Description

Technical Field

[0001] The present invention relates to the technical field of camera devices, and in particular to a camera device for intelligent recognition of motor vehicle license plates. Background Art

[0002] License plate recognition cameras convert optical image signals into electrical signals for storage or transmission. License plate recognition cameras have added license plate recognition functions. The light reflected from the license plate is collected by the camera lens and focused on the light-receiving surface of the camera device, such as the target surface of the camera tube. The camera device then converts the light into electrical energy, that is, a "video signal" is obtained, and then the corresponding license plate number is obtained through license plate recognition algorithm analysis.

[0003] At present, the number of cars on the road is increasing, and the number of violations during driving is also gradually increasing. In order to better supervise driving violations, electronic eyes are set up in areas with large traffic volume and frequent accidents to take photos of vehicle violations and identify the vehicles in the photos. However, due to various reasons, the electronic eyes malfunction, resulting in many violations that cannot be photographed and punished in time. At the same time, in some temporary venues for activities, it is necessary to identify the license plates of vehicles entering or passing. At this time, the installation process of the electronic eyes is relatively complicated and cannot be effectively used. It is now urgently needed to design a portable and quickly installed motor vehicle license plate intelligent recognition camera.

[0004] The Chinese invention patent with the publication number CN110111583A discloses a portable license plate recognition device, which belongs to the field of autonomous driving. A portable license plate recognition device includes a top cover and a device housing, and also includes a fixing device; a mainboard is fixedly installed inside the recognition housing, and a lighting lamp fixedly installed on the mainboard can provide lighting for the vehicle, so that the camera can be used normally at night. When necessary, the lighting lamp can also flash at a certain frequency. Since there are certain blind spots in license plate recognition during normal use, it is sometimes necessary to adjust the direction of vehicle recognition. The setting of the fixing device can drive the overall rotation of the device housing, and the inertial rotating blades are fixedly installed inside the connecting pipe. When the vehicle is in an accelerated state, the inertial rotating blades rotate to dissipate the heat inside the device housing. This device realizes the recognition of license plates, but this device cannot replace the work of electronic police. At the same time, when used instead of electronic police, it is impossible to adjust the appropriate angle to shoot illegal behaviors on different lanes. At the same time, this device is not convenient to carry. Summary of the invention
