Problems solved by technology

But when the parking lot is finished and the parking lot is left, if the license plate is correctly recognized as the license plate A at the exit of the parking lot, then there is no vehicle matching the license plate A in the current parking directory of the parking lot, which will cause parking fee obstacles
For large parking lots, when there are many license plate recognition errors, parking fee obstacles often occur, and the consequences are very serious

Embodiment Construction

[0038]In the specific implementation process, for small parking lots, the above-mentioned imported car rear sense, imported car rear photo and recognition, and export car rear sense, export car rear photo and recognition can be omitted, which is equivalent to removing the automatic review mechanism and only retaining Manual reviewers review. Although the efficiency of the review will be low, the cost of its technical implementation is also low for small parking lots.

[0039] That is to say, according to the scale of the parking lot, the review of the license plate recognition can have different technical implementation forms, but the essence is to ensure that the parking information table of the parking lot is 100% correct through review, and then ensure the technical foundation of the subsequent charging operation of the parking lot. Trustworthy, all belong to the scope of claims of the present invention.

Abstract

The invention provides a parking charge method completely based on license plate recognition in a parking lot. By means of establishing an automatic reexamining mechanism for license plate recognition at a headstock and a tailstock, the effect that a parking information table created automatically in real time by the parking lot is 100% correct is ensured, the fastness and reliability of a technological base for follow-up charge operation of the parking lot are further ensured, and parking charge conflicts caused by license plate recognition errors are avoided.

Description

technical field [0001] The invention relates to a license plate recognition technology and a wireless network-based parking charging technology in a parking lot related to the license plate recognition. Background technique [0002] Although the license plate recognition technology is more and more widely used in the parking fee of the parking lot, the license plate recognition technology itself is not perfect, and some license plates may not be recognized or recognized incorrectly, causing many parking fee problems. [0003] License plate recognition involves license plate positioning, character segmentation, and character recognition. The basic principle is based on thresholds. When a parameter value in the process of license plate positioning, character segmentation, and character recognition is greater than the set threshold, the corresponding value is not greater than the set threshold. The value of the threshold is different or opposite, which eventually leads to licen...
