摘要: 目前激光打标中存在的一个问题是将图案映射到物体表面上往往会发生不同程度的变形，对此本文提出了一种图案映射方法。本文针对三维网格模型与平面图案，首先建立网格曲面与平面之间的映射关系，将曲面展平为二维平面，然后将平面图案与展平的平面对齐，进而建立平面图案与打标曲面之间的映射关系。通过计算机仿真验证该映射算法能有效减小激光打标中图案的变形。
Abstract: A challenging topic of laser marking is to mark any 2D-complex pattern onto sculpture surfaces with shape preserving property, so this paper aims to provide a solution which realizes marking 2D patterns onto sculpture surfaces. A general idea of the solution is as follows: based on the data description of the 2D pattern and the sculpture surfaces presented in facet model, first flattening the facet sculpture surfaces into an abstract 2D region, then mapping the 2D pattern onto the 2D region. From the corresponding 3D line patterns on the sculpture surface, we can build tool paths to accomplish the marking of the target line patterns on the sculpture surfaces. In addition, it is verified by computer simulation that the mapping method can reduce the pattern deformation in the laser marking effectively.
