Description

Technical Field

[0001] The utility model relates to the technical field of optical imaging, in particular to a mechanism for calibrating the focusing curve of a zoom camera with a collimator. Background Technique

[0002] A varifocal zoom camera (Optical Zoom) refers to a digital camera that relies on the optical lens structure to achieve zooming. The optical zoom method of a digital camera is similar to that of a traditional 35mm camera, that is, the lens is moved to magnify and reduce the scene to be photographed. The larger the optical zoom ratio, the farther the scene that can be photographed. Obviously, there are two ways to change the viewing angle. One is to change the focal length of the lens. In photography terms, this is optical zoom. By changing the relative positions of the lenses in the zoom lens, the focal length of the lens is changed. The other is to change the size of the imaging surface, that is, the length of the diagonal of the imaging surface. In digital photography, this is called digital zoom. In fact, digital zoom does not change the focal length of the lens, but only changes the viewing angle by changing the angle of the diagonal of the imaging surface, thus producing an effect of "equivalent" change in the focal length of the lens.

[0003] Currently, to calibrate the focusing curve of a zoom camera's autofocus, the camera and the collimator are placed on a table, and the center of the camera is aligned with the star focus card in the collimator by means of padding. The calibration speed is slow and it is easily affected by external forces, which affects the calibration accuracy. Content of the Utility Model
