For the understanding of the present embodiment, the following detailed description will be given of the embodiment of the present invention.
The first embodiment is as follows:

And extracting identification elements of point types from each identification region/identification topic, and constructing an identification content library of the point type problem map.
The point type map element standard library is used for determining point type map elements which need to be included in the standard library and a correct representation method according to laws and regulations, various normative documents, national standards and the like. In addition, a map recognition reference map is also constructed, which includes common point, line and plane type map elements for automatically recognizing and determining the position of the map.

and step S106, judging the point type map elements according to the judgment rule based on the point type map element model to obtain a judgment result.
Further, the point type map element standard library comprises identification regions, identification elements, comparison types of the elements, the number of the elements and the spatial positions of the elements.
Here, the identification region and the relevant identification element that are required to identify the point type map element are selected from the identification content library of the point type problem map.
Furthermore, the comparison type of the elements comprises similar elements and heterogeneous elements; the similar component is a component of the same category as the identification component, and the heterogeneous component is a component of a different category from the identification component.
Further, the number of elements includes an element constituting a minimum bounding rectangle, X Ratio of 、Y Ratio of Threshold, limit condition, bool Limitation of conditions Maximum value N of the number of elements max And a minimum value N min 。
Specifically, the number of elements may be 0, indicating that the element cannot be represented within the minimum bounding rectangle, and the maximum value N of the number of elements max And minimum value N min May be the same. The elements constituting the minimum outsourced rectangle refer to reference elements for constructing the minimum outsourced rectangle elements when determining the number of the elements; x Ratio of And Y Ratio of Means the position of the element in the minimum outsourcing rectangular element when determining the number of the elements; the threshold value is that the element is at a minimumA location-allowed threshold in the outsourced rectangular element; constraint and Bool Limitation of conditions This is a precondition for judging the number of elements.
Further, the spatial position of the element includes a reference map element, a relative positional relationship between the identification element and the reference map element in the X-axis direction, a relative positional relationship between the identification element and the reference map element in the Y-axis direction, an element constituting a minimum bounding rectangle, and X Ratio of 、Y Ratio of And a threshold value.
Here, the spatial position of the element refers to a relative positional relationship of the element with the map element of reference and a spatial position where the element is located among the elements constituting the minimum outsourcing rectangle.
Further, the reference map element is a map element whose relative positional relationship with the identification element is determined; the relative position relationship between the identification element and the reference map element in the X-axis direction comprises a relative position relationship obtained by subtracting the coordinates of the identification element and the reference map element in the X-axis direction, and a relative position relationship obtained by subtracting the coordinates of the reference map element and the identification element in the X-axis direction; the relative positional relationship between the identification element and the reference map element in the Y-axis direction includes a relative positional relationship obtained by subtracting the coordinates of the identification element and the reference map element in the Y-axis direction, and a relative positional relationship obtained by subtracting the coordinates of the reference map element and the identification element in the Y-axis direction.
Specifically, bool X1 The relative position relationship between the identification element and the coordinate of the reference map element in the X-axis direction after subtraction, and if the Bool value is True, the identification element is shown to be on the right side of the reference map element; if Bool is False, it means that the identification element is on the left side of the referenced map element or both coincide in the direction of the X-axis.
Bool X2 The relative position relationship is obtained by subtracting the coordinates of the reference map element and the identification element in the X-axis direction, and if the Bool value is True, the identification element is shown to be on the left side of the reference map element; if Bool is False, it indicates that the identified element is to the right of the referenced map element or that the two coincide in the direction of the X-axis. If Bool X1 And Bool X2 Both are False, indicating that they coincide in the direction of the X-axis.
Bool Y1 The relative position relationship is obtained by subtracting the coordinates of the identification element and the reference map element in the Y-axis direction, and if the Bool value is True, the identification element is on the upper side of the reference map element; if Bool is False, it means that the identification element is under the referenced map element or the two coincide in the direction of the Y-axis.
Bool Y2 The relative position relationship is obtained by subtracting the coordinates of the reference map element and the identification element in the Y-axis direction, and if the Bool value is True, the identification element is shown to be positioned under the reference map element; if Bool is False, it means that the identification element is on the upper side of the referenced map element or the two coincide in the direction of the Y-axis. If Bool Y1 And Bool Y2 Both False indicates that they are coincident in the direction of the Y-axis.
In addition, the element constituting the minimum bounding rectangle is a map element to be referred to when calculating the spatial position of the element, and the minimum bounding rectangle of the element is a basis for calculating the spatial position of the element.
Further, X Ratio of Taking the minimum outsourcing rectangle as a reference as an element, taking the lower left corner of the minimum outsourcing rectangle as an origin, and taking the ratio of the offset in the X-axis direction to the X-axis offset of the upper right corner of the minimum outsourcing rectangle; y is Ratio of Taking the minimum outsourcing rectangle as a reference as an element, taking the lower left corner of the minimum outsourcing rectangle as an origin, and taking the offset in the Y-axis direction as a ratio of the offset to the Y-axis offset of the upper right corner of the minimum outsourcing rectangle; the threshold value is an allowable error range when the offset of the element in the X axis and the Y axis is measured by taking the minimum outsourcing rectangle as a reference.
Further, step S106 includes the steps of:
step S201, when Bool Limitation of conditions When the point type map elements are true, acquiring the number of the point type map elements in a preset map area, wherein the preset map area comprises minimum outsourcing rectangular elements and X Ratio of 、Y Ratio of And a threshold value;
in particular, when Bool Limitation of conditions When = True, in advanceThe number of point type map elements that can be correctly identified by a computer within a map area is denoted by N. The number may be 0, indicating that no point type map element is identified within the preset map area. Wherein the spatial position of the point type map element should satisfy the following condition:
(1-threshold) X Ratio of ≤(X1-X min )/(X max -X min ) Less than or equal to (1 + threshold) X Ratio of ；
(1-threshold) Y Ratio of ≤(Y1-Y min )/(Y max -Y min ) Less than or equal to (1 + threshold value) Y Ratio of ；
Wherein X1 represents the abscissa of the point-like element, i.e., the amount of displacement of the point in the X-axis direction, Y1 represents the ordinate of the point-like element, i.e., the amount of displacement of the point in the Y-axis direction, X max Is the maximum X coordinate, X, of the minimum bounding rectangle min Is the minimum X coordinate, Y, of the minimum bounding rectangle max Is the maximum Y coordinate, Y, of the minimum bounding rectangle min A minimum Y coordinate that is a minimum bounding rectangle; the X ratio is defined as (X-X) min )/(X max -X min ) The value, Y ratio, means (Y-Y) specified min )/(Y max -Y min ) The value is obtained.
Step S201, determining the minimum value N of the number of point type map elements according to the error case base and the point type map element standard base min And maximum value N max ；
Step S202, if the number N of point type map elements is greater than or equal to the minimum value N min And is less than or equal to the maximum value N max If so, judging that the result is correct;
step S203, if the number of the point type map elements is less than the minimum value N min Or greater than the maximum value N max If yes, the result is judged to be error; the decision rule refers to table 1:
TABLE 1
| Decision rule | The result of the judgment |
| Nmin≤N≤Nmax | Is accurate to |
| N＜NminOR N＞Nmax | Error(s) in |
Wherein N is min And N max The minimum value and the maximum value of the number of elements specified in the standard library and the error case library of the map elements are respectively represented.
Step S204, determining a judgment result according to the relationship between the legend element and the identification element under the legend element and the point type map element model;
specifically, the type of the element is a point type map element model constructed by automatically recognizing a point type map element using a computer, and is represented by T.
First, it is determined whether the type of an element matches the type specified by the element in the legend, and the determination rule is as shown in table 2 below:
TABLE 2
| Decision rule | The result of the judgment |
| Book (legend element) = True AND T (identification element) = T (legend element) | Correction of |
| Book (legend element) = True AND T (identification element) ≠ T (legend element) | Error(s) in |
| BoolT (legend element) = False | Correction of |
Wherein when Bool T (legend element) = True, indicating the presence of such an element in the legend; when Bool T (legend element) = False, this indicates that such an element is not present in the legend. If the map elements do not exist in the legend, the map elements belong to the problems such as the unnormalized quality of the map, and the map elements are not determined as the problem map according to the reasons. When Bool T (legend element) = False, this indicates that there is no legend element, and the type of default element indicates correct.
Step S205, determining a judgment result according to the relationship among the identification elements, the similar elements and the heterogeneous elements under the point type map element model;
specifically, by determining whether the type of the element is correct, the determination rule refers to table 3:
TABLE 3
| Decision rule | Determination result |
| T1 (identification element) = T1 (analogous element) | Correction of |
| T1 (identification element) ≠ T1 (homologous element) AND T1 (identification element) = T1 (heterologous element) | Error(s) in |
| T1 (identification element) ≠ T1 (homogeneous element)) AND T1 (identification element) ≠ T1 (heterogeneous element) | Manual judgment |
Wherein, when T1 (identification element) = T1 (any heterogeneous element), it is regarded that T1 (identification element) = T1 (heterogeneous element); when T1 (identification element) = T1 (any similar element), it is assumed that T1 (identification element) = T1 (similar element).
T1 (identification element) refers to a map element being determined at this time, T1 (homogeneous element) refers to a map element having the same type as the map element being determined, and T1 (heterogeneous element) refers to a map element having a different type from the map element being determined.
Step S206, according to the minimum outsourcing rectangle element, X Ratio of 、Y Ratio of And a threshold value, determining the judgment result.
Specifically, the spatial position of an element refers to the relative positional relationship of the spatial position of a dot type map element, which is represented by X and Y, with other map elements for reference. The decision rule is shown in table 4:
TABLE 4
Wherein, Y refers to the Y coordinate of the intersection point of the X-axis vertical line passing through the point and the designated element, X refers to the X coordinate of the intersection point of the Y-axis vertical line passing through the point and the designated element, bool value is True value and is positive number, bool value is False value and is negative number, X refers to the X coordinate of the intersection point of the X-axis vertical line passing through the point and the designated element, bool value is True value and is negative number, and X refers to the X coordinate of the intersection point of the X-axis vertical line passing through the point and the designated element max And X min Respectively refer to the maximum X coordinate and the minimum X coordinate, Y, of the minimum bounding rectangle max And Y min Respectively refer to the maximum Y coordinate and the minimum Y coordinate, X, of the minimum bounding rectangle Ratio of Means defined by (X-X) min )/(X max -X min ) Value Y Ratio of Means defined by (Y-Y) min )/(Y max -Y min ) The value is obtained. When Bool X1 And Bool X2 Is also False, and Bool Y1 And Bool Y2 Is False, the point type map element is completely overlapped with the map element for reference.
If all judgment results of the map elements are correct, judging the map elements to be correct; if any one of the map elements is judged to be wrong, the map element is judged to be wrong; if the judgment result is manual judgment, the map elements need to be manually judged, and the problem map judgment rule base is perfected according to the result of the manual judgment.
