摘要
针对现有船舶水尺计重过程中存在的主观因素和数据同步性等问题,本研究利用雷达测量技术,通过激光测距仪准确定位,结合三角高程测量法,计算吃水深度.将以上长时间、多点同时测量得到的数字信号用事先预设的算法自动筛选出数据集,计算出结果并形成直观图像.与人工方法比较前后尺总体差异小于 0.1%,提高了水尺计重测量的准确性和科学性,有较大的推广应用前景.
Abstract
In view of the subjective factors and data synchronization in the process of draft survey of existing ships,this study uses radar measurement technology,accurate positioning by laser rangefinder,and triangulation elevation measurement method to calculate the draft.The digital signals obtained from long-term,multi-point simultaneous measurements are automatically filtered into a dataset using a pre-set algorithm.Subsequently,the results are calculated and visualized as an intuitive image.Compared with manual methods,the overall discrepancy of the two draft survey before and after is less than 0.1%,which enhances the accuracy and scientific reliability of draft surveys,presenting significant potential for widespread adoption.
