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 device for self-balancing a rotating part, such as a propeller, along a given axis is disclosed. The propeller 102 coupled to a drive shaft with freedom for linear movement along longitudinal axis L-L; at least one pair of levers 614/616, comprising a first lever 614-1/616-1 and a second lever 614-2/616-2, that are pivotally mounted on mounting plate 606 at two diametrically opposite points 618; and at least one pair of weights 622 fixed at external ends of the levers 614/616. inner ends of levers 614/616 are operatively coupled to the propeller 102 such that when propeller 102 undergoes a linear movement in any direction along the longitudinal axis L-L due to unbalance, inner ends of levers are moved to cause the weights 622 to move to provide a balancing force to neutralize the unbalance in the propeller. An embodiment with only one pair of levers is also disclosed.

Abstract: The present disclosure pertains to a multi-rotor unmanned aerial vehicle (UAV). Aspects of the present disclosure provide a UAV that includes at least four arms, each configured with a co-axial pair of contra rotating propellers, wherein each propeller has capability of rotating reversibly with associated reversal of direction of thrust, and an autopilot control system that controls rotational direction and speed of the at least four co-axial pairs of propellers to maintain yaw stability, roll stability and pitch stability of the UAV, wherein in an event of failure of any one co-axial pair out of the at least four co-axial pairs of propellers, the autopilot control system reverses direction of rotation and thereby direction of thrust of at least one propeller of any functional pair.

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 translation: 本公开的实施例涉及用于固定翼UAV中的有效载荷的安装在腹部上的回缩机构。 可伸缩有效载荷可以是一个两轴相机系统，设计用于安装在飞机机身横截面内。 所公开的收缩机构是伺服驱动的直接连杆机构，其被配置为在有效载荷的缩回/收起位置和收起位置之间驱动有效载荷。 通过使有效载荷围绕水平轴线枢转地移动来预测位置。 缩回机构机械锁定在缩回位置和伸出位置，并且只有在伺服驱动时才能移动，从而防止由惯性或重力引起的任何意外移动。 收缩机构还包括弹簧，以抵抗有效负载的平稳下降的重力偏置有效载荷，以及当有效载荷移动到展开位置时关闭开口的滑动挡板。
