Fall detection system and method

Abstract

The invention relates to a fall detection system and method. A depth detection device detects an object in a detection range, the depth detection device generates depth data of the object, a fall identification device receives the depth data and generates a height change value according to the depth data before and after, the fall identification device determines that the object has a fall sign after confirming that the height change value accords with a preset fall value, the fall identification device determines that the object has the fall sign when the area information of the object calculated according to the depth data after the fall sign accords with the preset fall value, and the fall identification device determines that the object falls down when determining the object has a moving sign in the depth data with the fall sign and the down sign.

Description

technical field [0001] The present invention relates to a fall detection system and its method, in particular to a fall recognition device that utilizes height information, area information, and depth data generated by a depth detection device to detect an object, and a system and method for judging whether the object has fallen. Background technique [0002] In recent years, the fertility rate has gradually declined, which has made the population structure tend to be aging. At the same time, many of these aging populations have no care for their offspring, which has greatly increased the proportion of the population living alone. These people need to use other methods to provide appropriate care. Home care, in order to avoid accidents and regrets that cannot be given in time for first aid. [0003] At present, in response to the aforementioned problems, many companies have proposed various home care products. For example, in terms of wearable devices, Apple’s smart watch is...
