汽车驾驶员前方视野测试系统的设计与研究

The Design and Research on motor vehicle forward visibility for drivers

文章通过对汽车驾驶员前方视野测试方法相关标准的研究分析,介绍一套基于VB平台开发的汽车驾驶员前方视野测试系统。该系统首先利用具有定位功能的专用装置快速地估计出挡风玻璃或A柱上符合标准要求的点和线的大概区域,然后通过数据接口文件实现计算机与三坐标测量仪间的实时通讯,将获取的三坐标当前测量点的数据代入各测试项目的数学计算模型,并依据标准限值对其进行符合性判定。

This paper introduced a driver's forward vision field measurement system developed basing on VB platformthrough the research and analysis of the driver's forward vision field test methods and related standards.Firstly the systemestimate the point and line’s general area on the windshield or the A-Pillar that meet the standards’s requirements.Then itachieved the real time communication between the computer and the three coordinate measuring instrument through the datainterface file,then it put the achieved current three coordinate measuring instrument data into each test items’mathematicalmodels and do the conformity determination according to the standards’limite value.
