Example one
Referring to fig. 1, the method for displaying the building height based on the two-dimensional map of the present embodiment includes the following steps:
step S110: drawing the projection of the building on a two-dimensional map by a two-dimensional drawing technology, and performing projection processing on the building to enable the building to present height; by utilizing the two-dimensional drawing technology, the information of the building does not need to be acquired in detail through the three-dimensional drawing technology, and the map is drawn through complex calculation, so that the height of the building on the map can be reflected. In the two-dimensional drawing, only the projection of the building is drawn on the plane of the two-dimensional map, and the building with the height can be presented by processing the projection of the building.
Step S120: when new height data of the building are obtained, changing height parameters of the building on the two-dimensional map, and reprocessing projection of the building to present a new height; in practical situations, the height of the building can be changed as required, such as the situation that the cover needs to be covered, and the height of the building needs to be increased. In the three-dimensional drawing, when a building changes, the changed building information needs to be collected again, and a new building is drawn again according to the changed building information, and in the process, the information collection is troublesome and complicated in calculation. Through the two-dimensional drawing technology, the building can be redrawn only by changing the height parameters of the building and processing the projection of the building again without complex calculation, and the calculated amount of a system is reduced.
Example two
Referring to fig. 2 and 3, a method for displaying building height based on a two-dimensional map in the present embodiment includes the following steps:
step S210: the projection 320 of the building 320 is drawn on the two-dimensional map by using a two-dimensional drawing technology, the projection 320 of the building 320 is extended in proportion to a set angle to form the drawn building 320, and the building 320 presents the height through the extension of the projection 320 of the building 320. The projection 320 of the building 320 is drawn on the two-dimensional map through a two-dimensional drawing technology, the projection 320 of the building 320 is extended to a certain length to a set angle according to a proportion according to the collected building height, the projection 320 of the building 320 can form the building 320 in the extending process, the information of the building 320 does not need to be collected in detail, the map is drawn without using a 3D drawing technology, the building 320 does not need to be drawn through complex calculation, and the building 320 with the display height can be shown on the two-dimensional map. The two-dimensional drawing technology is characterized in that an algorithm is compiled at a GIS server to produce building outlines and building heights, and then worker clients are issued to call the building outlines and the building heights in a service mode.
Step S220: when new height data of the building is acquired, the height parameters of the building 320 of the building on the two-dimensional map are changed, and the extending length of the projection 320 of the building 320 is changed, so that the building 320 presents the new height. In practical situations, the height of the building 320 may vary as needed, such as the need for a lid, the height of the building 320. In the three-dimensional drawing, when the building 320 changes, the changed building 320 information needs to be collected again, and a new building 320 is drawn again according to the changed building 320 information, and in the process, the information collection is troublesome and complicated in calculation. By the two-dimensional drawing technology, the height of the building 320 in the two-dimensional map can be changed only by changing the extension length of the projection 320 of the original building 320 according to the data change of the height of the building 320, namely only by changing the height data of the new building 320, and the redrawing of the building 320 can be realized without complicated calculation, so that the calculation amount of the system is reduced.

EXAMPLE III
Referring to fig. 4 and 5, the method for displaying the building height based on the two-dimensional map of the present embodiment includes the following steps:
step S410: a first projection 510 of a building is rendered on a two-dimensional map using a two-dimensional rendering technique, and a second projection 520, which is scaled down according to a building height setting, is rendered in the first projection 510 of the building, the building height being presented according to a ratio of the first projection 510 and the second projection 520.

For example, a building height of 100 meters, the second projection 520 is scaled down by 50% of the first projection 510; if the building height is 200 meters, the second projection 520 is reduced according to the proportion of 25% of the first projection 510; the building height is 300 meters, the second projection 520 is reduced by a proportion of 12.5% of the first projection 510. Building information does not need to be collected in detail, a map is drawn without using a 3D drawing technology, and the building can be displayed on the two-dimensional map and the display height can be drawn without complicated calculation.
Step S420: when new height data of the building is acquired, the first projection 510 of the building is not changed, and the second projection 520 of the building is drawn again according to the new building height in proportion to form a new building. In practical situations, the height of the building can be changed as required, such as the situation that the cover needs to be covered, and the height of the building needs to be increased. In the three-dimensional drawing, when a building changes, the changed building information needs to be collected again, and a new building is drawn again according to the changed building information, and in the process, the information collection is troublesome and complicated in calculation. Through the two-dimensional drawing technology, the second projection 520 of the building is modified only according to the change of the building height data, namely only new building height data is needed, the second projection 520 is modified according to a new proportion, the new proportion is obtained according to the new building height data, the height change of the building in the two-dimensional map can be realized, the building can be redrawn without complex calculation, and the calculated amount of the system is reduced.
Example four
Referring to fig. 6, the apparatus 600 for displaying building height based on two-dimensional map of the present embodiment includes:
the rendering unit 610: the system comprises a projection module, a display module and a control module, wherein the projection module is used for drawing a projection of a building on a two-dimensional map through a two-dimensional drawing technology and enabling the building to present height through projection processing on the building; the drawing unit 610 draws a map by using a two-dimensional drawing technique without acquiring information of a building in detail through a three-dimensional drawing technique and by performing complicated calculation, so that the building on the map can embody a height. In the two-dimensional drawing, only the projection of the building is drawn on the plane of the two-dimensional map, and the building with the height can be presented by processing the projection of the building.
The modification unit 620: and the height parameter of the building on the two-dimensional map is changed when new height data of the building is acquired, and the projection of the building is reprocessed to present a new height. In practical situations, the height of the building can be changed as required, such as the situation that the cover needs to be covered, and the height of the building needs to be increased. In the three-dimensional drawing, when a building changes, the changed building information needs to be collected again, and a new building is drawn again according to the changed building information, and in the process, the information collection is troublesome and complicated in calculation. The modifying unit 620 can redraw the building by changing the height parameter of the building and processing the projection of the building again through a two-dimensional drawing technology without complex calculation, thereby reducing the calculation amount of the system.
Specifically, the drawing unit 610 draws a projection of a building on a two-dimensional map by using a two-dimensional drawing technology, extends the projection of the building in proportion to form a drawn building according to a set angle, and makes the building show a height by extending the projection of the building. The drawing unit 610 draws the projection of the building on the two-dimensional map through a two-dimensional drawing technology, the projection of the building is extended to a certain length to a set angle according to a proportion according to the collected building height, the projection of the building can form the building in the extending process, the information of the building does not need to be collected in detail, the map is drawn without using a 3D drawing technology, the building is drawn without complex calculation, and the building with the display height can be shown on the two-dimensional map.
When the modification unit 620 detects that the data of the building height is changed, the extension length of the building outline is changed on the two-dimensional map to form a new building. In practical situations, the height of the building can be changed as required, such as the situation that the cover needs to be covered, and the height of the building needs to be increased. In the three-dimensional drawing, when a building changes, the changed building information needs to be collected again, and a new building is drawn again according to the changed building information, and in the process, the information collection is troublesome and complicated in calculation. The modifying unit 620 can change the height of the building in the two-dimensional map only by changing the extension length of the projection of the original building according to the data change of the building height, namely, only by changing the new building height data through the two-dimensional mapping technology, and can redraw the building without complex calculation, thereby reducing the calculated amount of the system.
In the current 3D map, when the viewing angle changes, the whole map changes with the change of the viewing angle, and the 3D engine technology is required to support the map, which requires complex calculation. In this embodiment, when the viewing angle of the two-dimensional map is changed, the aspect of the whole map is not changed, and only the deflection angle of the building is changed, so that the direction of the building on the two-dimensional map can be changed when the viewing angle of the two-dimensional map is changed in time.
Alternatively, the drawing unit 610 draws a first projection of the building on the two-dimensional map using a two-dimensional drawing technique, and draws a second projection reduced in a scale set according to the building height in the first projection of the building, and presents the building height according to a ratio of the first projection and the second projection. The drawing unit 610 draws a first projection of the building on a plane of the two-dimensional map by a two-dimensional drawing technique, and draws a second projection based on the first projection of the building according to the acquired building height, and the drawing of the second projection of the building is performed according to the first projection by scaling down, wherein the scale of the scaling down is set according to the acquired building height. For example, if the building height is 100 meters, the second projection is reduced by 50% of the first projection; if the building height is 200 m, the second projection is reduced according to the proportion of 25% of the first projection; the building height is 300 meters, and the second projection is reduced according to the proportion of 12.5 percent of the first projection. Building information does not need to be collected in detail, a map is drawn without using a 3D drawing technology, and the building can be displayed on the two-dimensional map and the display height can be drawn without complicated calculation.
When the modifying unit 620 obtains the new height data of the building, the first projection of the building is not changed, and the second projection of the building is drawn again according to the new building height in proportion to form a new building. In practical situations, the height of the building can be changed as required, such as the situation that the cover needs to be covered, and the height of the building needs to be increased. In the three-dimensional drawing, when a building changes, the changed building information needs to be collected again, and a new building is drawn again according to the changed building information, and in the process, the information collection is troublesome and complicated in calculation. The modifying unit 620 modifies the second projection of the building only according to the change of the building height data, that is, only according to new building height data, and modifies the second projection according to a new proportion obtained according to the new building height data through a two-dimensional drawing technology, so that the height change of the building in the two-dimensional map can be realized, redrawing of the building can be realized without complex calculation, and the calculated amount of the system is reduced.
