【 摘 要 】

The coverage rate of wiped area is a critical index for designing the windshield wiper system and driver forward field of view in particular. SAE Recommended Practice clearly define the minimum requirements for wiped area that must be met before a passenger car can be sold. The challenge is to develop measurement methods which transfer wiper pattern extracted from the windshield glazing surface to the data that can be calculated. In this paper, we apply hand-held laser scanners to produce the point clouds of wiper pattern, convert them into computer-aided design model, and then trim areas A, B, and C according to the edge feature of wiper pattern, finally calculate the percentages of areas A, B, and C that are wiped. Compared with traditional photography-based measurement method, the application result showed that scanning-based method possess better accuracy performance for wiped area test.
