    摘要: 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.

    摘要: Systems, methods, and devices are provided for controlling a movable object using multiple sensors. In one aspect, a method for determining initialization information for a movable object comprises: detecting, with aid of one or more processors, that the movable object has started operating; receiving, at the one or more processors, inertial data from at least one inertial sensor carried by the movable object; receiving, at the one or more processors, image data from at least two image sensors carried by the movable object; and determining, with aid of the one or more processors, the initialization information for the movable object based on the inertial data and the image data, wherein the initialization information one or more of a position of the movable object, a velocity of the movable object, or an orientation of the movable object relative to a gravity direction when the movable object started operating.

    摘要: 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 is provided. The method can comprise: receiving initial values for the one or more extrinsic parameters, wherein the one or more extrinsic parameters comprise spatial relationships between at least two image sensors carried by the movable object; receiving inertial data from at least one inertial sensor carried by the movable object during the operation of the movable object; receiving image data from the at least two image sensors carried by the movable object during the operation of the movable object; and determining estimated values for the one or more extrinsic parameters based on the initial values, the inertial data, and the image data using an iterative optimization algorithm during the operation of the movable object.
