DEVICE FOR GENERATING COLOR MAP FORMED ON BASIS OF GPS INFORMATION AND LIDAR SIGNAL, AND CONTROL METHOD FOR SAME

Document Type and Number:

WIPO Patent Application WO/2021/221334

Kind Code:

A1

Abstract:

Provided is a color map generation method for forming accurate color map information by matching color information and obstacle information for each pixel. The color map generation method according to an embodiment comprises the steps of: receiving a GPS signal and forming GPS data; converting a plurality of GPS coordinates included in the GPS data into image pixel coordinates; matching the image pixel coordinates with the GPS data and color information corresponding to the plurality of GPS coordinates; clustering the image pixel coordinates on the basis of the positions of the Lidar coordinates respectively corresponding to the plurality of GPS coordinates; and forming color map data corresponding to the GPS data on the basis of the clustered image pixel coordinates.
