Abstract:
1. A method comprising: receiving optical distance data corresponding to opposite sides of an object along a road, wherein the optical distance data is generated by an optical distancing system and collected from the road; projecting the optical distance data onto an intermediate curved surface; translating the projected optical distance data onto a two-dimensional plane; receiving image data from at least one panoramic image; generating path side data based on a pixel value for a point of the translated optical distance data on the two-dimensional plane according to the image data; storing the path side data referenced to three-dimensional geographic coordinates; receiving map data from a map database, wherein the map data includes a plurality of nodes and a plurality of segments; selecting, using a processor, a segment from the plurality of segments in the map data; rotating, using the processor, the path side data based on the segment; and outputting the path side data overlaid on a portion of the map data.
