WEARABLE DEVICE, DANGER WARNING SYSTEM AND METHOD

摘要

A wearable device detects movement data of a user. A camera of the wearable device captures a three-dimensional (3D) image of an area surrounding the user. A determination is made as to whether a dangerous object appears in the area by analyzing the 3D image. If a dangerous object appears in the area, the a dangerous object appears in the area determines a distance between the user and the dangerous object, and triggers an alarm device to send out an alarm, on condition that the distance between the user and the dangerous object falls within a preset alarm range and a movement direction of the user is approaching the dangerous object.
