Problems solved by technology

[0003] However, in the current 3D restoration method, since the feature extraction in the image processing method can only extract more obvious corner features or edge features, it is impossible to extract more image features for areas without obvious features on the object, resulting in the need to use High-quality camera for image acquisition, which makes the cost of 3D restoration relatively high
Moreover, when there are few image features, it is impossible to effectively and accurately generate a 3D model of an object.

Abstract

The invention provides a three-dimensional restoration method and system, terminal equipment and a storage medium, and the method comprises the steps: obtaining a second image from at least four pieces of image collection equipment after projection equipment projects a preset pattern to a to-be-scanned target; wherein the visual angle areas of the adjacent image acquisition devices in the at leastfour image acquisition devices are overlapped pairwise; wherein the second image comprises a to-be-scanned target projected with a preset pattern; performing feature extraction on the second image, and performing matching according to the extracted image features to obtain an image pair; wherein the image pair comprises at least two second images with overlapped scenes; respectively carrying outfeature point matching on the image pairs to obtain matching groups; performing calculation according to the matching group to obtain spatial points on the to-be-scanned target corresponding to the image features; and generating a three-dimensional model corresponding to the to-be-scanned target according to the space points. The method increases the number of image features, improves the precision of three-dimensional restoration, and reduces the cost of three-dimensional restoration.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a three-dimensional restoration method, system, terminal equipment and storage medium. Background technique [0002] The 3D model of an object is used in a wide range of fields, such as design simulation, virtual reality, 3D movies and other fields. The establishment of the 3D model of the object needs to use the camera to take a panoramic shot of the object, perform feature recognition on the captured image, and then perform 3D restoration to construct the corresponding 3D model of the object. [0003] However, in the current 3D restoration method, since the feature extraction in the image processing method can only extract more obvious corner features or edge features, it is impossible to extract more image features for areas without obvious features on the object, resulting in the need to use High-quality cameras are used for image acquisition, which makes the cost o...
