Embodiment Construction

[0063] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, and the following embodiments do not constitute a limitation of the present invention.

[0064] The technical idea of ​​the present invention is to build a three-dimensional reconstruction system, which is mainly composed of an image acquisition device, a shooting control platform and a visual information processing system. The image acquisition device adopts a binocular camera, which is responsible for acquiring image information of the observed object; the shooting control platform is mainly responsible for controlling the shooting angle of the shooting camera to ensure 360-degree panoramic shooting; the visual processing system mainly uses the acquired image information as input data, and uses three-dimensional The reconstruction method accurately reconstructs the three-dimensional structure of the object.

Abstract

The invention discloses a non-contact nondestructive omnibearing three-dimensional modeling method. The method comprises the following steps: calibrating a binocular camera by using a calibration board, and obtaining a stereo image pair; calculating an adaptive cross for each pixel in the image; estimating an adaptive matching window for each pixel according to the adaptive cross; obtaining matching cost by using the adaptive matching window, and respectively building a data item, a refined item, a smooth item and a division item by using the matching cost; then carrying out energy minimization on an energy equation to obtain final parallax distribution; and carrying out three-dimensional reconstruction according to the final parallax distribution. By adopting the non-contact nondestructive omnibearing three-dimensional modeling method, three-dimensional reconstruction is carried out by using a stereo vision method; the damage to an object caused by a contact three-dimensional modeling method is avoided; the three-dimensional reconstruction accuracy is effectively improved by adopting the adaptive matching cost method; the non-contact nondestructive omnibearing three-dimensional modeling method has good practicability.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a non-contact and non-destructive omni-directional three-dimensional modeling method. Background technique [0002] With the development of signal processing science and computer technology, computer vision as a new field of artificial intelligence has gradually formed and has been greatly developed. Computer vision technology uses cameras instead of human eyes to obtain scene images and convert them into digital signals. Visually perceive and interpret the objective world instead of the human brain. Although it is not yet possible for computers, robots or other intelligent machines to have vision as efficient, flexible and general as humans and other creatures, vision theory and technology have developed rapidly since the 1950s. Helmets are aimed at electronic image stabilization on military vehicles, from image guidance on missiles to military target recognition, compu...
