Design and Key Technology of Coordinate Detection System for Burst Point of Artillery Shells Based on Rotor UAV

The coordinate detection of the burst point of artillery shells is the main basis for shooting deviation correction and the core link to the damage effected evaluation. The accuracy and real-time performance of the burst point of artillery shells has always been a major and difficult issue in the military field at home and abroad. At present, most of the coordinate detection of the burst point of artillery shells is based on ground observations, which has limitations on visibility. The observing field is small, and it is prone to occlusion. At the same time, due to the different requirements and understanding of the detection of the coordinate detection of the burst point of artillery shells, the detection output is different, such as the output of the burst point of artillery shells contour and detection frame, image coordinates of the burst point of artillery shells, and the three-dimensional coordinate of the burst point of artillery shells based on a fixed reference point. Based on this, our paper designs an intelligent coordinate detection system for burst point of artillery shells based on rotor UAV. Through the image segmentation technology, the contour of the burst point of artillery shells is segmented, and then the image coordinates are calculated. Combined with the photogrammetry model and the digital elevation model, the geodetic coordinates are calculated.
