Abstract

The invention discloses a multi-target vehicle tracking method based on a Markov decision process (MDP), and the method comprises the steps: obtaining a target vehicle through a video sequence, detecting the target vehicle, and enabling the target vehicle to enter an activated state; wherein the state of the target vehicle comprises an activated state, a tracking state, a non-activated state and alost state; for the target vehicle in the activated state, training a binary classifier in an offline mode, and judging the state transition of the target vehicle according to the binary classifier;for the target vehicle entering the tracking state, an appearance template is constructed for the target vehicle in an online mode, and state transition of the target vehicle is judged according to the appearance template; for a target vehicle in a lost state, judgment of state transition of the target vehicle is realized through data association binary classifier reinforcement learning; the method can overcome the main technical difficulties faced by the vehicle tracking technology, reduce the tracking error probability and improve the tracking effect.

Description

technical field [0001] The invention relates to the technical field of target tracking, in particular to an MDP-based multi-target vehicle tracking method. Background technique [0002] According to the characteristics of the input video sequence when the target tracking algorithm is running, the input data can be divided into fixed camera shooting data and moving camera shooting data. For the data captured by a fixed camera, the background of the shooting scene is almost unchanged because the shooting point is fixed, and the most obvious change in the entire input data is the target to be tracked, so this type of data has lower requirements on the algorithm. As for the data captured by the motion camera, because the shooting point is moving all the time, this causes the entire shooting picture to be in constant motion, which poses a great challenge to the correct operation of the tracking algorithm. At the same time, environmental factors will pose more challenges to vehic...
