Abstract

The invention relates to a nameplate text detection method and device, computer equipment and a storage medium. The nameplate text detection method comprises the following steps: positioning a nameplate area in a to-be-detected image, and detecting the nameplate area to obtain contours of a plurality of text regions in the nameplate area, so as to determine feature points in a plurality of contourpoints of the text area; and performing feature mapping on the feature points to obtain target vertexes of the corresponding text areas, and performing perspective correction on the text area according to the feature points and the target vertex to obtain each text area in the corrected nameplate area, so that a guarantee is provided for subsequent machine recognition of the text area in the nameplate area, and the nameplate text recognition accuracy of a machine is improved.

Description

technical field [0001] The present application relates to the technical field of image recognition, in particular to a nameplate text detection method, device, computer equipment and storage medium. Background technique [0002] The nameplate, also known as the nameplate, is mainly used to record some technical data of the manufacturer and the rated working conditions. The nameplate used for the vehicle indicates the basic characteristics of the vehicle, including vehicle model, engine model, engine displacement, engine rated power, vehicle identification number, total mass, load capacity or number of passengers. [0003] The verification of vehicle nameplate information in the traditional annual vehicle inspection is mainly done manually. However, due to the rapid increase in the number of motor vehicles and the large number of vehicles, it is easy to cause fatigue of the auditors and false inspections. Based on this, machine recognition of nameplate text has appeared, but...
