License plate recognition equipment for vehicle loading

Abstract

The invention relates to the technical field of license plate recognition equipment, in particular to license plate recognition equipment for vehicle loading, which can automatically and synchronously adjust the height, the pitching angle and the transverse shooting angle of a camera, enlarge the shooting range of the camera, enable the camera to carry out 360-degree dead-corner-free shooting, reduce the occurrence of shooting omission and improve the shooting efficiency. The reliability of the device is improved; comprising a fixed bottom plate, a rotating plate, a supporting plate, a plurality of sets of supporting columns, a stud, a first-stage pipe, a second-stage pipe, a third-stage pipe, a first threaded sleeve, a connecting annular plate, an outer threaded pipe, two sets of connecting sliding columns, a second threaded sleeve, a camera, a power assembly, a rotating assembly and a pitching adjusting assembly. The supporting plate is fixedly installed on the upper end face of the rotating plate through multiple sets of supporting columns, the first-stage pipe is fixedly installed on the upper end face of the supporting plate, the second-stage pipe is sleeved with the first-stage pipe in a sliding mode, the third-stage pipe is sleeved with the second-stage pipe in a sliding mode, and the camera is connected with the upper end face of the third-stage pipe through the pitching adjusting assembly.

Description

technical field [0001] The invention relates to the technical field of license plate recognition equipment, in particular to a license plate recognition device for vehicle loading. Background technique [0002] License plate recognition refers to the ability to extract and recognize moving vehicle license plates from complex backgrounds, and to recognize vehicle plate numbers, colors, and other information through license plate extraction, image preprocessing, feature extraction, license plate character recognition, and other technologies. Vehicles can be divided into heavy and light according to the weight and volume of the vehicle. Due to the different sizes of the loaded vehicles, the installation height of the license plate will be different when the vehicle is installed. However, the existing license plate recognition equipment usually The camera is installed at a fixed angle position, so during its use, it is often easy to cause the license plate information not to be ...

[0002] License plate recognition refers to the ability to extract and recognize moving vehicle license plates from complex backgrounds, and to recognize vehicle plate numbers, colors, and other information through license plate extraction, image preprocessing, feature extraction, license plate character recognition, and other technologies. Vehicles can be divided into heavy and light according to the weight and volume of the vehicle. Due to the different sizes of the loaded vehicles, the installation height of the license plate will be different when the vehicle is installed. However, the existing license plate recognition equipment usually The camera is installed at a fixed angle position, so during use, it is often easy to cause the license plate information to not be recognized, so that there is a dead angle when the device is shooting, resulting in missed shots.
