Claim 1:
2. The method according to claim 1, wherein before the inputting road information contained in each sequence in the at least one sequence into a pre-trained neural network model to obtain a recognition result of a corresponding sequence, the method further comprises:
acquiring a sample set, wherein samples in the sample set comprise positive samples and negative samples, the positive samples are real road information, and the negative samples are false road information;
dividing the samples in the sample set to obtain at least one sample sequence, wherein samples belonging to the same sample sequence in the at least one sample sequence have the same type and occurrence location; and
training an initial model according to the at least one sample sequence to obtain the neural network model.
