姿态修正技术在黄河河口测验中的应用

为了解决黄河三角洲附近海区测验中测船姿态对单波束数字测深数据的影响，本文利用姿态传感器对测船的姿态进行了有效改正。试验结果表明，姿态修正技术对数字测深仪瞬时水深进行改正后，其测深结果与传统的人工水深曲线改正后成果比较，中误差为0.089 m，试验段面0 m线以下面积相差不超过0.22%，符合国家规范要求，提高了海区测验中测深成果的精度，为数字技术在海区测量的应用提供了技术保证。

Application of attitude correction technology in the Yellow River estuary test

In order to solve the effect of the ship survey attitude on the single beam digital sounding data in the sea area test near the Yellow River Delta, the attitude sensor is used to effectively correct the ship survey attitude. We draw a conclusion by comparing the test data: the result of the posture correction technology correcting the instantaneous water depth of the digital sounder is compared with the result of the traditional artificial water depth curve, the median error is 0.089 m, and the difference between the areas below the 0 m line of the test section does not exceed 0.22%. The result meets the requirements of national regulations. This paper improves the accuracy of the sounding results in the sea area test and provides a technical guarantee for the application of digital technology in sea area measurement.
