The embodiment of the invention relates to the technical field of video monitoring, and discloses an intelligent identification method and device for license plate numbers. The method is applied to ahigh-definition smart camera; the high-definition smart camera is connected with a laser ranging sensor; both the high-definition smart camera and the laser ranging sensor are arranged at a highway toll-gate; and the high-definition smart camera includes a common shooting mode, a high-definition shooting mode and a standby mode. The method comprises the following steps: receiving distance information of a driving car sensed in real time by the laser ranging sensor; enabling the common shooting mode according to the distance information; and when the distance information satisfies a preset condition, switching the common shooting mode to the high-definition shooting mode, so that the high-definition smart camera recognizes the license plate number of the car. Through adoption of the intelligent identification method and device, the burden of a system can be reduced; the service life is prolonged; and energy is saved.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of video surveillance, and in particular to an intelligent identification method and device for a license plate number. Background technique [0002] In recent years, video surveillance applications are in a stage of vigorous development, and the application of front-end equipment such as high-definition cameras is also expanding. In the context of anti-terrorism and stability maintenance and strengthening social security, license plate recognition technology has urgent needs in urban intelligent transportation, parking lot management, security checkpoints, expressway toll stations and other fields. [0003] At present, a large number of high-definition cameras are installed at expressway toll stations to capture the license plate numbers of passing vehicles. In order to obtain clear license plate number images, the high-definition cameras work in high-definition shooting mode 24 ho...
