| 摘 要： | 机载LiDAR测深技术被认为是海洋测绘领域极具潜力的对地观测新技术,国内对LiDAR测深的试验大都是针对南海这类水质较清的区域。本研究首次在国内引入先进的CZMIL(Coastal Zone Mapping and Imaging LiDAR)系统,选取较为浑浊的江苏省骆马湖作为试验测区,进行了测深试验。试验结果表明,在测区有着低底部反射率、高漫衰减系数的情况下,CZMIL系统仍能够成功探测到湖底数据,成果精度达到了CZMIL系统标称的测深精度指标,具有较好测深探测能力和精度。

| Abstract: | Airborne LiDAR sounding technology is considered to be a promising new technique for earth observation. In China, most of the LiDAR sounding experiments were conducted in areas with relatively clear water quality, such as the South China Sea. This is the first time to introduce the advanced CZMIL(Coastal Zone Mapping and Imaging LiDAR) system in China. The Luoma Lake in Jiangsu Province was selected for experimental area. The test results show that although the survey area has low bottom reflectivity and high bottom reflection diffuse attenuation coefficient, CZMIL system can successfully detect the bottom data. The accuracy of result can meet the accuracy requirement of CZMIL system. The CZMIL system has better detection ability and precision. |
