Abstract:Multi-vehicle information fusion technology in ground unmanned systems is an important way to
improve system environment perception. Aiming at the problem of discontinuous and unstable object tracking caused
by vision occlusion and blind spots in single-vehicle sensors,a result-level fusion system model for centralized multi-
vehicle cooperative perception is proposed. The system model uses lidar as the vehicle perception sensor,and uses
D-S evidence theory to fuse the environment grid maps constructed by different vehicles at main control terminal to
obtain a global static environment map,completing the construction of the multi-vehicle cooperative perception
environment model. On the basis of this environment model,a multi-vehicle cooperative object detection and tracking
method is designed. First,the maximum value suppression method is used to resolve the detection object fusion
conflict; then a cascaded dynamic object matching and tracking management method is designed to complete object
prediction and tracking and send the results to each test results of a real-vehicle system composed of two
unmanned vehicles show that when the object is occ
