Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] Such as figure 2 As shown, the flow chart of the video monitoring method of the old people leaving the bed and in bed state of the present invention is provided, which is realized through the following steps:

[0025] a). Arrangement of cameras. Arrangement of cameras in the room of the elderly to be monitored. The installation position of the cameras is such that the collected pictures include the bed and the surrounding area of ​​the bed;

[0026] b). Obtain images of getting out of bed, collect video images for a period of time when the old man is getting out of bed, obtain images of the old man getting out of bed, randomly select some of the images in the image as training samples, and use the remaining images as training samples. test samples;

[0027] c). Normalization and annotation processing of images. First, normalize the images obta...

Abstract

The video monitoring method of the old people leaving the bed and being in the bed state of the present invention, a). Arranging the camera; b). Collecting the active images of the old people leaving the bed in bed to form training and test samples; c). Normalization and labeling of images Process and form the label file; d). Train the neural network; e). Use the test sample to calculate the accuracy of the deep neural network. If the accuracy is lower than the set threshold, increase the capacity of the training sample and retrain. If the accuracy is not If it is lower than the threshold, the training is completed; f). Bring the real-time monitoring image into the neural network, and calculate the overlap rate between the human body and the bed body to judge the state of the old man leaving the bed. The present invention utilizes the video image processing technology to monitor the situation of the old man getting out of bed and being in bed, and alarms the abnormal situation in the process of the old man getting out of bed, so as to prevent the old man from being out of bed for a long time to happen unexpected situations.

Description

technical field [0001] The present invention relates to a video monitoring method for the state of leaving the bed and being in bed of the elderly, and more specifically, relates to a method of using a trained deep neural network model to obtain the overlap rate of the human body and the bed to determine where the elderly are. A method for video monitoring of bed-exit and bed-in status of older adults. Background technique [0002] In recent years, the problem of population aging in my country has become more and more serious. With the increase of age, the responsiveness and physical functions of the elderly decline, and it is easy to have accidents in life. Most of the daily life needs other people to take care of them. Therefore, more and more Elderly people choose to live in nursing homes. [0003] At present, most elderly care institutions in my country are facing a shortage of nursing staff, and it is difficult for nursing staff to monitor the situation of the elderly l...
