Abstract
A method of tracking multi-obstacle objects in the field environment, a system, a device and a medium thereof are provided. The method includes using a Kalman filter to obtain prediction box center pixel coordinates and BEV object prediction center coordinates and using IMU data information to correct the prediction box center pixel coordinates. Obstacle object recognition is performed on an RGB image. Point cloud center coordinates are determined from the bird's eye view. The IMU data information is used to correct the point cloud center coordinates and an OCSORT model carries out minimum cost matching to obtain primary matching information. If detection boxes are matched with prediction boxes, the primary matching information is taken as successful matching information of the current frame, otherwise, an LAPJV algorithm is used to carry out minimum cost matching based on depth point cloud information to obtain the successful matching information of the current frame.
