  • Publication number: 20230171389
    Abstract: A 3D image synthesizing apparatus models a background to be imaged for each of positions to generate a background model at each of positions, sets a first IAD of a camera at each position based on the background model at each position, obtains a 3D image of the background imaged by the camera based on the first IAD, selects a target position corresponding to an object to be imaged from among the positions, sets a second IAD of the camera at the target position based on the first IAD set at the target position, obtains a 3D image of the object imaged by the camera based on the second IAD, and synthesizes the 3D image of the background and the 3D image of the object.
