摘要
通过研究目标镜面反射造成的测距误差,及分析强度数据与测距误差之间的关系,建立了一种基于原始强度数据的目标镜面反射测距误差模型。研究结果表明,利用原始强度数据可以建立一种测距误差修正模型,该模型不受目标材质和表面几何形状的影响,可以精确地对距离数据进行修正,对提高地面激光雷达的数据精度具有重要意义。
By exploring the range errors from the target specular reflection, and analyzing the relationship between range errors and intensity data, a range error model from the target specular reflection based on original intensity data is established. Experimental results show that the original intensity data can be used to establish a range error correction model, which is independent of target material and surface geometry. According to the original intensity, the distance data can be accurately corrected, which is of great significance to improve the accuracy and quality of terrestrial laser scanning.
