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: 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.

Abstract: A thermal management device for a battery pack 104 of an UAV is disclosed. The thermal management device 100 comprises an insulating enclosure 102 that is made of a material comprising at least an EPP foam for enclosing the battery pack 104, and one or more heating coils 110. The heating coils 110 are electrically powered from an external power source 112 for pre-heating the insulating enclosure 102 to a predefined temperature before flight of the UAV. The EPP foam of the insulating enclosure 102 provides high thermal insulation for retaining the heat of the insulating enclosure 102 for heating the battery pack 104 and maintaining the temperature of the battery pack 104 above a threshold temperature when the UAV flies in a sub-zero ambience temperature. The insulating enclosure 102 with the one or more heating coils 110 are configured to provide uniform heat distribution across the battery pack 104.

Abstract: The present disclosure relates to a system and method for executing safe-return of an Unmanned Aerial Vehicle (UAV) moving along a path having a plurality of communication waypoints in the event of a communication failure. In an aspect, the proposed method can include the steps of detecting, at the UAV, a communication failure; enabling the UAV to return to last healthy communication waypoint location; and based on status of the communication failure, enabling the UAV to return to its home location.

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 rotors 108 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 arms 110 are oriented parallel to central frame 104, and a storage position in which arms 110 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 maneuvering UAV for yaw and a secondary roll response. UAV includes two landing gears 106 attached to each end of central frame.
