A method for controlling a UAV in an environment includes receiving first and second sensing signals from a vision sensor and a proximity sensor, respectively, coupled to the UAV. The first and second sensing signals include first and second depth information of the environment, respectively. The method further includes selecting the first and second sensing signals for generating first and second portions of an environmental map, respectively, based on a suitable criterion associated with distinct characteristics of various portions of the environment or distinct capabilities of the vision sensor and the proximity sensor, generating first and second sets of depth images for the first and second portions of the environmental map, respectively, based on the first and second sensing signals, respectively, combining the first and second sets of depth images to generate the environmental map; and effecting the UAV to navigate in the environment using the environmental map.

Multi-sensor environmental mapping

A method for controlling an unmanned aerial vehicle (UAV) includes receiving first sensor data relative to a first coordinate system and second sensor data relative to a second coordinate system from a first sensor and a second sensor, respectively. The first and second sensor data includes first and second obstacle occupancy information indicative of relative locations of a first and a second sets of obstacles in reference to the UAV in the first and second coordinate systems, respectively. The first and second sets of obstacles have at least a subset of obstacles in common. The method further includes converting the first and second sensor data into a single coordinate system using sensor calibration data to generate an obstacle occupancy grid map based on the first and second obstacle occupancy information, and effecting the UAV to navigate using the obstacle occupancy grid map to perform obstacle avoidance.

Systems and methods for controlling a movable object within an environment are provided. In one aspect, a method may comprise: determining, using at least one of a plurality of sensors carried by the movable object, an initial location of the movable object; generating a first signal to cause the movable object to navigate within the environment; receiving, using the at least one of the plurality of sensors, sensing data pertaining to the environment; generating, based on the sensing data, an environmental map representative of at least a portion of the environment; receiving an instruction to return to the initial location; and generating a second signal to cause the movable object to return to the initial location, based on the environmental map.
