1. A vehicle having an image projection system for projecting an image on a road surface, comprising:
a body of the vehicle;
a window;
the image projection system comprises a plurality of projectors including an information image projector and a sensing light projector;
a camera configured to image the road surface outside of the vehicle; and
a controller configured to control the image projection system and the camera,
wherein the information image projector is configured to comprise:
a light source configured to irradiate a first light;
a light modulator configured to modulate the first light from the light source based on the information related to a vehicle input by the controller and generate an information image; and
a projection optical system configured to project the information image generated by the light modulator on the road surface,
wherein the sensing light projector is configured to project a second light for sensing on the road surface, and
wherein the second light for sensing is a grid-shaped image on the road surface, and intervals between the grids in the grid-shaped image of the second light for sensing on the road surface become wider as a distance from the vehicle increases.
