Method and device for detecting consistent rotation of optical axis and mechanical axis of photoelectric camera

The invention discloses a method and a device for detectin consistent rotation of an optical axis and a mechanical axis of a photoelectric camera. The detection method comprises the following steps: asupport rod on which a photoelectric camera is fixed is connected to a support rack in a rotatable manner, and video output of the photoelectric camera is connected to a computer; an original point Oof a coordinate system of the photoelectric camera is aligned with a target aiming point m, the support rod is rotated around an axis of the support rod, coordinates (xi, yi) of the target aiming point m in the coordinate system of the photoelectric camera is extracted and recorded every 360 degrees/n, n is an integer ranging from 4 to 24, and the extracted and recorded coordinates (xi, yi) are averaged to be ([delta]x, [detal]y) which is deviation the optical axis from the mechanical axis. The device for the method is provided with the support rack, a lateral test tube is fixedly connected to the support rack through
