The 3-D Laser scanning technology is a rising surveying and mapping technology, and will be the technological revolutions in the surveying and mapping field next to the GPS technology. The 3-D Laser scanner is already the important development directions of the instruments of surveying and mapping. A method to totalize the 3-D Laser scanner is mainly researched in this paper to improve the existing scanner's performance and expand its applied range. A platform coordinate is imported into the scanner, and the totalizing technique of the scanner is represented based on the research of the coordinate transform and the scanner's orientation. The orientation marker and the orientation arithmetic are designed according to the characteristics of the scanning data. An angle-info acquisition system is designed and realized to get the real-time angle using a raster disc as the sensor. A software platform for the processing of the scanning data is developed using the OSG convient for the application of the scanning data. The application of 3D Laser scanning technology in heavy and high-temperature forgings dimensional metrology is researched to improve the measurement of the internal forging, and the experiment is made in the forging workshop using the commercial scanner that is made in China.
