| 摘 要： | 单波束测深仪是现代海洋和内河水下地形测量中使用最为频繁的测量仪器。硬件设备固有特性和水下复杂的特殊环境,易导致单波束测深仪在实际使用中产生各类型的粗差。单波束采集时按照每条测线进行处理,在数据处理上往往存在不同船只、不同测线难以一体化处理的问题。文中针对水深值粗差的特点,设计了单波束数据采集和处理一体化方法,在区域处理单波束数据的基础上,提出一种顾及地形的单波束水深测量数据多测线粗差检测方法,并针对上海周边实测区域对单波束测深数据采集和处理进行全方位的验证,结果表明应用本方法不但提升了数据精度和数据处理可靠性,而且大幅提高了作业效率。

| Abstract: | The single beam bathymetry is the most frequently used type of measuring instrument in modern marine and inland water topographic surveys. The intrinsic characteristics of the hardware device and the special environment under the water are easy to cause the single beam bathymetry to produce various types of gross errors in actual use. Since single-beam acquisition is processed according to each line, there are often problems in the later data processing that are difficult to integrate with different ships and different lines. In this paper, based on the characteristics of water depth difference, a single beam data acquisition and processing integration method is designed. Based on the regional processing of single beam data, a single beam water depth measurement data multi-line gross error detection method is proposed. The data collection and processing of single beam sounding is verified in all aspects of the measured area around Shanghai. The results show that the application of this method not only improves the data accuracy and data processing reliability, but also greatly improves the work efficiency. |
