Abstract: A method, an apparatus, and a medium for determining a pose are provided. The method includes: receiving a query image sent by a terminal and N text fields included in the query image; determining a candidate reference image based on a prestored correspondence between a reference image and a text field and based on the N text fields; determining an initial pose of the terminal at the first location based on the query image and the candidate reference image; and sending the initial pose to the terminal. According to the method, a candidate reference image is queried based on a text field, and an initial pose of a terminal is obtained based on a candidate reference image with higher accuracy. Therefore, the obtained pose is more accurate.

Abstract: A text recognition method and apparatus disclosed. The text recognition method includes: obtaining a to-be-detected image; determining a target text detection area in the to-be-detected image, where the target text detection area includes target text in the to-be-detected image, and the target text detection area is a polygonal area including m vertex pairs, m being a positive integer greater than 2; correcting the polygonal area to m−1 rectangular areas to obtain a corrected target text detection area; and performing text recognition on the corrected target text detection area to determine the target text, and outputting the target text.

Abstract: A photographing method and an electronic apparatus are disclosed. The photographing method includes: detecting whether a camera is currently in a stable photographing state; when the camera is currently in the stable photographing state, obtaining image data at a first time point; determining a target photographing type based on the image data at the first time point; when a photographing instruction from a user is received, obtaining image data at a second time point; and processing the image data at the second time point according to an image processing manner corresponding to the target photographing type, to obtain target image data. According to the method, ineffective execution of a scene identification algorithm can be avoided, calculation load is reduced, and an operating speed is increased.
