Free multi-vision angle, real-time three-dimensional reconstruction system and method

Abstract

The present invention relates to a free multi-view real time three-dimension reconstructing system and a method thereof. The system consists of a CCD vidicon, a computer assembled with a multi-channel image collecting card and a plane demarcating template. Two concentric circles and eight tangential paths with prolonged lines crossing the circle center are drawn on the center of the plane demarcating template and are used for demarcating the vidicon parameter. In the technical proposal of the present invention, a reconstructing object is fixed at the center of the demarcating template; the template is held by hand to drive the reconstructing object to rotate freely within the range of the view and the depth of field of a vidicon at a fixed position; image collection and object reconstruction are processed synchronously, thereby being capable of finding concentrated missed view in time and displaying reconstruction result in real time. The three-dimension reconstructing method comprises the steps of image segmentation, full-automatic vidicon demarcation and the three-dimension reconstruction of object shape, etc. The three-dimension reconstructing system of the present invention isbased on the computer vision technology, and the reconstructing method is based on the profile recovery shape and can realize free multi-view real time three-dimension reconstruction.

Description

technical field [0001] The present invention relates to technical fields such as computer vision, computer technology, image processing, etc., especially a free multi-angle, real-time three-dimensional reconstruction system and method. Background technique [0002] Three-dimensional reconstruction is an important research content in computer vision, the purpose is to obtain the three-dimensional features of objects in space from two-dimensional information, and establish a three-dimensional model of the object. With the development of network and digitization in today's society, 3D reconstruction has broad application prospects in the fields of e-commerce, online tourism, digital museums and 3D games. [0003] At present, the research methods of 3D reconstruction are mainly divided into two categories: one is active methods, such as laser scanners, which can obtain high reconstruction accuracy, but the equipment is expensive and requires a special light source device to prov...

Problems solved by technology

At present, there are two main methods. One is to use the turntable to rotate and reconstruct the object, and record the angle of the turntable. This method can obtain higher reconstruction accuracy, but requires high-precision rotation angle control; the other method is to reconstruct the object around the camera. The object collects multi-view images in a regular or free manner. The hardware of this method is relatively simple, but there are certain limitations in application, that is, the image acquisition and object reconstruction are divided into two independent steps, so it cannot be found in time.
