摘要
对于当前已有的系统或方法,由于探测精度还有一定提升空间,因此通过应用激光差频扫描技术的应用提升水下三维探测系统的探测精度。在系统的设计中,主要设计了3个模块,其中激光差频扫描模块主要通过激光差频扫描系统进行被测点及其周围区域的随机三维扫描探测。补偿校正模块可以对船速延时效应和波浪带来的测深值误差实施综合补偿校正。数据处理模块负责对系统采集的三维探测图像进行处理。将设计系统搭载在一艘无人船上,进行系统的探测精度测试与分析。精度分析结果表明设计系统的探测精度很高,有很强的实用性,可以应用于复杂情况下的水下探测。
Due to the existing system or method,the detection accuracy still has some room to be improved,so the application of laser differential frequency scanning technology can improve the detection accuracy of the underwater three-dimensional detection system.In the design of the system,three modules are mainly designed.The laser difference frequency scanning module mainly uses the laser difference frequency scanning system to perform random three-dimensional scanning detection of the measured point and its surrounding area.The compensation correction module can implement comprehensive compensation correction for the ship speed delay effect and the sounding value error caused by waves.The data processing module is responsible for processing the three-dimensional detection images collected by the system.The design system is mounted on an unmanned ship,and the detection accuracy of the system is tested and analyzed.Accuracy analysis results show that the detection accuracy of the designed system is very high,has strong practicability,and can be applied to underwater detection in complex situations.
