurate calibration of such a measurement system.The system accuracy is improved with considering the nonlinear measurement error created by the difference between the system model and real measurement environment.We use Levenberg-Marquardt optimization algorithm to compensate the error and get a good re... |
