摘要:
为了检测轿车后三角包边玻璃与标准样件之间的误差,提出包边玻璃点云参数化重构和拼接方法.根据后三角包边玻璃的测量要求,在获得其点云已消噪的情况下,应用B样条法构造出玻璃双二次加权曲面参数方程.根据过渡曲面一阶导数连续的性质,导出交于公共边界的控制网格矢量之间的关系,研究其不同分片曲面之间的光滑拼接方法,并举例验证方法的有效性.检测结果表明,重构曲面经过分层切片,可以用于检验与标准样件之间的误差,而且该算法运算量较少,精度可控制.
Abstract:
In order to obtain the tolerance between the wrapping-side rear triangular glass and the standard workpiece of car,a surface reconstruction and merging method for points cloud parameterizing of the glass was proposed.According to the measuring requirement of wrapping-side glass,the bi-quadratic parameter equation of glass was constructed by B-spline method on condition that the point cloud was obtained and was noise-ridding.The relations among the control grid vectors intersecting on the public boundaries were deduced on the basis of the continuousness of first derivative of transition surface.The smoothness merging method between different partial unit surfaces was studied,and the validity of this method was verified by an example.The detecting results show that the slicing reconstruction surface can be used for the comparison between the glass and the standard workpiece.The calculation of this algorithm is small,and the precision is controllable.
