A movable object control method includes obtaining attitude information of a handheld control device, determining control information of a movable object according to the attitude information of the handheld control device, and sending the control information of the movable object to a head-mounted device to enable the head-mounted device to display a mark on a display device of the head-mounted device according to the control information of the movable object. The mark indicates a moving direction of the movable object.

Unmanned aerial vehicle, control method and control system thereof, handheld control device, and head-mounted device

A system of determining a flight path for an aerial vehicle, includes a memory storing a program code, and a processor configured to execute the program code to identify, during a flight, an abnormal state occurring at a first location, in response to the abnormal state, control the aerial vehicle to fly along a first flight path from the first location to a first destination, after the aerial vehicle arrives at the first destination, evaluate a status of the aerial vehicle at the first destination to obtain an evaluation result, and based on the evaluation result, determine a second flight path of the aerial vehicle to a second destination. The first flight path is a reverse of a last flight path of the aerial vehicle before the aerial vehicle reaches the first location.

Flight path determination

A gimbal servo control method includes obtaining a predicted flight trajectory of an aircraft within a preset time period from a current time, and adjusting an attitude of a gimbal carried by the aircraft according a predicted velocity direction of the aircraft at a point of the predicted flight trajectory.

Gimbal servo control method and control device

A system includes a flight controller. The flight controller is configured to, in response to a first user interface receiving a first user input, generate a first control signal. The first control signal is configured to control an unmanned aerial vehicle (UAV) to effect an autonomous flight with a first flight parameter and a second flight parameter. In response to a second user interface, different from the first user interface, receiving a second user input, the flight controller is further configured to modify the first flight parameter to obtain a modified first flight parameter, generate a second control signal based on the modified first flight parameter and the second flight parameter, and control the UAV to operate based on the second control signal.

Systems and methods for adjusting UAV trajectory

A method of determining a flight path for an aerial vehicle, includes controlling the aerial vehicle to fly along a first route, identifying, during the flight along the first route and with aid of one or more processors, a change in a state of signal transmission occurring at a first location, in response to identifying the change, determining, by the one or more processors, a second location different from the first location, determining a second route to the second location, and controlling, by the one or more processors, the aerial vehicle to fly to and land at the second location. The change of the state of signal transmission indicates an abnormal state in a signal transmission between the aerial vehicle and a control device.

A method for controlling an unmanned aerial vehicle (UAV) includes receiving, by a processor of the UAV, a plurality of images captured by an imaging device coupled to the UAV, identifying, by the processor, a target in at least one image of the plurality of images, determining, by the processor, whether the target is a stationary target or a moving target based on analyzing the plurality of images, and automatically effecting, by the processor, movement of the UAV based on determining the target is the stationary target or the moving target.

Systems and methods for UAV interactive instructions and control

A method for controlling flight includes displaying, in a real-time manner, a picture photographed and sent by a photographing device carried by an aerial vehicle; determining a no-clicking area in the picture based on a position of an obstacle or a no-fly zone; receiving a click operation of a user on the picture; and controlling a flight of the aerial vehicle based on the click operation. Controlling the flight of the aerial vehicle based on the click operation includes invalidating the click operation in response to determining a click location of the click operation being in the no-clicking area; and controlling the flight of the aerial vehicle based on a position of the click location in response to determining the click location being not in the no-clicking area.

Method and device for controlling flight, control terminal, flight system and processor

A computer-implemented method for controlling an unmanned aerial vehicle (UAV) includes obtaining a first image captured by an imaging device carried by the UAV during a takeoff of the UAV from a target location, obtaining a second image from the imaging device in response to an indication to return to the target location, determining a spatial relationship between the UAV and the target location by comparing the first image and the second image, and controlling the UAV to approach the target location based at least in part on the spatial relationship.

Methods and system for vision-based landing

A method for controlling flight includes displaying prompt information in a picture received from an aerial vehicle, dividing the picture into at least two portions based on the prompt information, obtaining a location of a click operation on the picture, and controlling a flight direction of the aerial vehicle based on the location and the prompt information.

A system for controlling an unmanned aerial vehicle (UAV) includes a first user interface configured to receive a first user input and a second user interface configured to receive a second user input. The first user input provides one or more instructions to effect an autonomous flight of the UAV. The second user input provides one or more instructions to modify the autonomous flight of the UAV, The autonomous flight includes a flight towards a target.

A method for determining a target direction for a movable object includes providing an image on a computer-implemented display, obtaining a position of a selected point on the image in response to a user selecting the point on the image, and determining the target direction based on the position of the selected point on the image.

Systems and methods for UAV path planning and control

A system for using ultrasound to detect distance on mobile platform and methods for making and using same. The system includes an ultrasound transceiver that can transmit and/or receive ultrasound waves and determine distance from an object of interest using a time-of-flight of the ultrasound wave. The system is adapted to reduce noise by using a dynamic model of the mobile platform to set constraints on the possible location of a received ultrasound echo. A linear, constant-speed dynamic model can be used to set constraints. The system can further reduce noise by packetizing a received ultrasound waveform and filtering out noise according to height and width of the packets. The system likewise can remove dead zones in the ultrasound transceiver by subtracting an aftershock waveform from the received waveform. The systems and methods are suitable for ultrasound distance detection on any type of mobile platform, including unmanned aerial vehicles.
