| 摘要近些年，随着经济的稳步增长，科学技术也在不断的发展着，很多科学领域迎来了发展的高峰，比如计算机、人工智能与自动化控制，这也使无人车的研究成为热点。无人车是一种复杂的智能系统，它具有感知环境、理解环境、决策路径、自动控制等诸多特点。无人车研究的基础是进行周围环境中障碍物的检测和识别，这也是该研究中最有影响力的部分，因为要想实现无人车的安全行驶，就必须保证无人车能准确知晓障碍物的信息。25510 确定障碍物需要使用传感器作为工具，目前有多种传感器可供选择，其中单线激光雷达凭借其工作频率高，数据精度高，价格合理等诸多优点，被广泛的应用在无人车的研究中。本文研究的内容是利用三个单线激光雷达，对小车周围进行360°全方位无死角的扫描，通过分析扫描数据，确定车身周围障碍物的信息。 关键词 无人车 激光雷达 障碍物检测 毕业论文设计说明书外文摘要 Title 360 degree obstacle detection based on 3 single track radar Abstract In recent years, with the steady growth in the economy, science and technology also in the unceasing development, many fields of science ushered in the peak of the development, such as computers, artificial intelligence and automation control, which also makes unmanned vehicle research has become a hot spot. The unmanned vehicle is a kind of complex intelligent system, which has many features such as perception environment, understanding environment, decision-making route, automatic control and so on.. Research on unmanned vehicle is the basis of the detection and identification of the obstacles in the surrounding environment, which is the study of one of the most influential part of the, because to achieve unmanned vehicle safety driving, it is necessary to ensure unmanned vehicle can accurately know the obstacle information. Identify obstacles to using the sensor as a tool, there are a variety of sensors are available, which single line laser radar with its high working frequency, high precision data, reasonable price, and many other advantages, is widely application in the research of unmanned vehicle. In this paper, the content of the three single track laser radar, around the car around the no dead angle scanning, through the analysis of scan data, to determine the body around the obstacle information.
