Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of a picture archiving method according to an embodiment of the present invention, as shown in fig. 1, including the following steps:
and 101, acquiring pixel coordinates of the touch point in the target map container.
The contact points are points generated after the user clicks on the map interface. In specific implementation, the map interface is clicked by a user through a mouse, a finger, an electronic pen, and the like, and in this embodiment, the map interface is mainly clicked by the mouse. The target map container comprises a pixel coordinate system and pixel points of the target map and pixel coordinates corresponding to each pixel point. The pixel coordinate is an offset generated after clicking the target map. The target map is a map currently used by the user. The user is an engineer of the target map project or a worker having the ability to configure, etc. The pixel coordinates of the touch point in the target map are actually the specific position of the touch point in the target map. The location of the touch point may be used to represent the location of the target marker in the target map. The target object may be a camera, a building, a road entrance, a service site, or the like, and in this embodiment, the target object is mainly a camera. Determining the pixel coordinates of the touch point in the target map container may also be referred to as determining the pixel coordinates of the target marker in the target map container. When the target map is used as a building map, the camera may be a camera provided in a building, and when the target map is used as a road map, the camera may be a monitoring camera provided on a road, or the like.
Specifically, when there is a touch point in the target map container, the pixel coordinates of the touch point relative to the target map container are correspondingly obtained according to the offset generated when the touch point is generated relative to the background of the target map.
And 102, calculating the actual longitude and latitude coordinates of the contact points in the target map according to the pixel coordinates.
The actual longitude and latitude coordinates are the longitude and latitude coordinates of the earth, and can also be called as geographical coordinates.
Specifically, after the pixel coordinates of the contact point in the target map container are obtained, the container point mark may be used to convert the pixel coordinates of the contact point in the target map container into the actual longitude and latitude coordinates of the earth. It should be noted that, when the pixel coordinates and the actual longitude and latitude coordinates are converted, the conversion is performed according to a preset scaling between the target map and the actual longitude and latitude of the earth.
And 103, selecting a preset identifier to render the contact based on the actual longitude and latitude coordinates.
The preset mark can be an icon, a picture, a symbol, a character and the like; for example, if the contact is to be rendered as a camera icon, the preset camera icon may be selected to render the contact.
Specifically, after the actual longitude and latitude corresponding to the contact point is determined, the contact point can be rendered according to the actual longitude and latitude corresponding to the contact point and according to the preset identification of the target marker, so that the target marker corresponding to the contact point and the position of the target marker in the target map container are obtained.
In the embodiment of the invention, the pixel coordinates of the contact in the target map container are obtained; calculating the actual longitude and latitude coordinates of the contact in a target map according to the pixel coordinates; and selecting a preset identifier which is preset based on the actual longitude and latitude coordinates to render the contact. According to the invention, the pixel coordinates of the contact points in the target map container are determined, the pixel coordinates are converted into the actual longitude and latitude coordinates, the contact points are rendered based on the actual longitude and latitude coordinates and the preset identification, and then the target label object can be rendered on the target map, so that a user can conveniently label the target label object which needs to be labeled on the target map according to the self requirement. And further improving the labeling effect of labeling the target label on the target map.
Referring to fig. 2, fig. 2 is a schematic flowchart of another map annotation method according to an embodiment of the present invention, and on the basis of fig. 1, before step 101, the method further includes:
Or, in step 204, if the contact point is already stored in the target map container, the step of acquiring the pixel coordinate of the contact point in the target map container is executed.
Specifically, when the user starts the target map, if the target map has been used before, the contact points may have already been saved in the target map container, that is, when the user uses the target map before, the user clicks the target map interface, so that the corresponding contact points are generated, and the contact points may also be rendered and saved. Therefore, each time the target map is started, it is necessary to determine whether the contact point already exists in the target map. If the object map container has no touch point, it indicates that the user did not click the object map interface before using the object map container, and thus no touch point is generated, or it may indicate that the user uses the object map for the first time. At this time, whether the target map interface generates a click instruction needs to be detected in real time, and when the target map interface is detected to have the click instruction, it can be shown that a user clicks the target map interface through a mouse, and an offset is generated according to the mouse relative to the background of the target map, so that a corresponding contact generated in the target map container can be determined. It can be said that the object map container creates a new touch point. As the user continues to click on the target map interface, the target map container will generate a corresponding number of touch points. After determining that the touch points already exist in the target map container, step 101 may be repeatedly performed to obtain the corresponding pixel coordinates of each touch point in the target map container. This facilitates the step 102 and 103 of rendering each contact.
Alternatively, when the user starts the target map, if there is a touch point already in the target map container, it indicates that the user has used the target map before, and the user clicks the target map interface of the target map to generate a touch point, and the touch point at this time may be referred to as a history touch point. If the object map container in the historical usage record corresponding to the object map has already recorded the touch point, step 101 may be performed directly to obtain the pixel coordinates of the historical touch point in the object map container. Step 102 and step 103 are executed again to render the historical contact, where the rendering process can be understood as a process of restoring the rendering process of the historical contact to obtain the rendering label of the historical contact. It should be noted that there may be one or more history contacts in the process, and when there are a plurality of history contacts, the step 101-.
In the embodiment of the invention, historical contact points in the target map container can be rendered, and contact points generated after the target map container is rendered can also be rendered, so that all contact points in the target map container can be rendered and recorded. The target marker corresponding to the historical contact and the contact generated later and the position of the corresponding target marker in the target map container can be combined by a user conveniently in the using process.
The target map may be started through a browser, or may be started through application software (APP).
Optionally, referring to fig. 3 and fig. 3, a flowchart of another method for icon annotation provided in the embodiment of the present invention is shown. On the basis of fig. 1, the method further comprises:
And 303, if the number of the existing contacts exceeds the preset number of the contacts, judging whether the existing contacts need to be cleared.
And step 304, if the existing contact points need to be cleared, clearing the existing contact points in the target map container.
The new contact is a contact newly generated after the target map is opened, and is not a contact existing before the target map container. The preset number of the contacts is the preset maximum number of the contacts. The number of the existing contacts is the number of the contacts actually existing in the target map container.
Specifically, after the target map is opened, when the user clicks the target map interface each time, once a new contact is generated, the number of existing contacts in the target map container needs to be calculated, and whether the number of contacts actually existing in the target map container exceeds the preset maximum number of contacts is judged. If the number of the contacts actually existing in the target map exceeds the preset maximum number of the contacts, the number of the contacts in the target map container is excessive, when the contacts are rendered, the corresponding target markers are excessive, the corresponding storage number is also relatively excessive, when the contacts are displayed on the background of the target map, the displayed target markers on the target map interface are too many, dense and numb, influence on appearance is caused, and the contacts are inconvenient for a user to view. Moreover, when the target map is changed to the use scene, the reusability of the target map is low. This may reduce the usability and the like of the target map. At this time, it is necessary to determine whether or not the existing contact of the target map container needs to be deleted, that is, whether or not the history contact needs to be deleted. And when the user determines to delete the historical contact, directly deleting the data corresponding to the existing contact. When the existing contact in the target map container is deleted, step 202 is executed to detect whether the target map container generates a new contact.
Further, when the user determines that the existing contact of the target map container does not need to be deleted, the offset generated based on the point clicking the target map interface relative to the background of the target map can be obtained, that is, the corresponding pixel coordinate of the new contact in the target map container is directly obtained, and the pixel coordinate of the contact in the target map container is converted into the actual longitude and latitude coordinate of the earth through the contexturpoin ToLatLng (container point mark). And rendering the new contact according to the actual longitude and latitude coordinates.
In the embodiment of the invention, the number of the existing contacts in the target map container can be detected in real time, the number of the existing contacts is compared with the preset maximum number of the contacts, and if the number of the existing contacts exceeds the preset maximum number of the contacts, the existing contacts of the target map container can be eliminated, so that the number of the contacts of the target map container can be reduced, and the use performance of the target map can be improved.
Optionally, referring to fig. 4 and fig. 4, which are schematic flow diagrams of another map annotation method provided by an embodiment of the present invention, on the basis of fig. 1, before step 101, the method further includes:
And step 402, taking a preset target picture as a new map background of the target map according to the operation instruction.
The operation instruction is a preset instruction used for executing the change of the background of the target map. The operation instruction can be triggered by clicking a corresponding operation frame on the target map interface by the user. The preset target picture is a preset user-defined picture which can be used as a map background. The custom pictures can be stored in the picture database, and the number and the types of the custom pictures can be multiple, so that the requirements of users on map backgrounds can be met in different use scenes, and the visual effect is enriched. The user can select the required picture to generate a new map background according to the using scene to replace the currently used map background of the target map.
Specifically, when the target map is configured, the background of the target map can be replaced by using a preset target picture according to the needs of the use scene of the target map, so that different needs are met. The background of the target map is replaced when the target map is installed and configured. For example, company a develops a certain target map project, the target map project is mainly served by a public security department or a traffic management department, and when the public security department or the traffic management department uses the target map, engineers of the target map project of company a or workers with configuration capability can be required to set corresponding target map backgrounds for the departments according to the use scenes of the target map. For example, when the target map is used as a road map, a preset road background picture may be used as a background of the target map. When the target map is used as a building map, a preset building picture can be used as the background of the target map.
For example, if the target object to be marked in the target map is a camera, when the target map is used as a building map, the camera may be a camera arranged in a building, so that the user can mark each camera on the building map to a corresponding position. When the target map is used as a road map, the cameras can be monitoring cameras arranged on the road, so that a user can mark each camera to a corresponding position on the building map. Therefore, the user can intuitively know the position of each camera in the target map.
It should be noted that, the user-defined picture is used as the map background of the target map, which does not affect the map function of the target map, and is only convenient for the user to use or for the user to enrich the visual effect of the target map when using the target map.
It should be noted that, the target map has many usage scenarios, the tile display of the open source map is the same, and the displayed map background is single and not in line with the actual usage situation in different usage scenarios.
In the embodiment of the invention, the user-defined picture can be selected to be used as the map background of the target map according to different use scenes of the target map, so that the visual effect can be enriched, the use scenes can be met, and the characteristics of the map are reserved.
Optionally, after the preset identifier is selected based on the actual longitude and latitude coordinates to render the contact, the method further includes:
and displaying the preset identification corresponding to the rendered contact on the new map background of the target map.
And the new map background is the map background which is replaced when the target map is configured.
Specifically, after the touch point rendering is completed, the rendered corresponding preset identifier may be directly displayed on the new map background of the target map, so that the user may know the position of the rendered touch point and the specific position of the rendered touch point in the target map, and may visually know the type of the rendered object. It should be noted that each contact in the target map container has a binding relationship with the preset identifier displayed on the new map background of the target map, and as long as any one of the contact in the target map container or the preset identifier displayed on the map background of the target map is cleared, the corresponding other contact will also be cleared.
In the embodiment of the invention, the rendered touch points can be displayed on the background of the target map by corresponding preset marks and further displayed on the interface of the target map, so that the user can watch the touch points conveniently.
Optionally, the pixel coordinates of the target map container correspond to the pixel coordinates of the new map background.
Specifically, when the pixel coordinates of the target map container correspond to the pixel coordinates of the new map background, the positions of the touch points in the map container and the positions of the corresponding touch points in the new map background are displayed, so that when the touch points are rendered, the touch points in the target map container can be displayed on the corresponding new map background, and the position offset during touch point rendering is avoided. The pixel coordinates of the target map container are scaled the same as the pixel coordinates of the new map background. More specifically, the pixel coordinates of the touch point in the target map container correspond to the actual longitude and latitude coordinates of the earth according to a certain scaling ratio. And the pixel coordinates of the new map background correspond to the actual longitude and latitude coordinates of the earth according to a certain scaling.
When the target map background does not need to be replaced, the pixel coordinates of the target map container correspond to the pixel coordinates of the map background currently used by the target map. The pixel coordinates of the map background currently used by the target map are also corresponding to the actual longitude and latitude coordinates of the earth according to a certain scaling.
In the embodiment of the invention, the pixel coordinates of the target map container correspond to the pixel coordinates of the target map background and the actual longitude and latitude coordinates of the earth, so that the contact can be accurately marked and displayed, and the accuracy of contact rendering is further improved.
