摘要
地形测绘技术在地理信息系统及地形辅助导航中起着相当重要的作用,当前地形测绘技术已由过去的人工测绘发展为利用多种手段进行自动测绘。其中利用机载或星载激光雷达进行测绘是一种先进的测绘手段,目前在国际上已普遍采用。该方法与传统的人工测绘比较,具有全天候、精确性高、实时性强等诸多优点。主要介绍了利用机载激光雷达并结合全球卫星定位系统、惯性导航技术建立地形高程模型的一种新方法。该方法在带状地形的测量方面具有较好的精度和效果。
Terrain mapping technology plays a very important role in Geography Information System and Terrain aided navigation. Terrain mapping technology has developed from past manual mapping to automatic mapping by many means now. Especially terrain mapping by a airborne laser radar or a satellite laser radar is a very advanced technology. It has been popularly adopted internationally. Comparing with the traditional mapping technology, this technology is more precise and more real in time and it can work day and night, and so on. Briefly the paper introduces a new method to make a DEM by a airborne laser radar combining with Global Positioning System and Inertial navigation technology. In the band area, the method is more efficient and precise.
