Vehicle driving trajectory rendering method and device, equipment and storage medium

Abstract

The invention provides a vehicle driving trajectory rendering method and device, equipment and a storage medium. The method comprises the steps of determining the spatial complexity of roads accordingto the distance between the roads in a road network; according to the spatial complexity of the roads, determining at least one target area; according to the spatial complexity of the roads in each target area, determining the road network complexity of the target area; matching target trajectory points with the roads to obtain a target matching road between any two adjacent target trajectory points; determining the matching complexity of any two adjacent target trajectory points according to the target matching roads; determining the connected road network complexity of any two adjacent target trajectory points according to the road network complexity of any two adjacent trajectory points or the target area where the target matching roads are located; and rendering target vehicle drivingtrajectories according to the matching complexity and the connected road network complexity. According to the method, on the premise of reducing the rendering disorder degree, the large-scale vehicledriving trajectories are rendered really.

Description

technical field [0001] The present application belongs to the technical field of the Internet, and in particular relates to a rendering method, device, equipment and storage medium of vehicle driving tracks. Background technique [0002] Vehicle trajectory is one of the most important data inputs in current map data analysis and production. For example, real-time road condition analysis based on real-time vehicle trajectories, discovery of road opening and closure, and new road discovery based on vehicle trajectories. The rendered vehicle trajectory can intuitively display the real vehicle path on the road, and by performing different color mapping on the trajectory during the rendering process, it can also intuitively display different attributes such as speed and accuracy of the trajectory. [0003] Existing vehicle trajectory rendering methods generally include direct rendering and abstract rendering. Direct rendering refers to directly using the continuous track points...

AI Technical Summary

Problems solved by technology

However, in the case of large-scale trajectory data and large differences in trajectory quality in the direct rendering method, the results often appear messy and poor user experience

At the same time, in the context of a relatively complex road network, the directly rendered trajectory often cannot truly reflect the real situation of vehicles driving, nor can it be used to reflect the real traffic conditions of the road.

The abstract rendering method only shows the statistical results of large-scale trajectories and lacks the original detailed information of the trajectories, which is not conducive to intuitive road traffic status analysis based on the original vehicle trajectories.
