1. A method of generating a local map for travel control of a mobility, the method comprising:
loading the local map from an entire map stored in a memory, wherein the local map comprises at least a portion of the entire map;
acquiring a two-dimensional (2D) light detection and ranging (LiDAR) point data from a LiDAR mounted on the mobility;
acquiring a three-dimensional (3D) feature point data by receiving a front image of the mobility from a camera mounted on the mobility;
reducing a dimension of the 3D feature point data to a 2D feature point data;
binding the 2D feature point data to the 2D LiDAR point data; and
publishing the 2D feature point data bound to the 2D LiDAR point data on the local map.
