The invention belongs to the technical field of
image analysis, and discloses an old people health
state prediction and alarm method based on AI
image analysis, and the method comprises the steps: obtaining a depth image, a
color image and a pressure image of an activity environment of old people, carrying out the combined analysis of the depth image and the pressure image, recognizing a
terrain semantic region in a monitoring region, and carrying out the prediction of the health state of the old people; and carrying out dynamic segmentation on the
gait contour of the old people. And the
terrain gait coupling degree is calculated by analyzing the depth change characteristics and the motion period characteristics of the
gait sub-regions, so that the abnormal gait sub-regions are screened out. And for the abnormal regions, the
terrain gait
coupling degree, the dynamic texture features of the
color image and the pressure distribution features of the pressure image are fused, and a cross-
modal health risk vector is constructed. Based on the vector, the health state of the old people is accurately predicted, and a corresponding
alarm signal is generated. According to the invention, precise evaluation and timely early warning of the health state of the old people are realized, and intelligent guarantee is provided for the home safety of the old people.
