Abstract: A method and device for panorama-based inter-viewpoint walkthrough and a machine readable medium are provided. The method includes: selecting a current viewpoint image from a panorama, and obtaining a three-dimensional model of the current viewpoint image; selecting a sub-image from the current viewpoint image to perform a feature detection, so as to obtain feature points of neighboring viewpoints; performing a matching calculation on the feature points of the neighboring viewpoints, and determining a distance between the neighboring viewpoints according to a result of the matching calculation; and performing three-dimensional walkthrough on the three-dimensional model of the current viewpoint image, where a walkthrough depth is the distance between the neighboring viewpoints.

Abstract: A terminal device may comprise a non-transitory processor-readable medium and a processor in communication with the storage medium. The storage medium may include a set of instructions for displaying a perspective view map to a user. The processor may be configured to execute the set of instructions to obtain a target image showing a vicinity of a target location in a perspective view along a target direction; determine a plurality of target objects that locate in the vicinity of the target location along the target direction; generate an overlaid target image by overlaying target information associated with the target objects on the target image; and display the target image overlaid with the target information.
