Three-dimensional scanning method and device capable of obtaining texture of object

Abstract

The invention provides a three-dimensional scanning method and device capable of obtaining the texture of an object. The method comprises the steps of conducting multi-dimensional image information collection on a scanned object through cameras; synchronizing the acquired information of the plurality of cameras; reconstructing a three-dimensional model with texture information according to the acquired multiple pieces of image information; performing three-dimensional point cloud processing on the reconstructed three-dimensional model with the texture information, and obtaining three-dimensional point cloud data; and carrying out point cloud triangulation and rendering mapping. A three-dimensional model with texture information is obtained, and a large amount of time and operation resources consumed by depth calculation are avoided.The hardware limitation threshold is reduced, and the reconstruction time is shortened to a great extent. An RGB-D camera not only has three-dimensional information, but also has the RGB color and texture information, so that the reconstruction of a fine three-dimensional model with textures, which cannot be realized by a traditional structured light type three-dimensional reconstruction method, can be realized. Therefore, the method and the device can be used for multi-mode fusion of medical images, human body modeling and other application scenes needing fine and accurate models.
