Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Fig. 1 is a flowchart of steps of a method for touch mapping a map area according to an embodiment of the present invention, where the method may be applied to a terminal, as shown in fig. 1, and the method may include:
step 101, monitoring a touch track of a user when a touch drawing instruction is received, and recording a start point position and an end point position corresponding to a line segment in the touch track as touch information data of the touch track.
When the user draws the map area through the touch sliding gesture, the touch track of the touch sliding gesture can be split into a plurality of line segments connected in front-back mode.
When the trigger button is detected to be clicked by a user, the touch drawing instruction is determined to be received, at this time, the existing gesture operation of the electronic map can be forbidden, the touch track of the user is monitored, when the touch information data of the touch track is recorded, the starting point position and the ending point position of each line segment in the touch track can be recorded according to the drawing sequence of the touch track, and the point position between the starting point position and the ending point position in the same line segment is not recorded, so that the recorded data quantity is reduced, and the conversion speed when the subsequent conversion is changed into longitude and latitude coordinates can be improved.
In the two adjacent line segments, the termination point of the former line segment and the start point of the latter line segment are the same point, so that the drawing graph formed by each line segment in the touch track is a closed graph.
In a specific embodiment, the monitoring the touch track of the user, and recording a start point position and an end point position corresponding to a line segment in the touch track as touch information data of the touch track includes:
when the touch track of a user is monitored, identifying line segments and curve segments in the touch track;
recording the starting point positions and the ending point positions of the line segments, converting the curve segments into a plurality of line segments, and respectively recording the starting point positions and the ending point positions of the line segments according to the sequence to obtain the touch information data of the touch track.
When the touch track of the user is monitored, whether the touch points in the touch track are positioned on the same straight line or not can be identified by utilizing a callback mode of the system, so that the line segments and the curve segments in the touch track are identified. For a line segment, only the starting point position and the ending point position of the line segment need to be recorded. And for the curve segment, the curve segment can be realized by a plurality of line segments according to the radian of the curve, namely, the curve segment is cut, the intersection point of two adjacent cut lines is used as the termination point of the former line segment and the start point of the latter line segment, and each cut line and the intersection point thereof form a plurality of line segments, so that the curve segment is converted into a plurality of interconnected line segments. When the data is recorded, only the starting point position and the ending point position of each line segment are required to be recorded, so that the recorded data volume is reduced.
When converting a curve segment into a straight line segment, determining an intersection point of two adjacent straight lines according to whether adjacent touch points in the curve segment are positioned on the same straight line or not, and taking the intersection point as a termination point of a previous line segment and a start point of a next line segment if the adjacent touch points are not positioned on the same straight line.
Taking the drawing graph in fig. 2 as an example, the drawing graph in fig. 2 is a graph of a region drawn by a user, and then the touch points a to B are line segments, only two points are recorded and connected, the touch points a to C are line segments, only two points are recorded and connected, the touch points B to C are curve segments, cutting lines are formed on the curve segments, the intersection points of the cutting lines are recorded, and then the intersection points are connected in sequence, so that the graph drawn by the user is obtained.
And step 102, converting the touch information data into a plurality of longitude and latitude coordinates.
And converting the recorded touch information data into longitude and latitude coordinates required for electronic map display by using a function. Because the recorded touch information data is only the initial point and the final point of the line segment in the touch track, when the touch information data is converted into longitude and latitude coordinates, only the recorded point is required to be converted, and the converted data quantity is reduced.
It should be noted that, the step 102 may be started after the step 101 is performed, or the step 102 and the step 101 may be performed in parallel, that is, after the start point and the end point of a line segment are obtained, the obtained point location may be converted into longitude and latitude coordinates, so as to increase the processing speed.
And 103, displaying the longitude and latitude coordinates on the electronic map, and closing the point positions corresponding to the longitude and latitude coordinates to obtain a drawn map area.
Displaying the converted longitude and latitude coordinates on an electronic map, and closing the points corresponding to the longitude and latitude coordinates back and forth, wherein the graph drawn by the user is displayed on the electronic map at the moment, so that the map area drawn by the user through touch is obtained.
The embodiment of the invention realizes that in the electronic equipment of an operation system such as an IOS (input/output) and the like, a specific graph (regular or irregular) area is defined in the electronic map by utilizing gestures such as touch and swipe, so that the drawing area can be displayed in the electronic map and can be sent to a server, the server can conveniently search and screen the drawing area for data, and the server can record the drawing area and be used for LBS (Location Based Service, location-based service). Or after the map area is drawn, more flexible functions can be realized on the map area, such as hiding the map area according to a user instruction.
According to the method for drawing the map region by touching, when the touch drawing instruction is received, the touch track of a user is monitored, the initial point position and the end point position corresponding to the line segment in the touch track are recorded and used as touch information data of the touch track, the touch information data are converted into a plurality of longitude and latitude coordinates, the longitude and latitude coordinates are displayed on the electronic map, the point positions corresponding to the longitude and latitude coordinates are closed, and the drawn map region is obtained.

The gesture monitoring view is a mask view, preferably a transparent view, that is, the gesture monitoring view is preferably a transparent mask view, so that the gesture monitoring view is not perceived by a user. The display size of the gesture monitoring view is the same as that of the electronic map, so that touch information data can be accurately recorded, and the point on the transparent monitoring view can be more conveniently converted into longitude and latitude coordinates on the electronic map without correction operation. If the display size of the gesture monitoring view is the same as the display size of the electronic map, a correction operation is required.
A trigger button can be provided on the display interface of the electronic map, when the trigger button is detected to be clicked by a user, the touch drawing instruction is determined to be received, and then a gesture monitoring view is added on the electronic map.
Step 302, when the gesture monitoring view monitors the touch track of the user, recording a start point position and an end point position corresponding to a line segment in the touch track as touch information data of the touch track.
The touch track of the user is monitored through the gesture monitoring view, so that the touch signal is isolated from the electronic map, the conflict between the direct operation of the user on the electronic map and the existing gesture operation of the electronic map is avoided, and the user experience is improved.
Step 303, converting the touch information data into a plurality of longitude and latitude coordinates.
And 304, displaying the longitude and latitude coordinates on the electronic map, and closing the point positions corresponding to the longitude and latitude coordinates to obtain a drawn map area.
According to the method for drawing the map region by touching, when the touch drawing instruction is received, the gesture monitoring view is added to the electronic map, when the touch track of the user is monitored through the gesture monitoring view, the starting point position and the ending point position corresponding to the line segment in the touch track are recorded and used as touch information data of the touch track, the touch information data are converted into a plurality of longitude and latitude coordinates, the longitude and latitude coordinates are displayed on the electronic map, the points corresponding to the longitude and latitude coordinates are closed, the drawn map region is obtained, the touch signal is isolated from the electronic map through the gesture monitoring view, the conflict between the operation of the user on the electronic map and the existing gesture operation of the electronic map is avoided, and the user experience is improved.
On the basis of the above technical solution, after recording the start point and the end point corresponding to the line segment in the touch track as the touch information data of the touch track, the method further includes:
closing the ending point and the starting point of the touch track to obtain a closed line segment;
and determining a user drawing graph according to the closed line segment and the touch track, and displaying the user drawing graph on the gesture monitoring view.
When the gesture monitoring view monitors that a user starts touching the screen, the initial touch point is taken as a starting point of the touch track, when the user's finger is monitored to leave the screen, the touch point when the finger leaves the screen is determined to be a termination point of the touch track, and a straight line is used for connecting the termination point and the starting point, so that a closed line segment is obtained. The touch track and the closed line segment form a user drawing graph, and the user drawing graph is displayed on the gesture monitoring view, so that the complete user drawing graph can be displayed, a user can intuitively know a map area to be drawn, and user experience is improved.
On the basis of the technical scheme, after the drawn map area is obtained, the method further comprises the following steps: the gesture monitoring view is removed. After the map area is drawn, the gesture monitoring view is removed in time, so that an operation signal of a user on the electronic map can be received, and a response is given in time.
Fig. 4 is a flowchart illustrating steps of a method for touch mapping a map area according to an embodiment of the present invention, where the embodiment may cancel a part of a track that has been mapped and redraw a corresponding track based on the above embodiment. As shown in fig. 4, the method may include:

Step 403, when receiving the revocation instruction, determining a line segment to be revoked according to the revocation start point and the revocation end point in the revocation instruction.
A cancel button may be provided on the map area rendering interface for receiving a cancel instruction from the user. When the user finger is monitored to leave the screen and the leaving time is within the preset time, if the user is detected to click the revocation button, a revocation instruction is received, the starting point of the last line segment can be determined according to the revocation instruction, and the revocation ending point is the ending point of the last line segment. Or when the user finger is monitored to leave the screen and the leaving time is within the preset time, if the user is detected to click the revocation button, the user can be prompted to give the revocation start point and the revocation end point through touching, so that a revocation instruction comprising the revocation start point and the revocation end point is received, the line segment between the revocation start point and the revocation end point is determined to be the line segment to be revoked, and the line segment to be revoked can be one or more line segments.
