Document Type and Number:
WIPO Patent Application WO/2024/029622
Kind Code:
A1
Abstract:
This road surface drawing device (10) for a vehicle projects an image based on a drawing pattern (P1) on a road surface. The road surface drawing device comprises: a road surface drawing unit (11) that irradiates a road surface (RS) with light (L1, L2, L3) to project an image (DSP) thereon; a control unit (12) that controls the projection of the image (DSP) by the road surface drawing unit (11); and an operation state acquisition unit (140) that acquires an operation state of the vehicle (100). Upon determining that the operation state is reverse operation, the control unit (12) controls the road surface drawing unit (11) in a reverse mode. Upon determining that the operation state is not reverse operation, the control unit (12) turns off the road surface drawing unit (11).
