In the long-endurance UAVs, the conventional INS/GNSS integrated navigation system is widespread used. But with the increasing man-made interference and electromagnetic environment worsening, the GNSS system will be easily failing in location. In that case, using other aided navigation systems based on the characteristics of objects & geophysical field is necessary. However, the aided navigation...
To improve comprehensive performance of denoising range images, an impulsive noise (IN) denoising method with variable windows is proposed in this paper. Founded on several discriminant criteria, the principles of dropout IN detection and outlier IN detection are provided. Subsequently, a nearest non-IN neighbors searching process and an Index Distance Weighted Mean filter is combined for IN denoising...
