High-precision map data rendering method, device and equipment and computer program product

Abstract

The invention discloses a rendering method, device and equipment for high-precision map data, and a computer program product. The method comprises the following steps: acquiring elevation data and lane line data of a road; calculating slope data of the road according to the elevation data of the road; correcting the elevation data of the road according to the slope data of the road to obtain the corrected elevation data of the road; smoothing the lane line data according to the corrected elevation data of the road to obtain smoothed lane line data; and rendering high-precision map data according to the corrected elevation data of the road and the smoothed lane line data to obtain a rendered high-precision map. According to the method, the elevation data is corrected by using the road slope data, so that the accuracy of the elevation data is effectively improved, and data deviation caused by factors such as sensor errors is reduced. By smoothing the lane line data, noise and abrupt change are eliminated, so that the lane line data better conforms to actual road conditions.
