An imaging system on an aerial vehicle, includes: a group of rotating camera including at least a first and a second rotating cameras on the aerial vehicle; and a control part which controls a first virtual rotation track of the first rotating camera and a second virtual rotation track of the second rotating camera and allows shots to be taken at multiple photograph-shooting points on the first virtual rotation track and the second virtual rotation track; wherein the control part controls a set of multiple photograph-shooting points on the first virtual rotation track and those on the second virtual rotation track to be substantially in a grid shape. Accordingly, a 3D image could be acquired by using the group of rotating cameras on the aerial vehicle during a relatively short endurance flight and more information on images created in such a method could be estimated.
