Abstract

The invention discloses a human body abnormal posture detection method. The method comprises the following steps: S11, acquiring a target image; S12, detecting the regional position of a human body in the target image and the posture of the human body; S13, judging whether the human body posture is an abnormal posture or not; S15, if the abnormal posture exists, judging whether the abnormal posture is the abnormal posture of the same human body appearing for the first time or not; if the abnormal posture is the abnormal posture of the same human body appearing for the first time, entering the step S16, otherwise, entering the step S17; S16, storing an abnormal posture category corresponding to the abnormal posture of the human body, an abnormal frequency, a regional position of the human body in the target image and storage time as abnormal target data; S17, finding out the area with the maximum intersection ratio with the area position corresponding to the abnormal posture, and comparing the similarity of the areas; S18, judging whether the similarity exceeds a first preset threshold value or not; and S19, if the first preset threshold value is exceeded, generating abnormal posture early warning.

Description

technical field [0001] The invention relates to a method for detecting abnormal posture of a human body. Background technique [0002] At present, in the field of abnormal posture detection, such as fall detection, there are three main research directions: 1. Detection based on wearable device sensors 2. Detection based on environmental information of the Internet of Things 3. Detection based on intelligent monitoring technology. The method based on wearable devices may not be able to detect abnormal conditions due to wear or damage of the device or forgetting to wear it; methods based on environmental sensors (such as pressure, sound, vibration, etc.) are currently not very good due to deployment costs or detection accuracy. Application. Intelligent monitoring technology collects images through cameras, and then recognizes images, which not only has strong real-time performance, high accuracy rate, but also relatively low cost. Therefore, it is a better choice to realize a...
