Title: METHOD AND DEVICE FOR ANALYZING SPATIAL POSITION INFORMATION FROM TWO-DIMENSIONAL IMAGE
Abstract:
A method and device for analyzing spatial position information from a two-dimensional image. An identifier is provided at a target end, and physical spatial information of the identifier is recorded and stored; an image of the identifier is captured, two-dimensional image information of the identifier and spatial position information thereof captured are combined, a mathematical mapping relation between the two-dimensional image information and the spatial position information is acquired, position information of a target on the two-dimensional image is determined, and spatial information of the target on the two-dimensional image is produced by conversion by means of the mathematical mapping relation between the two dimensional image information and the spatial position information. The method allows highly precise, inexpensive, and super-fast positioning, measurement, and analysis of spatial information.
