Example Embodiment

[0046] The following describes the present invention in detail in conjunction with the description of the accompanying drawings. It should be understood that the following only introduces specific embodiments of the present invention, and is not intended to limit the protection scope of the present invention.

[0047] A three-dimensional reconstruction method, such as figure 1 As shown, including the following content and steps:

[0048] 1. Build a multi-camera synchronization acquisition system: such as figure 2 As shown, a three-dimensional space of suitable size and equal length, width and height is divided into a sufficiently large room. This three-dimensional space is the movement space of the object, that is, the object can only be restricted to move in the three-dimensional space. For the convenience of explanation, this three-dimensional space is called the capture space; a certain number of cameras are fixedly installed at suitable positions around the capture space, and ...

Abstract

The invention provides a real-time three-dimensional point cloud reconstruction method based on multiple cameras. The method is characterized in comprising the following steps that: constructing a multi-camera synchronous collection system, carrying out multi-camera system calibration, establishing a projection lookup table and carrying out image collection, object contour segmentation and three-dimensional reconstruction. The invention also provides a real-time three-dimensional point cloud reconstruction system based on multiple cameras. The system comprises a sealed three-dimensional space, a plurality of cameras, a plurality of lamp sources and a computer, wherein the plurality of cameras and the plurality of lamp sources are fixedly installed around the three-dimensional space; the cameras are connected with the computer; and the computer comprises a camera calibration module, a projection lookup table calculation module, an object outline segmentation module and a three-dimensional reconstruction module. The three-dimensional reconstruction disclosed by the invention has the advantages of being higher in accuracy, higher in efficiency, universally applicable and simpler in calculation.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional information, and in particular relates to a multi-camera-based real-time three-dimensional point cloud reconstruction method and system. technical background [0002] 3D reconstruction is a common problem in computer vision, computer graphics and other fields. The so-called three-dimensional object reconstruction refers to obtaining the 2D image or 2.5D depth data of the three-dimensional object in space through the sensing device, and recovering the three-dimensional structure of the object from it. Sensing types may include optically imageable, laser scanning, thermal imaging, etc. 3D reconstruction has many applications in computer-aided design, 3D animation / games, scientific computing and virtual reality, industrial measurement, etc. [0003] Currently, there are three commonly used 3D reconstruction devices or methods on the market. The first is a method based on laser scanning, ...
