Character recognition is accomplished using OCR technology at a variety of image scales. If the recognition results of the characters under multiple scales are inconsistent, a minority of the characters are used for complying with the principle of majority, for example, a certain character is recognized as 'king' under the most scales, a certain character is recognized as 'jade' under the least scales, and finally the character is recognized as 'king'.
S6, obtaining and counting the price information of each target commodity to be settled to obtain the total consumption amount; the method is used for identifying the images of the segmented areas of all the commodities to be detected, obtaining the prices of all the commodities and calculating the total consumption price.
