    摘要:

    地理測繪勘探激光雷達回波特征在山地區域應用,會(huì )出現光斑回波疊加,導致坐標混亂,特征監測效果差。本研究結合反射式激光雷達,在采集山地地理特征光斑數據的基礎上,優(yōu)化設計反射式激光雷達在山地地理測繪勘探中的應用過(guò)程,并確定其相關(guān)參數。通過(guò)分區對山地地理一一掃描,整合掃描結果,采集該山地地理特征的激光雷達回波數據。設計一種光斑回波波形分解模型,通過(guò)分解處理獲取地理特征,去除光斑回波疊加干擾,在通過(guò)坐標和高程轉換,解決坐標混亂問(wèn)題,完成特征的監控。實(shí)驗結果表明:該方法與傳統的方法比較,能夠更加有效監測出山地地理的變形量,監測效果好、監測性能較高。

    Abstract:

    The application of geographical mapping and exploration lidar echo features in mountainous areas will result in overlapping of spot echo, leading to coordinate confusion and poor feature monitoring effect. In this study, the application process of reflective lidar in mountain geographic mapping and exploration is optimized and its relevant parameters are determined based on the collection of mountain geographic feature spot data with reflective lidar. By scanning the mountain geography one by one and integrating the scanning results, the lidar echo data of the mountain geographical characteristics are collected. A decomposition model of light spot echo waveform is designed to obtain geographical features through decomposition processing, remove the overlapping interference of light spot echo, solve the problem of coordinate confusion through coordinate and elevation conversion, and complete feature monitoring. The experimental results show that compared with the traditional methods, this method can more effectively monitor the deformation of mountain geography, with good monitoring effect and high monitoring performance.
