在海港航道、内河航道和港池的水深勘测中,测深仪是不可缺少的设备。尽管目前已引进自动定位勘测系统,但目前国内所使用的测深系统有些产品还是需要人工定标,为提高两定位点间的插点精度和工作效率,我们设计了自动定标器。在四波道测深仪 In the seaport waterway, inland waterway and port basin water depth survey, the depth sounder is indispensable equipment. Although automatic positioning and surveying system has been introduced at present, some products of sounding system currently used in China still need to be manually calibrated. In order to improve the precision and working efficiency of the interpolation point between the two locating points, we designed an automatic calibrator. In the four-channel depth sounder
