It is known that the robots fitted with cameras, also sometimes called as unmanned aerial vehicles, are used to monitor inaccessible areas. The data sent by robots are analyzed through various artificial neural networks. Active vision is particularly important to cope with problems like occlusions, limited field of view, and limited resolution of the camera. In view of the active vision difficulty faced in active perception system, this paper proposes an active perception framework of heterogeneous robots based on the self-organizing feature map, a type of multi-objective active learning algorithm, and plans the shortest smooth path for the drone team to traverse all the targets. First, the multi-target active perception scene is modeled as multiple traveling salesmen problem with neighborhood. After that, the self-organizing mapping network is used to find the shortest closed-loop track for travel time, and then the track is smoothed with the third-order Bézier curve, a parametric curve. The simulation results and comparative experiments show that proposed method has better effects in the application of multi-objective active perception.
