An unmanned aerial vehicle (UAV) is provided. The UAV includes a main body, a plurality of motors connected to the main body, each of the plurality of motors having a rotor blade, a plurality of ultrasonic sensors located at least one of the plurality of motors and the main body, and transmitting and receiving ultrasonic waves to and from a ground surface, and measuring distances from the ground surface, a gyro sensor disposed at the main body and maintaining the UAV in a horizontal state, and a controller disposed at the main body, detecting an unevenness of the ground surface based on the distances from the plurality of ultrasonic sensors to the ground surface, generating a control signal whether to land on the ground surface or not in response to the detection of the unevenness, and transmitting the control signal to the plurality of motors.

Unmanned aerial vehicle and a landing guidance method using the same

Methods and apparatus are described for drone collision avoidance that includes extracting first feature information from an image. The image is captured from a first camera oriented in a direction. Second feature information is received from an external source. The second feature information is extracted from a second image of the environment captured by a second camera oriented in the direction. The first feature information and the second feature information are matched. A second local frame of reference of the second feature information is transformed to a first local frame of reference of the first feature information to determine a location of the external source. If a collision with the external source will occur is determined based on the location of the external source and a current flight trajectory.

Vision-based cooperative collision avoidance

The invention discloses an unmanned aerial vehicle projection method and system. The unmanned aerial vehicle projection method comprises the steps of: carrying out communication connection on an unmanned aerial vehicle and a ground terminal; uploading multimedia information to the unmanned aerial vehicle by the ground terminal, and enabling the unmanned aerial vehicle to utilize an onboard projector to carry out projection playing. In the mode, according to the unmanned aerial vehicle projection method and system disclosed by the invention, words, images or videos or voice and the like uploaded to the unmanned aerial vehicle by the ground terminal can be displayed and played in real time, so that the unmanned aerial vehicle has projection and voice functions and has higher entertainment.

Unmanned aerial vehicle projection method and system

A method and system for capturing images of an asset using an unmanned aerial vehicle. The method includes acquiring structural information of the asset, acquiring surrounding information associated with the asset, analyzing the structural information and the surrounding information of the asset to define image capturing points for the unmanned aerial vehicle, and capturing the images of portions of the asset from the defined image capturing points. Moreover, each of the defined image capturing points allows the unmanned aerial vehicle to capture an image of a portion of the asset with an even background.

Method and system for capturing images of asset using unmanned aerial vehicles

Methods and apparatus for drone collision avoidance. Processing circuitry of a drone extracts information from an encoded image captured by a detection device with a field view overlapping the encoded image. Based on the extracted information a determination is made whether a collision will occur on the flight trajectory of the drone with an external source. The flight trajectory of the drone is then altered to avoid a collision.

Projection-based cooperative collision avoidance

The embodiment of the invention provides an image projecting method based on an aircraft, an image projecting device based on the aircraft and the aircraft, wherein the method comprises the following steps of if an image projecting event on the aircraft is detected, regulating the position of the aircraft to a projectable position; and triggering an aircraft projecting module to project an image, wherein the step of regulating the position of the aircraft includes the process of regulating the position of the aircraft according to an image of an obstacle obtained in the projecting direction of the projecting module. When the method and the device are used, the aircraft can be combined with the projecting module such as a projector; the projecting position can be fast changed according to requirements only by controlling the flight of the aircraft; and the fast, convenient and flexible image projection is realized.

A method and device for aerial vehicle-based image projection, and an aerial vehicle are provided. The method comprises adjusting a position of the aerial vehicle to a projection-permitted position if an image projection event for the aerial vehicle is detected, triggering a projection module of the aerial vehicle to project an image. Adjusting the position of the aerial vehicle comprises adjusting the position of the aerial vehicle based on an obstacle image captured in a projecting direction of the projection module.

Method of aerial vehicle-based image projection, device and aerial vehicle

Provided are an image projection method and apparatus based on an aerial vehicle, and an aerial vehicle. The method comprises: if an image projection event of an aerial vehicle is detected, then adjusting a location of the aerial vehicle to a projectable location; and triggering an aerial vehicle projection module to project an image, wherein the adjusting the location of the aerial vehicle comprises: adjusting the location of the aerial vehicle according to the image of an obstacle acquired in a projection direction of the projection module. An aerial vehicle can be combined with a projection module, such as a projector, and only by controlling the flight of the aerial vehicle, a projection location can be changed rapidly according to requirements, and fast and flexible image projection is achieved.
