Embodiment Construction

[0023] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0024] Computed Tomography (CT) uses X-ray beams to scan a layer of a certain thickness of the object to be scanned, and the detector receives the X-rays that pass through this layer, converts them into visible light, and then converts them into electrical signals by photoelectric conversion. After being converted into a digital signal by an analog / digital converter, a computer is used to generate a scanned image.

[0025] Three-dimensional scanning technology is an advanced fully automatic high-precision three-dimensional scanning technology. By measuring the three-dimens...

Abstract

The present application relates to a three-dimensional model reconstruction method, apparatus, computer device and storage medium. The method comprises: scanning an object to be scanned according to apreset strategy, and obtaining first scanning data and second scanning data; the first scanning device for acquiring the first scanning data is different from the second scanning device for acquiringthe second scanning data; performing grid processing on the first scanning data to obtain the first grid data; performing fusion processing on the second scanning data to obtain the second grid data,and splicing the first grid data and the second grid data; according to the splicing result, the first mesh data and the second mesh data are stitched together to obtain the final mesh data and the three-dimensional model is reconstructed. Through two kinds of scanning equipment, when the scanning data acquired by the three-dimensional scanner is missing, the second kind of scanning equipment isused to make up for the leakage, reduce the complexity of the algorithm, improve the accuracy, and further make the reconstruction of the three-dimensional model more accurate.

Description

technical field [0001] The present application relates to the technical field of three-dimensional model reconstruction, in particular to a three-dimensional model reconstruction method, device, computer equipment and storage medium. Background technique [0002] Three-dimensional scanning refers to a high-tech that integrates optical, mechanical, electrical and computer technologies. It is mainly used to collect and analyze the geometric structure and appearance data of objects or environments, and perform three-dimensional reconstruction of the collected data to obtain the image of the scanned object. 3D digital model. Scan the impression with a 3D scanner, obtain the impression data from multiple angles, and use the high-precision impression data obtained by the 3D scanner to perform 3D reconstruction and finally obtain a 3D model. [0003] In the current existing technology, when using a 3D scanner to scan the impression, there are problems of local narrow and long impr...
