Problems solved by technology

[0003] However, the existing image recognition technology for map construction can only stably identify relatively large-scale traffic elements, and cannot stably identify the information contained in small-scale traffic elements such as road signs, especially on highways. The important signs in the image - milestones, because they only account for less than 0.3% of the entire captured image, it is extremely difficult to extract useful information about signs using existing image recognition technology, and the accuracy of sign recognition is not high

Abstract

The invention provides a label identification method and apparatus, a computer device and a storage medium. The method comprises the steps of obtaining a to-be-detected image; based on a trained label identification detection model, performing label identification detection on the to-be-detected image to obtain a label identification in the to-be-detected image; obtaining a label image in the to-be-detected image according to the label identifier, and processing the label image to obtain a processed label image; based on a sign information identification model, sign information identification is carried out on the processed sign image, sign information in the to-be-detected image is obtained, and the sign information comprises a road number and a course value. By adopting the method, the identification accuracy of the sign can be improved, so that more accurate road numbers and history values can be obtained, the sign information of the road can be perfected, the construction precision of the map can be improved, and the labor cost can be saved.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence, and in particular to a label recognition method, device, computer equipment and storage medium. Background technique [0002] Artificial Intelligence (AI) is a comprehensive technology of computer science. By studying the design principles and implementation methods of various intelligent machines, the machines can have the functions of perception, reasoning and decision-making. With the rapid development of artificial intelligence technology, the image recognition function based on computer vision technology accounts for an increasing proportion in the field of image processing, and the infrastructure of more and more application scenarios begins to use this type of image recognition function The map in the driving scene needs to use the above-mentioned image recognition function to identify various traffic signs from massive data to build a high-precision map. [0003...
