Embodiment Construction

[0027] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0028] Such as figure 1 As shown, the all-weather in-vehicle traffic signal environment system based on vehicle-road coordination includes a display screen and a data processing controller, the display screen is a foldable flexible LED transparent display screen, and the data processing controller includes an intersection identification and judgment module, Data access module, comparison and matching module and data processing module;

[0029] The intersection identification and judgment module is used to judge the relative position of the vehicle and the traffic signal light, and filter out the data information of the traffic signal light directly in front of the driving direction of the vehicle, and transmit the data information to the data access module; the intersection identification and judgment module adopts the vehi...

Abstract

The invention discloses an all-weather in-vehicle traffic signal environment system based on vehicle road coordination, in particular to the field of traffic signal recognition. The all-weather in-vehicle traffic signal environment system based on the vehicle road coordination includes a display screen and a data processing controller; the display screen is a foldable flexible LED transparent display screen; and the data processing controller includes an crossing recognition and judgment module, a data access module, a comparison and matching module, and a data processing module. The all-weather in-vehicle traffic signal environment system based on the vehicle road coordination uses the technologies of the vehicle road coordination technology, the 4G network technology, the Bluetooth connection technology, the cloud data technology and the like, and combines electronic devices such as a controller and a converter, and the connecting access of the signal light cloud data of the public security traffic system, so as to display the states of the signal light on the transparent display screen inside the vehicle after processing, which is convenient for the driver to clearly grasp the states of the signal lights.

Description

technical field [0001] The invention relates to the field of traffic signal recognition, in particular to an all-weather in-vehicle traffic signal environment system based on vehicle-road coordination. Background technique [0002] Traffic lights are the main infrastructure to indicate the passage of vehicles, and are generally set at intersections. There is a large amount of traffic at intersections, and the routes of vehicles are varied, so it is particularly important to follow the instructions of signal lights. However, in extreme weather such as rain, fog, severe smog, and being blocked by large vehicles, the driver's identification of signal lights is seriously disturbed. L1-L3 self-driving cars use camera image recognition in the signal light recognition method, and the recognition function is greatly reduced when the sunlight is strong. judgment. Contents of the invention [0003] The object of the present invention is to address the above shortcomings, and prop...
