摘要
Abstract
According to the high vegetation coverage of transmission lines in the mountainous areas of Northeast China and the fact that traditional optical measurement cannot obtain the true surface elevation,it proposes a field measurement technology that fuses airborne LiDAR and visible light images.It uses the fabric simulation filtering algorithm to remove vegetation interference,and uses the active penetration characteristics of laser pulses to reconstruct the digital elevation model.Taking a certain 220 kV transmission line as an example,it carries out verification through path optimization and line selection,precise control of earthwork and stonework,and automatic detection of tree obstacles in the channel.The results show that this technology improves the work efficiency by 84％compared with the traditional manual measurement.It controlls the error in the elevation measurement of forest areas within 0.15 meters,solving the problem of blind spots in the survey of complex terrains.关键词
