Abstract: A method for capturing images of large target area using a single low FOV high resolution camera mounted on an Aerial Vehicle for 3D reconstruction is disclosed. The camera captures sets of images consisting of a nadir image a plurality of oblique images at predefined waypoints or as the Aerial Vehicle travels along a flight path. Oblique images are captured in two perpendicular directions by tilting camera about a single tilt axis at one time thereby preventing bidirectional distortion of objects in images. Further, first direction and second direction define a quadrant of area below the Aerial Vehicle. Oblique images along two perpendicular directions are captured either by using roll and pitch axes, or by using a single tilt axis and a pan axis of camera control mechanism wherein using pan axis the single tilt axis is reoriented in a perpendicular orientation to capture oblique images in perpendicular direction.

Abstract: The present disclosure relates to generating a single vertex list/point-cloud list of an object for rendering the object in different complexity levels. The generated single vertex list comprises a large number of points obtained from external surfaces of the real-time object for detailed 3D representation and the list is updated with new batches of received point cloud vertices. The points are rendered from the single vertex list based on the correlation between zoom level and point retention factor. A scene's zoom/scaling level is altered by changing the distance of a camera to the objects represented by the rendered point cloud.

Abstract: A fixed-wing VTOL hybrid UAV is disclosed comprising: a central frame 104; a pair of quick lockable fixed-wings 102 comprising right wing 102-2 and left wing 102-1 that lock with each other over the central frame; and four electrically operated rotors108 in downward facing configuration attached to fixed-wings with help of rotor-blade arms 110. Arms 110 are pivotally fixed to wings 102 so that arms 110 are movable between a working position in which arms110 are oriented parallel to central frame 104, and a storage position in which arms110 are aligned with wings 102. Central frame 104 is a thin rod and works as fuselage. Drivers and control modules are fitted in wings 102. UAV includes rudders attached to arms at 45 degrees for manoeuvring UAV for yaw and a secondary roll response. UAV includes two landing gears 106 attached to each end of central frame.

Abstract: A multi-rotor Aerial Vehicle with least rotors/propellers and having single arm failure redundancy is disclosed. The AV comprises at least five arms with at least one arm having a co-axial pair of contra rotating rotors/propellers. To maintain yaw stability under normal conditions, half of rotors/propellers are rotated in one direction and other half in opposite direction. In the event of failure of any one of the rotors/propellers located adjacent to the pair of contra rotating rotors/propellers, the one propeller/rotor out of the contra rotating rotor/propeller that is rotating opposite to the failed rotor/propeller is shut off. In the event of failure of a rotor/propeller belonging to contra rotating rotors/propellers, other rotor/propeller of the pair is shut off. In the event of failure of any one of rotors/propellers not adjacent to contra rotating rotors/propellers, the RPMs of other rotors/propellers is adjusted to maintain stability and navigate the Aerial Vehicle.

Abstract: Embodiments of the present disclosure relate to a belly-mounted retraction mechanism for a payload in a fixed wing UAV. The retractable payload can be a two-axis camera system designed to fit inside the aircraft fuselage cross section. The disclosed retraction mechanism is a servo driven direct link mechanism configured to drive the payload between its retracted/stowed position & projected position by pivotally moving the payload about a horizontal axis. The retraction mechanism gets mechanically locked in retracted and projected positions and can only be moved when driven by the servo thus preventing any unintended movements due to inertia or gravitational forces. The retraction mechanism further comprises a spring to bias the payload against gravitational force for smooth descent of the payload and a slider flap to close the opening when the payload is moved to deployed position.

Abstract: A method for capturing images of large target area using a single camera configured with an aerial vehicle (AV) for reconstructing a high-resolution image is disclosed including the steps of moving the AV over the area of interest along a straight path; capturing a first set of images of an area down below by pointing an optical axis of the camera towards a first side of the straight path such that the optical axis makes a first predefined angle with vertical; and capturing a second set of images of the area down below by pointing the optical axis of the camera towards a second side of the straight path such that the optical axis makes a second predefined angle with respect to the vertical. Side overlap between the first and second set of images is optimized to account for error in camera movement.
