Abstract: A method of generating a three-dimensional point cloud includes obtaining a plurality of image data sources through a plurality of sensors, and performing fusion processing according to the plurality of image data sources to obtain the three-dimensional point cloud.

Abstract: Systems, methods, and devices are provided for controlling a movable object using multiple sensors. In one aspect, a method for calibrating one or more extrinsic parameters of a movable object having a plurality of sensors in an initial configuration is provided. The method can comprise: detecting that the initial configuration of the plurality of sensors has been modified; receiving inertial data from at least one inertial sensor during operation of the movable object; receiving image data from at least two image sensors during the operation of the movable object; and estimating the one or more extrinsic parameters based on the inertial data and the image data in response to detecting that the initial configuration has been modified, wherein the one or more extrinsic parameters comprise spatial relationships between the plurality of sensors in the modified configuration.

Abstract: A navigation method includes obtaining a route mark in a three-dimensional map. The navigation method also includes generating a navigation route based on the route mark, the navigation route circumventing a specified object in the three-dimensional map. The navigation method further includes sending a motion instruction to a movable object based on the navigation route.

Abstract: A method for controlling movement of a moving object includes, based on a target object selecting operation, a center point of a target object range on a display interface and a target-object-range adjusting pressure for adjusting the target object range, determining the target object range in the display interface according to the center point of the target object range and the target-object-range adjusting pressure, and determining an image object in the target object range as a target object tracked by the moving object.

Abstract: An unmanned aerial vehicle (UAV) includes a detection device configured to generate a supplement demand signal in response to a need of the UAV for resource supplement, a wireless communication device configured to establish a wireless communication connection with at least one aerial platform and communicate with the at least one aerial platform in response to the supplement demand signal being generated, and a flight control device configured to determine a target aerial platform from the at least one aerial platform, generate a flight control signal based upon communication information of the target aerial platform received by the wireless communication device, and adjust a spatial distance between the UAV and the target aerial platform based upon the flight control signal to enable an airborne replenishment to the UAV by the target aerial platform.
