Problems solved by technology

The problem with this type of method is that, first, the time synchronization between the sensor and the video is prone to inconsistency between the alarm and the video due to time synchronization deviation; The traffic fee generated by real-time uploading is relatively high; third, ordinary high-definition cameras cannot clearly see the license plate information at night or when the light intensity is high, and a dedicated license plate camera must be used

Abstract

The invention provides a photographic device and method for license plates of moving vehicle. The photographic device comprises a multi-type sensor and a camera, wherein the camera is integrated with a preset port; and the multi-type sensor is connected with the camera through the port, collects an external sensing analog signal, and inputs the signal to the camera in real time. The camera comprises: a shooting module, which is used for shooting and storing real-time vehicle video information; a first processing module, which has at least one preset threshold value and is used for carrying out conversion processing on the sensing analog signal, judging whether the processed sensing analog signal reaches an alarm threshold value or not according to the preset threshold value, and generating a trigger instruction if the processed sensing analog signal reaches the alarm threshold value; and a license plate extraction module, which is used for extracting license plate information according to the trigger instruction. The multi-type sensor is connected through the preset port of the camera to complete recognition and acquisition of the license plate information in the vehicle video information in a target area, so the multi-type sensor and the license plate camera can be highly integrated, fused and linked, and the hardware pressure of the license plate camera is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of special license plate cameras, and more particularly relates to a mobile vehicle license plate camera device and method. Background technique [0002] Sensing technology has developed rapidly in recent years, and has developed from a single sensor to the existing integrated sensor, that is, the measurement target of the original sensor is relatively single, and only meets the measurement of another or one type of data, but with the continuous development of science and technology As well as the continuous innovation of demand, integrated sensing has been formed, that is, a variety of sensors are organically combined and innovated, which can meet the simultaneous measurement of multiple and multiple types of observations. The development of license plate recognition technology mainly relies on the development of video equipment. At present, the license plate recognition module is mainly divided into two te...
