- Abstract:
-
To enhance the search efficiency of the ant colony algorithm for unknown targets in a large-scale grid environment, an active perception search framework based on the ant colony algorithm is proposed. In this framework, the unmanned aerial vehicle (UAV) motion mode was selected using the historical environment information. The new environment information was obtained from the motion mode and sensing domain information of the UAV to enhance the intelligent automatic search function of the UAV group. The new algorithm calculates an unsearched probability with exploration preference to carry out a UAV search with a bias towards the grid with the highest unsearched degree, which improves the algorithm’s searchability. Additionally, based on the unsearched probability and pheromone, a new motion mode selection mechanism was developed. This mechanism considers the possible known and unknown target regions for searching targets with no prior information. The simulation results showed that this algorithm has higher search efficiency and more comprehensive target distribution information than the existing algorithms used in large-scale grid environments.
