摘要
ADS100作为徕卡公司最新一代数字航空摄影测量系统,现已成功应用于实际生产项目中。本文采用近红外波段辅助空三加密连接点提取,优化同名像点的匹配结果。并结合Leica XPro软件,与传统可见光空三加密精度进行对比分析。实验结果表明,采用近红外波段辅助空三连接点的提取,可以匹配更多的同名像点,改善空三加密的精度,更好地满足航测大比例尺的生产需要。
As Leica’s latest generation of digital aerial photogrammetry system, ADS100 has been successfully applied to practical projects. Based on the NIR, this paper has achieved the aerial triangulation and optimized the result of the corresponding points matching, and discussed the precision of aerial triangulation based on the NIR and the visible light with the Leica XPro software. The result showed that the number of corresponding image points based on NIR would be more than that based on visible light, and the accuracy of aerial triangulation based on NIR would be higher. It could better meet the requirement of large scale topographical map.
