基于侧扫声纳的船舶吨位测量技术研究及应用

Investigation and application of ship tonnage measurement technique using side-scan sonar

在自动化测量技术迅速发展的今天,国内外对船舶吨位的测定却主要依据船舶图纸及证件,存在着诸多弊端。为解决上述问题,本文在对侧扫声纳成像原理分析后,认为侧扫声纳对水面目标同样可以成像,设计了利用侧扫声纳测量内河航道过闸船舶实载总吨位的测量方案。为了对测量方案进行验证,本文使用Starfish 450F型侧扫声纳于常州魏村船闸开展实地测量实验,所得理论计算结果与实际丈量结果误差较小,证明了本文提出的船舶吨位测量技术的可行性,对船舶吨位自动化测量的实现具有一定的价值。

Nowadays, the automatic measurement technology is still determined by the drawings and documents which may is rapidly developing while the ship tonnage has many drawbacks. In order to solve this problem, it is feasible to use side-scan sonar to take images of targets on water surface based on the sonar＇s working principle. In this paper, side-scan sonar is used to scan and measure the actual total shipping tonnage of the ships passing inland waterway lock. For verification, a field measurement experiment have been done by using Starfish 450F in Wei village lock Changzhou. The errors between theoretical results and actually measured results are small, which proved the measurement technology is feasible to achieve ship tonnage automatic measurement.
