Method.
In practical applications, the present invention is based on the specific implementation of the phonetic navigation method of WEB, pass through following embodiment
Explanation.
Embodiment 1
In order to solve the problems, such as that existing WEB terminal Voice Navigation can not realize phonetic synthesis and play offline, in the present embodiment
A kind of speech guide system based on WEB is proposed, is mainly realized by following modules, is respectively：Navigation module, this part pass through
CANVAS, which draws, generates map, and external map API (application programming interface) is called to generate map, the present embodiment in WEB terminal
Middle calling is Baidu map API, other digital map navigation programs can also be selected according to actual conditions；Locating module is positioning
The WEB equipment with positioning function is monitored in the process to move, such as the process of B points is moved to from A points, position when can obtain mobile
Confidence ceases, and the locating module in the present embodiment is based on GPS technology, other can also be selected to position skill according to actual conditions
Art, such as Beidou satellite navigation positioning, GPS positioning module is during practical application, by the position location API for calling WEB
Continue audiomonitor trend, and it is indirect in positioning built in WEB, residing longitude and latitude is fed back when equipment is in mobile status to be sat
Mark；Phonetic synthesis sound module, when GPS positioning, which reaches route, has the point of navigation information, the corresponding navigation letter of phonetic synthesis
Breath, for example, when GPS positioning shows " walking 50 meters, turn left " in the point of some longitude and latitude, then phonetic synthesis broadcasting " walk 50 meters, to
The voice of left-hand rotation ".
Further include a correction module in addition to above-mentioned module, in this system, when GPS positioning and navigation programming route point are produced
When raw deviation, deviation is calculated, the actual distance that 1 longitude on map corresponds approximately to is 111 kms, and 1 latitude is about right
The actual distance answered is * 111 kms of cos (latitude), poor according to the longitude and latitude put in GPS positioning and navigation programming route, is calculated
In the deviation of longitude and latitude, then according to the conversion of longitude and latitude and actual distance, true deviation rice number is calculated, module of rectifying a deviation
Allowing GPS positioning and the programme path of navigation, there are certain errors, in 50 meters of error range, it is believed that be GPS positioning point
Belong to the same point with point nearest on navigation programming route, such as outbeach is all had arrived in about 50 meters around outbeach.
Realize that the real process of Voice Navigation is as follows by above system, in the present embodiment, navigation module first can be
Line generates a current location from equipment residing for WEB to the navigation programming route of specified terminal, is being manually entered navigation terminal
Afterwards, the navigation API of Baidu map is called to generate a bar navigation programme path (without installation) online, this route is actually one
The geographical longitude and latitude point composition of series can be arranged some navigation hint information in certain turnovers or important longitude and latitude point, generate
After programme path, locating module calls the GPS positioning API of WEB terminal, it can continue to supervise the situation of movement of equipment, when equipment is in
When mobile status, the API of GPS positioning can obtain the latitude and longitude information in geographical location residing for current device, then on map
Update the geographical latitude and longitude information that is presently in, and with the longitude and latitude that generates the point with navigation hint information on navigation programming route
Degree is compared, and system is constantly in presence in the process, when putting actual range on equipment GPS positioning and navigation routine
Error in 50 meters when, correction module thinks that current device positioning be in this point, if this point with navigation information,
Speech synthesis engine API is called, no matter system is in online or off-line state at this time, due to existing windows Mac systems
System carries speech synthesis engine in system layer, and compatibility is good at WEB and supports multilingual phonetic synthesis, in this way
Phonetic synthesis by network without can be thus achieved, therefore the speech synthesis engine called can be applied offline, therefore at this time may be used
It normally to carry out phonetic synthesis to navigation information, and is played out in equipment, navigation interface when practical application on WEB is as schemed
Shown in 2.
By the above method as can be seen that the effect of three aspects may be implemented in the system that the present embodiment proposes：First, base
It is realized in WEB technologies, phonetic synthesis can be realized under most modern browsers, and since modules are to pass through calling
The API of external program is realized, therefore this system is suitable for the web browser with positioning function, while simultaneous without installation
Hold mobile terminal Chrome browsers；Second is that the phonetic synthesis is based on system, it can be accessed without network, other opposite voices close
At mode, greatly reduce network request quantity, undoubtedly substantially increase application performance；Third, the phonetic synthesis mode be based on be
The support of system can support Chinese and English phonetic synthesis, and principle is simple, does not depend on environment.
Embodiment 2
Essentially identical based on the phonetic navigation method of WEB and the process in embodiment 1 in the present embodiment, difference lies in this realities
It applies system in example and is initially in off-line state, when generating navigation routine, since digital map navigation is answered outside currently the majority
Offline map is preserved with tool, therefore can also realize the generation of navigation routine, and locating module, correction module and voice are led
Boat synthesis module is not influenced can be used normally by online and offline situation, therefore in the present embodiment, can also be normal
Realize the web page navigation of WEB terminal.
Embodiment 3
Essentially identical based on the phonetic navigation method of WEB and the process in embodiment 1 in the present embodiment, difference lies in this
In embodiment when generating navigation routine, system is online, and system then enters off-line state later, due to being at this time
System has generated navigation routine, and prompts point comprising several navigation spots and navigation information in navigation routine, and locating module and
Module of rectifying a deviation can offline normal use, therefore system still can it is normal between computing device current location and navigation spots away from
From when equipment prompts point close to navigation information, the Voice Navigation synthesis module that can be used offline prompts point to navigation information
The voice messaging of upper holding is synthesized and is played offline, to normally realize the web page navigation of WEB terminal.
In this description, the present invention is described with reference to its specific embodiment.But it is clear that can still make
Various modifications and alterations are without departing from the spirit and scope of the invention.Therefore, the description and the appended drawings should be considered as illustrative
And not restrictive.
