Abstract: The present application relates to a three-dimensional imaging method and apparatus, and a 3D imaging device. The method comprises generating 3D image information by capturing a 3D capture area containing a detected object using a depth camera; extracting a mask of the detected object from the 3D image information; determining an imaging area associated with the detected object based on the mask of the detected object; collecting data from a holographic data collection area containing the detected object by a holographic data collection device, generating holographic data; and performing image reconstruction on the imaging area based on the holographic data.
