Abstract: A method for controlling palm landing of an unmanned aerial vehicle (“UAV”) includes detecting a flight status of the UAV under a predetermined condition. The method also includes controlling the UAV to land on a palm of a user when the flight status is a hover state and when the palm is located under the UAV.

Abstract: An image processing device acquires at least two first images and at least two second images, where a resolution of the at least two first images is a first resolution, a resolution of the at least two second images is a second resolution, and the second resolution is lower than the first resolution. By using the at least two first images and the at least two second images, the image processing device respectively determines a first depth map corresponding to the at least two first images under a limit of a first disparity threshold, and a second depth map corresponding to the at least two second images under a limit of a second disparity threshold, where the second disparity threshold is greater than the first disparity threshold. The image processing device then combines the determined first depth map with the second depth map to generate a combined depth map.

Abstract: A computer-implemented method includes detecting a change in a spatial configuration of a plurality of sensors coupled to an unmanned aerial vehicle (UAV) based on a first set of sensor data from a plurality of sensors, generating one or more calibration instructions to cause the UAV to move along a predetermined pattern in response to detecting the change in the spatial configuration, and determining a subsequent spatial configuration of the plurality of sensors based at least in part on a second set of sensor data from the plurality of sensors. The second set of sensor data is collected by the plurality of sensors when the UAV is moving along the predetermined pattern.

Abstract: A method for determining position of a target includes determining at least two measurement points of the target, obtaining vector data of at least two direction vectors based on an imaging position of the target on an imaging system and parameter data of the imaging system, and determining a distance between the target and the imaging system according to the vector data and a current vertical height of the imaging system. Each of the at least two direction vectors is a vector from the imaging system to a corresponding one of the at least two measurement points.
