Abstract: A computer-implemented method of controlling an aircraft during autonomous landing. The method includes using a computer for performing the following: applying image processing on an image captured by a camera on board the aircraft while approaching a runway for identifying in the image a touchdown point (TDP) of the runway; calculating a deviation, in image parameters, of the TDP relative to the center of the image; converting the deviation in image parameters to angular and distance deviation values based on predefined ratios; calculating an offset of the aircraft's position relative to a landing corridor ending at the identified TDP based on the calculated angular and distance deviation; and transmitting the calculated offset to an aircraft control system configured to provide instructions for controlling the aircraft; wherein the offset is used for controlling the aircraft for guiding the aircraft towards the landing corridor to enable landing.

Abstract: Videography of surfaces and improved positional control of unmanned aerial vehicles (UAV) are disclosed. Embodiments include a “panning” piloting scenario. The panning can include control parameters relative to a normal vector to a point P of a plane representing a surface, or relative to a direction of gravity and attributes of the surface. For example, the UAV can be programmed, or controlled, to “pan” about the point on the plane maintaining a certain distance therefrom while rotating about angles to the normal vector. Methods of estimating a surface include determining a plane including three non-collinear points of the surface. The plane determined can be relative to the direction of gravity, such as vertically parallel to gravity. A piloting routine can include piloting a UAV to various angles relative to the vector normal to the plane and distances to the location on the surface and/or point on the plane.

Abstract: The present disclosure discloses an obstacle avoidance method and apparatus and an unmanned aerial vehicle. The method includes: obtaining detection images of at least two different focal lengths from a camera apparatus; determining, according to the detection images of the at least two different focal lengths, that an obstacle exists in a detection area; and obtaining position information of the obstacle according to the detection images of the at least two different focal lengths. Because the camera apparatus performs a zooming operation quickly, it's no need to precisely obtain position and attitude information by using a Global Positioning System (GPS) and an onboard inertial device, which avoids measurement interference and a positioning error caused by the inertial device, thereby improves calculation precision.

Abstract: Aerial vehicles may be operated with discrete sets of propellers, which may be selected for a specific purpose or on a specific basis. The discrete sets of propellers may be operated separately or in tandem with one another, and at varying power levels. For example, a set of propellers may be selected to optimize the thrust, lift, maneuverability or efficiency of an aerial vehicle based on a position or other operational characteristic of the aerial vehicle, or an environmental condition encountered by the aerial vehicle. At least one of the propellers may be statically or dynamically imbalanced, such that the propeller emits a predetermined sound during operation. A balanced propeller may be specifically modified to cause the aerial vehicle to emit the predetermined sound by changing one or more parameters of the balanced propeller and causing the balanced propeller to be statically or dynamically imbalanced.

Abstract: A system and method for rapidly modifying flight mission plans for unmanned aerial vehicles (UAVs) is described. This includes a programming controller that requests the name of the existing flight mission in the UAV. When the requested name of the existing flight mission in the UAV is found to be the same name as that of the desired flight mission in the programming controller then the UAV is simply enabled by the programming controller to carry out the desired flight mission. When the requested name of the existing flight mission in the UAV is found not to be the same name as the modified flight mission in the programming controller then the programming controller creates and provides instructions to the UAV for rapidly updating the existing flight mission into the desired flight mission. These rapid updating instructions are similar to currently used ways of synchronizing personal computers in point-in-time procedures.
