Abstract

The invention provides an instrument reading recognition method and device, equipment and a storage medium, which relate to the technical field of image processing, and are used for improving the accuracy of instrument reading recognition. The method comprises the following steps of performing target detection on a target image containing an instrument, determining an instrument area in the target image, and determining a plurality of character areas in the instrument area, performing pointer recognition on the instrument area, and determining a target straight line where the direction pointed by a pointer of the instrument is located, performing character recognition on each character region in the plurality of character regions, and determining characters corresponding to each character region, and determining the reading of the instrument according to the determined target straight line and the determined characters.

Description

technical field [0001] The present application relates to the technical field of image processing, and provides a method, device, device and storage medium for recognizing meter readings. Background technique [0002] With the development of the times, industrial production has also entered the information age. Among them, various types of precision instruments are typical representatives of industrial informatization. However, due to the variety of instrument types and the huge number of instruments, it is difficult to manually read instrument readings. This method is time-consuming and labor-intensive, and there are certain subjective errors. Furthermore, in order to shorten the time for determining the meter reading and improve the accuracy of the meter reading, it is now gradually developed to use the traditional image processing method to determine the meter pointer reading. [0003] However, the current method of using traditional image processing to recognize pointer...
