摘要

智能手机边框在制造过程中往往存在形变问题，先前的视觉定位方法难以得到精确的边框点胶位置。针对此问题，提出了一种新颖的手机点胶三维轨迹生成方法。首先，使用三维线激光测量仪扫描边框，引入基于位姿图的点云拼接算法解决边框点云的拼接问题。采用基于模板的方法，标注模板点胶轨迹。然后，通过基于变形图的非刚性配准算法将模板与目标边框对齐，得到变换后的轨迹，并提出轨迹优化策略生成精准的目标点胶轨迹。实验证明，所提方法生成的轨迹精度可达0.01 mm以下，且速度可达到在线实时测量效果。

Abstract

Due to the potential issue of non-rigid deformations in the manufacturing process of mobile phone frames

most existing dispensing automation methods struggled to acquire accurate dispensing positions. For this purpose

an innovative approach of dispensing trajectory generation was proposed

which addressed the limitations associated with previous methods. Firstly

the phone frames were scanned using a 3D laser profiler

then a point cloud registration algorithm based on the pose graph was introduced to reconstruct the point clouds of frames. The template-based approach was employed

and the dispensing trajectory for template was manually annotated. Subsequently

the template was aligned with the target by a non-rigid registration algorithm based on the deformation graph

thereby the transformed trajectory was obtained. Furthermore

a trajectory refinement strategy was presented to generate the robust

accurate dispensing trajectory of the target. Extensive experiments demonstrate that the errors of the generated dispensing trajectories were consistently below 0.01 mm

and the speed can meet the real-time requirement of practical applications.
