Embodiment

[0050] This embodiment provides a wrestling detection method based on human body posture and orientation estimation. The entire flow chart of the detection method is as follows figure 1 As shown, the system structure diagram is as follows figure 2 shown. The sensor integration device used in this embodiment integrates a three-axis acceleration sensor, a three-axis angular velocity sensor, a magnetometer, a calibrator and a Bluetooth module, and is packaged into a self-contained small device (36mm×51mm×15mm). The construction of implementing actions in this embodiment is based on the real scene of old people wrestling in reality, including wrestling actions and daily actions. Wrestling right. The actions designed in this embodiment are shown in Table 1.

[0051] At the same time, the sensor integration device in this embodiment is respectively worn by the user on three parts of the shoulder, waist and foot, and multiple sets of experiments are carried out to verify the robu...

Abstract

The invention discloses a wrestling detection method based on human body posture and orientation estimation. The method comprises the following steps that a mobile phone terminal receives human body motion data measured by sensor integrated equipment and carries out input correction; human body data is fused and interference terms are removed through Kalman filtering; a human body posture angle isestimated according to the human body motion data; and wrestling detection and judgment are performed according to the human body motion data and the human body posture angle. According to the invention, the detection method is integrated on the mobile phone terminal, a user only needs to wear a piece of a portable sensor integrated device, and the mobile phone terminal downloads a matched client, so that robust wrestling detection can be realized. When a user tumbles, the mobile phone terminal can give an alarm in time. The user can wear the sensor integrated device on any part such as a trunk or legs, and when the sensor integrated device is worn on the waist and the legs, the accuracy of wrestling detection reaches 100%.

Description

technical field [0001] The invention belongs to the technical field of wrestling detection, and in particular relates to a wrestling detection method based on human body posture and orientation estimation. Background technique [0002] For the elderly and patients with inconvenient legs and feet, a careless fall will cause huge injuries to them, and even lead to disabling fractures in severe cases. If a fall occurs, timely assistance cannot be obtained, which will cause more serious secondary injuries and even endanger life safety. Therefore, many wrestling detection methods have been proposed in recent years, so that when an accident occurs, rescuers can arrive in time to avoid subsequent injuries. [0003] In the patent that Chinese Publication No. is CN110111532A, a kind of old people's walking reminder and wrestling alarm device are disclosed. The principle of this method is very simple, and the function of wrestling judgment can be realized through mercury tubes and c...
