With the increasing development and popularization of computer technology, geographic Information Systems (GIS) play an increasingly important role in the production and life of people. For example, for a telecom operator, information such as wireless network distribution, coverage of a wireless network, and geographical distribution of a poor cell of the network needs to be known through geographical information data in a GIS platform.
Geographic information data of a GIS platform is generally derived from raw data provided by professional mapping units, and the geographic information data comprises house numbers, for example. The house number query based on the GIS platform is very important for network optimization, complaint treatment and other works of operators. However, the mapping units cannot collect the number of house numbers in full due to the huge number of house numbers, and the operators cannot purchase the house numbers in full due to the purchase cost. Therefore, some problems are brought, and the house numbers of some places in the GIS platform cannot be inquired and determined because the house numbers adopted or purchased are not full, namely only inquiry and positioning of information of a limited number of purchased house numbers can be realized.
If all the house number information is purchased completely, the query positioning based on the total house number information is realized, and the cost expenditure is high. Meanwhile, the display of all house number information by using the GIS is not beneficial to the configuration of map layers, and the visual display effect of the GIS is also affected.
In order to solve the problems in the prior art, the embodiment of the application provides a method, a device, equipment and a computer storage medium for determining a house number.
The technical conception of the embodiment of the application is as follows: firstly, acquiring coordinates of a target object and a first place, wherein the first place comprises a place which is positioned on the same street as the target object and has a known house number; then, according to the coordinates of the target object and the first place, determining a first distance between the target object and the first place; determining a house number of the target object according to the first distance and a preset interpolation function; since the interpolation function is obtained from the house numbers of the N second places, the house numbers of the first places, and the second distances between the first places and each of the second places, which are on the same street as the target object and whose house numbers are known, the house numbers of the target object can be determined from the distance between the target object and the first places and the correspondence between the distances between the known places and the first places in the interpolation function and the house numbers.
The method for determining the house number provided by the embodiment of the application is first described below.
Fig. 1 is a flow chart of a method for determining a house number according to an embodiment of the present application. As shown in fig. 1, the method may include the steps of:
s101, acquiring coordinates of a target object and a first place.
In an embodiment of the present application, the target object may be any location or building or other object, and the first location may be, for example, a location that is on the same street as the target object and has a known number. To facilitate subsequent calculations, the first location may include, for example, a location where a maximum house number or a minimum house number is located among all locations where a house number is known for a street where the target object is located, as an example.
For example, there are 4 locations of known house numbers in the street where the target object is located, location a, location B, location C, and location D, respectively. The house number of the place A is 13, the house number of the place B is 19, the house number of the place C is 27, and the house number of the place D is 33, so that among all places of the known house number of the street where the target object is located, the place where the largest house number is located is the place D corresponding to the house number 33, and the place where the smallest house number is located is the place A corresponding to the house number 13. Then, the first location may be location a or location D.
Here, the first location is not limited to the location where the largest house number or the smallest house number is located among all locations of the known house numbers, but may be other locations of the known house numbers, and the present application is not limited thereto.
Specifically, in S101, the coordinates of the target object may be fetched in a geographic information system application (hereinafter abbreviated as GIS application), and the coordinates of the first location may be fetched accordingly. The coordinates here may be latitude and longitude coordinates, for example.
In order to achieve that after the target object is selected or input, the coordinates of the first location of the street where the target object is located are automatically retrieved, as an example, before S101 is performed, for example, known house numbers may be grouped according to street names, then in S101, the street where the target object is located may be determined according to the street names of the target object, then the coordinates of the first location of the same street as the target object may be determined, and the coordinates of the first location may be retrieved.
In the process of grouping the house numbers, considering the naming requirement of the house numbers of each place, for example, the requirement of following the single and double number separation naming of two sides of a road is required, in order to combine with the actual situation and ensure the accuracy of subsequent calculation, as an example, the embodiment of the application can group the known house numbers according to the street names and the single and double numbers, and the street names of all the house numbers in each group after grouping are the same and are the single number or the double number. I.e. each street may be divided into two groups of house numbers, one group being single and the other group being double, for example.
In practical applications, the first location may be, for example, a location that is on the same street and on the same side of the road as the target object and has a known house number. In S101, for example, it may be determined on which side of the road the house number of the target object is a single number or a double number, and when it is determined that the house number of the target object is a single number, the coordinates of the first location of the single number group of the street on which the target object is located are retrieved; and when the house number of the target object is determined to be the double number, the coordinates of the first place of the double number group of the street where the target object is located are called.
After the coordinates of the target object and the first place are acquired, S102 is performed.
S102, determining a first distance between the target object and the first place according to the coordinates of the target object and the first place.
S102 will be described below with reference to fig. 2. Fig. 2 schematically illustrates a target object, a first location and a second location according to an embodiment of the application. As shown in fig. 2, the point d is a location where the target object is located, for example, the point a is a first location, and the points b and c are both second locations. As can be seen from fig. 2, the street on which the target object is located is not a straight line, so if the distance between the target object and the first location is calculated directly according to the coordinates of the target object and the coordinates of the first location, the calculated distance is the straight line distance between the two points, and the deviation is larger when the house number is determined according to the straight line distance.
Specifically, S102 may include the steps of:
A first step of determining M second sites between the target object and the first sites according to the coordinates of the target object and the first sites.
In the embodiment of the application, the second place is a place which is located on the same street as the target object except the first place and has a known number. More specifically, the second location is, for example, a location which is located on the same street as the target object and on the same side of the road as the first location and has a known house number, that is, when the house number of the target object is a single number, the second location is a second location of a single number group of the street on which the target object is located; when the house number of the target object is double, the second place is the second place of the double number group of the street where the target object is located.
The coordinates of the second location are known, for example, latitude and longitude coordinates. In the first step, for example, M second places whose longitude coordinates are between the longitude coordinates of the target object and the longitude coordinates of the first place may be determined from the longitude coordinates of the target object and the longitude coordinates of the first place in a single number group or a double number group of the street where the target object is located. Of course, M second locations with the latitude coordinate between the latitude coordinate of the target object and the latitude coordinate of the first location may be determined from the single-number group or the double-number group of the street where the target object is located according to the latitude coordinate of the target object and the latitude coordinate of the first location.
And a second step of accumulating and calculating the distances among the first place, the M second places and the adjacent places in the target object to obtain a first distance.
In the embodiment of the present application, the calculation expression of the distance between any two adjacent sites is as follows:
C＝sin(LatA)*sin(LatB)*cos(LonA-LonB)+cos(LatA)*cos(LatB) (1)
D(A,B)＝R*arccos(C)*π/180 (2)
Wherein LonA and LatA are longitude coordinates and latitude coordinates of the location a respectively, lonB and LatB are longitude coordinates and latitude coordinates of the location a respectively, C is an intermediate parameter, R is an earth radius, an approximate value is 6371 km, and the unit can be converted according to actual conditions; pi is the circumference ratio, sin is a sine function, cos is a cosine function, arccos is an inverse cosine function, and D (A,B) is the distance between location A and location B.
As shown in fig. 2, the distance D (a,b) between the place a and the place b, the distance D (b,c) between the place b and the place c, and the distance D (c,d) between the place c and the place D are sequentially calculated according to the above expressions (1) and (2).
Then, a first distance between the location d and the location a is calculated, expressed as:
D(a,d)＝D(a,b)+D(b,c)+D(c,d) (3)
Wherein D (a,d) is the first distance between location D and location a.
It should be noted that, for the first place, considering that the diversity of the samples is in direct proportion to the accuracy of the result, if there are more samples of the known house number between the point d and the maximum house number, the first place is the place corresponding to the maximum house number, and the street-following distance between the point d and the maximum house number is calculated; otherwise, if more known house number samples exist between the point d and the minimum house number, the first location is the location corresponding to the minimum house number, and the street-following distance between the point d and the minimum house number is calculated.
After determining the first distance between the target object and the first location, S103 is performed.
S103, determining the house number of the target object according to the first distance and a preset interpolation function.
In the embodiment of the application, the interpolation function is based on an interpolation method and is obtained according to the house numbers of N second places which are on the same street with the target object and have known house numbers, the house numbers of the first places and the second distance between the first place and each second place.
For ease of understanding, the interpolation function in S103 will be described below with reference to fig. 2 as an example.
As shown in fig. 2, assuming that the first location is location a, the target object is location d. The interpolation function is obtained by the following steps:
The first step is to calculate the second distance between the location of each known house number and the first location. The second distance between the place a and itself is x 0 =0, the second distance between the place b and the place a is x 1＝D(a,b), the second distance between the place c and the place a is x 2＝D(a,c), the second distance between the place f and the place a is x 3＝D(a,f), and so on until the second distances between the places and the first places of all known house numbers are calculated. I.e. a second distance between each third location and the first location is calculated, the third location comprising the first location and N second locations.
And a second step of determining the corresponding relation between the house number and the second distance.
f(x0)＝13,f(x1)＝19,f(x2)＝27，……
And by analogy, obtaining the corresponding relation between each second distance and the license plate number.
Thirdly, establishing an interpolation function N (x) based on the corresponding relation between the second distance and the license plate number, wherein the expression is as follows:
Where f 0＝f(x0), the 0-order difference quotient about f (x) is defined as its function value, i.e., f [ x i]＝f(xi), and generalized to k-order, f [ x 0,x1,x2,…,xk-1,xk ] is the k-order difference quotient of f (x), expressed as:
Wherein ω k (x) is a k-degree polynomial,
Wherein x represents a first distance between the target object and the first place, x j represents a second distance between a j-th second place and the first place in all second places between the target object and the first place, k represents a total number of the second distances, x i represents an i-th second distance, and i, j and k are natural numbers.
Thus, the first distance x between the target object and the first place is used as an input value and is input into the interpolation function N (x), and the output value of the interpolation function N (x), namely the house number of the target object, can be obtained.
The above S103 is an example of the embodiment of the present application, but the interpolation method of the embodiment of the present application is not limited to the newton interpolation method, and may be another type of interpolation method, for example, the lagrangian interpolation method, and the present application is not limited thereto.
In order to ensure the accuracy of the house number of the determined target object, as an example, before S101 is performed, the embodiment of the present application may further include the steps of:
After the known house numbers are grouped by street name and single or double number, the wrong house numbers in each group are screened and deleted, and the status of the wrong house numbers is marked as deleted status.
Specifically, all house numbers in each group are first sorted in order from large to small or from small to large.
Then, it is determined whether the (i+1) th and (i+2) th house numbers are correct or not, and i is a positive integer, based on the (i+1) th, i+2 th and (i+3) th house numbers in each group. It will be appreciated that based on the adjacent four house numbers in each group, it is determined whether the middle two house numbers of the four house numbers are both correct.
Specifically, the places where the ith, the (i+1) th, the (i+2) th and the (i+3) th house numbers are located are determined; judging whether a first included angle between the places where the ith, the (i+1) th and the (i+2) th house numbers are located is within a preset range, judging whether a second included angle between the places where the (i+1) th, the (i+2) th and the (i+3) th house numbers are located is within the preset range, and determining that at least one of the (i+1) th and the (i+2) th house numbers is incorrect when at least one of the first included angle and the second included angle is not within the preset range.
As shown in fig. 3, the places corresponding to the adjacent four house numbers, namely, place a, place b, place c, and place d. Judging whether a first included angle abc among the place a, the place b and the place c is in a preset range or not, and judging whether a second included angle bcd among the place b, the place c and the place d is in the preset range or not.
When the first included angle abc and the second included angle bcd are both in a preset range, the house numbers of the place b and the place c are correct; when at least one of the first included angle abc and the second included angle bcd is not in the preset range, for example, the first included angle abc is smaller than the minimum value of the preset range, and the second included angle bcd is larger than the maximum value of the preset range, at least one of the house numbers of the place b and the place c is indicated to be incorrect.
In the embodiment of the present application, the preset range may be, for example, 90 degrees to 270 degrees, and of course, other angle ranges are also possible, which is not limited to this. It should be noted that the first included angle and the second included angle may be calculated according to a clockwise direction or calculated according to a counterclockwise direction, and the present application is not limited thereto.
In the case where it is determined that at least one of the (i+1) th and (i+2) th house numbers is incorrect, it is determined that the wrong house number is the (i+1) th house number and/or the (i+2) th house number, based on the (i, i+1) th, (i+3) th and (i+4) th house numbers in each group and the (i, i+2) th, i+3 th and (i+4) th house numbers in each group.
Table 1 shows several judgment cases in the case where at least one of the (i+1) th and (i+2) th house numbers is incorrect.
TABLE 1
As shown in tables 1 and 3, when at least one of the (i+1) th house number (e.g., the house number of the place b) and the (i+2) th house number (e.g., the house number of the place c) is incorrect, the house number is extended backward by one house number, and the wrong house number is determined to be the house number of the place b and/or the house number of the place c based on the house numbers of the places a, b, d and f and the house numbers of the places a, c, d and f.
Specifically, when the ith, the (i+1) th, the (i+3) th, and the (i+4) th house numbers in each group satisfy the first preset condition, and the ith, the (i+2) th, the (i+3) th, and the (i+4) th house numbers in each group do not satisfy the second preset condition, it is determined that the wrong house number is the (i+2) th house number. In the case of (2) shown in table 1, for example, when the house numbers of the place a, the place b, the place d, and the place f satisfy the first preset condition, and the house numbers of the place a, the place c, the place d, and the place f do not satisfy the second preset condition, it is determined that the wrong house number is the house number of the place c.
Correspondingly, when the ith, the (i+1) th, the (i+3) th and the (i+4) th house numbers in each group do not satisfy the first preset condition, and the ith, the (i+2) th, the (i+3) th and the (i+4) th house numbers in each group satisfy the second preset condition, it is determined that the wrong house number is the (i+1) th house number. In the case of (3) shown in table 1, for example, when the house numbers of the place a, the place b, the place d, and the place f do not satisfy the first preset condition, and the house numbers of the place a, the place c, the place d, and the place f satisfy the second preset condition, it is determined that the wrong house number is the house number of the place b.
When the ith, the (i+1), the (i+3), and the (i+4) th house numbers in each group do not satisfy the first preset condition, and the ith, the (i+2), the (i+3), and the (i+4) th house numbers in each group do not satisfy the second preset condition, determining that the wrong house numbers are the (i+1) th house number and the (i+2) th house number. In the case of (4) shown in table 1, for example, when the house numbers of the place a, the place b, the place d, and the place f do not satisfy the first preset condition, and the house numbers of the place a, the place c, the place d, and the place f do not satisfy the second preset condition, it is determined that the wrong house numbers are the house number of the place b and the house number of the place c.
In an embodiment of the present application, the first preset condition includes: the third included angle between the (i+1) th place and the (i+3) th place where the (i+1) th house number is located is within a preset range, and the fourth included angle between the (i+1) th place and the (i+3) th place where the (i+4) th house number is located is within a preset range.

In the embodiment of the present application, the preset range may be, for example, 90 degrees to 270 degrees, and of course, other angle ranges are also possible, which is not limited to this. The specific determination process is described above, and will not be described herein.
In the case (1) shown in table 1, since one of the points b and c is erroneous data, the two points c and d cannot be correctly aligned with the two points b and d, and therefore the first case may be omitted.
As a simple and quick judgment mode, under the condition that at least one of the (i+1) th and (i+2) th house numbers is incorrect, whether the included angles between the (i+3) th and (i+4) th house numbers correspond to the places is within a preset range or not can be judged first, and when the included angles between the (i+3) th and (i+4) th house numbers correspond to the places are within the preset range, the (i+1) th house number and the (i+2) th house number are incorrect; when the included angles among the places corresponding to the ith, the (i+3) th and the (i+4) th house numbers are not in the preset range, the fact that the (i+3) th house number is possibly the wrong house number is indicated, and the judgment of the next cycle is needed.
Finally, under the condition that the (i+1) th house number and/or the (i+2) th house number is determined to be the wrong house number, deleting the wrong house number and marking the state of the wrong house number as a deleting state.
