摘要
农村宅基地面积测量工作一直存在难度大、时期长、效率慢等问题。鉴于此,首先利用激光雷达扫描技术采集农村宅基地目标点云数据,并对点云数据进行滤波去噪和配准,提取点云数据特征,识别宅基地目标,划分界址点;然后结合界址点和网格面积、数量,计算农村宅基地面积。结果表明,根据农村宅基地面积精度要求,计算得到的农村宅基地面积限差和中误差均在要求范围内,说明激光雷达扫描技术在农村宅基地面积测量中具有很好的应用效果。
There are some difficulties in the measurement of rural homestead such as long period,low effciency,etc.Therefore,we used LiDAR scanning technology to collect the point cloud data of rural homestead targets,filtered,denoised and registered the point cloud data to extract the cloud data characteristics of rural homestead sites,identified homestead targets,and divided boundary sites.Then,combining with the boundary point,grid area and quantity,we calculated the rural homestead area.The result shows that according to the accuracy requirements of rural home-stead area,the tolerance and mean square error of calculated rural homestead area are within the accuracy requirements,indicating that LiDAR scanning technology has a good application effect in rural homestead area measurement.
