Abstract
A vehicle recognition method includes: acquiring a training set including multiple vehicle images which includes vehicles at a designated crossroad and corresponding vehicle information; performing learning and sampling by a neural network to obtain a subnetwork model and determining same as a current model, and training the current model by using the training set to obtain reward parameters; calculating a constraint condition value of the current model, calculating a reward value on the basis of the constraint condition value and the reward parameters, updating trainable parameters of the neural network by using the reward value, and returning to execute the operation of obtaining the subnetwork model until a preset condition is reached; after the preset condition is reached, selecting an optimal network model; and inputting a vehicle picture to be recognized into the optimal network model, to obtain vehicle information of the vehicle picture to be recognized.
