Global Registration Program Based on Targets

Point cloud registration is one of the core technologies of the three-dimensional laser scanning technology. Because of the limitations of the existing registration methods, the paper presents a registration program, which is the global registration based on targets. Compared with other registration methods, it improves the field efficiency and reduces the burden of field and human, has not error accumulation problem of continuous registration too. Certainly its accuracy is moderate. All of those bring convenience to the data processing. The results are the basic data of 3D model construction, which provides a three-dimensional model for digital city or smart city by GIS (Geographic Information System).
