Abstract

The invention provides a road and building simulation modeling method based on real road surface data, the method comprising the following steps: S10, establishing a road network simulation model by using aerial photograph images; S20, generating building simulation models along the road by aerial survey data, and matching the building simulation models with the road network simulation models; S30, importing the digital elevation model data, so that the simulation model of the road network and the building conforms to the digital elevation model, and simulating the undulation condition of thereal pavement; S40, optimizing the overall appearance ratio of the model with reference to the real image to obtain the final model. According to the idea that the model attribute information groupware is modeled and matched with the space, by means of multi-source data fusion, the road model and the building model along the road are combined and matched with reference to the actual pavement, so that the model can show more details of the pavement, can restore the shape of the real street scene, undulation and other details, and can be better used in driving perspective simulation and other application scenes.

Description

【Technical field】 [0001] The invention relates to the technical field of road three-dimensional modeling, in particular to a road and building simulation modeling method based on real road surface data. 【Background technique】 [0002] The lane-level high-precision electronic map is a sub-meter-level precision map that mainly serves unmanned vehicles, or machine drivers. Compared with traditional navigation maps, high-precision electronic maps have higher real-time performance, accuracy in representing road surface features, and richness of semantic information. After obtaining the lane-level high-precision electronic map data, the driverless car can use high-precision positioning to match itself to the electronic map road network in real time. Real-time comparison enables route planning and avoidance of other traffic participants on the road. It enables unmanned vehicles to reduce their dependence on the on-board high-precision perception system, and is an essential part o...
