Abstract: The disclosure provides a method and device for three-dimensional reconstruction, applied to the field of image processing. The method includes: obtaining a first depth map, which is photographed by a first photographic device, and obtaining a second depth map, which is photographed by a second photographic device; merging the first depth map with a first three-dimensional model according to a position of the first photographic device to obtain a second three-dimensional model; and merging the second depth map with the second three-dimensional model according to a position of the second photographic device to obtain a third three-dimensional model.

Abstract: The present invention provides a method and device for calibration, applied to the field of image processing. The method comprises: obtaining a first two-dimensional image of a calibration object with a marking point and a first depth map of the calibration object, obtaining calibrated three-dimensional model data of the calibration object, determining a first three-dimensional marking point in the first depth map corresponding to the marking point based on the marking point in the first two-dimensional image, determining a second three-dimensional marking point in the three-dimensional model data of the calibration object corresponding to the marking point based on the marking point in the first two-dimensional image, and determining a first matrix. By adoption of the method mentioned above, when the device for photographing the three-dimensional image is calibrated, it is simple and feasible, and the operation difficulty is small.
