Embodiment Construction

[0044] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Typical embodiments of the invention are shown in the drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the present invention will be thorough and complete.

[0045] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill i...

Abstract

The invention discloses a three-dimensional reconstruction system and method. The system comprises a main camera. The main camera comprises a detachable camera module and a fixed camera device which are used for collecting large-range images together, and the detachable camera module can be separated from the main camera and can independently collect detail images. The detachable camera module comprises a main processing unit. The main processing unit is used for acquiring a large-range image and carrying out three-dimensional reconstruction according to the large-range image and the detail image. The overall space is required to be roughly reconstructed; the detachable camera module of the main camera and the fixed camera device can be used for jointly acquiring a large-range image. Whena small object needs to be continuously scanned, the detachable camera module can be directly separated from the main camera for use, the detachable camera module is independently used for collectingdetail images, and finally the main processing unit in the detachable camera module carries out three-dimensional reconstruction according to the large-range images and the detail images, so that after normal indoor scanning, the detachable camera module is used for scanning details, and vulnerabilities are filled.

Description

technical field [0001] The present invention relates to the field of three-dimensional reconstruction, in particular to a three-dimensional reconstruction system and method. Background technique [0002] In general, the recovery of details in 3D reconstruction depends on the point cloud density and the accuracy of depth value estimation. Point cloud density mainly depends on the degree of overlap between two frames. In general, the accuracy of depth estimation is inversely proportional to the distance from the object to the acquisition device, that is, the farther the distance, the lower the accuracy and the greater the error. Due to reasons such as fixed height and equipment convenience, the current indoor 3D reconstruction scheme cannot restore details such as desktops, bookshelves, and cups while roughly reconstructing the overall space. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a three-dimensional rec...
