Embodiment

[0023] The technical solution for two-dimensional image reconstruction in this embodiment is mainly divided into three parts: acquisition of camera internal parameter matrix, calculation of homography matrix, and plane projection.

[0024] (1) Acquisition of the internal parameter matrix: the projection model of the camera is a pinhole model, and the point P(X,Y,Z) in the objective world corresponds to the point p(u,v) on the two-dimensional plane (the three-dimensional plane to the two-dimensional plane projection), has the following relationship: λ u v 1 = f u 0 u 0 ...

Abstract

The invention discloses a two-dimensional image reconstruction method of a target in a two-dimensional video image. The method comprises the following steps of: (1) calculating by utilizing model parameters of known shooting equipment for shooting a two-dimensional image to obtain the internal parameter matrix of the video camera; (2) calculating the external parameter matrix and the homography matrix of the video camera according to the internal parameter matrix of the video camera obtained in steps (1); and (3) solving corresponding pixel points on a projection plane according to the homography matrix of the video camera and known planar points of a two-dimensional image space, and circulating in sequence to reconstruct the two-dimensional image. The method can be used for saving a great quantity of calibrated image identification and calculating time, saving computer resource, improving the calculating efficiency and well serving for reconstruction and identification of the two-dimensional image.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a two-dimensional image reconstruction method for a target in a two-dimensional video image, so as to facilitate two-dimensional image recognition. Background technique [0002] Computer vision mainly studies how to use computers to realize human visual functions, that is, to use two-dimensional image projection to reflect the perception and understanding of the objective three-dimensional world. At present, image reconstruction mostly uses camera calibration to reconstruct a three-dimensional space from the known two-dimensional image, and calculates the actual position of the plane pixels of the two-dimensional image in the three-dimensional space. and picture it. [0003] This kind of general image reconstruction research has insufficient value for a specific specific research (such as two-dimensional image recognition). In two-dimensional image recognit...
