Embodiment Construction

[0027] In order to further understand the content of the present invention and make the purpose, technical solution and advantages of the present invention more clear, the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] The embodiment designed by the present invention provides a voxel-based three-dimensional reconstruction and texture mapping method. It includes the following steps:

[0029] Step S1: Set up N RGBD cameras 120 around a storage platform 110 at intervals in the circumferential direction, such as image 3 No.1, No.2, ..., No.n, and make each RGBD camera face to the center of the storage platform 110, so as to build a device with a fixed structure for subsequent shooting processing;

[0030] Step S2: Place the target object in the center of the storage platform 110, let N RGBD cameras 120 simultaneously shoot the target object, process the RGB images collected by each RGBD camera 120 throu...

Abstract

The invention relates to a rapid three-dimensional modeling method based on voxels and a system thereof. The N RGBD cameras with the number larger than 1 are sequentially placed around a storage platform at intervals to shoot a target object, and then an image processing unit, a voxel cutting unit, a voxel fusion unit, a voxel filling unit, a grid extraction unit and a texture generation unit are arranged. A vivid three-dimensional reconstruction model of the target object is obtained. The problem that information is insufficient when three-dimensional reconstruction is carried out on the target object under a limited view angle is solved, and meanwhile rapid three-dimensional reconstruction is carried out on the target object. The method is rapid and accurate.

Description

technical field [0001] The invention belongs to the field of three-dimensional modeling, in particular to a voxel-based fast three-dimensional reconstruction method and system of an object, which rapidly reconstructs the geometric texture details of an object by only using limited RGBD camera data. Background technique [0002] At present, the commonly used 3D reconstruction methods are divided into the following types: 1. Using a single camera with a depth camera to slowly move and shoot around a specified object, such as the technology proposed in the paper "KinectFusion", although it can obtain better However, due to the unavoidable shaking of the hand-held camera when shooting, or the rapid change of moving speed when holding the camera, resulting in motion blur, multiple repeated scans are required to obtain better results; 2. Using multiple cameras with depth cameras , respectively fixed at the specified position, the specified object is located in the middle of the ca...
