Abstract

A 3D real-scene copying device having high cost performance comprises a monocular multi-view stereoscopic vision sensor used for shooting a reconstructed object and a microprocessor used for performing image process and 3D real-scene copying on the reconstructed object; the monocular multi-vies stereoscopic vision sensor comprises a hopper-shaped mirror cavity, a shell, an objective table, a high-definition camera and a semi-spherical LED light source; the microprocessor comprises an image reading module, an image processing module, an image enhancing module, a three-dimensional point cloud obtaining module and a point cloud reconstructing module, the image reading module is used for reading an image, comprising five views, of the reconstructed object, the image processing module is used for segmenting the foreground of the reconstructed object from the image comprising the five views and performing rotation transformation and distortion correction on the image comprising the five views by means of a standardization result of the sensor, the image enhancing module is used for homogenizing the image brightness, in each view, of the reconstructed object, the three-dimensional point cloud obtaining module is used for extracting real three-dimensional coordinate values and color values of points on the surface of the reconstructed object, and the point cloud reconstructing module is used for performing three-dimensional reconstruction on point cloud data.

Description

(1) Technical field [0001] The invention belongs to the application of three-dimensional imaging technology, optical technology and computer vision technology in three-dimensional reconstruction. (2) Background technology [0002] The technology of spatial three-dimensional information acquisition and three-dimensional reconstruction based on computer vision is an application technology with great development potential and practical value. With the deepening of information technology research and the emergence of concepts such as digital earth, digital city, and virtual reality, the development of reverse engineering technology and real scene replication technology has promoted the transformation of surveying and mapping technology from two-dimensional plane to three-dimensional, and from analog surveying and mapping to digital surveying and mapping. evolve. Especially the appearance of 3D printers urgently needs a kind of 3D real-scene duplication technology supporting it....
