摘要
激光雷达拥有众多优良特性,被广泛应用于探测障碍物和感知环境。而由于水环境的复杂性,激光雷达在水环境下测量精度不高,应用也较少。本文基于激光对不同材料的反射特性,提出了一种在水环境下提高激光雷达精度的方法。该方法利用激光的反射特性,通过人工智能判别选择激光雷达的最佳工作角度区域,从而在水环境下提高了激光雷达的测量精度。在船舶干舷高度测量系统的实际应用中,验证了该方法的可行性,提高了船舶干舷高度测量的可靠性。
Lidar has many excellent features and is widely used to detect obstacles and the perception of the environment.Due to the complexity of the water environment,the Lidar has low measurement accuracy and less application in the water environment.Based on the reflection characteristics of lasers on different materials,this paper proposes a method to improve the accuracy of Lidar in water environment.The method utilizes the reflection characteristics of the laser to determine the optimal working angle region of the Lidar through artificial intelligence,thereby improving the measurement accuracy of the Lidar in the water environment.In the practical application of the ship's freeboard height measurement system,the feasibility of the method was verified and the reliability of the ship's freeboard height measurement was improved.
