基于势能场的大尺寸测量中仪器位置的可行域求解方法

Novel Approach to Solving Feasible Domain of Large-scale Measurement Instruments Based on Potential Rnergy Field

提出了基于势能场的大尺寸测量中仪器位置的可行域求解方法。首先构建综合障碍物距离、障碍物主表面积及仪器视角的势能函数,从而得到有关仪器位置的虚拟势能分布。通过合理选择势能阈值,可获得测量仪器的可行域。以某飞机舱门检验型架的测量场景为例,验证了方法的可行性和有效性。

A method to solve the feasible domain of large-scale measurement instrument based on potential energy field was presented. A potential energy function which includes obstacle distance, obstacle superficial area and visual angle of measurement instrument is established. The virtual potential energy distribution can be got. With a reasonable potential energy threshold, the feasible region of measurement instrument can be obtained. A calibration example about aircraft door inspection fixture shows that the proposed method is effective and feasible.
