船舶吃水检测传统的方法采用人为测量船舷处的水尺,这种测量方法不仅受到海浪高低起伏的影响,导致观测结果误差大,观测人员还必须进行舷外作业,存在着作业风险。因此,提升船舶吃水线自动定位和检测技术有重要的应用前景。设计一种基于机器视觉技术的船舶吃水线自动定位系统,分别从吃水线自动定位系统的整体方案设计、硬件设计、软件环境、船舶吃水线图像的处理原理等方面进行研究,取得了较好的吃水线定位效果。
The traditional method of ship draft detection uses man-made measurement of the draft gauge on the ship's side. This measurement method is not only affected by the fluctuation of sea waves, resulting in large error of observation results. The observers must also carry out outboard operation, which has operation risk. Therefore, it has important application prospects to improve the automatic positioning and detection technology of ship waterline. In this paper, a ship waterline automatic positioning system based on machine vision technology is designed. The overall scheme design, hardware design, software environment and ship waterline image processing principle of the waterline automatic positioning system are studied in detail, and a better waterline positioning effect is obtained.
