Problems solved by technology

[0002] Traditional markers, such as traffic signs, road guardrails, etc., have no contours on the plane patterns, plane symbols, and plane texts on them, so there is no outline for the light imaging of the imaging laser radar working band. The light reflection effect of the radar working band is poor and not sensitive enough, resulting in poor imaging effect or even no imaging content of imaging lidar on traditional markers

Abstract

The invention relates to the technical field of laser radar imaging, and discloses a marker and a functional coating. The marking object is a marking pattern, and the marking pattern has an imaging body, wherein the imaging body reflects the light output by the imaging lidar, or the imaging body reflects the light output by the imaging lidar and visible light; or the marking object includes a marking pattern and a pattern The background, marking pattern and / or pattern background has an imaging body, wherein the imaging body appears to reflect the light output by the imaging lidar, or the imaging body appears to reflect the light output by the imaging lidar and visible light, and the marking pattern and the pattern background are to the imaging laser Radar output reflects light to varying degrees, and the marking pattern and pattern background reflect visible light to varying degrees. In the working band of the imaging laser radar and the band of visible light, the difference between the reflectance of the marking pattern and the background of the pattern can be improved. Through the above method, the present invention can greatly improve the imaging contrast of the non-stereo marking pattern on the imaging lidar, and realize the imaging of the non-stereo marking pattern on the imaging lidar.

Description

technical field [0001] The invention relates to the technical field of laser radar imaging, in particular to a marker and a functional coating. Background technique [0002] Traditional markers, such as traffic signs, road guardrails, etc., have no contours on the plane patterns, plane symbols, and plane texts on them, so there is no outline for the light imaging of the imaging laser radar working band. The light reflection effect of the radar working band is poor and not sensitive enough, resulting in poor or even no imaging content for imaging lidar on traditional markers. Contents of the invention [0003] In view of this, the technical problem mainly solved by the present invention is to provide a marker and a functional coating, which can improve the imaging effect of non-stereo marker patterns on imaging lidar. [0004] In order to solve the above-mentioned technical problems, a technical solution adopted by the present invention is to provide a marker, which is a m...
