Deep-scene wide-angle sight distance screen for curve driving
The invention discloses a deep-scene wide-angle sight distance screen for curve driving, and relates to the technical field of curve driving safety. The invention provides a deep-scene wide-angle sight distance screen for curve driving, and the screen comprises a sight distance screen which is used for being disposed at the outer side of a road curve, and the sight distance screen protrudes in an arc-shaped manner in the direction close to the road curve; the width of the sight distance screen meets the following relational expression: # imgabs0 #, f is the focal length of the sight distance screen, R1 is the radius of the road curve, and S overtaking is the overtaking sight distance. The objective of the invention is to solve the problems that in the prior art, a convex mirror is used in a curve, and vehicle information behind the curve fed back by the mirror surface can be seen clearly only when a vehicle decelerates and is close; the actual distance can be amplified by multiple times, and the misjudgment of the distance is easily caused.
本申请公开了一种弯道行车用深景广角视距屏幕，涉及弯道行车安全技术领域。本申请提供一种弯道行车用深景广角视距屏幕，包括：视距屏幕，其用于设置在公路弯道的外侧，所述视距屏幕沿靠近公路弯道的方向弧形凸起；所述视距屏幕的宽度满足以下关系式：#imgabs0#其中，f为视距屏幕的焦距，R1为公路弯道半径，S超车为超车视距。旨在解决现有技术中弯道使用凸面镜，需要车辆降速且很近距离，才能看清镜面反馈的弯道背后的车辆信息；会把实际的距离放大很多倍，容易造成距离误判的技术问题。
