Abstract


3D laser scanning technology is an emerging technology mapping , will be again after the technological revolution in the field of surveying and mapping GPS technology , 3D laser scanners has become an important direction for the development of surveying and mapping equipment . In order to improve the performance of the existing three-dimensional laser scanner , to expand the scope of its application , the paper focuses on the three - dimensional laser scanner station . Platform coordinate system is introduced in the scanner coordinate system by studying the conversion and the orientation of the scanner , the scanner station implementations ; designed according to the characteristics of the scan data , directional signs for the scanner to identify , design , and recognition algorithm ; grating dial to get the angle of rotation of the scanner , as the angle sensor , designed and implemented the the angle information collection system , real-time calculation and display of the angle of rotation of the dial . To facilitate the application of scan data , OSG development of scan data processing software platform . In order to improve the level of domestic forgings measurement , 3D laser scanner in the measurement of large - scale high-temperature forging the domestic commercial 3D laser scanner and do a measurement experiment in forging shop TM1600 .
