Create an OpenDrive file
WorldEditor supports reading standard vector data files (e.g. . SHP format) and converting directly to OpenDrive files after pre-processing and checking; WorldEditor also supports the loading of orthophoto images. It can manually sketch traffic signs information such as road boundaries, lane lines, and road connections at intersections, and then save them as OpenDrive files.OpenDrive files editing and saving
WorldEditor supports the templates of roads, lanes painting, intersection areas, road assistance objects, signal lights and traffic signs. The editing functions after selecting OpenDrive road subjects include node optimization, adjustment, road marking editing, as well as the creation or deletion before and after.After creating and editing OpenDrive files, the users can save the results as an OpenDrive file, or a selected part of the road as a separate OpenDrive file. During the process, apart from choosing the saved path and file name, the users can also decide whether the file needs to be re-projected to other coordinates.Compatible with 51Sim-One
51Sim-One supports importing OpenDrive files, which are created, edited and saved by WorldEditor, containing accurate 3D geometric information of the road network, as well as semantic information indicating speed limits. Capitalizing upon this information, 51Sim-One can create realistic virtual 3D scenes with location information, providing an environment for simulation testing.
As an application that integrates the function of generating, editing and visualizing HD map files, which are necessary for intelligent driving and intelligent transport systems, WorldEditor also supports online connection with traffic flow simulation software such as SUMO, to achieve 2D and 3D visualization of traffic flow simulation data of HD maps. It is capable of loading traffic trajectory data from third-party software such as VISSIM and dynamically displaying the vehicle’s trajectory. Meanwhile, WorldEditor can load remote sensing images and thematic maps, create large-scale urban building models, water systems, etc. on the basis of GIS vector data and, with multi-source heterogeneous data, represent a comprehensive 3D scenario composed of roads, surrounding buildings, and greenery.
