Wheel pose measurement based on cross structure light

摘要: It's necessary for automobile to detect and adjust four-wheel alignment parameters regularly, due the significant effect on improving stability, enhancing security reducing tire wear of automobiles. In order measure that determined by relative position posture four wheels cab, this paper proposes a method which applies monocular vision linear structure light wheel pose measurement. Firstly, space coordinates feature point cloud are calculated out from principle structured light. Then, an algorithm is designed determine normal vector tangent plane pose. Finally, actual experiments evaluation adjusted angle measurement carried verify system accuracy. The corresponding studies can be applied in designing developing 3D based
