In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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 some, but not all, embodiments of the present invention. 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.
The traditional grid tile map has the same theme displayed at different levels, so that the map theme can be known only by one screenshot during display, and the vector tile map supports independent rendering of map elements such as buildings, roads, POIs, boundaries and the like, so that the style designs displayed at different map levels are different, and the style of the corresponding theme cannot be clearly displayed by a single screenshot. Specifically, the embodiment of the invention dynamically intercepts rendering pictures at all levels of visual angles from the vector map, and synthesizes the rendering pictures intercepted at all levels of visual angles into a dynamic picture, thereby realizing a dynamic screenshot method which is convenient to implement and high in running efficiency based on vector map rendering. By adopting the method, a dynamic graph (such as a GIF graph) can be finally generated, and the problem that the design of the theme style cannot be completely understood by a single screenshot is solved. The dynamic screenshot method based on vector map rendering provided by the invention will be explained and explained in detail through specific embodiments.
Fig. 1 shows a flowchart of a dynamic screenshot method based on vector map rendering according to an embodiment of the present invention. As shown in fig. 1, the dynamic screenshot method based on vector map rendering provided by the embodiment of the present invention includes the following steps:
step 101: intercepting rendering pictures of each level visual angle of the vector map;
in this embodiment, in order to solve the problem that a single screenshot in the prior art cannot completely know the theme pattern of the vector map, the embodiment adopts a processing mode of intercepting rendering pictures of the vector map at each hierarchy view angle, so that the intercepted rendering pictures at each hierarchy view angle of the vector map can be automatically obtained, and further, the purpose of knowing the theme patterns at different hierarchy view angles from one rendering picture can be achieved by combining with a processing mode of synthesizing the rendering pictures intercepted at each hierarchy view angle into a dynamic picture.
In this embodiment, each hierarchical perspective may be a hierarchical perspective depending on each map element, which is obtained from each map element. The map elements here refer to: the map data includes element information such as country, city, county, region, road surface, sea, building, green space, and the like. Accordingly, the respective hierarchical viewing angles may be a national level viewing angle, a city level viewing angle, a county level viewing angle, a district level viewing angle, a road surface level viewing angle, an ocean level viewing angle, a building level viewing angle, a greenbelt level viewing angle, and the like.
Step 102: and synthesizing the rendering pictures intercepted at the various hierarchical visual angles into a dynamic graph.
In this embodiment, rendering pictures cut at each level view are synthesized into a dynamic graph, so that the purpose of understanding theme styles of different levels of views of a vector map from one rendering picture is achieved.
In this embodiment, the dynamic graph in the GIF format may be used, and the GIF format is characterized by high compression ratio and small disk space occupation, so that the image format is widely used. The GIF format animation can store a plurality of still images at the same time to form continuous animation, so that the animation becomes one of a few formats supporting 2D animation.
For example, rendered pictures at the national level view angle, the urban level view angle and the building level view angle can be sequentially captured, and then the rendered pictures at the level view angles are synthesized into a dynamic picture, so that the purpose of simultaneously knowing theme rendering styles of the national level view angle, the urban level view angle and the building level view angle from one rendered picture is achieved.
According to the technical scheme, the dynamic screenshot method provided by the embodiment of the invention intercepts the rendering pictures of the vector map at all levels of visual angles and synthesizes the rendering pictures intercepted at all levels of visual angles into the dynamic map, so that the embodiment of the invention automatically acquires the intercepted rendering pictures of all levels of visual angles of the vector map in such a processing mode, achieves the purpose of knowing the theme styles of different levels of visual angles from one rendering picture, and well solves the problem that the theme styles of the vector map cannot be completely known by a single screenshot in the prior art.
Based on the content of the foregoing embodiment, in this embodiment, the intercepting of the rendered picture at each level view angle from the vector map specifically includes:
determining rendering completion time points of the vector map at each level visual angle;
and intercepting rendering pictures of each hierarchy view angle of the vector map according to the rendering completion time point of each hierarchy.
In this embodiment, when a vector map is subjected to image capture rendering at each hierarchy view angle, a key problem is to determine when to perform image capture operation at each hierarchy view angle, that is, to know rendering completion time of each hierarchy view angle. Therefore, in this embodiment, the process of capturing the rendered picture of the vector map at each level view includes two parts, the first part is to determine the rendering completion time point of the vector map at each level view, and the second part is to capture the rendered picture of the vector map at each level view according to the rendering completion time point of each level.
In the present embodiment, there are various implementations regarding the content of the first part determining the rendering completion time point of the vector map at each hierarchical view angle. For example, the first implementation: and setting a fixed rendering time delay for each level visual angle, and then carrying out screenshot processing on the corresponding level visual angle for each level visual angle after the fixed rendering time delay is finished. However, a problem may exist in this manner, that is, a fixed time delay is set for screenshot, and a problem may occur in that the screenshot is started when the map tiles of the corresponding hierarchy are not completely rendered, so that accuracy is reduced.
In addition, it should be noted that, in addition to the above processing manner of setting the fixed rendering delay for each hierarchical view angle, a second implementation manner may also be adopted: and setting different adaptive rendering time delays according to the data volume of each hierarchy visual angle. For example, for a national level viewing angle, the content of the displayed data is relatively large, and the adaptive rendering delay is set to be a little longer. For the building level view, the data content displayed is relatively small, and the adaptive rendering delay can be set to be shorter. It should be noted that, compared with the processing mode with fixed rendering delay, the processing mode can solve the problem of inaccurate screenshot opportunity existing in the fixed rendering delay to a certain extent.
In addition, in a more preferred processing manner, a third implementation manner may be further adopted: and determining rendering completion time points of the vector map at all the hierarchy view angles by acquiring a signal of map rendering completion under each hierarchy view angle and marking the signal. Compared with the method adopting fixed rendering time delay or adaptive rendering time delay mentioned in the first step and the second step. And thirdly, due to the processing mode, the rendering completion time point under each level visual angle can be accurately obtained, so that the accuracy of screenshot under each level visual angle can be greatly improved.
Based on the content of the foregoing embodiment, in this embodiment, the determining rendering completion time points of the vector map at each hierarchy view angle specifically includes:
after receiving an operation instruction entering any level visual angle, generating a marking value corresponding to any level visual angle according to the operation instruction;
generating a rendering instruction according to the operation instruction, packaging the marking value in the rendering instruction, and sending the marking value to a rendering processor so that the rendering processor performs rendering processing on the vector data of any level of visual angle;
receiving a trigger message which is sent by the rendering processor and used for informing that the vector data corresponding to the any level visual angle is rendered;
and judging whether the mark value carried in the trigger message is consistent with the generated mark value corresponding to any level visual angle, if so, determining that the current time point is the rendering completion time point of the vector map at any level visual angle.
In the present embodiment, a specific implementation manner of determining rendering completion time points of a vector map at each hierarchical view angle is given. Specifically, in this embodiment, after receiving an operation instruction entering each level of view, a marking value corresponding to the level of view is generated according to the operation instruction (for example, a variable is created to mark the current change of the level of view), then generating a rendering instruction according to the operation instruction, packaging the marking value in the rendering instruction and then sending the marking value to a rendering processor, so that the rendering processor performs rendering processing on the vector data of the hierarchy view angle, and after receiving a corresponding rendering instruction, the rendering processor reads and stores the tag value therein, and then, rendering processing operation is carried out on the corresponding level according to the rendering instruction, when the rendering processing is finished, a trigger message for informing that the vector data of the corresponding level view angle is rendered is sent, and the rendering processor reads the obtained mark value before the trigger message is placed. Therefore, after receiving a trigger message sent by the rendering processor for informing that rendering of the vector data corresponding to the view angle of any hierarchy is completed, it is determined whether a flag value carried in the trigger message is consistent with a generated flag value corresponding to the view angle of any hierarchy, and if so, it indicates that rendering of the corresponding hierarchy is completed, and at this time, it may be determined that the current time point is a rendering completion time point of the vector map at the view angle of the corresponding hierarchy.
The dynamic screenshot method provided in this embodiment is explained and explained in detail below with reference to fig. 2. As shown in fig. 2, when the view angle of the map changes (from one hierarchical view angle to another), a variable identified is created to mark the current change of the current hierarchical view angle, the tile data required by the current change is calculated by the vector tile layer, and then the map is loaded with the tile data. And after the data loading is finished, triggering a loadedData event, judging whether an animated mark is consistent with a mark transmitted before or not after the vector tile layer receives the event, if so, considering that the map rendering of the change is finished, and performing screenshot operation, otherwise, waiting for the triggering of the next event, and prompting abnormity if overtime, and needing screenshot again. In this way, the corresponding pictures are intercepted at the corresponding levels, and finally the GIF pictures are synthesized.
Based on the content of the foregoing embodiment, in this embodiment, the intercepting a rendered picture of each hierarchy view angle from a vector map according to a rendering completion time point of each hierarchy specifically includes:
and at the rendering completion time point of each level, respectively carrying out rendering picture interception of the corresponding level view angle on the vector map.
In this embodiment, it is to be noted that, after the rendering completion time point of each level is determined by the above embodiment, rendering pictures of corresponding level view angles are respectively captured from the vector map at the rendering completion time point of each level, so that a picture rendered at a corresponding level is accurately obtained, and the picture can accurately represent the style theme of the corresponding level.
Based on the content of the foregoing embodiment, in this embodiment, before performing rendered picture interception of each hierarchical view angle on a vector map, the method further includes:
determining a rendering picture intercepting sequence of each hierarchy visual angle of the vector map;
correspondingly, the intercepting of the rendered picture of each level view angle from the vector map specifically includes:
and intercepting the rendering pictures of each hierarchy view angle of the vector map according to the intercepting sequence of the rendering pictures.
In this embodiment, when the rendered pictures of each hierarchical view are captured, the capture processing may be performed according to a preset sequence. For example, the screen capture process may be performed in the order of a national level view, an urban level view, and a building level view. When screenshot processing is performed according to a set hierarchy sequence, it is required to judge which hierarchy view angle is entered one by one, and then render picture capture of each hierarchy view angle is performed on the vector map.
Fig. 3 is a complete dynamic screenshot flow based on vector map rendering. Fig. 3 illustrates a process of making screenshots in the order of a national level perspective, an urban level perspective, and a building level perspective. After a user sends a screenshot instruction, the map firstly animates to a national view angle and creates an animated mark, and then the required tile data of the current change is calculated by the vector tile layer, wherein the following processing procedures can be adopted when the required tile data is calculated by the vector tile layer: A. determining the trapezoidal bounding box range (also called a visible area) of the viewing window through the intersection point of the camera viewing cone and the XOZ plane; B. calculating the coordinates of the trapezoidal bounding box range; C. calculating pyramid tiles at four corners according to the coordinates of the trapezoidal bounding box range to obtain a tile pyramid bounding box range; D. and calculating the index of the current window tile according to the tile pyramid bounding box.
After the vector tile layer receives the event, whether an animated mark is consistent with a mark transmitted previously is judged, if so, the changed map rendering is considered to be finished, screenshot operation can be carried out, otherwise, triggering of the next event is waited, and abnormal screenshot is prompted if overtime occurs, and the screenshot needs to be carried out again. And after the screenshot operation is finished, judging whether the current view angle is a building level, if not, judging whether the current view angle is an urban view angle, if not, performing the screenshot operation of the urban view angle, and if true, performing the screenshot operation of the building level. If the current view angle is the building level, the screenshot operation is considered to be finished, and the intercepted pictures are combined into the final GIF picture according to the level data, so that the purpose of knowing the theme design of different view angles from one picture is achieved. When the cut pictures are combined into the final GIF picture according to the hierarchical data, the cut pictures may be tiled and combined in the order of the national-level view angle, the urban-level view angle, and the building-level view angle.
According to the above description, the present embodiment provides a dynamic screenshot method, which first obtains rendering screenshots of each hierarchy view angle, and then synthesizes the captured pictures into a final GIF picture according to hierarchy data, thereby achieving the purpose of understanding theme styles of different view angles from one picture. In addition, the embodiment also provides a dynamic screenshot method driven by the event based on the rendering end of the vector map, compared with a method for screenshot by setting a larger time delay, the dynamic screenshot method based on the rendering of the vector map greatly improves the screenshot accuracy by acquiring a signal of the rendering end of the map and driving the event (screenshot is performed by setting the time delay, and the screenshot is started when the map tile is not completely rendered, so that the accuracy is reduced), removes redundant waiting time, and runs efficiently and conveniently. Therefore, in the embodiment, the idea of the screenshot in each layer of view is matched with the mode of driving the dynamic screenshot in each layer of view according to the rendering end event, so that the problem that the theme style design cannot be completely known by a single screenshot is well solved.
