Abstract:
To verify the influence of optical axis pointing error on optical pose measurement accuracy and provide a theoretical basis for subsequent real-time equipment to realize pose measurement, through splitting the algorithm steps and tracing the influence of the optical axis pointing error based on the central axis method, a conclusion is drawn that the pointing error can affect the pose processing results, which is divided into two parts. The direct influence of the model intersection algorithm and the indirect influence of the dynamic benchmark outside the model are deduced and analyzed, through the combination of simulation calculation and measured data, the conclusion that pose angle error is no more than 0.1° in typical medium and long-term optical pose measurement in the situation 200" pointing error of is obtained.through the combination of simulation calculation and measured data, the conclusion that pose angle error is no more than 0.1° in typical medium and long-term optical pose measurement in the situation 200" pointing error of is obtained. It lays a theoretical foundation for the capacity expansion of subsequent range equipment.
