摘要： 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. After application of the embodiments of the present disclosure, smooth panorama-based inter-viewpoint transition can be realized, and the effect of smooth walkthrough can be enhanced, by accurate determination of distance between the viewpoints.
