3D real-scene copying device having high cost performance

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 standard
