Title:
Sensor fusion using inertia and an imaging sensor
Document Type and Number:
Japanese Patent JP6262865
Kind Code:
B2
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 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.
