The accuracy of star centroid extraction and identified star number is both crucial features for star sensor precision. Motion blur and fracture are introduced when star sensor works under high dynamic conditions, which affect the accuracy of star centroid extraction and further reduce the precision of the star sensor. To improve the precision of star sensor, this paper proposes a star image restoration...
In order to alleviate the model-mismatching and improve tracking precision of high speed strong maneuvering targets in near space, a new strong tracking filter algorithm with improved jerk model is proposed. The improved jerk model, in which the acceleration is assumed to be an exponential-correlated random process with non-zero mean, is used in the paper. Moreover, a fading factor is introduced in...
Intelligent transportation systems (ITS) are the mainstream of the development of next-generation technologies. The project of Human-centered technology (HT)-ITS in Taiwan has launched R&D researches in driver assistance and safety warning systems. This paper demonstrates a part result that a multi-sensors integrated system to achieve the purpose of the vehicle navigation and safety warning assistance...
