After state, needs the state of vector road and the vector road generating corresponding road conditions picture, then road conditions picture is sent to
Client.And the present invention is not necessarily to carry out the generation of road conditions picture in server end, it only need to be by the state of road id and road
(status) it sends, saves the processing time of server end, save the stream that server end sends road conditions picture to client
Amount.
In step S130 and step S140, in order to show that road conditions, client need to be arranged the face of each state of road
Color display mode.For example,<heavy congestion, brown shows>,<crowded, red display>,<smooth, green display>}, seriously gather around
Stifled, crowded and smooth each state for road, brown is shown, red display and the green color for being shown as each state are shown
Mode.
It is previously stored in the target area configuration information of whole roads in client, that is to say previously positioned every
Configuration information<road id of road, road native color value>.Client receives the traffic information data of server end return:
<road id, road status>, according to traffic information data<road id, road status>and the configuration of pre-set road
Information<road id, road native color value>, state rendering parameter is obtained, i.e. the corresponding of road native color value and road status is closed
System:<road native color value, road status>.According to<road native color value, road status>corresponding relationship and each
The color display mode of state, obtains the rendering parameter of road conditions: < road native color value, and brown shows/red display/green
Color shows >.
In step S150, the coloring process of road conditions rendering can establish, the unit of coloring process processing is one
The map opened, default is the primary colors for showing map.When there is road conditions to need to update, which receives rendering parameter, first
The sampling for carrying out map, gets the default color values of any pixel in current map, it is possible thereby to determine the sampled data
It is the road of which kind, and modifying sampled data is the data for finally needing to render, i.e., corresponding color is shown, to realize
The displays of road conditions.For example, the rendering parameter of road A is the<color value of pink colour, brown shows>, sample pink colour in the map
Color value when, it can the color value for determining the pink colour is the native color value of road A, then according to the rendering parameter by the road
Road A is rendered into brown, and user can determine that road A is heavy congestion according to the brown that road A is shown.It can use
GLSL (OpenGL Shading Language, shading language) method carries out the sampling of map, sweeps without carrying out individual element
It retouches, pixel acquisition speed is faster.
Client needs to show two figure layers of base map and road in traditional technology, needs to consume more resources.And this hair
Bright need to render a figure layer, it can complete the road conditions as being superimposed road figure layer on the base map in conventional method and show effect
Fruit.Due to render figure layer is few, reduce CPU (Central Processing Unit, central processing unit) and video memory etc.
