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.
