Abstract

The invention discloses a method and system for computing three-dimensional space layout based on a scattered perspective image. The method comprises the following steps: extracting a composition cue of a digital image; diffusing the composition cue through interpolation and establishing a successive cue on image space; establishing the geometric mapping relation, which is described by the digital image, between the digital image and the three-dimensional space supporting surface according to the successive cue; and giving any point on the digital image and computing the point of the previous point in the three-dimensional space according to the supporting point position on the image corresponding to the target on which the previous point is located and the geometric mapping relation. The invention takes the drawing principle of the artists as the starting point, gives the scattered perspective geometric solution, establishes the relation between the scattered perspective image and the three-dimensional space described by the image, can effectively locate the target in the image in the three-dimensional space described by the image and ensures consistent location effect and perception effect.

Description

technical field [0001] The invention relates to the intersecting fields of computer vision, computer graphics, virtual reality and multimedia display, in particular to a method and system for calculating three-dimensional spatial layout based on scatter perspective images. Background technique [0002] 3D spatial layout restoration is an important research topic in the field of computer vision and graphics, and has important application value in virtual roaming and perception-based multimedia display. [0003] The current 3D space layout restoration methods are mostly aimed at the photos taken by the camera that meet the focal perspective. This type of method can be divided into single-viewpoint reconstruction and multi-viewpoint reconstruction according to the number of photos used. Single-viewpoint reconstruction is to extract information (such as vanishing point, etc.) from a single image to infer the parameters of the perspective model of the image and the basic three-d...
