Abstract

The aircraft flight attitude can be obtained by the dynamic visual measurement system for aircraft (hereinafter short for MSA). It is crucial for MSA to evaluate its flight attitude measurement accuracy. There are several indoor evaluation methods for the MSA’s attitude measurement accuracy which is not suitable outdoors. Therefore, we present a method for evaluating its flight attitude measurement accuracy at outdoor working site. A three-dimensional standard verification field can be established by reasonable distribution of mark targets on the surface of outdoor building group. We construct a verification system for flight attitude measurement accuracy at outdoor working site. The building group whose threedimension scale is similar to the aircraft’s three-dimension scale is selected to construct the standard verification field. Paste mark points on the surface of the building group and their coordinates in 3D space are measured by the threedimensional coordinate measuring station consisting of two electronic theodolites. Mark points with known coordinates construct the standard verification field. Still photographs of the standard verification field are taken by the MSA. the attitude solved from the still photographs is used as reference attitude. Manipulate the MSA to shoot and record dynamically to simulate the real working condition, and photographs are taken to solve the dynamic measurement attitude at the same time. Accuracy analysis and evaluation can be performed using the dynamic measurement attitude and the reference attitude to provide scientific basis for debugging, checking outdoor parameters and acceptance of equipment.
