Problems solved by technology
[0004] However, when the communication between the vehicle and the cloud server is interrupted, the vehicle cannot know the location information of the relevant vehicle.
When the cloud server communication resumes, the vehicle receives the vehicle data of the relevant vehicle, and the animation showing the movement process of the relevant vehicle will show jumping changes, which will damage the smoothness of the animation rendering and display, and affect the user's viewing experience

The invention relates to a vehicle position information determination method, device and equipment for high-precision map drawing. The method comprises the following steps: collecting vehicle data from a latest historical time point of a data sending terminal before communication of the data sending terminal is interrupted; after the communication of the data sending terminal is recovered, collecting vehicle data from a plurality of different transition time points of the data sending terminal in a preset transition period; According to the vehicle data at the historical time point and the vehicle data at the plurality of different transition time points, determining the position information of the vehicle at a plurality of different prediction time points corresponding to the plurality of different transition time points. According to the scheme provided by the invention, multiple pieces of different position information of the vehicle can be determined at multiple different time points after the communication of the data sending terminal is recovered, and the information is utilized for the rendering work of subsequent transition animations, so that the smoothness and smoothness of animation rendering display of subsequent high-precision map drawing are improved.
Description
technical field [0001] The present application relates to the field of navigation technology, and in particular to a method, device and equipment for determining vehicle position information for high-precision map drawing. Background technique [0002] Among related technologies, the cloud control basic platform takes real-time dynamic data such as vehicles, roads, and the environment as the core, and combines the data of existing transportation-related systems and facilities that support cloud control applications to provide standardized services for intelligent networked vehicles and industry-related departments and enterprises. Common basic services. [0003] The cloud control basic platform can also be called a cloud server, which belongs to a kind of data sending terminal. The information of vehicles and other traffic participants can be collected and processed by roadside equipment and uploaded to the cloud server, and the information of vehicles and other traffic par...
