Images of the reconstruction space captured by N cameras are acquired as N current images in response to an object entering the reconstruction space. Foreground-background differences of all position points in the N current images are obtained according to the N current images and N corresponding initial background images captured by the N cameras when the reconstruction space is empty. Corresponding foreground-background differences of position points in the N current images are fused according to a corresponding relationship between all position points in the N current images and all position points in the reconstruction space, to obtain a foreground-background difference of each position point in the reconstruction space. All position points in the reconstruction space are filtered based on the foreground-background difference of each position point in the reconstruction space and the preset foreground-background threshold, to reconstruct the object three-dimensionally."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Three-dimensional reconstruction method and apparatus","description":"A method and an apparatus for three-dimensional reconstruction.
