1. A method for acquiring coordinate system conversion information, the method comprising:
acquiring three-dimensional information including first lane information corresponding to a lane adjacent to a vehicle, through a LiDAR installed at the vehicle, and a surrounding image including second lane information corresponding to the lane, through a camera installed at the vehicle;
extracting the first lane information from the three-dimensional information;
fitting a plane based on the extracted first lane information; and
acquiring first coordinate system conversion information on the LiDAR and the camera by matching the second lane information with the first lane information using the fitted plane.
