摘　　要：飞机外形的控制是建立在精确测量的基础上。国内目前飞机外形检测主要依靠卡板等工艺装备,在测量准确度和效率上都无法满足现代飞机测量要求。采用一种利用激光雷达,在CATIA中进行测量路径规划和检测结果仿真,与激光雷达通信完成测量的方法,实现了飞机外形现场自动化测量。为了在保证测量精度的前提下,能够以最短的路径安全而又高效地遍历待测对象的检测区域,研究了自由曲面的测点规划布置的算法原理,在此基础上提出了矩形合并测量路径规划方法,可以有效地指导飞机外形现场数字化测量。运用提出的矩形合并测量路径规划方法,对中机翼段模型进行仿真分析取得了良好的效果,为飞机外形数字化检测提供了有效方法。The control of the aircraft shape is based on accurate measurement. The board is mainly used for aircraft shape measure- ment at. present at home. Its measuring accuracy and efficiency are unable to meet the requirements of modem aircraft measure- ment. In this paper, a metrology approach which is used to plan and simulate the measuring path in CATIA. and the laser radar are used to realize the aircraft shape automatic measurement on the scene. In order to get the shortest, safe and efficient measuring path under the accuracy of measurement, a rectangle-combined method for measuring path planning is proposed based on the the- ory of measuring plan of free surface. To demonstrate our methods, a middle wing model is simulated. A reliable method is given to the aircraft shape digital detection.
