[0052] S51, a calculation unit calculates a user's mood index according to the user data;

[0053] Specifically, the mood index can be calculated according to the following formula:

[0054]

[0055] Wherein, XQZB is a mood index used to characterize the user's mood, V is a voice parameter, and the voice parameter is obtained by a voice data analysis unit. When the voice data analysis unit analyzes that the user's emotion is negative, the voice parameter is set to -1, and when the user's emotion is positive, the voice parameter is set to 1. Voice is a voice index used to characterize the user's excitement. The larger the index value, the more excited the user's voice is. LV is the user's average heart rate during the data collection process, lv is the reference heart rate in a calm state, and the value is generally set to 55. e is a natural constant, A is the number of moments experienced during the collection process, t is the time experienced at each collection moment, and LV a is the heart rate detected at the ath moment, LV a-1 is the heart rate detected at the a-1th moment, SPO is the user's average blood oxygen saturation during the collection process, GSR is the skin conductance parameter, the larger the skin conductance parameter is, the more excited the user is, when the acquired skin conductance is greater than 0 and less than or equal to 3, the skin conductance parameter is set to 1, when the acquired skin conductance range is greater than 3 and less than or equal to 7, the skin conductance parameter is set to 1.5, when the acquired skin conductance range is greater than 7, the skin conductance parameter is set to 2.

[0056] F is the average frequency of the spectrum of the user's input speech, T is the total duration of the user's input speech, and F(t) is the frequency of the user's input speech at time t.

[0057] Specifically, the sound data analysis unit determines whether the user's emotion is positive or negative by using a speech data set (such as EMO-DB, IEMOCAP) marked with emotion tags.

[0058] like Figure 4 As shown, Figure 4 Assumption When the value of is 1000, the relationship between the average frequency of the spectrum of the user's input voice and the total duration of the user's input voice and the sound index is shown in the figure.

[0059] The following is the code for calculating the mood index:

[0060]

[0061]

[0062] S52: The judging unit judges the user's mood type according to the user's mood index.

[0063] Specifically, when the value of XQZB is less than 0, the user's mood is considered to be negative; when the value of XQZB is between 0 and 1.5, the user's mood is considered to be calm; when the value of XQZB is between 1.5 and 2.5, the user's mood is considered to be happy; and when the value of XQZB is above 2.5, the user's mood is considered to be excited.

[0064] S53, the night tour route matching unit selects a night tour location suitable for the user according to the user's mood type, and generates a recommended night tour route according to the obtained night tour location.

[0065] Specifically, when the user is in a negative or calm mood, the recommended night tour locations may be relatively quiet places such as river banks and natural parks; when the user is in a happy mood, the recommended night tour locations may be pedestrian streets or squares; when the user is in an excited mood, the recommended night tour locations may be night tour event sites; the night tour route matching unit obtains the shortest path that passes through all night tour locations as the recommended night tour route through the shortest path algorithm.

[0066] S54, the command generation unit generates corresponding image commands according to the generated night tour route and sends them to the VR display module.

[0067] Specifically, the command generation unit encodes the route data into instructions according to a unified image command protocol, the VR display module decodes the instructions according to the image command protocol and generates special effects for guiding the route on the three-dimensional map through the scene generation unit, thereby displaying the recommended night tour route on the VR display module.

[0068] The beneficial effects of this solution are: 1. By using VR technology to generate night tour scenes, it is beneficial for users to experience activities at different night tour locations from a distance, thereby stimulating users' enthusiasm for participating in activities. At the same time, using VR technology to reproduce night tour locations is more intuitive than directly displaying images of night tour locations, avoiding unclear images caused by shooting at night.

[0069] 2. By calculating the user's mood index to judge the user's mood and recommending night tour routes based on the user's mood, it is helpful to meet the user's night tour needs, improve the user's night tour experience, and improve the humanization of the system.

[0070] Embodiment 2: This embodiment should be understood to include all the features of any of the above embodiments, and further improve on the basis thereof, and also includes a night tour location classification method for classifying different night tour locations and matching them with different types of user moods. The central processing module also includes a night tour location analysis unit, which is used to perform image recognition on the captured images and analyze the liveliness index of the night tour locations. The classification method is implemented by the following steps:

[0071] The lively index of different night tour locations at a certain time is calculated according to the following formula:

[0072]

[0073] Among them, RNZB is the busyness index. The larger the index, the more busy the night tour location is. R is the floor space of the night tour location where people can stand. This floor space is the inherent floor space of the building and can be obtained in advance by technicians in this field based on architectural drawings or maps. num is the current number of people at the night tour location. r is the estimated floor space per person. This value can be set to 0.25m 2 , D max is the maximum decibel value ever detected at the night tour site, D ain is the minimum decibel value ever detected at the night tour location, D is the current decibel value detected at the night tour location, LIGHT is the light index. The larger the index, the more lively the atmosphere of the night tour location, B is the number of landscapes included in the night tour location, C is the number of landscapes included in the night tour location, and b is the landscape weight of the bth landscape at the night tour location, CS b is the area occupied by the landscape weight of the bth landscape at the night tour location; P is the number of images taken at the night tour location, L is the number of color types of the lights at the night tour location, PX pl Q is the ratio of the number of pixels containing the lth type of light in the pth captured image of the night tour location to the total number of pixels in the image, l is the liveliness coefficient of the lth type of light.

[0074] The following are the liveliness coefficients corresponding to various colors: mixed colors 1.7, red 1.5, orange 1.3, yellow 1.1, white 1.0, purple 0.8, green 0.7, blue 0.5.

[0075] Specifically, when there is only one captured image:

[0076]

[0077] Among them, LIGHT is the lighting index, L is the number of colors of the lights at the night tour location, and PX l For PX pl Q is the ratio of the number of pixels containing the lth light in the image taken at the night tour location to the total number of pixels in the image, l is the liveliness coefficient of the lth type of light.

[0078] Specifically, different colors can be distinguished by the HSV hue range.

[0079] Specifically, the landscape weights of different landscapes are set between 0 and 1 by technical personnel in this field based on experience. The more lively the atmosphere of the landscape, the greater its landscape weight. For example, landscapes can be classified into natural scenery and man-made objects. The landscape weight of natural scenery can be set to 0.4, and the landscape weight of man-made objects can be set to 0.8.

[0080] Specifically, when the value of the liveliness index is less than 0.3, the night tour location is a recommended night tour location for users with a negative or calm mood; when the value of the liveliness index is greater than or equal to 0.3 and less than or equal to 0.6, the night tour location is a recommended night tour location for users with a happy mood; when the value of the liveliness index is greater than 0.6, the night tour location is a recommended night tour location for users with an excited mood.

[0081] The beneficial effects of this embodiment are as follows: by setting a liveliness index to judge the liveliness of different night tour locations, it is helpful to recommend different night tour locations to users with different moods according to the liveliness, and it is helpful to distinguish the liveliness of the same type of night tour locations, so as to provide users with more humane recommendations.

[0082] The above disclosed contents are only preferred feasible embodiments of the present invention, and do not limit the protection scope of the present invention. Therefore, all equivalent technical changes made by using the contents of the present invention specification and drawings are included in the protection scope of the present invention. In addition, the elements therein can be updated with the development of technology. The above units are only examples.
