Embodiment Construction

[0060] This specific embodiment discloses a behavior recognition method based on a binary sensor, such as figure 1 shown, including the following steps:

[0061] S1: Preprocessing the data collected by the binary sensor to obtain the preprocessed binary sensor data;

[0062] S2: Segment processing the preprocessed binary sensor data obtained in step S1 based on space constraints and time constraints, to obtain segmented binary sensor data;

[0063] S3: Mapping and converting the segmented binary sensor data obtained in step S2 into a one-dimensional character string, and processing the one-dimensional character string to obtain a behavior pattern candidate set;

[0064] S4: Identify a specific behavior pattern from the behavior pattern candidate set obtained in step S3.

[0065] In step S1, the preprocessing process is: filtering invalid data in the data collected by the binary sensor; the invalid data meets at least one of the following three conditions:

Abstract

The invention discloses a behavior recognition method based on a binary sensor, comprising the following steps: S1: preprocessing the data collected by the binary sensor to obtain preprocessed binary sensor data; S2: based on space constraints and time Constraints segment the preprocessed binary sensor data obtained in step S1 to obtain segmented binary sensor data; S3: map and convert the segmented binary sensor data obtained in step S2 into one-dimensional characters String, process the one-dimensional character string to obtain a behavior pattern candidate set; S4: identify a specific behavior pattern from the behavior pattern candidate set obtained in step S3. The invention also discloses a behavior recognition device based on a binary sensor and a computer storage medium. The invention is convenient to use, does not violate privacy, has high accuracy, low calculation complexity and low cost.

Description

technical field [0001] The invention relates to behavior recognition, in particular to behavior recognition of nursing homes or elderly people living alone. Background technique [0002] The prior art has disclosed an invention patent application with the application number 201310489096.8 and the invention title "A Method for Monitoring Dangerous Behaviors of the Elderly in Nursing Homes", in which a method based on the combination of target tracking and behavior recognition is proposed to monitor the activities of the elderly in nursing homes in their daily life. A program for monitoring and alerting the elderly of dangerous and abnormal behavior. However, this solution requires a large number of cameras to be placed in the home environment for all-round and multi-angle monitoring, which easily violates the privacy of the elderly. [0003] The prior art also discloses a monitoring method based on wearable sensors, but it needs to be worn every day, which is very inconvenie...
