在传统飞机部件位姿拟合算法基础上,提出了被测点的误差评估方法。通过对某机型中机身壁板进行型面测量,将测量数据与被测数模进行对比分析,引入变形权重因子,对传统的SVD算法进行优化,形成基于变形补偿的位姿拟合优化算法。以中机身侧壁板为实例,进行装配应用验证。 Based on the fitting algorithm of pose of traditional aircraft parts, the error assessment method of the measured point is proposed. Through measuring the profile of fuselage panel in a certain type of aircraft, the measured data are compared with the measured digital model, and the deformation weight factor is introduced to optimize the traditional SVD algorithm to form a posture-fitting optimization based on deformation compensation algorithm. Take the side wall in the fuselage as an example, the assembly application verification.
