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: The technology of this application relates to a pose determining method. The method includes obtaining a first image, when first pose information determined based on the first image meets a pose anomaly condition, displaying prompt information for indicating to photograph a target object, and obtaining, by using the target object in the target image captured by a user based on the prompt, second pose information that does not meet the pose anomaly condition. When high-precision pose information cannot be determined, pose positioning is implemented by using the target object in a scenario. In addition, in a process of determining pose information of a terminal device, prompt information for indicating the user to photograph the target object is displayed, and the user is indicated to photograph the target object, thereby avoiding that the user does not know how to operate or scan an invalid target object.
