Algorithm Design for Intelligent Draft Survey System
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.
