Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is the process flow diagram of scenic spot guide to visitors figure localization method embodiment 1 of the present invention.As shown in Figure 1, this method can comprise:
Step 101: the latitude and longitude coordinates and the pixel coordinate that obtain two points on the described scenic spot guide to visitors figure;
(Global Positioning System GPS) obtains the latitude and longitude coordinates of two points on the guide to visitors figure of scenic spot can to pass through GPS.The pixel coordinate of two points as described in can obtaining by special image handling implement (as photoshop).
In the practical application, can obtain latitude and longitude coordinates and the pixel coordinate of distance two points farthest on the described scenic spot guide to visitors figure, in order to improve the bearing accuracy of the method for present embodiment.
Step 102: the actual latitude and longitude coordinates of obtaining the portable terminal position;
Can obtain the actual latitude and longitude coordinates of portable terminal position by the GPS module that arranges on the portable terminal.
Step 103: according to latitude and longitude coordinates and the pixel coordinate of described two points, calculate the actual pixels coordinate of described actual latitude and longitude coordinates correspondence;
According to the latitude and longitude coordinates of described two points, can calculate two between the some longitude distance and the distance between the latitude.According to the pixel coordinate of described two points, can calculate the distance of the horizontal direction of two points on the plane of scenic spot guide to visitors figure and the distance of vertical direction.According to the distance of the distance between two some longitudes with the horizontal direction of two points on the plane of scenic spot guide to visitors figure, can obtain the ratio of the horizontal range on longitude distance and the scenic spot guide to visitors figure.According to the distance of the distance between two some latitudes with the vertical direction of two points on the plane of scenic spot guide to visitors figure, can obtain the ratio of the vertical distance on latitude distance and the scenic spot guide to visitors figure.Again according to the actual latitude and longitude coordinates of portable terminal position, can calculate the distance of any one reference point on longitude and latitude in actual latitude and longitude coordinates and above-mentioned two reference point, again according to above-mentioned two proportionate relationships, just can calculate, the pixel of portable terminal position on the guide to visitors figure of scenic spot, with any one reference point in above-mentioned two reference point, in the horizontal direction with the distance of vertical direction, obtain the actual pixels coordinate of actual latitude and longitude coordinates correspondence, and then the pixel of this portable terminal position can accurately be shown.
Step 104: the point corresponding with described actual pixels coordinate on described scenic spot guide to visitors figure, point out the position of described portable terminal.
Point out the mode of the position of described portable terminal can have multiple.Can on the guide to visitors figure of scenic spot, will put with different and show with other regional colors, also this point can be shown with the form of glimmering.
From the above, in the present embodiment, by obtaining latitude and longitude coordinates and the pixel coordinate of two points on the guide to visitors figure of scenic spot, latitude and longitude coordinates and pixel coordinate according to described two points, calculate the actual pixels coordinate of the actual latitude and longitude coordinates correspondence of portable terminal position, and then can be on described scenic spot guide to visitors figure corresponding with described actual pixels coordinate point, point out the position of described portable terminal, can carry out the precision location and show the position of portable terminal in the scenic spot.
