基于倾斜摄影与地面激光扫描的三维建模技术

3D Modeling Technology Based on Tilt Photography and Ground Laser Scanning

静态三维激光扫描技术是先进的建模技术,其采用点云数据进行建模,具有较高的精确度,整个建模细节较完整。因此,要将倾斜摄影和地面三维激光扫描点云数据相互结合,通过多角度影像纹理自动映射技术,自动生产完整的三维模型,选择合适的检核点,对比实际测量结果。试验结果显示,采用倾斜摄影和地面三维激光扫描点云数据相结合的技术进行建模后,模型精度高于标准值,细部结构进一步完善,改善了模型应用效果。

Static 3D laser scanning technology is the most advanced modern modeling technology,which uses point cloud data for modeling with high accuracy and more complete details of the entire modeling process.Therefore,it is necessary to combine oblique photography with ground 3D laser scanning point cloud data,and use multi-angle image texture automatic mapping technology to automatically produce a complete 3D model,select appropriate verification points,and compare actual measurement results.The experimental results show that after using a combination of oblique photography and ground 3D laser scanning point cloud data for modeling,the model accuracy is higher than the standard value,and the detailed structure is further improved,comprehensively improving the application effect of the model.
