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: Transitions between street view images are described. The described techniques include: obtaining an original street view image and a target street view image; constructing a three-dimensional model corresponding to the original street view image by three-dimensional modeling; obtaining matching pairs of feature points that are extracted from the original street view image and the target street view image, and simulating a virtual camera in the three-dimensional model according to matching pairs of feature points to capture street view image sequence; and switching from the original street view image to the target street view image according to the street view image sequence. Transition stability is thereby improved.
