Embodiment
Hereinafter will and combine embodiment to specify the present invention with reference to accompanying drawing.Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.
A kind of location processing method is provided in the present embodiment, and Fig. 1 is the process flow diagram according to the location processing method of the embodiment of the invention, and is as shown in Figure 1, and this flow process comprises the steps:
Step S102, images acquired information;
Step S104; Obtain and this image information corresponding map coordinate; And the azimuth information of the subscriber equipment when images acquired information; For example, this azimuth information can for following one of at least: the elevation angle that reports towards the angle on axis and the ground during with angle direct north, subscriber equipment images acquired information that obtained, according to acceleration transducer according to earth magnetism;
Step S106 confirms subscriber equipment present located position according to map reference that gets access to and azimuth information.
Through above-mentioned steps, according to the image information corresponding map coordinate that collects, and the azimuth information of subscriber equipment gets access to this subscriber equipment present located position during images acquired information; Method according to images acquired can cover bigger face; For example, in the indoor collection that also can realize image, with the image corresponding map coordinate that collects; Consider the azimuth information of subscriber equipment; Thereby obtain the current position the most accurately of subscriber equipment, how solved provides auxiliary map positioning service to make positioning service more accurate in mobile device in the correlation technique, the quick and wider problem of coverage rate; And then reached and make positioning service more accurate, fast and the wider effect of coverage rate.
Obtain with image information corresponding map coordinate and can adopt multiple mode, for example, can in database, store and image information corresponding map coordinate in advance; When collecting image information, just can search the corresponding map coordinate with the corresponding relation of corresponding map reference, certainly according to institute's image stored; When adopting in such a way; Storage is big especially with the amount of the image corresponding map coordinate that collects, therefore, when searching each side expend also bigger.Herein, a kind of preferred processing mode is provided, when collecting image information, contour curve that can the pairing image of first recognition image information; The profile that is about to the corresponding image of image information is retouched out, afterwards, from database, searches the similar curves similar with contour curve; Obtain and this similar curves corresponding map coordinate, therefore, confirm that the pairing map reference of this similar curves is and image information corresponding map coordinate.
When confirming subscriber equipment present located position according to the map reference that gets access to and azimuth information; Also can take multiple processing mode; According to current to images acquired and obtain the corresponding map coordinate and whether record that azimuth information is done is merely once current; If when also having other record; Promptly have the record that is carried out when gathering other scene before or afterwards, can adopt two kinds of processing modes, first this moment: directly confirm subscriber equipment present located position according to gathering current scene institute information recorded; The second, according to gathering current scene institute's information recorded and being directed against the position that other scene institute information recorded is confirmed subscriber equipment.And if being merely when being directed against current scene institute information recorded of can obtaining then can only describe in the face of above-mentioned two kinds of processing modes down according to above-mentioned described first kind of processing mode.
Directly confirm subscriber equipment present located position (abbreviate the single-point map location here as and confirm method): obtain first distance between image information and subscriber equipment earlier according to gathering current scene institute information recorded; According to map reference that gets access to and azimuth information, and first distance is confirmed subscriber equipment present located position.For example; When obtaining the current position coordinates of subscriber equipment; The direction of at first confirming the current place of subscriber equipment according to map reference that gets access to and azimuth information is then confirmed the current position coordinates of subscriber equipment according to above-mentioned first distance of being obtained before again, certainly when concrete the processing; Can consider that also other comparatively possibly influence the other factors of result, thereby make result more accurate.
Again for example, after obtaining the distance of first between image information and subscriber equipment, the height above sea level of all right pairing image of images acquired information; Confirm the height above sea level of the current present position of user according to this height above sea level that collects, first distance and azimuth information.The process of confirming can be according to the corresponding height above sea level of image information that collects; And the geometric relationship between the residing actual height above sea level of subscriber equipment is calculated acquisition; Such as; Confirm in the height above sea level of pairing height above sea level of the image information that collects and the current present position of subscriber equipment the line of peak among both and the angle between the ground through azimuth information, and difference and the tangent relationship between above-mentioned first distance that obtains through the two height above sea level height above sea level that obtains the current present position of subscriber equipment.
According to gathering current scene institute's information recorded and confirming that to other scene institute information recorded the position of subscriber equipment (not only is under one the situation at the record of the map reference that gets access to; Can preferentially select this processing mode; Abbreviate the multiple spot map location here as and confirm method): at first; Whether judgement is merely one to the record of the map reference that gets access to, so that follow-uply can confirm the position according to multiple spot; In judged result is under the situation not; Obtain the second distance between the pairing map reference of another image information and the image information corresponding map coordinate in another record; Need to prove that the second distance here is the relative distance of the map reference of the pairing image of image information gathered in noting down to two scenes); Confirm subscriber equipment present located position according to second distance and azimuth information; For example; Obtain the straight line at place, the current present position of subscriber equipment according to institute's information recorded in two scenes, confirm subscriber equipment present located exact position according to azimuth information (for example, earth magnetism is towards that obtained and angle direct north) and above-mentioned second distance (relative distance) afterwards; Through such processing mode; Since accessed recorded information before adopting, thereby increased the speed of handling, improved treatment effeciency.
