Three-dimensional restoration method and system, terminal equipment and storage medium

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 generati
