Embodiment
Fig. 1 illustrates the pie graph of the destination image ratio of first embodiment of the invention compared with indexing unit 100.Destination image ratio realizes radio communication compared with indexing unit 100 by network and outside live-action map database 200.Live-action map database 200 can be as GoogleStreetView(Google streetscape) etc. external data base, wherein store the detail image data of streetscape, this live-action map database can be can the image data base of real-time update.
Destination image ratio mainly comprises following several functional unit compared with indexing unit 100: navigation portion 101, input operation part 102, control part 103, shoot part 104, obtaining section 105, storage part 106, comparing section 107, display part 108.Wherein, the destination information that navigation portion 101 inputs according to input operation part 102, display part 108 shows electronic chart and on electronic chart, marks current location and destination locations, and driving from current location to destination locations or Walking Route.Input operation part 102 realizes the input of user by screen touch-control or Speech input.Navigation portion 101 can adopt navigator in prior art, such as vehicle mounted guidance or Mobile Telephone Gps etc.
When user arrives after near destination according to the navigation in navigation portion 101, if still cannot determine which concrete destination is actually, then generate the instruction starting and compare retrieval by input operation part 102.Control part 103 is after receiving this startup and comparing the instruction of retrieval, start shoot part 104, make this shoot part with the current location in electronic chart towards the direction of destination locations for carrying out scanning shoot in certain limit near benchmark, obtain multiframe continuous print shooting image.The continuity degree of described multiframe continuous print shooting image can be arranged as required, such as 10 frames per second.So-called current location can be judged by observation electronic chart by user towards the direction of destination locations, also can be according to navigation portion detect the current location that the obtains direction towards destination locations.So-called with the current location in electronic chart towards destination locations direction for certain limit near benchmark can be as shown in Figure 3, refer in electronic chart, determine that current location is behind the direction of destination, the certain limit determined near its left and right sides, the reason of this certain limit selected is unlikely to too wide in range to make the selection of coverage have certain Objective, but also having certain amplitude is unlikely to too narrow and small.Even certainly this certain limit is also fine with 180 ° even scope of 360 ° that current location is benchmark towards the direction of destination locations, just the frame number of shooting image that obtains of such scanning shoot is more, correspondingly requires higher processing power.
Shoot part 104 can utilize vehicle-mounted shooting head also can utilize the shooting head of portable unit such as mobile phone.The multiframe shooting image taken by shoot part 104 is stored in storage part 106 for comparison afterwards.
Simultaneously, control part 103 is after receiving described startup and comparing the instruction of retrieval, according to the distance of the current location and destination locations of coming auto-navigation portion 101 and current location towards the direction of destination locations, obtaining section 105 is made to obtain reference picture from described live-action map database 200.In theory, according to the distance of current location and destination locations and current location towards destination locations these two parameters of direction acquired by reference picture be unique.But actual conditions are, due to difference (the such as Various Seasonal of the time period that reference picture itself obtains, time period different among one day), this reference picture itself has some differences, the image that such as summer, wooded blocked buildings is different from the image taken when winter, trees were withered, and such as, image captured by dusk and high noon also can be different.In addition, due to maintenance and the ruuning situation of live-action map database 200 itself, its image update situation is also different, such as, the mode real-time update such as can to share by the data cloud of online friend, thus may store the view data at a large amount of same visual angle.Therefore, reference picture can be one and also can be multiple.
Then, according to the control of control part 103, by comparing section 107 image is taken to the described multiframe continuous print from described storage part and reference picture compares, when the similarity of shooting image and reference picture is higher than the ratio preset, be then defined as both couplings.Method as concrete image comparison can adopt various manner of comparison of the prior art, and such as profile manner of comparison, binary conversion treatment manner of comparison, division block manner of comparison etc., be not described in detail in this.When comparing section 107 to find with the similarity of reference picture higher than the ratio preset (similarity of such as 90%), control part 103 makes display part 108 show this shooting image that the match is successful, and on this frame shooting image, mark destination according to the cartographic information in live-action map database, such as go out destination with thick circle, or show destination with different colours or high light display, identify as long as be convenient to user and find destination accordingly.As shown in Figure 4, in figure, 1300 represent the shooting image that the match is successful, and 1301 represent by the destination (or destination building) marked.If comparing section 107 does not find and the shooting image of the similarity of reference picture higher than the ratio preset, then also show similar " without matching image " such prompting by display part 108.In addition, also matching result (the match is successful or without coupling) is notified by auditory tone cues portion 109.Certainly, auditory tone cues portion 109 is selectively arranged, and also can omit.
Separately, when comparing section 107 does not find and the shooting image of the similarity of reference picture higher than the ratio preset, also make the scanning shoot expanded range of shoot part 104 by control part 103, and again take.Then compared once again by comparing section 107.
Fig. 2 is the process flow diagram of the destination image search method of display first embodiment of the invention.
In step S201, according to the destination information of user's input, display electronic chart also marks destination locations and current location thereon, is namely equivalent to the action that navigation portion carries out.In step S202, the operation according to user generates the instruction starting and compare retrieval.Then, in step S203, the instruction of retrieval is compared according to above-mentioned startup, by making a video recording, first-class shoot part carries out scanning shoot, the scope of scanning shoot can be with the current location in electronic chart towards the direction of destination locations for certain limit near benchmark, obtain multiframe continuous print shooting image thus, simultaneously obtain reference picture towards the direction of destination locations from live-action map database according to the distance of current location and destination locations and current location, and store above-mentioned shooting image and reference picture.
Then, enter into step S204, image ratio is carried out comparatively to shooting image and reference picture.
Then in step S205, judge whether shooting image and reference picture mate, usually a proportion threshold value can be preset, then judge that both mate when shooting image and the similarity of reference picture are greater than this proportion threshold value, enter into step S206, namely show the shooting image that this frame mates with reference picture, and thereon destination is marked.If step S205 judges shooting, image does not mate with reference picture, then, in step S207, unmatched result is informed to user.
