Optimization of Dynamic Obstacle Avoidance Path of Multirotor UAV Based on Ant Colony Algorithm

Abstract: In this paper, the real-time path avoidance problem of multirotor UAV in the case of sudden obstacles in two-dimensional environment is studied. The principle, model, and application of ant colony algorithm are analyzed. On this basis, the adaptive dynamic window ant colony algorithm is proposed, and the adaptive dynamic window method is designed; the heuristic function of adding obstacle detection factors and the double pheromone update strategy are made to the ant colony algorithm, and the improved ant colon… Show more

“…Through this, the depth camera acquires the depth image, and the left and right infrared cameras measure the depth [9][10][11][12]. The middle infrared dot matrix projector is equivalent to a fill light, and the RGB camera on the right is used to collect color pictures, which can align the color video stream with the depth stream [13].…”

“…If the environmental information that needs to be collected is relatively complex, the time for establishing this map is quite long. Efficiently generating robot motion environment maps has become an urgent problem to be solved [38,39]. a real environment map by taking photos, process the real environment map, transform non-standard environment maps into robot path planning maps suitable for robot path planning, and then carry out path planning and pose planning for robots, this can greatly improve the efficiency of robot path planning.…”

“…Compared with traditional graph search algorithms, swarm intelligence algorithms can handle incomplete information in complex environments, easily ensure path continuity, and are more suitable for path planning in 3D space. Common swarm intelligence algorithms include the ant colony algorithm [ 17 ], particle swarm optimization algorithm [ 18 ], and artificial bee colony algorithm [ 19 ]. Although these swarm intelligence algorithms can be used to generate the flight path of plant protection UAVs in 3D space, they have many disadvantages, such as uncertain convergence speed and long planning time, and they are not suitable for application scenarios with high real-time requirements.…”
