This paper mainly focuses on the integration of 3D reconstruction systems from single encoded images based on the multicolor code of pseudo-random arrays and the flexible precalibration and 3D recohstruction technology. With a LCD projector the parameters of which need to be pre-calibrated and a CCD camera the parameters of which are allowed to change with the varying scene, an encoded image is preprocessed first, and then the characteristic points are detected and matched. Based on the hierarchical 3D Euclidean reconstruction theory, the 3D data of the image can be recovered and the 3D shape of the scene reconstructed. The experiment shows that the integration of 3D reconstruction system has good reliability.
