A Simple Image Acquisition System and Its Calibration for Image-Based 3D Reconstruction

This paper presents a simple image acquisition system composed of multiple cameras and a turntable, through which object's multiple-view images can be acquired and calibrated automatically. The main contribution of this paper is proposing a calibration algorithm for this system which using a simple calibration equipment to calibrate the cameras' intrinsic and their extrinsic relate to the center of turntable, and with these system parameters, all the acquired multi-view images can be easily calibrated. Combined with MVS, mesh generation and texture mapping algorithms, complete texture model can be automatically reconstructed from the calibrated images. The calibration and reconstruction examples based on the system are given in the end of the paper. The experimental results show the presented system with our calibration algorithm has high reconstruction accuracy, and can be used for many reconstruction applications.
