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 objectives, technical solutions and advantages of the present application more clear, the present application will be further described in detail below through the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but 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 v...

Abstract

The present application discloses a vehicle control method and system based on polarized light, which are applied to the field of vehicle traffic. A moving polarized light spot is formed on the device, and the number of vehicles is at least one; the polarized light spot is monitored by a polarized light receiver, and the light spot information of the polarized light spot is obtained; the vehicle information is calculated according to the light spot information, and the vehicle information includes the vehicle motion information and vehicle information of each vehicle. Distance value from the vehicle; vehicle speed control for all vehicles based on vehicle information. The present application realizes the use of polarized light in vehicle speed measurement and distance measurement, realizes vehicle speed control, and improves traffic control capabilities.

Description

technical field [0001] The present application relates to the field of vehicle traffic, and in particular, to a method and system for vehicle management and control based on polarized light. Background technique [0002] At present, the application of polarized light is used for infrared fire detection, etc., which is filtered by an optical filter and only receives light of a specific frequency. [0003] The existing polarized light for ranging is calculated by sending polarized light and receiving reflected polarized light, which is the same as the principle of laser ranging. After the natural light passes through the polarizer, it changes into light with a certain vibration direction. This is due to the existence of a certain characteristic direction in the polarizer, called the polarization direction. The polarizer only allows vibrations parallel to the polarization direction to pass through, while filtering out light that vibrates perpendicular to the direction. [000...
