Abstract: A magnetic sensor calibration method includes obtaining a relative movement parameter between a mobile magnetic member of a mobile platform and a magnetic sensor of the mobile platform during movement of the mobile magnetic member and calibrating sensor data output by the magnetic sensor according to the relative movement parameter. The mobile magnetic member and the magnetic sensor are not rigidly connected.

Abstract: A method for tracking a target object using a detection apparatus includes calculating movement state information of the target object with respect to the detection apparatus according to one or more monitored images, calculating a distance between the target object and the detection apparatus, in response to the distance being not greater than a pre-set distance threshold, estimating, based on first state information including the movement state information, second state information of the target object after a pre-set delay duration, and performing an operation with respect to the target object according to the estimated second state information.

Abstract: A method for adjusting feedback of a remote controller includes obtaining wind data that corresponds to wind incident on a movable object controlled by the remote controller, mapping the wind data to one or more axes of an input device of the remote controller that correspond to one or more axes of the movable object, respectively, and adjusting a feedback of the input device with respect to one of the one or more axes of the input device based at least in part on the wind data mapped to the one or more axes of the input device. The wind data includes wind velocity data along the one or more axes of the movable object.

Abstract: A method for detecting a target object includes: identifying a target object in a monitored region, and calculating first state information of the target object with respect to this detection apparatus; estimating second state information of the target object after a pre-set delay duration value according to the first state information; and performing a processing operation on the target object according to the estimated second state information. The present disclosure can quickly and accurately complete the tracking and state estimation of a target object, which adds new functions and satisfies automation and intelligence requirements of a user for object tracking and movement state estimation.
