A road data processing method and related apparatus

By setting attribute change points and sampling points in the electronic map, an optimization function is constructed to adjust the road width, which solves the problem of inaccurate display caused by fixed road width in electronic maps. This achieves accurate display of road width changes with the number of lanes, thus improving the display accuracy of electronic maps.

AI Technical Summary

Technical Problem

In non-high-definition electronic maps, roads are of uniform width, which fails to accurately reflect the actual road conditions, resulting in a display that is not close to reality and affecting the user experience.

Method used

Set attribute change points along the road line, sample N sampling points, construct an optimization function to adjust the road width to match the change in the number of lanes, form road shape parameters, and display the road width as the number of lanes changes.

Benefits of technology

The accuracy of road display on electronic maps has been improved, and road width has been made to vary with the number of lanes, making it more consistent with actual conditions and enhancing the user experience.

Abstract

The application discloses a road data processing method and related device, N sampling points are sequentially sampled on a road line according to road direction, and at least one non-attribute change point is included between two adjacent attribute change points. The attribute change point as the sampling point carries lane change information, which identifies the increase or decrease number of the lane at the attribute change point relative to the adjacent non-attribute change point. An optimization function is constructed based on the road width corresponding to the adjacent sampling points. In the data compilation process, the width difference between the attribute change point and the adjusted road width of the adjacent sampling point after the road width of the sampling point is adjusted based on the optimization function can conform to the difference in the number of lanes, so as to form a road shape parameter and display the road in an electronic map. When the number of lanes of a road changes, the corresponding lane width can also increase or decrease with the change in the number of lanes, effectively improving the road display precision of the electronic map.
