Detailed Description
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, but rather construed as limited to the embodiments set forth herein.
A first embodiment of the present application provides a data processing method, which is described below with reference to fig. 1.
As shown in fig. 1, in step S101, original geometric shape information of a plurality of stores included in a target object is obtained.
The target object may include the entire floor of a building, a site including a plurality of stores, or the like. For example, the first floor of a certain mall.
The original geometric shape refers to various polygons, such as a triangle, a rectangle, etc.
The original geometry information includes: the geometric line information of the original geometric shape and the geometric point information of the original geometric shape are formed; the geometric line information includes coordinate information of both end points of the line segment, and the geometric point information includes coordinate information of the geometric point. Wherein, the geometric point: point information representing a geometric shape, a plurality of geometric points, may constitute a geometric line. For example, if the geometric shape is a rectangle, the geometric points may refer to the four vertices of the rectangle. Geometric line: and line information representing a geometric shape, wherein a plurality of geometric lines can form a polygon to represent the shape of the shop.
Obtaining the original geometric information of the plurality of stores included in the target object may refer to obtaining the original geometric information of the plurality of stores included in the target object from the database. Data in the database are acquired through manual field acquisition, and due to the fact that the accuracy of the data acquired on the field is inaccurate, gaps and overlapping problems exist among the outlines of the shops and between the outlines of the shops and floors (as shown in fig. 2), the gaps and the overlapping problems need to be removed, and the display effect of the client side is consistent with the actual layout situation of the shops.
As shown in fig. 1, in step S102, a first geometric point information set and a geometric line information set of a store are obtained from the original geometric shape information of the store, and an association relationship between a geometric line and a geometric point, and between a geometric line and store identification information is obtained.
Splitting original geometric shape information to obtain geometric point information and geometric line information of each store, combining the geometric point information into a first geometric point information set, combining the geometric line information into a geometric line information set, and storing the association relationship between a geometric line and the geometric point, between the geometric line and store identification information.
The method for obtaining the information set of the first geometric point and the information set of the geometric line of the shop according to the original geometric shape information of the shop comprises the following steps of:
obtaining all geometric point information corresponding to the original geometric shape of the shop;
judging whether the geometric point is the last point corresponding to the original geometric shape of the shop or not, and if so, removing the geometric point to obtain the rest geometric points;
storing the rest geometric point information into a first geometric point information set and storing the association relationship between the shop identification information and the rest geometric points;
obtaining all geometric line information corresponding to the original geometric shape of the shop; each geometric line information contains two pieces of geometric point information representing end points;
judging whether the geometric line is a line segment formed by the last point and the first point corresponding to the original geometric shape of the shop, and if so, removing the line segment to obtain the remaining geometric line;
and storing the rest geometric line information into a geometric line information set and storing the association relationship between the shop identification information and the rest geometric lines.
Since the last point of the geometry points stored for each original geometry is repeated with the first point, the last point is removed to ensure that the geometry points in the set of geometry point information are not repeated. Similarly, since the line segment formed by the last point and the first point corresponding to the original geometric shape of the store is a point, the geometric line needs to be removed to obtain the remaining geometric lines, so as to ensure that the geometric lines in the geometric line information set are effective geometric lines. For example, if an original quadrilateral corresponds to 5 geometric points (point 0, point 1, point 2, point 3, point 4), and point 4 is the last geometric point, then point 4 is removed.
As an implementation manner, the first embodiment of the present application may further include: judging whether the original geometric shape of the shop is of a multi-surface type; if so, modifying the original geometric shape of the shop into a single-sided type to obtain the modified geometric shape of the shop;
the obtaining of all the geometric point information corresponding to the original geometric shape of the store includes:
obtaining all the geometric point information corresponding to the modified geometric shape of the shop;
the obtaining of all the geometric line information corresponding to the original geometric shape of the shop includes:
and obtaining all the geometric line information corresponding to the geometric shape of the modified shop.
If the original geometry of the store is a multi-polygon type (multi-polygon), the original geometry needs to be scattered to a single side (single-polygon) to obtain the modified geometry of the store, and then all the geometric point information and all the geometric line information corresponding to the modified geometry of the store are obtained.
As shown in fig. 1, in step S103, the geometric points are merged to update the association relationship between the geometric lines and the geometric points.
The geometric points are subjected to a merging process in order to remove gaps and overlapping portions between the original geometric shapes of the stores.
The merging the geometric points comprises the following steps:
and combining the geometric points with the distance between the geometric points smaller than a preset distance threshold value into one geometric point.
For example, if the preset distance threshold is 10cm, a plurality of geometric points with a distance between the geometric points being less than 10cm are merged into one geometric point, so that gaps and overlapping portions between partial shop outlines can be removed.
The merging of the geometric points with the distance between the geometric points smaller than the preset distance threshold into one geometric point and the updating of the association relationship between the geometric line and the geometric points includes:
traversing the first geometric point information set;
obtaining a first distance between the current geometric point and the temporary geometric point; the temporary geometric point is a geometric point of the first geometric point information set except the current geometric point and not marked as a geometric point to be removed;
judging whether the first distance is smaller than a preset distance threshold value or not;
if so, acquiring geometric line information corresponding to the temporary geometric point;
modifying the incidence relation between the geometrical line information corresponding to the temporary geometrical point and the temporary geometrical point into the incidence relation between the geometrical line and the current geometrical point, and adding the incidence relation between the geometrical line and the current geometrical point;
marking the temporary geometric points as geometric points to be removed.
The modifying the association relationship between the geometric line information corresponding to the temporary geometric point and the temporary geometric point into the association relationship between the geometric line and the current geometric point includes:
obtaining the coordinates of the current geometric point;
obtaining a coordinate index sequence number of a temporary geometric point in geometric line information corresponding to the temporary geometric point;
and modifying the coordinate corresponding to the coordinate index sequence number in the geometric line information into the coordinate of the current geometric point.
And the coordinate index serial number in the geometric line information corresponding to the temporary geometric point refers to the coordinate index position of the temporary geometric point in the corresponding geometric line information. For example, the geometric line information corresponding to the temporary geometric point includes coordinates of two end points, the temporary geometric point is the second end point of the geometric line, the coordinate index number of the temporary geometric point in the geometric line information corresponding to the temporary geometric point may be 1, and the coordinate index number of the first end point of the geometric line may be 0.
For example, the coordinates of the current geometric point A are (x) 1, y 1, ) The coordinate index number of the temporary geometric point in the geometric line information corresponding to the temporary geometric point is 1, and the coordinate corresponding to the coordinate index number 1 in the geometric line information is updated to the coordinate of the current geometric point, namely the temporary geometric pointThe coordinate of the second endpoint in the corresponding geometric line information is modified into the coordinate (x) of the current geometric point 1, y 1, )。
The increasing of the association relation with the geometric line in the current geometric point comprises the following steps:
adding an index serial number of geometric line information corresponding to the temporary geometric point in the attribute information of the current geometric point, and adding a coordinate index serial number of the temporary geometric point in the geometric line information corresponding to the temporary geometric point in the attribute information of the current geometric point; the index sequence number of the geometric line information corresponding to the temporary geometric point refers to an index sequence number of the geometric line information corresponding to the temporary geometric point in the geometric line information set.
For example, if the index number of the geometric line information lineA corresponding to the temporary geometric point in the geometric line information set is 5, the index number 5 is added to the attribute information of the current geometric point a, that is, the association relationship between the point a and lineA is established, and further, the coordinate index number of the temporary geometric point tempA in lineA is added to the attribute information of the point a, so as to determine the specific position of the point a in lineA.
As shown in fig. 3, it is a flow chart for merging geometric points.
When the geometric points are merged, some geometric points are far away from other geometric points and cannot be merged with other geometric points, and gaps or overlaps exist between the geometric line associated with the geometric points and the adjacent geometric lines of other geometric shapes (as shown in a in fig. 2), the geometric points and the geometric lines need to be merged to remove the gaps and overlapping parts between the original geometric shapes of the stores.
As an embodiment, the method further comprises:
removing the geometric point information to be removed from the first geometric point information set to obtain a second geometric point information set after removal;
and merging the geometric points and the geometric lines of the second geometric point information set, and updating the geometric lines and the association relations among the geometric points, the geometric lines and the shop identification information.
Removing the geometric point information to be removed from the first geometric point information set by adopting the following two ways:
the first way is to directly remove the geometric point to be removed from the first geometric point information set when the temporary geometric point is determined to be the geometric point to be removed.
The first mode is as follows:
storing the geometric point information to be removed into a list to be removed;
traversing the geometric point information set, judging whether the current geometric point is in a list to be removed or not,
and if so, removing the current geometric point information from the geometric point information set.

and merging the geometric points of the second geometric point information set with the vertical distance from the geometric line smaller than a preset distance threshold value onto the geometric line.
The merging, onto a geometric line, the geometric point of the second geometric point information set whose perpendicular distance from the geometric line is smaller than a preset distance threshold includes:
traversing the second geometric point information set and the geometric line information set;
when all the geometric points associated with the temporary geometric line are not merged with the current geometric point, the current geometric point does not belong to the temporary geometric line, and the current geometric point and the temporary geometric line do not belong to the same polygon, judging whether the vertical distance between the current geometric point and the temporary geometric line exceeds a preset distance threshold value or not;
if not, the current geometric point is merged to the temporary geometric line.
The merging the current geometric point to the temporary geometric line includes:
acquiring projection point information from a current geometric point to a temporary geometric line;
judging whether the geometrical shape of the shop formed after projection is an illegal figure or not according to the projection point information;
if not, obtaining the relation between a line segment formed by the current geometric point and the projection point and a geometric line to which the current geometric point belongs;
and if the relation between the line segment formed by the current geometric point and the projection point and the geometric line to which the current geometric point belongs is not intersected, updating the coordinate information of the current geometric point into the coordinate information of the projection point.
Illegal graphics refer to graphics that are not polygons.
Fig. 4 is a flowchart for merging geometric points and geometric lines according to the first embodiment of the present application.
As shown in fig. 1, in step S104, the target geometric shape information of the plurality of stores included in the target object is obtained from the updated association between the geometric line and the geometric point and the association between the geometric line and the store identification information.
After the updated association relationship between the geometric line and the geometric point and the association relationship between the geometric line and the store identification information are obtained, the target geometric shape information of the stores included in the target object can be regenerated according to the association relationship.
