| Abstract: | In order to realize accurate measurement of aircraft's current attitude,how to improve real time and robustness of star pattern recognition is the key of star sensor.The algorithms for star pattern abstraction,training sample set creation and network training improvement are proposed.First,a method of triangulation based on the character of star image is designed to combine all the stars of current field of view,which is used to extract star pattern and create complete training samples.The character of star... |
