| description | Optical geometry calibration devices, systems, and related methods for x-ray imaging are disclosed. An optical-based geometry calibration device is configured to interface with a two-dimensional (2D) imaging device to perform three-dimensional (3D) imaging. The optical-based geometry calibration device includes one or more optical cameras fixed to either an x-ray source or an x-ray detector, one or more markers fixed to the x-ray detector or the x-ray source, with each of the one or more optical cameras being configured to capture at least one photographic image of one or more corresponding optical markers when each x-ray image of the object is captured, and an image processing system configured to compute positions of the x-ray source relative to the x-ray detector for each 2D projection image based on the at least one photographic image of the one or more markers. |
