地面激光扫描强度数据的影响因素分析
Review on Influencing Factors of Terrestrial Laser Scanning Intensity Data
摘要
Abstract
Terrestrial laser scanner provides both the geometry information and the intensity data of scanned objects. The intensity data can be used to discriminate different materials, since it contains physical and chemical proper-ties of scanned objects. In addition to the reflectance of the target at the wavelength of the laser, the intensity data is influenced by many other factors. Firstly, the influencing factors were summarized in four aspects, such as in-strument mechanism, environmental condition, object surface properties and scanning geometry. Then, the effects of four factors on intensity date were summed up and analyzed. Finally, that the influences of instrument mecha-nism, distance and incidence angle should be considered in the application of intensity data was pointed out.关键词
