Abstract

The invention provides a click-to-read target recognition method and system, a storage medium and electronic equipment. The method comprises the following steps: respectively obtaining and marking a long-focus camera shooting area and a wide-angle camera shooting area on a book corresponding to a long-focus camera and a wide-angle camera; when a user performs a click-to-read operation, starting awide-angle camera to obtain a user click area; if the user click area is in the wide-angle camera shooting area but out of the long-focus camera shooting area, identifying and capturing a user click target through a fingertip algorithm; if the user click area is in the long-focus camera shooting area, starting a long-focus camera; obtaining a book thickness corresponding to the user click area; and acquiring an image of a common region of the long-focus camera and the wide-angle camera, and identifying and capturing a user click target through a fingertip algorithm in combination with the bookthickness. According to the method, through the upper and lower cameras with different focal lengths, the problem that the spatial resolution of a fixed-focus wide-angle camera is low, resulting in fuzzy recognition of distant book fonts, is solved.

Description

technical field [0001] The invention relates to the field of intelligent terminals, in particular to a point-reading target recognition method, system, storage medium and electronic equipment. Background technique [0002] Finger-pointing book is a technology that uses the finger to point to the relevant content of the book, and the machine uses AI algorithms, intelligent voice, image intelligent recognition and fingertip positioning to accurately identify the content pointed by the finger, thereby performing text recognition. [0003] The current finger pointing book mainly acquires images through a single fixed-focus wide-angle high-definition camera for text recognition, but it is difficult to obtain and recognize text information of distant books, and the spatial resolution is low, resulting in the problem of low recognition rate of distant text content; In addition, because the camera is at a certain angle with the book, the camera is not directly above the book. When t...
