Abstract: Aerial camera systems are disclosed, including an aerial camera system that comprises at least one camera arranged to capture a plurality of successive images; the at least one camera being rotatable such that the field of view of the camera traverses across a region of the ground that includes multiple different swathes extending in different directions, the at least one camera having a steering mirror to direct light reflected from the ground onto a lens assembly, the lens assembly having a central longitudinal axis extending in a direction generally parallel to a direction of movement of a survey aircraft; and the system arranged to control the at least one camera to capture successive images at defined intervals as the at least one camera rotates.

Abstract: An aerial vehicle has a fuselage, at least one wing, propulsion means for forward flight and at least two pairs of arms. Each arm supports at least one rotor powered for vertical take-off and landing (VTOL) and each arm is in a deployed position for vertical take-off or hovering and transitions to a retracted position for forward flight using the at least one wing, and the arms re-transition to a deployed position for vertical landing or hovering.

Abstract: An aerial camera system is disclosed that comprises at least one camera arranged to capture a plurality of successive images. Each camera including at least one respective image sensor, and the field of view of each camera is movable in a substantially transverse direction across a region of the ground. The system also includes a stabilisation assembly associated with each camera that has at least one steering mirror. The steering mirror is controllably movable so as to translate the optical axis of the camera relative to the at least one image sensor in synchronization with image capture, so as to effect stabilisation of an image on the at least one image sensor during image capture as the field of view of the camera moves in a substantially transverse direction across a region of the ground. The system is arranged to control the at least one camera to capture successive images at defined intervals as the field of view of the camera moves in a substantially transverse direction across a region of the ground.

Abstract: Systems and methods for aerial survey image capture are disclosed, including a system, comprising a camera system arranged to capture successive images of ground beneath a survey aircraft as the aircraft travels on a defined flight path, the camera system having associated camera parameters indicative of image capture characteristics of the camera system including defined image overlap between captured images; and, a camera parameter modifier arranged to produce at least one modified camera system parameter in response to an indication of a change in at least one navigation parameter of the aircraft, the modified camera system parameter modifying at least one characteristic of image capture by the camera system so as to substantially maintain the defined image overlap between captured images and thereby at least partially compensate for a change in survey efficiency when the changed navigation parameter is used to navigate the aircraft without modifying the defined flight path.

Abstract: An aerial survey image capture system for a survey aircraft is disclosed. The system comprises a camera system arranged to capture successive images of ground beneath a survey aircraft. The camera system has associated camera parameters, and a loss of separation (LOS) avoidance system for a survey aircraft. The LOS avoidance system is arranged to determine a predicted closest point of approach (CPA) distance between the survey aircraft and the nearby aircraft based on their locations and movements, compare the CPA distance with a defined minimum separation distance corresponding to a LOS, and determine an estimate for at least one navigation parameter of the survey aircraft required for the CPA distance to remain above the defined minimum separation distance. The system is further arranged to modify camera system parameters so as to at least partially compensate for a change in survey efficiency when the estimated at least one navigation parameter is used to navigate the survey aircraft.
