Three-dimensional Measurement System Design Based On Single-chip Optical Sensor Technology And Realization

Three-dimensional measuring system is one hardware requirement in Digital Photogramm-etry workstation, it is controlled by manipulator under tridimensional observation and inputs the digital displacement into computer to collect the information of terrain and to complete tridimensional measuring. In this paper, the current three-dimensional measuring systems in home and outsides are analysed, the design project based on optic induction technology and singlechip is put forward. In the case, the problem in orientation is solved by optic induction technology, the system is composed of integrate circuits, in the end the integration is enhanced and the design of hardware is simplified. The data collection process and communication in the system are completed by programming. The system meet the demand for miniaturization and integration of the system and meet the demand of the special measuring in the mutual experiment, the foundation is laid for the manufacture of three-dimensional measuring system in digital photogrammetry independently.
