A method for displaying real scene space by navigation map

Abstract

A method for displaying the real scene space on a navigation map. The data storage and processing method is as follows. The data part is entered from the outside. In order to solve the problem of excessive original data, data compression is required after data entry. The proposed method is here The basic idea of ​​the scheme is to reorganize and sort the original data, and it is necessary to ensure that the data is not damaged; the data mainly consists of two parts: the object model and the model texture; the object model is divided into two parts, one part is a separate model with no commonality, and the other part is There is a common model with commonality; the original vertex coordinates and texture coordinates are all stored by floating point numbers. The invention has the advantages of solving the problem of limited capacity of the storage medium by compressing the data, and improving the utilization rate of the storage medium. It improves the efficiency of the program in data reading, and is especially effective in guiding and prompting complex intersections. It is an indispensable real-scene display technology for future metropolitan navigation.

Description

technical field [0001] The invention relates to the field of navigation, in particular to a method for displaying a real real scene space on a navigation map. Background technique [0002] With the rise of the automotive electronics industry, car navigation systems have begun to come into people's sight. Car navigation system is a complex that provides drivers with services such as electronic maps, vehicle positioning, real-time voice guidance, and real-time screen guidance based on embedded hardware, global GPS positioning, and geographic information data. Although automotive electronic navigation products have been developed for decades, all areas of navigation have made unprecedented progress, such as the improvement of GPS accuracy, the rise of voice navigation, the application of positioning and locking technology, the application of dual-page technology, etc. , but in terms of map display, it is still limited to the basic drawing of points, lines, and planes, which is...
