Three-dimensional model building method and apparatus, mobile terminal, storage medium and device

Abstract

The invention discloses a three-dimensional model building method and apparatus, a mobile terminal, a storage medium and a device. The method comprises the steps of controlling a first laser device and a second laser device to project line laser for calibrating a to-be-scanned object; collecting video image information of the to-be-scanned object under the irradiation of the line laser through a front camera or a back camera of the mobile terminal; receiving the video image information, and extracting the video image information to obtain first light bar information and second light bar information; according to the first light bar information, generating a first three-dimensional model, and according to the second light bar information, generating a second three-dimensional mode; and fusing the first three-dimensional model and the second three-dimensional model to obtain a three-dimensional model of the to-be-scanned object. By implementing the three-dimensional model building method, during scanning, the line laser irradiates the to-be-scanned object from different angles, so that incomplete scanning due to shielding of the line laser is avoided; and the three-dimensional model built by fusing the two models is more exquisite and vivid, and is better in effect.

Description

technical field [0001] The present invention relates to the technical field of three-dimensional scanning, and in particular, to a method, device, mobile terminal, storage medium and device for constructing a three-dimensional model. Background technique [0002] 3D scanning and reconstruction is a high-tech integrating optical, mechanical, electrical and computer technologies. It is mainly used to scan the external structure and color of an object to obtain the spatial coordinates of the object. Its significance lies in that it can convert the three-dimensional information of the object into a digital signal that the computer can directly process, which provides a very convenient and fast means for the digitalization of objects. 3D scanning and reconstruction technology has a wide range of applications in many fields, such as reverse engineering calculations in industry, surface detection in medical, and product quality control in production.
