MULTI-CAMERA CO-CALIBRATION METHOD IN 3D MODELING

摘要

A calibration method in 3D modeling. The method comprises: a first collection device collecting an image of an object A; a second collection device collecting an image of an object B; both the first collection device and the second collection device collecting an image of an object C, wherein the object A is not in the collection range of the second collection device, the object B is not in the collection range of the first collection device, the object A is a calibration object and the object B is a target object, or the object A is a target object and the object B is a calibration object, and the calibration object has multiple calibration points; and calibrating the coordinates of the target object according to the coordinates of the multiple calibration points. Absolute size calibration of a long-range target object is realized by means of a multi-camera relay photographing method.
