The invention belongs to the technical field of
computer vision, and particularly relates to a multi-view image three-dimensional
reconstruction method, which comprises the following steps of: firstly, inputting a small amount of two-dimensional images, generating a color
point cloud through depth
estimation, initializing a three-dimensional
Gaussian model, and performing coarse-grained reconstruction by combining
luminosity loss and geometric regularization; secondly, planning a camera track based on geometric distribution of the rough model, and collecting a multi-view
image sequence; thirdly, performing fine adjustment and repair on the image by using a
diffusion model fusing the camera
pose and the visual features; and finally, iteratively optimizing the three-dimensional
Gaussian model by using the repaired image, and outputting a high-precision three-dimensional reconstruction result. According to the method, high-quality reconstruction can be achieved only through sparse
view angle images, and dependence of a traditional method on a large amount of data is broken through. Through composite condition coding and dynamic
trajectory optimization,
geometric consistency and texture authenticity are effectively improved, artifacts are avoided, and calculation efficiency and reconstruction precision are considered at the same time.
