Embodiment Construction

[0038] The embodiment of the present invention discloses a license plate information collection device and method, which solves the problem that the existing license plate camera only relies on one camera acquisition module to capture images within a fixed range from a fixed angle, which easily causes the obtained license plate image to be unclear and incomplete Furthermore, it is difficult to be recognized by the license plate recognition system as a technical problem.

[0039] see Figure 1 to Figure 6 , the present invention provides an embodiment of a license plate information collection device, including: a processing module 2 and at least two camera modules 1 .

[0040] Each camera module 1 is arranged at a preset angle to capture license plate images from different angles.

[0041] like image 3 As shown, the camera module 1 can be arranged in parallel; as figure 2 As shown, the camera module 1 can also be arranged in a divergent manner. It can be understood that wh...

Abstract

The invention discloses a license plate information collecting device and method. The license plate information collecting device comprises a processing module and at least two camera modules and is characterized in that each camera module is arranged at a preset angle and can take license plate pictures from different angles; the processing module is used for performing quality judgment on the multiple license plate pictures and selecting the license plate pictures satisfying preset identification requirements. By the license plate information collecting device, the technical problem that dueto the fact that an existing license plate camera only uses one camera module to take the pictures in a fixed range from a fixed angle, the acquired license plate pictures are unclear and incompleteand cannot be identified by a license plate identification system is solved.

Description

technical field [0001] The invention relates to the technical field of traffic, in particular to a license plate information collection device and method. Background technique [0002] Traffic technology refers to technologies applied in the field of transportation, such as traffic light control technology, license plate information collection technology, etc. [0003] Currently, license plate information is collected by license plate cameras. The existing license plate camera has only one camera acquisition module, the acquisition direction of the camera acquisition module is also fixed, and the field of view acquired by the camera acquisition module is also limited. [0004] Therefore, when the vehicle tilt angle is too large or the license plate is bent unevenly, the license plate camera only relies on a camera acquisition module to capture images within a fixed range from a fixed angle, which can easily cause the obtained license plate image to be unclear and incomplete...
