Whether waste heat value simultaneously judges whether user is modified preliminary guidance path section, continue to judge user to preliminary when meeting
Guidance path section is modified；When user is modified preliminary guidance path section, according to the user's choice to preliminary navigation
Route segment is modified acquisition guidance path；Obtain the three-dimensional information of the building on guidance path.
Optionally, it generates guidance path according to navigation starting point, endpoint information and can be calculated by the matching based on topological structure
Method generates guidance path, can also generate guidance path based on the matching algorithm of classification of road.
S3, the scene mode selected according to user, sight spot terrestrial reference all under the scene mode is selected by mapping table
Threedimensional model is as Candidate Set.
S4, according to the length of guidance path, the three-dimensional information of building screened from Candidate Set with the length of guidance path,
The threedimensional model of the matched sight spot terrestrial reference of the three-dimensional information of building.
S5, the three-dimensional information of the building on the threedimensional model and guidance path of sight spot terrestrial reference is carried out after virtual reality fusion with
Guidance path is shown in VR equipment.
VR equipment can be wearable device, such as virtual implementing helmet etc..
S6, acquisition user select the label of modified guidance path section, and improve the weight of the label；In user individual
The corresponding weight of label of the guidance path section is updated in database.User selects the label of modified guidance path section, can be with
Being considered as user selects the weight of the label of modified guidance path section higher.
The scene mode that S7, the navigation starting point, endpoint information and user for obtaining user's input again select, and weigh according to this
Multiple step S2 to step S6.
What the embodiment of the present invention considered is not only shortest path, and possible user is used for the purpose of walking to some sometimes
Place, but be not especially take notice of the time, therefore can select through the embodiment of the present invention it is some can loosen for user stop
The mode of rest, personalization level are higher.
Optionally, in the walking navigation method of the virtual reality of the health type described in the embodiment of the present invention, the step
S1 includes:
The characteristic information of each sight spot terrestrial reference is obtained in advance, and characteristic information includes the classification information of sight spot terrestrial reference, geographical letter
Breath, natural quality information；The threedimensional model of sight spot terrestrial reference is established according to geography information.Optionally, the classification information of sight spot terrestrial reference
Such as by whether being that artificial structure divides；Geography information includes the letter such as height, shared area, width of sight spot terrestrial reference
Breath；Natural quality information includes being divided by warm tones or cool tone, according to clamour or quiet divide etc..Above point
Class can be configured independently.
Default scene mode generates the three-dimensional mould of sight spot terrestrial reference according to the classification information of sight spot terrestrial reference, natural quality information
The mapping table of type and scene mode information；Classification information, the natural quality information of scene mode and sight spot terrestrial reference are in mapping table
One-to-many relationship.
The threedimensional model of sight spot terrestrial reference, mapping table are stored in scene data library；
The corresponding label in various sections is preset, and weight is set to each label；By the corresponding label in section and it is somebody's turn to do
The weight storage of label is in user individual database.
Optionally, in the walking navigation method of the virtual reality of the health type described in the embodiment of the present invention, the step

Judge whether the distance of preliminary guidance path meets the waste heat value of consumption user itself setting；When being unsatisfactory for certainly
The dynamic one or more preliminary guidance path sections of replacement are until meeting the waste heat value of consumption user itself setting and judging user
Whether preliminary guidance path section is modified, continues to judge whether user is modified preliminary guidance path section when meeting；
If there is the instruction that user is modified preliminary guidance path section, then the selected alternative navigation road of user is used
Diameter section replaces corresponding preliminary guidance path section, and generates guidance path；If there is no user to preliminary guidance path section
The instruction being modified, then directly generate guidance path.Directly generating guidance path is to be determined as using by preliminary guidance path
The guidance path that family is wanted.
Due to the interest hot spot to be come in handy when the walking of family on feature section, so if only by most short-range missile air route
The algorithm of diameter is unable to satisfy the individual demand of user.And this step can screen some alternative navigation route segments, can take into account
The individual demand of user.
Obtain the three-dimensional information for being greater than the building of preset threshold length on guidance path.By the way that preset threshold is arranged
The three-dimensional information of the building of length can reduce some temporary structures interspersed among operand, such as road both sides
Or some newsstand facilities etc., these three-dimensional informations for being less than the building of preset threshold length can be ignored.
