Paper Abstract

The measurement of the wheel-aligning parameters is very important in the production of vehicles. In this paper, we present a non-contact measuring technique for the inspection of wheel-aligning quality in which the laser triangulation is employed based on structural light sensors. First, the main purpose of the inspection is introduced with corresponding parameters illustrated. Meanwhile, the main principles of the system and the structural light sensors are analyzed in detail. In the paper, the image processing techniques are studied, which include the noise eliminating algorithms and the symbol extraction methods. The image quality is effectively improved and the object points are successfully extracted by these methods. Moreover, the corresponding models are presented for the aligning parameters required. Using the techniques presented in the paper, an inspection system for the wheel-aligning parameters is fulfilled by which the automatic inspection is achieved.
