Research and simulation of laser positioning technology for ships

现有的测绘船舶上使用的传统激光定位是通过激光光敏硬件与定位算法相结合的方式,来完成对测绘目标的定位操作。在使用过程中,激光定位目标经常出现定位点精度偏差,导致后续图像测绘精度降低的问题。通过对问题的分析,提出测绘船舶的激光定位技术研究与仿真。首先,对传统激光光敏发生硬件参数进行模型构建,通过模型,得到激光发生过程中的误差参量;然后,引入激光高精度定位算法,对误差量进行修正计算,完成高精度激光定位计算;最后,通过仿真实验的方式,对提出的设计方案进行实验性论证,证明其有效性。

The traditional laser positioning used in surveying and mapping ships is to complete the positioning operation of Surveying and mapping targets by combining laser photosensitive hardware with positioning algorithm.In the process of using laser positioning target,the positioning accuracy deviation often occurs,which leads to the problem of reducing the accuracy of subsequent image mapping.Through the analysis of the problems,the research and Simulation of laser positioning technology for surveying and mapping ships are put forward.Firstly,the hardware parameters of traditional laser photosensitive generation are modeled,and the error parameters in the process of laser generation are obtained through the model.Then,the high-precision laser positioning algorithm is introduced to correct the error and complete the high-precision laser positioning calculation.Finally,the experimental demonstration of the proposed design scheme is carried out by means of simulation experiments to prove its effectiveness.
