The invention discloses a digital electric meter display recognition method and device, a model training method and device, and belongs to the technical field of image recognition. The method includes: extracting the region of interest from the acquired image of the digital electric meter; determining at least one target region in the region of interest; determining a first rectangular region based on the at least one target region; cutting the first rectangular region to obtain a plurality of second rectangular areas, the width of the second rectangular area is determined based on the width of the first rectangular area and the width of each number in the indication; the images corresponding to the plurality of second rectangular areas are input into the indication recognition model, Obtain the indications output by the indication recognition model. The invention can reduce the cost of collecting electricity indications and improve the efficiency and accuracy of collecting electricity indications, and can be used for the identification of the indications of digital electricity meters.
Description
technical field [0001] The invention relates to the technical field of image recognition, in particular to a method and device for display recognition of a digital electric meter, and a model training method and device. Background technique [0002] The digital ammeter records the user's power usage by collecting pulse signals, and automatically records and saves the data. At present, it is usually necessary to manually record the readings on the digital ammeter. [0003] However, since the number of digital meters is usually large, the amount of data collected manually is large, resulting in high cost, low efficiency and error-prone data. Contents of the invention [0004] The present invention provides a digital electric meter indication recognition method and device, model training method and device, which can reduce the cost of collecting electrical indications and improve the efficiency and accuracy of collecting electrical indications. The technical solution is as f...
