Abstract

The invention discloses a video image three-dimensional position extraction method, which comprises the following steps of S1, establishing a three-dimensional scene of a real site through a 3D modeling tool; s2, setting a virtual camera at a corresponding position of the three-dimensional scene according to the position of the video image acquisition equipment of the real scene, and calibrating the angle between the video image acquisition equipment and the virtual camera; s3, constructing a UV mapping table for the three-dimensional scene through a Shader shader; s4, according to the UV mapping table, extracting a three-dimensional position corresponding to a pixel point of the video image shot by each virtual camera, and quickly finding the three-dimensional position through the pixel position of the video image; according to the invention, the problem of automatic extraction of the three-dimensional position of the video image is solved.

Description

technical field [0001] The invention relates to the field of image signal processing, in particular to a method for extracting a three-dimensional position of a video image. Background technique [0002] Nowadays, video image acquisition technology is very mature and common. Video acquisition equipment is installed in small communities to entire cities, which can collect video images in real time. [0003] With the development of computer technology, 3D technology, especially 3D modeling technology has also been greatly developed in recent years. This technique is widely used in the display work of urban communities. Visitors can view the urban community scenery at a glance from the 3D simulation model scene displayed on the screen combined with the real images. [0004] However, how to correspond one-to-one between the position of the 3D scene and the position of the image captured by the video capture device in real time is an engineering difficulty that needs to be solv...
