A road surface drawing device is provided with: a road surface drawing unit (11) that irradiates a road surface with a road surface drawing pattern (P); an object identification unit (13) that identifies the object on the basis of the surrounding environment information from a detection unit (2) configured so as to detect an object present in a predetermined region; an angle calculation unit (14) that calculates a three-dimensional angle formed by a first point (X), which is an arbitrary point on the road surface on which the road surface drawing unit (11) irradiates the road surface drawing pattern (P), and a second point, which is an arbitrary point on the object; an illumination control unit (12) that controls the road surface drawing unit (11); the illumination control unit (12) changes the road surface drawing pattern (P) on the basis of the three-dimensional angle calculated by the angle calculation unit (14).

    路面绘制装置具备:路面绘制部(11),其向路面照射路面绘制图案(P);对象物确定部(13),其基于来自检测部(2)的周边环境信息,确定所述对象物,所述检测部构成为检测出存在于规定区域的对象物;角度计算部(14),其计算出所述路面绘制部(11)将所述路面绘制图案(P)照射至的路面的任意点即第一点(X)和所述对象物的任意点即第二点所构成的立体角度;照明控制部(12),其控制所述路面绘制部(11);所述照明控制部(12)根据由所述角度计算部(14)计算出的所述立体角度使所述路面绘制图案(P)变化。
