Specifically, as shown in fig. 4, the use method of the present device in combination with software for testing vertigo degree in the main control module is as follows: (of course, when in use, the equipment is not limited to the testing scene of vertigo degree, but also can be used for the scenes of performance tests in other aspects)

S1, acquiring and processing an initial state image of a user, specifically:

s11, acquiring an initial state image of a user through an image acquisition device 6;

s12, extracting auxiliary feature points and central feature points in the initial state image, and constructing a standard feature vector;

specifically, as shown in fig. 5, there are an auxiliary feature point and a central feature point, and the central skeleton point of the left or right shoulder is extracted as the auxiliary feature point, and the central point between the two shoulders is extracted as the central feature point;

s2, continuously acquiring and processing a user test state image after the user enters virtual reality, specifically:

s21, collecting a user test state image;

s22, extracting auxiliary characteristic points and central characteristic points in the image in the test state, judging whether the station positions in the initial state and the test state have displacement or not, if so, extracting station position offset, correcting the current auxiliary characteristic points and central characteristic points according to the station position offset, and constructing an offset characteristic vector;

otherwise, the offset feature vector is directly constructed according to the auxiliary feature points and the central feature point.

And, here, the standing position in the initial state and the standing position in the test state of the user are obtained through the sensing situation in the initial state and the sensing situation in the current state of each sensor 3, so as to obtain the standing position offset.

S3, comparing the initial state image of the user with the test state image, and outputting the vertigo degree according to the comparison result, which specifically comprises the following steps:

s31, fusing the offset characteristic vector and the standard characteristic vector, and recording an offset parameter of the offset characteristic vector; the offset parameter describes the degree of body imbalance swing, corresponding to the degree of vertigo of the user. The offset parameter may serve as an objective index quantifying the degree of body tilt, which in turn corresponds to the vertigo degree of the user, so the index is used to evaluate quantifying the vertigo degree of the user;

and S32, comparing the offset parameters with the standard values in the database, and generating a report containing the vertigo degree according to the comparison result.

The constant database stores standard values of different shift parameter ranges corresponding to different vertigo degrees of users with different characteristics, and extracts corresponding standard values for shift comparison according to the characteristics of the current user;

and the different characteristics of the user include gender, age group and height. As the present embodiment is directed to 6 to 18 years of age, each year as an age group characteristic; for ages 19 to 24, as an age group characteristic every two years; for 25 to 50 years, every five years as a segment of age characteristic; the ages of 51 to 60 are taken as a characteristic of one age group, and the ages over 61 are taken as a characteristic of one age group. By inquiring the vertigo feelings of large users and combining the measured deviation parameters, the different deviation parameter ranges under different age stages, different sexes and different vertigo degree feelings are counted out to be used as standard values. When the offset characteristic vector and the standard characteristic vector are fused, obtaining a position offset value of the central characteristic point in the test state compared with the central characteristic point in the initial state and an included angle between the offset characteristic vector and the standard characteristic vector; and calculating a product value of the sine value of the included angle and the standard characteristic vector, and taking the sum of the obtained position deviation value and the product value of half as a deviation parameter, wherein the unit of the parameter is centimeter. The shift parameter ranges for each vertigo class for men such as 25-30 years old are:

no dizziness, (-2, 4); mild vertigo, (-8, -2) and [4, 18); moderate vertigo, [ -14, -8] and [18,34 ]; severe vertigo is less than-14, or greater than 34.

Here, four levels are classified into no vertigo, mild degree, moderate degree and severe degree, and when the device is put into use, the device can also be classified into more levels, and the device is not limited herein.

Specifically, in step S22, the condition that at least a preset number of times, for example, 3 swings within 5 minutes, continuously occur within a preset time period is regarded as unbalanced tilt swing, and vertigo degree calculation is performed, otherwise, it is determined that the user is autonomously swinging, vertigo degree calculation is not performed, and measurement errors caused by the autonomous swinging of the user are eliminated. The wobble is a case where the offset eigenvector is offset from the standard eigenvector, and in order to avoid a slight fluctuation of the user himself, it is considered that the wobble occurs due to dizziness when the absolute value of the offset parameter is larger than a certain value.

Preferably, when the unbalance tilt and swing is judged to belong to, a plurality of offset feature vectors of a plurality of test state images in the period of time are obtained, and an offset parameter obtained by fusing the offset feature vector with the standard feature vector with the most serious swing can be directly selected as an offset parameter used for vertigo measurement. The offset parameters obtained by fusing each offset eigenvector with the standard eigenvector can also be used, at this time, if a plurality of offset parameters are in the vertigo degree of the same grade, the result is directly output, if the offset parameters do not belong to the same grade, the number of the covered offset parameters is sequentially judged from the highest grade to the lowest grade, when the number of the offset parameters covered by the highest grade is higher than the preset value, the highest grade is judged, otherwise, the grade is reduced until the number of the offset parameters covered by a certain grade is higher than the preset value, and the vertigo degree is judged to be in the corresponding grade. The preset value is determined according to factors such as the length of the preset time slot, and the like, the embodiment is determined by 3 times, if the deviation parameter of a 28-year-old man for 3 times is greater than 34 or less than-14, the man is determined to be severely dizzy, if the deviation parameter is only 2 times, the man is reduced by one grade, the man continues to check the number of deviation parameters of the man in the range of [ -14, -8] and [18,34], if the deviation parameter is greater than or equal to 3 times, the man is determined to be moderately dizzy, and if the deviation parameter is not greater than or equal to 3 times, the man is reduced by another grade.
