Abstract: A method for controlling a movable object includes obtaining current location information of an obstacle while the movable object tracks a target, determining whether the obstacle is located in a reactive region relative to the movable object based on the current location information of the obstacle. In response to determining that the obstacle is located in the reactive region, the method further includes determining, based on the current location information of the obstacle, whether the obstacle is located in a first sub-region or a second sub-region of the reactive region, where an area of the second sub-region is smaller than an area of the first sub-region; in response to determining that the obstacle is located in the first sub-region, reducing an acceleration of the movable object; and in response to determining that the obstacle is located in the second sub-region, reducing a velocity of the movable object.

Abstract: A method is provided for controlling flight of an aircraft carrying an imaging device. The imaging device is mounted at a gimbal. The method includes in response to receiving a triggering operation that triggers the aircraft to operate in an image control mode, obtaining an environment image captured by the imaging device, recognizing a gesture of a target user in the environment image, and in response to recognizing that the gesture of the target user is a start-flight gesture, generating a takeoff control command to control the aircraft to take off. Obtaining the environment image includes after obtaining the triggering operation, controlling the gimbal to rotate to control the imaging device to scan and photograph in a predetermined photographing range, and obtaining the environment image including a characteristic part of the target user that is captured by the imaging device through scanning and photographing in the predetermined photographing range.

Abstract: A method for controlling a movable object is provided. A user input that includes a first parameter corresponding to a first coordinate system is received and an operation mode is determined. In response to determining the operation mode being a first operation mode, a second parameter corresponding to a second coordinate system is generated and the movable object is controlled to move based on the second parameter. In response to determining the operation mode being a second operation mode, the first parameter is translated to a third parameter corresponding to the second coordinate system and the movable object is controlled to move based on the third parameter.
