Trajectory data processing method and device, storage medium and equipment

Abstract

The invention discloses a trajectory data processing method and device, a storage medium and equipment, and belongs to the technical field of networks. The trajectory data processing method comprisesthe following steps: acquiring trajectory data in a target geographic range, wherein the trajectory data comprises moving trajectories of a plurality of moving objects; generating a feature map layerof the trajectory data, wherein the feature map layer at least comprises a trajectory flow map layer, a moving speed map layer and a traffic direction map layer; performing fusion processing on each image layer included in the feature image layer, and displaying a fused feature image layer; and when a selection instruction for any pixel position on the fusion feature layer is obtained, displayingthe track flow at the pixel position, and the moving speed and the passing direction of the moving object. According to the trajectory data processing method, attribute information of multiple dimensions such as flow, speed and direction, is comprehensively considered in the trajectory modeling stage, and the motion mode of the moving object in the real world can be accurately mined, and the subsequent trajectory mining effect can be improved, and in addition, visual analysis can be carried out on the fused feature map.

Description

technical field [0001] The present application relates to the field of network technology, and in particular to a trajectory data processing method, device, storage medium and equipment. Background technique [0002] Trajectory data refers to the data information formed by sampling the motion process of one or more moving objects. Taking the road network as an example, the above-mentioned moving objects usually refer to vehicles. Nowadays, with the rapid development of network technology, collecting trajectory data and processing the collected trajectory data, that is, analyzing trajectory data through trajectory modeling methods, has become an in-depth study of trajectory data and mining moving objects in the real world. One of the important means in the sports mode. [0003] In related technologies, after the trajectory data is collected, simple processing is performed based on the trajectory data. For example, consider the trajectory as a 3D polyline formed by a moving...
