A method, system, and storage medium for recognizing Chinese signs on the ground in a parking lot

Abstract

The invention discloses a method for recognizing Chinese signs on the ground of a parking lot, a system thereof, and a storage medium. The method includes: acquiring an image of a parking space and performing preprocessing; using a neural network model to perform Chinese character recognition on the preprocessed image; When there are no Chinese characters in the image, the neural network model outputs the recognition result without Chinese characters; when there are Chinese characters in the image, the neural network model extracts the image of the text area containing Chinese characters and outputs it; when the neural network model outputs no Chinese characters The character recognition result ends the process; when the neural network model outputs the text region image, text correction is performed on the text region image, character segmentation is performed on the corrected text region image to obtain multiple character region images, and multiple character region images are Classify and output the recognition results of Chinese signs on the ground. The invention can identify the Chinese signs on the ground of the parking lot, so as to avoid parking the car in an inappropriate area when parking.

Description

technical field [0001] The invention relates to the technical field of intelligent driving perception, in particular to a method for recognizing Chinese signs on the ground of a parking lot, a system thereof, and a storage medium. Background technique [0002] For automatic driving functions in parking lot scenarios such as autonomous valet parking, the vehicle's perception of the surrounding environment of the parking lot (parking spaces, lane lines, obstacles, and various traffic signs and ground signs) will directly determine the parking success rate and accuracy. Among these environmental information, ground marks are one of the most easily overlooked important information. For many domestic parking lots, ground signs are often used to provide some restrictions on vehicle driving and parking, and there are various types, especially some ground signs with Chinese fonts, such as figure 1 Disabled parking spaces shown, figure 2 EV charging bays shown, image 3 The spec...

Problems solved by technology

For many domestic parking lots, ground signs are often used to provide some restrictions on vehicle driving and parking, and there are various types, especially some ground signs with Chinese fonts, such as figure 1 Disabled parking spaces shown, figure 2 EV charging bays shown, image 3 The special parking spaces for shared cars shown, etc.; the existing recognition models often do not optimize the scenes of these Chinese ground signs, resulting in parking the car in an inappropriate area
