| 摘 要： | 水下地形测量质量检查主要通过布设一定数量的检查线，通过比对检查线和主测线相交处一定范围的测点水深差值来衡量，还需检查主测线长度、检查线长度、各深度区间中误差、不符值比例等参数信息。主测线数据和检查线数据量一般都比较大，单纯依靠人工对比计算难以高效、准确实现。目前Python语言以其简洁易用、可扩展行强的优点逐渐成为主流编程语言。PyQt5是Python中一个广泛使用的GUI工具包，可方便构建图形用户程序。本文针对水下地形测量质量检查检测数据量大、检查参数多的特点，利用Python语言，基于PyQt5设计开发了一套水深比对检测系统，在山东省水库水下地形测量质量检查中得到了实际应用，取得了较好的效果。

| Abstract: | The quality inspection of underwater terrain surveying mainly involves setting up a certain number of inspection lines, comparing the water depth difference of measurement points within a certain range at the intersection of the inspection line and the main survey line, and checking parameter information, such as the length of main survey line, the length of the inspection line, the error in each depth interval, and the ratio of discrepancies. The data volume of main survey line and the inspection line is generally large, and relying solely on manual comparison calculation is difficult to achieve efficient and accurate results. At present, Python language has gradually become the mainstream programming language due to its advantages of simplicity, ease of use, and strong scalability; PyQt5 is a widely used GUI toolkit in Python that facilitates the construction of graphical user programs. Poinying to the characteristics of large amount of data and multiple inspection parameters in underwater terrain measurement quality inspection, by using Python language based on PyQt5, a water depth comparison detection system has been designed and developed. It has been applied in the quality inspection of underwater terrain measurement in reservoirs in Shandong province and has achieved good results. |
