The feasibility study of wavelength selection of multi-spectral LIDAR for autonomous driving

In the autonomous driving system of automobile,in order to improve the performance of sin‐ gle-wavelength LIDAR in physical property detection classification and state,and draw lessons from the principle that multi-spectral detection has physical property detection ability,this paper studies the band selection of multi-spectral LIDAR,calculates and analyses the spectrum of typical targets in au‐ tonomous driving by using principal component analysis method. The characteristics of laser source and detector,the band selection method of multi-spectral LIDAR,the spectral characteristic analysis of typical targets for autonomous driving application scenarios and the availability of commercial LI‐ DAR are synthesized. The central wavelength of the multi-spectral LIDAR suitable for autonomous driving of automobiles is 808 nm,905 nm,1 064 nm and 1 310 nm. The validity of the selected wave‐ length of the multi-spectral LIDAR is verified by testing. 文章编号:1001-9014(2020)01-0086-06 DOI:10. 11972/j. issn. 1001-9014. 2020. 01. 012 收稿日期:2019⁃ 08⁃ 22,修回日期:2019-11-21 Received date:2019⁃ 08⁃ 22,Revised date:2019-11-21 基金项目:上海第二工业大学校重点学科建设项目(XXKZD1605);校企合作汽车电子联合实验中心建设项目资助(A11NH190704) Foundation items:Supported by Discipline Construction Project of Shanghai Polytechnic University(XXKZD1605),and Construction Project of Uni⁃ versity Enterprise Joint Automobile Electronic Experiment Center(A11NH190704). 作者简介(Biography):宋绍京(1974-),男,山东泰安人,副教授,主要从事图像处理与分析、实时信号与信息处理、智能驾驶等方面研究,Email:sjsong@sspu. edu. cn *通讯作者(Corresponding author):E-mail:sjsong@sspu. edu. cn 1期 宋绍京 等:适用汽车智能驾驶的多光谱激光雷达波长选择可行性研究
