【Abstract】 In this paper, laser scanning system at home and abroad from the research experience, the 3D laser scanner hardware and software to achieve the key technology in-depth study and discussion. And software modules designed a detailed introduction.In this paper, mainly concentrated in the following areas:(1) In this paper, the existing three-dimensional methods to obtain information and summed up the classification, these methods of the strengths and shortcomings, pointing out that the current urgent need to resolve this area of the hot issues and research.(2) 3-D laser scanner scans the overall design programmes including hardware design, software design, hardware design approach focuses on a sophisticated data collection system and development programme.(3) 3-D laser scanner data acquisition system for the programme. On the principle of access to data from the method. In summing up the work on the basis of their predecessors, from the point of view, the three-dimensional access to information systems sources of error, error causes and transmission carried out a detailed analysis. Encoder to the point of the measurement data access, data and distance from the perspective of data integration, synchronization match.(4) scanners and computer data communication protocol in the study, three-dimensional scan data communication methods and software design and implementation, computer control of data communication channels.The large number of different target groups through the scanning experiment to verify the accuracy and effectiveness of the system. To the development of real-time 3D scanning systems, multi-directional scanning system, and other follow-up system of ideas and technical ideas. This paper summarizes the main findings of the study, by the need to address the issue of the follow-up studies were discussed.更多还原
