The invention discloses a vehicle information detecting and recognizing
system under the multilane condition. The vehicle information detecting and recognizing
system comprises a computer
system and a
portal frame stretching over lanes, wherein a
laser scanner and a high-definition
license plate recognition device are arranged on the
portal frame, a first
dot matrix type wheel shaft sensor, a shaft weight sensor and a second
dot matrix type wheel shaft sensor are sequentially arranged on the lane under the
portal frame, and the
laser scanner, the high-definition
license plate recognition device, the first
dot matrix type wheel shaft sensor, the shaft weight sensor and the second dot
matrix type wheel shaft sensor are respectively connected with the computer system. The vehicle information detecting and recognizing system has the advantages that the two-dimension cross section size and the running position of a vehicle are detected through the
laser scanner, and the vehicle three-dimension reconstitution and the vehicle separation are realized; the
license plate information and the human face information are precisely collected through the license plate recognition device; the vehicle information such as the shaft distance, the
shaft length, the shaft number, the shaft type, the wheel distance, the wheel width and the wheel number are measured according to signals output after a vehicle tyre presses the wheel shaft sensor; and the shaft weight and the total weight are measured through the shaft weight sensor.
