<p>A device for detecting optical-axis offset of a lens in an apparatus. The device comprises: a standard image acquiring module (110), used for focusing, at a shooting position, a standard lens assembled in the apparatus, shooting a picture sample, and acquiring a standard image of the picture sample; a reference coordinate system setup module (120), used for setting up a reference coordinate system by using the center of the standard image as a coordinate origin; a test image acquiring module (130), used for focusing, at the shooting position, a to-be-detected lens assembled in the apparatus, shooting the picture sample, and acquiring a test image of the picture sample; a test cursor position determining module (140), used for determining the position of a test cursor in the reference coordinate system by using the center of the test image as the test cursor; and an optical-axis offset detecting module (150), used for determining optical-axis offset and/or an optical-axis offset angle of the to-be-detected lens according to the position. The device can detect the optical-axis offset of the lens in the apparatus during assembly. Also provided is a method for detecting optical-axis offset of a lens in an apparatus.</p> |
