- Abstract:
-
Real-time detection of carrier aircraft pose is of great significance to the movement control, trajectory planning, and collision avoidance of carrier-based aircraft on deck. The traditional scheduling of carrier aircraft mainly relies on the manual judgment of the position and heading angle of the carrier-based aircraft. Traditional methods fail to obtain accurate data and readily cause collisions because of operator negligence and fatigue. Therefore, a real-time visual measurement algorithm for the pose of carrier aircraft is proposed. First, the carrier aircraft is identified and segmented based on the you only look once version 4 (YOLO-V4) network and the Canny edge extraction algorithm. Then, an innovative algorithm for wireframe template matching is proposed, and the best pose is obtained by calculating the matching degree between the contour of the carrier aircraft and the wireframe template. The algorithm meets the real-time requirements through parallelization and graphics processing unit acceleration, and the test is completed in the 1:70 and 1:14 physical simulation environments. The results show that the recognition rate of this algorithm is >95%, the accuracy is within 0.7° and 8 mm, and the speed can reach 8 Hz.
