The invention discloses vehicle identification method and system based on multilayer descriptors. The method comprises the following steps of: (1) extracting the global features of a vehicle; (2) extracting the singular area extraction features of the vehicle; (3) constructing the multilayer descriptors; (4) carrying out vehicle identification based on the multilayer descriptors, and acquiring the final vehicle identification result by virtue of various matching strategies, in case of comprehensively considering matching accuracy and matching speed. The invention develops a vehicle identification system based on multilayer features on the basis of the method; some specific vehicle identification systems are further invented on the infrastructure of the system. According to the vehicle identification method disclosed by the invention, the vehicle is described by the multilayer descriptors, and the matching accuracy and matching speed among the multilayer descriptors are ensured by the various matching strategies, thus the method is capable of obtaining good effects in vehicle identification applications in different fields.

The invention relates to a traffic flow statistics method in intelligent traffic. In the prior art, the accuracy of vehicle identification is insufficient, and the efficiency is not high. According tothe method, an SSD and a ResNet in a neural network are adopted, and the method is established with a traditional target tracking CamShift algorithm and comprises a vehicle detection method and a vehicle tracking method. According to the vehicle detection method, firstly, an SSD network is established, the SSD obtains a plurality of feature maps of different sizes, different aspect ratios are adopted for default frames on the same feature layer, the robustness of the default frames to the shape of an object is enhanced, and the position and the target type are regressed while the SSD trainingis carried out. According to the vehicle tracking method, a continuous self-adaptive expected movement algorithm is adopted to track a vehicle identified by a first frame of a single-time movement visual network detector. According to the method, the vehicles can be detected more accurately for statistics, the vehicles can be prevented from being lost through tracking to be counted again, and theobtained traffic flow data are more accurate.

The invention relates to an automatic barrier gate for the expressway entrance, which comprises a base, a bottom plate, a stop lever, a lifting mechanism and a card swiping mechanism, the lifting mechanism is arranged on a supporting rod, the card swiping mechanism is arranged below the bottom plate, and according to the automatic barrier gate for the expressway entrance, lifting of the stop leveris achieved through the lifting mechanism, and vehicle identification is achieved through the card swiping mechanism; compared with an existing barrier gate, the barrier gate drives the bottom plateto move through the gravity of passing vehicles, so that the stop lever is automatically lifted, electric drive is avoided, energy is saved, meanwhile, through linkage of the lifting mechanism and thecard swiping mechanism, lifting of the stop lever and simultaneous operation of the card swiping device are achieved, missed swiping is avoided, and a pure mechanical structure is adopted in linkage.use of sensors and other electronic elements is avoided, the stability of the device is improved, and the service life is prolonged, compared with an existing triggering assembly, the triggering assembly achieves a better clamping effect on the conductive column through the two triggering units, loosening of the conductive column and the electric sheet is avoided, and a better power-on effect isachieved.

The invention discloses a violation vehicle avoidance system based on a cloud server. The violation vehicle avoidance system comprises a cloud violation vehicle identification and management platform, a violation vehicle information database and a violation vehicle identification and avoidance system. The cloud violation vehicle identification and management platform obtains real-time regional road section traffic information and surrounding vehicle information uploaded by the violation vehicle identification and avoidance system, analyzes vehicle identity information according to the above information, judges the risk level of violation vehicles and possible violation behaviors by querying a violation vehicle information database, generates an avoidance strategy, and sends the avoidance strategy to the cloud terminal. The avoidance strategy is issued to the illegal vehicle identification and avoidance system for avoidance; the peccancy vehicle identification and avoidance system also feeds back the real-time avoidance effect to the cloud peccancy vehicle identification and management platform. The invention further provides a violation vehicle avoidance method based on the cloud server. The method is a forward management scheme, and can reduce the damage of traffic violation vehicles to driving vehicles.
