Moving target detection algorithm based on gyroscope correction under moving platform

Moving target detection is always a hot research field, which is widely used in many fields, especially in military field. In this paper, we use the gyroscope data to quickly screen the moving objects under the motion camera. Firstly, the feature points are extracted according to the curvature feature of the point target. Then, the camera is calibrated to obtain the external and internal parameters of the camera, and the gyroscope error is corrected according to the original dense background track recorded by fitting the gyroscope data, and the obtained correction value is compensated back to the original image coordinates of the feature points, to obtain the corresponding world coordinates. Then the point correlation of the feature points in the world coordinate system is carried out to form a stable track. Finally, according to the motion characteristics of the feature points, the moving target trajectory is selected to realize the detection of the moving target under the motion camera. According to the experiments in this paper, the feasibility and high efficiency of the gyroscope modified screening target in the world coordinate system can be proved.
