1. A method for processing information, applied to a mobile device, comprising:

  • collecting, at a preset frequency, pieces of location information of a target object tracked by the mobile device, comprising;

    transmitting, by the mobile device, through an Ultra Wideband (UWB) unit of the mobile device, a signal to the target object at the preset frequency;

    receiving, by the mobile device, a reflected signal from a UWB beacon of the target object;

    calculating, by the mobile device, a relative distance between the mobile device and the target object based on a time of flight (TOF) according to a transmission time of the signal and a reception time of the reflected signal; and

    calculating, by the mobile device, a relative angle between the mobile device and the target object based on an angle of arrival (AOA) according to a transmission angle of the signal and an arrival angle of the signal reaching the target object;

    extracting a piece of location information meeting a first condition from the collected pieces of location information, and saving the extracted piece of location information in a queue of target waypoints, wherein each piece of location information in the queue of target waypoints is configured to describe a target waypoint, and the pieces of location information of the target waypoints saved in the queue of target waypoints are arranged in the chronological order for collecting the pieces of location information; and

    generating a corresponding control instruction according to the pieces of location information of the target waypoints saved in the queue of target waypoints, wherein the control instruction is configured to control the mobile device to move towards the respective target waypoints described in the queue of target waypoints in order.
