Problems solved by technology

[0004] However, in the field of vehicle traffic, polarized light technology is only used on car lights, and in terms of distance measurement, it can only be used for a single vehicle, and it is impossible to realize an integrated detection system between vehicles and between vehicles and ground equipment. Unable to improve the ability of traffic control

Embodiment Construction

[0082] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, not to limit the present application.

[0083] The embodiment of the present application discloses a vehicle control method based on polarized light.

[0084] refer to figure 1 , the method includes:

[0085] S101, when the vehicle is driving on the road, the polarized light emitter installed on the vehicle continuously emits polarized light to form a moving polarized light spot on the road.

[0086] Among them, the polarized light transmitter has a polarizer, and there is a certain characteristic direction in the polarizer, which is called the polarization direction, and the polarized light transmitter is installed on each vehicle. Such as...

Abstract

The invention discloses a vehicle management and control method and system based on polarized light, and is applied to the field of vehicle traffic, and the method comprises the steps: when a vehicle runs on a road, continuously transmitting polarized light through a polarized light transmitter installed on the vehicle, and forming a moving polarized light spot on the road, the number of the vehicle being at least one; monitoring the polarized light spot through a polarized light receiver to obtain light spot information of the polarized light spot; obtaining vehicle information through calculation according to the light spot information, wherein the vehicle information comprises vehicle motion information of each vehicle and a distance value between the vehicles; and carrying out vehicle speed control on all vehicles according to the vehicle information. According to the invention, polarized light is used for vehicle speed measurement and distance measurement, vehicle speed control is realized, and the traffic control capability is improved.

Description

technical field [0001] The present application relates to the field of vehicle traffic, in particular to a polarized light-based vehicle control method and system. Background technique [0002] At present, the application of polarized light is used for infrared fire detection, etc., and it is filtered through an optical filter to only receive light of a specific frequency. [0003] Existing distance measurement using polarized light is calculated by sending polarized light and receiving reflected polarized light, which is the same principle as laser ranging. After the natural light passes through the polarizer, it is changed into light with a certain vibration direction. This is because there is a certain characteristic direction in the polarizer, called the polarization direction, and the polarizer only allows the vibration parallel to the polarization direction to pass through, while filtering out the light that vibrates perpendicular to the direction. [0004] However, ...
