AI Technical Summary

Problems solved by technology

These methods are cumbersome and difficult to detect the vestibular function quickly and easily. At the same time, dizziness, nausea and other discomfort symptoms are easily produced during the detection process, which increases the pain of the patient.
On the other hand, the relevant test instruments not only require a large space for installation, are not easy to move after installation, and have limited use scenarios, but also have high cost and maintenance costs, which will increase the medical burden of patients

Embodiment 1

[0044] In one or more embodiments, a system for detecting vestibular dysfunction based on an inertial sensor is disclosed, which specifically includes:

[0045] 1. The data collection module is configured to collect the human body posture data of the subject in different walking modes.

[0046] Specifically, the data acquisition module uses an inertial sensor Mini IMU AHRS, including a three-axis accelerometer, a three-axis gyroscope, and a three-axis magnetometer. The inertial sensor is fixed on the head by a belt. The specific wearing position is as follows: figure 2 shown;

[0047] 2. The data transmission module is configured to transmit the collected human posture data to the data processing terminal;

[0048] Specifically, the data collected by the inertial sensor is wirelessly transmitted to the computer terminal through Bluetooth. Of course, the data transmission method is not limited to Bluetooth transmission, and other data transmission methods can also be used, su...

Embodiment 2

[0156] In one or more embodiments, a terminal device is disclosed, including a server, the server includes a memory, a processor, and a computer program stored on the memory and operable on the processor, refer to figure 1 , the processor implements the following process when executing the program:

[0157] Receive the collected human posture data of the subject under different walking styles;

[0158] preprocessing the data;

[0159] Perform feature extraction on the collected human posture data;

[0160] Use the random forest method and mutual information method to screen the extracted features to remove redundant and irrelevant features;

[0161] Input the extracted features into the trained vestibular function state recognition model, and output the vestibular function state recognition result.

Abstract

The invention discloses a vestibular dysfunction detection system based on an inertial sensor. The system comprises a data acquisition module, a data transmission module, a feature extraction module and a vestibular function state recognition module, wherein the data acquisition module is configured to acquire human body posture data of a subject in different walking modes through the sensor; thedata transmission module is configured to transmit the acquired human body posture data to the feature extraction module; the feature extraction module is configured to be used for performing featureextraction on the acquired human body posture data; and the vestibular function state recognition module is configured to be used for inputting extracted features into a trained vestibular function state recognition model and outputting a vestibular function state recognition result. The vestibular function can be detected quickly and conveniently without being limited by a detection site, discomfort symptoms such as dizziness and nausea of a patient in the detection process are reduced, and the detection cost of the patient is reduced.

Description

technical field [0001] The invention relates to the technical field of vestibular function detection, in particular to a vestibular dysfunction detection system based on an inertial sensor. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Vertigo is the third major clinical symptom after fever and headache. It is a complex syndrome between otolaryngology and neurology. [0004] With the aging of the population and the acceleration of the pace of life, the stress of work, the pressure of competition, and the increase in stimulating factors such as vibration, electromagnetic, radiation waves, and chemical substances in the environment, the vertigo has a tendency to increase year by year. Vestibular dysfunction is one of the main causes of vertigo, so the detection of vestibular function is particularly important. [0005] The vestibule is t...
