The embodiment of the invention provides a map display method for restaurant stores, which comprises the steps of firstly obtaining the size information of a screen of a positioning information box of a display device; then, the actual distance from the display device to the stores is determined according to the positioning information, then the screen is divided into a plurality of rectangular areas, the stores are in one-to-one correspondence to the rectangular areas according to the screen size information and the actual distance, then store data in each rectangular area are screened to obtain displayable stores, and finally, a preset number of displayable stores are extracted to be displayed. As the stores in each rectangular area are screened, the number of the stores in each rectangular area is proper when the stores are displayed at last, the display data is small, and the display effect is greatly improved.
As a supplementary explanation to the above-described embodiment, acquiring the positioning information and the screen size information of the display device includes: acquiring screen longitude and latitude information of display equipment; specifically, four corners of a screen of the display device and longitude and latitude information of the center of the screen are acquired. And calculating to obtain the positioning information and the screen size information of the display equipment according to the longitude and latitude information of the screen. Specifically, longitude and latitude information of the center of a screen of the display device is used as positioning information of the display device; and calculating to obtain the size information of the screen according to the longitude and latitude information of the four corners of the screen of the display equipment. It can be understood that, since the screen of a general display device is rectangular, the screen size can be obtained by providing longitude and latitude information of four corners of the screen in the embodiment of the present invention, and the longitude and latitude information of the center of the screen can be obtained by calculating the longitude and latitude information of the four corners, or can be obtained by measuring by using a measuring device, which is not limited specifically herein. The longitude and latitude information of the screen is more accurate in positioning, the longitude and latitude information of the four corners can be obtained simultaneously and can be compared with each other, and due to the fact that the screen is generally rectangular, if the longitude and latitude information of the four corners cannot form a rectangle, the fact that the obtaining is wrong is shown. Meanwhile, the specific position information of the screen store can be displayed more conveniently according to the longitude and latitude information.
As an optional implementation manner of the embodiment of the present invention, corresponding all stores to a rectangular area according to the screen size information and the actual distance includes: generating a complete store map according to the actual distance and a preset scale; acquiring a partial store map matched with the size of a screen by taking the equipment positioning information as a center; and acquiring stores in each rectangular area on the acquired partial store map. It can be understood that the actual store is displayed on the screen after being reduced in equal proportion, the center of the screen is overlapped with the point of the center of the screen on the map when matching is carried out, and other maps with the screen size are displayed according to the proportion. The rectangular area, which is a store in the rectangular area divided at this time, corresponds to the store.
Since there are many local stores and there are few local stores, it is necessary to deal with stores in each rectangular area. Specifically, store data conditions in all adjacent rectangular areas of any rectangular area are obtained; obtaining the number of adjacent rectangular areas with store data according to the data condition; and deleting the store data in the rectangular area when the number exceeds a preset number value. Illustratively, one rectangular area has four adjacent rectangular areas, and if there are stores in all of the four rectangular areas, the store data in the middle rectangular area will be filtered and not displayed. Deleting store data within the rectangular area includes: deleting all store data in the rectangular area; or deleting the data of the stores in the rectangular area to make the number of the stores in the rectangular area be a preset value, namely only leaving the stores with the preset value.
However, in practical cases, even if there is no store number in the adjacent rectangular area, the store number in the rectangular area may be too large, and thus the store number in each rectangular area is acquired; and when the number of stores exceeds a preset value, randomly deleting the store data exceeding the preset value.
After the above series of steps, the number of displayable stores is obtained to be slightly more than the number of stores to be displayed, and illustratively, the number of stores to be displayed per area is 10, and the number of displayable stores is obtained to be 15, so that the number can be selected in extraction. After extraction, firstly, the distance between any two stores extracted from each rectangular area is obtained; and when the distance is smaller than the preset distance, re-extracting the preset number of stores. This step is to influence the display result because two stores are too close. Of course, each module is extracted independently of the other.
