基于主客观组合赋权评价技术的雷视一体机安装方案优选

Optimization of installation scheme of the sensing device combining radar and camera based on evaluation method combining subjective and objective weights

对雷视一体机安装位置、旋转角度等进行试验分析,基于主客观组合赋权评价方法提出一种较优的解决方案。在设计安装方案之前,分析影响安装方案的主要因素并作为单一变量设计5组工况;根据搭建的雷视一体机平台进行数据采集分析,选取9个指标构建评价体系;提出基于方差最大化主客观组合赋权法和基于熵权逼近理想解排序法对各安装方案进行综合评分和优选。选取2个实地场景进行试验验证,结果表明,提出的评价技术可成功地优选安装方案,但根据不同的安装场景,如车道宽度、安装高度等,安装优选方案会有所调整。本研究能够实现雷视一体机在道路上的布设优化,具有一定推广应用价值。

This paper analyzed the factors in terms of spatial location and rotation angles,and proposed a better solution based on evaluation technology of assignment method combining subjective and objective weights.Before designing the installation scheme,five main factors were designed as control variables in the controlled experiment.Data were collected by the platform of the sensing device combining radar and camera.The content of data was analyzed,nine parameters were selected to construct the evaluation sys-tem and two evaluation techniques,evaluation method combining subjective and objective weights based on the variance maximiza-tion and evaluation method combining entropy weight and TOPSIS method,were proposed to score each installation scheme compre-hensively and to prefer the installation scheme.Two scenarios were selected for experimental validation,and the results showed that the proposed evaluation method optimized installation schemes.But the optional installation scheme would be adjusted depending on the environment such as lane width.This method could realize the optimization of installation scheme of the sensing device combi-ning radar and camera,which had the value of popularization and application.
