摘要
由于船舶位置模糊,导致传统的船舶自动避礁行驶路径识别方法存在误差大、效率低的问题,为此提出基于移动定位技术的船舶自动避礁行驶路径精确识别方法。利用投影变换原理生成并显示船舶行驶环境电子海图,并分析在礁石环境中,船舶自动避礁的行驶方式。利用移动定位技术,实时采集船舶的行驶位置信息,并在电子海图中显示定位结果。最终通过路径生成和地图匹配2个步骤,得出最终的船舶自动避礁行驶路径识别结果。实验结果表明:设计方法的识别误差仅为1.67 km,平均时间开销为2.18 s,即具有较高的运行效率。
Due to the fuzzy position of the ship,As a result,the traditional route recognition methods for ships to avoid reefs have the problems of big error and low efficiency.The principle of projection forward transformation is used to generate and display the electronic chart of the ship’s driving environment,and the driving mode of the ship’s automatic avoiding reef in the reef environment is analyzed.Using mobile positioning technology,real-time acquisition of the ship’s position information,and display the positioning results in the electronic chart.Finally,through the two steps of path generation and map matching,the final result of automatic reef avoidance path recognition is obtained.The experimental results show that the recognition error of the design method is only 1.67 km,and the average time cost is 2.18 s,which means it has high efficiency.
