A process for the autofocus of an imaging optical sensor of an air image camera or a world space the camera and the aerial image - or world space camera

摘要

The present invention relates to a process for the autofocus of an imaging optical sensor (4) of an air image camera or a world space camera (1), wherein the camera (1) at least one lens (2), at least one sensor (4) as well as at least one actuator (5) for the relative displacement of the objective lens (2) and the sensor (4), wherein the camera (1) at least one laser (8, 9) associated therewith, whose emission direction parallel to the optical axis (6) of the camera (1) is aligned, wherein an evaluation - and control unit (7) the laser (8, 9) controls a pulsed nature and the received reflected impulse response (11) analyzes, wherein said evaluation - and control unit (7) from the impulse response (11) a virtual object plane (e_V) or virtual object distance (d_V) determined, in their or its a function of the actuator (5) lens (2) and the sensor (4) is displaced relative to one another, as well as such an aerial image - or world space camera (1).
