飞机装配中激光雷达测量场布局规划方法探讨

Discussion on Layout Planning Method of Laser Radar Measurement Field in Aircraft Assembly

激光雷达可以较为精确地测出物体空间轮廓,在飞机制造业中具有重要作用。激光雷达因对光路可达性、光路距离、光路入射角等参数有要求,其位置摆放必须满足一定条件。首先建立了激光雷达布局规划的几何约束要求,分析了碰撞干涉的实现方法;基于空间圆锥曲面和曲线,研究了激光雷达的可放置区域的表示方法和规划方法。最后为了满足工程可实现性,基于网格法反向推导了激光雷达布局规格的点位。所实现的布局规划方法对激光测量设备的位置规划具有一定的指导意义。

Laser radar can accurately measure the spatial contour of objects,which plays an important role in aircraft manufacturing.Due to the requirements of laser path accessibility,optical path distance,optical path incident angle and other parameters,the location of lidar must meet certain conditions.In this paper,firstly,the geometric constraint requirements of laser radar layout planning are established,and the realization method of collision interference is analyzed.Then,based on the spatial conic surface and curve,the representation method and planning method of the placement area of lidar are researched.Finally,in order to meet the engineering feasibility,the points of the layout specification of laser radar are deduced based on the grid method.The layout planning method implemented in this paper has a certain guiding significance for the location planning of laser radar measurement equipment.
