Technical Field

The invention relates to the technical field of traffic signs, in particular to a road anti-reverse sign.

Background

The traffic marking is one of road traffic signals, is used for controlling and guiding traffic, and has the main functions of separating traffic, channelizing level crossing traffic, indicating and predicting road conditions ahead, law enforcement and law-keeping basis. At present, the main traffic signs are plane symbols and graphics sprayed on the road surface, and are very easy to ignore, so that the reminding strength is insufficient. In order to compensate for the above-mentioned drawbacks, some road surfaces are provided with embossed deceleration strips to achieve forced deceleration, but these deceleration strips inevitably damage the running vehicle and cause an uncomfortable bumpy feeling.

The 3D stereograph is a novel painting mode, and the most special place compared with the common painting is that its perspective principle is different from that of the common painting. The normal drawing, the perspective arrangement of the picture does not refer to the viewpoint of the user's own station, the picture structure of the picture is only based on the perspective of the picture, the 3d stereo picture refers to the station viewpoint of the user, the whole picture structure takes the viewpoint of people as the visual origin, so that the 3d stereo picture not only is a picture but also becomes a real visual space, and the user can be integrated into the picture. The picture is stretched and deformed by the naked eye from other angles. With the aid of a similar principle, chinese patent CN 96123432.6 discloses a three-dimensional traffic sign having a logo pattern with a plurality of portions in contact with each other on a road surface, the brightness difference of each adjacent portion being 1-level or more munsell chroma values, so that the visible image appears as a three-dimensional image, however, the invention is not highly distinguishable in a special environment of rain, fog and snow, and is mainly based on the brightness principle, which makes it impossible to distinguish brightness differences when the ambient light is low.
