Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
In the following description, only by the mode of explanation, some example embodiment of the present invention has been described.Undoubtedly, those of ordinary skill in the art can recognize, without departing from the spirit and scope of the present invention in the situation that, can revise described embodiment by various mode.Therefore, accompanying drawing is illustrative with being described in essence, instead of for limiting the protection domain of claim.In this manual, identical Reference numeral represents same or analogous part.
Fig. 1 is process flow diagram, shows the improving method of the road-map described in one embodiment of the present of invention.As shown in Figure 1, first, in step S10, from predefined Internet user's moving position transacter, obtain the Internet user moving position data corresponding with Internet user's moving position in predetermined geographic.Specifically, before implementing the improving method of road-map of the present invention, first set up Internet user's moving position transacter, this device can be for example Website server, for from partner site or ad hoc website collect the moving position data of Internet user when movable out of doors.
In more detail, along with the development of consumer electronics, a lot of people can use the electronic equipment with global navigation satellite function (as GPS) to record some movable details in the time carrying out outdoor activities now, for example whilst on tour uses the camera with navigation feature to take pictures, while climbing the mountain, use GPS to record movement locus, while running on foot, use human body electronic equipment to record step number etc.(for example such as, in the application data (photo, step number etc.) that these electronic equipments are concerned about at recording user, often also record by way of parenthesis the position data of position while producing these application datas, longitude and the latitude etc. of position), these moving positions may be on known road, also may be on not quite clear road.A lot of people like these application datas to be uploaded to each internet site server by internet, to share with other people, these application datas are accompanied with the position data while generating these application datas.Thereby, can collect these position datas from each internet site server end, collect Internet user's moving position data.
Can adopt several different methods to improve the collection efficiency of Internet user's moving position data.For example, can cooperate with each internet site, to collect the moving position data that its a large amount of Internet user who has uploads from these partner sites; Also can set up ad hoc website with centralized collection Internet user moving position data.Reward mechanism further can be set, to encourage Internet user have a mind to or upload by mistake, more its moving position data, even, can set up professional to upload specially its moving position data and relevant time data etc.
Be further detailed below by example.Fig. 2 is schematic diagram, shows the topomap in certain mountain area.The topomap in certain mountain area shown in Fig. 2 comprises mountain range 10, river 20, known road 30, not quite clear road 41 and not quite clear road 42, wherein, mountain range 10 use level lines (dotted line) represent, river 20 use hacures represent, not quite clear road 41 is narrow winding trails, though not quite clear road 42 is the transitable waste roads of unshaped.Fig. 3 is schematic diagram, shows the existing road-map corresponding with certain alpine terrain figure in Fig. 2.As shown in Figure 3, show known road 30 in this existing road-map acceptance of the bid, but do not mark not quite clear road 41 and not quite clear road 42.Fig. 4 is schematic diagram, show the moving position (representing with solid stain) that a large amount of Internet users was once crossing when movable in certain mountain area shown in Fig. 2, wherein, at these moving position places, the application data that Internet user generated and uploaded to website subsidiary position data (for example longitude and latitude) (for example, photo etc.), these position datas are collected by described Internet user's moving position transacter.
Return to Fig. 1, in step S20, the described Internet user's moving position data based on obtaining in step S10 generate the road that can demarcate in road-map.The method that generates the road that can demarcate based on Internet user's moving position data in road-map is a lot.Fig. 5 and Fig. 6 are schematic diagram, show respectively two examples that generate the road that can demarcate according to Internet user's moving position data in road-map, wherein, in Fig. 5 and Fig. 6, solid stain is the moving position of the Internet user in predetermined geographic, and these moving positions for example, represent with moving position data (longitude and latitude).As shown in Figure 5 and Figure 6, first from described Internet user's moving position data, remove those correspondences and Internet user's moving position data of isolated positions point or bulk location point, for example, the corresponding Internet user's moving position of solid stain 50 data in Fig. 5 and Fig. 6.These isolated positions points or bulk location point may be corresponding rest place, also may be some the scattered location points on the road of unfashioned road or few people's process, can't determine uniquely road according to these scattered location points, therefore, in the process of current perfect road map, can put aside these location points.
Then, remaining Internet user's moving position data are carried out to sectional curve matching, and the each section of curve simulating connected, to generate the road that can demarcate in road-map.
Particularly, described predetermined geographic can be divided into many zonules, Internet user's moving position data in each zonule are carried out to sectional curve matching, and the each section of curve simulating connected, the road that final generation can be demarcated on road-map.The dividing mode that should be noted that described presumptive area is not unique, as shown in Figure 5 and Figure 6, can have multiple dividing mode, and the road obtaining under every kind of dividing mode can compare and comprehensively, to obtain the road that does not rely on concrete division.
Return to Fig. 1, then, in step S30, the road in the road-map of the described road generating and existing described predetermined geographic is compared, thereby the road of not yet demarcating in this road-map in the described road generating is newly demarcated in this road-map.Fig. 7 is schematic diagram, shows the road-map after improving of the present invention, wherein, on the road-map after improving, not only has known road 30, has also newly calibrated not quite clear road 41 and not quite clear road 42.
Along with increasing gradually of Internet user's moving position data of collecting, can regularly or irregularly carry out above-mentioned steps S10-S30, thereby constantly upgrade road-map, make original not accurate enough road become more accurate.
Further, for the road newly calibrating, can calculate the length of these roads on road-map, and this link length information is combined in road-map, for user's reference of road-map.
In addition, can also calculate the confidence level of the road of new demarcation in road-map, and by the road mark in predetermined threshold with a low credibility in these roads out.Specifically, in the time that Internet user's moving position data of collecting from a certain region are fewer, the confidence level of the road being generated by these data may be lower; Or although the data of collecting are many, these data are relatively disperseed, unanimously spend poor, thereby the road being generated by these data may be not unique, in these cases, can calculate the confidence level of the road of new demarcation in road-map.The definition of confidence level can have multiple, and those skilled in the art can define according to concrete curve fitting algorithm, for example can be with the inverse of curve error as confidence level.When certain the new road of demarcating with a low credibility is during in predetermined threshold, this road can be marked on road-map, for example, in Fig. 7, not quite clear road 42 use dotted lines indicate, and show that the confidence level of this road is not too high, only for reference.Along with the data of collecting increase, while upgrading road-map, original not high road of confidence level may become the road that confidence level is higher at every turn.
It should be noted that, Internet user's moving position data of collecting are less not necessarily means that the confidence level of the road being generated by these data is necessarily lower, for example, if the moving position data that indivedual Internet users provide are very complete (, the moving position data that the Internet user who does so intentionally or professional provide), the confidence level of the road being generated by these few complete data still can be very high.Even, provide the time of moving position data according to these indivedual Internet users, can also determine more road information, time that the one section of road of for example passing by is required etc.
The improving method of road-map of the present invention has as above been described with reference to figure 1-Fig. 7.Said method of the present invention can adopt software to realize, and also can adopt hardware to realize, or adopts the mode of software and hardware combination to realize.
