Method and mobile detection vehicle for detecting geometric and time phase resolution of space camera

The invention relates to a method for detecting geometric resolution of a space camera, a method for detecting time phase resolution of the space camera, and a mobile detection vehicle for detecting geometric and time phase resolution of the space camera. The conventional ground fixed target form is changed, and a geometric resolution target is combined with the mobile vehicle to form a mobile target, so that geometric resolution detection and mobile calibration function of different time phases are realized, and the test precision of the geometric resolution of the optical camera in a random direction is improved. The conventional ground fixed target can be stored in a cabin, can be quickly arranged in emergency and can also play a role in complementing a hard target of a vehicle body and a conventional soft target. The invention can be widely applied in the fields of detection and calibration of aerospace optical cameras and imaging systems.
