To research and develop a new laser scanning 3-dimensional digitization system for collecting, showing, and measuring the data of dental casts.
According to the 3-dimensional measuring method, by using 2 pulsate motors to make the synthetic movement of the dental cast, a special semiconductor laser, and 2 special line array CCD, the 3-D data could be found anywhere on the surface of the dental cast. The program, developed with Visual C++ language under the Windows (Windows tm) system, can control the scanner, rebuild the 3-D graphics and measure the data of the dental cast.
The system offers 70 x 70 x 70 mm measurement scope, 0.01 mm resoling power, < 0.1 mm mean deviation, and 25 mins for single cast scanning.
The advantages of this system are its precision, simplicity, high efficiency, and wide range of measurements with complete direct view. This system also supplied new information that cannot be found with traditional measurement methods.
研究并开发一种新的激光扫描三维数字化系统，用于收集、显示和测量牙模数据。
根据三维测量方法，通过使用2个脉冲电机使牙模进行合成运动，采用一种特殊的半导体激光器和2个特殊的线阵电荷耦合器件（CCD），可在牙模表面的任何位置获取三维数据。在Windows（Windows tm）系统下用Visual C++语言开发的程序，能够控制扫描仪、重建三维图形并测量牙模数据。
该系统的测量范围为70×70×70毫米，分辨率为0.01毫米，平均偏差<0.1毫米，单次牙模扫描时间为25分钟。
该系统的优点是精度高、操作简单、效率高、测量范围广且具有完整的直观视图。该系统还提供了传统测量方法无法获得的新信息。
