摘要: 為了獲取模擬月面的三維地形數(shù)據(jù)，采用激光雷達系統(tǒng)進行專項試驗場地形測量。文章分析了激光雷達系統(tǒng)的測量站點布局規(guī)劃和位置參數(shù)設(shè)置對大尺寸地形掃描測量的影響，重點研究了激光雷達在景深條件限制下為實現(xiàn)最大掃描面積的有效掃描高度和掃描寬度設(shè)置。研究結(jié)果可為深空大范圍掃描測量深入研究提供一定的參考。Abstract: In order to acquire the three-dimension topographical data of the simulated lunar surface, a laser radar system is used to measure the topography of the experimental area. To accomplish the large-size topography scanning, the layout of the laser radar’s measurement sites and the setting of laser radar’s location parameters are determined, focusing on the effective scan height and width of the laser radar for maximizing the scanning area within the limit of the depth of the field.
