分析了大型高功率激光装置在线可替换单元装校过程的特殊性,建立了基于区域划分的下装系统的方向包围盒,在包围盒的计算中引入闵可夫斯基和的概念,并在其基础上对分离轴的选择进行优化组合,结合碰撞的局部性原理,构建了一种动态的OBB(Oriented Bounding Box)层次树检测方法,经过中国大型高功率激光装置下装系统的装校仿真实践,结果表明这种划分区域的连续检测方法高效可靠。
The particularity of the assembly and rectification processing of line-replaceable unit(LRU) in large-scale superpower laser facility is analyzed.Oriented bounding box(OBB) of down-load system,which is based on space region partition,is set up,and Minkowski sum is introduced into OBB calculation.Then the separating axis theorem is optimized,and a dynamic OBB hierarchy tree detecting method is created by combining locality principle of collision.The results from the assembly and rectification practice in a large-scale superpower laser facility confirm that the method is highly efficient and reliable.
