The invention pertains to a method for taking partially overlapping images of a ground surface from a camera arranged in an aircraft or a spacecraft, the method comprising: while said aircraft or said spacecraft is moving, acquiring (110) images at different instants in time, separated by time intervals; detecting (130), during said moving, position information representative of a position and orientation information representative of an orientation of said aircraft of said spacecraft; using said position information, said orientation information, and the camera's viewing angle to determine (140; 150) maximal values of time intervals for which images with a predetermined amount of spatial overlap can be obtained; and adjusting (160) said intervals towards said maximal values so as to minimize the number of said acquired images while maintaining said predetermined amount of spatial overlap. The invention also pertains to a controller and a system comprising a controller. |
