摘要
激光雷达技术作为现代测绘领域的重要技术手段,在高精度地形测量中展现出显著优势。通过分析激光雷达技术原理及其在复杂地形环境下的应用特点,结合具体工程项目实践,验证了该技术在提高测量精度、扩大作业范围、降低作业难度等方面的有效性。实践表明,激光雷达技术能够获得厘米级测量精度,作业效率比传统测量方法提高3~5倍,在山区、林地等复杂地形环境下表现尤为突出,为现代地形测量提供了可靠的技术保障。
Light Detection and Ranging(LiDAR)technology has become a cornerstone of modern surveying,offering significant advantages for high-precision topographic measurement.This paper analyzes the operational principles of LiDAR and its application characteristics in complex terrain environments.Validation through practical engineering projects confirms its effectiveness in enhancing measurement accuracy,expanding operational coverage,and reducing fieldwork complexity.Practical applications demonstrate that LiDAR achieves centimeter-level measurement precision,with operational efficiency 3 to 5 times higher than traditional surveying methods.Its performance is particularly outstanding in challenging environments such as mountainous and densely forested areas,establishing it as a reliable technological foundation for modern topographic surveying.
