Title:
AN IMAGE SENSOR HAVING A CALIBRATION PATTERN
Document Type and Number:
WIPO Patent Application WO/2020/198928
Kind Code:
A1
Abstract:
An image sensor (9000) with two radiation detectors (100A, 100B), each having a planar surface for receiving radiation; and a calibration pattern (101). The planar surfaces (103A, 103B) of the radiation detectors (100A, 100B) are not coplanar. The image sensor (9000) can capture images of two portions of the calibration pattern (101), respectively using the radiation detectors (100A, 100B). The image sensor (9000) can determine two transformations (108A, 108B) for the radiation detectors (100A, 100B) based on the images of the portions of the calibration pattern (101), respectively. The image sensor (9000) can capture images of two portions (180A, 180B) of a scene (50), respectively using the radiation detectors (100A, 100B), determine projections (181A, 181B) of the images of the portions (180A, 180B) of the scene (50) onto an image plane using the transformations (108A, 108B), respectively, and form an image of the scene (50) by stitching the projections (181A, 181B).
