摘要
大型储油罐检测,受地形及周围环境复杂、罐体较大、储油罐之间间距较小等因素的影响,致使常规检测方法困难重重。文中采用地面三维激光扫描仪通过对储油罐的无接触、高速率扫描,既解决了现场复杂的难题,提高了检测效率,又保证了检测精度。通过实例点云数据处理,提取所需数据,进行精度分析,验证了地面三维激光扫描技术在工程结构物检测领域高效快速的优势。
The conventional methods had many difficulties in detection of large oil tanks affecting by terrain,complicated environment,larger tank,small pitch between tanks.In the paper,three dimensional laser scanner adopted noncontact,efficient scanning mode solving the complex problem,improving efficiency and ensuring the detection precision.Fast and efficient advantages of terrestrial 3D laser scanning technology were verified by processing point cloud data,extracting the required data and analyzing precision in engineering structure detection.
