Abstract

The invention discloses a method for displaying compound information of a traffic signal light facing an LED dot matrix light source. The system receives the traffic information display control signal, extracts the dot matrix of traffic indication patterns and text characters; calculates the red, yellow and green classification chromaticity values ​​of the synthesized traffic signal dot matrix; calculates the dot matrix of the synthesized traffic signal dot matrix Density distribution; calculate the classification brightness of the synthesized traffic signal lattice; synthesize the composite information display characteristic value of the traffic signal lattice according to the parameters, and obtain the simulated image; use the visibility prediction algorithm to obtain the optimal simulated image, and use the optimal simulation The traffic signal dot matrix corresponding to the image is stored and displayed as a composite information display image. The invention can meet the demands of dynamic change and personalized traffic signal compound indication, can effectively solve the problem of color-blind people's effective identification of monochrome indicator lights, and is simple and efficient to implement.

Description

technical field [0001] The present invention proposes a display control method of traffic signal lamps, in particular, a method for display control of composite information of traffic signal lamps oriented to LED dot-matrix light sources. Background technique [0002] Traffic lights have a long history of use, also known as traffic lights, which are light and color signals that are alternately changed at a specified time, and are usually set at intersections or other special locations to assign the right of way to vehicle drivers and pedestrians , the traffic control facility that controls its movement and turning. Use red, yellow and green lights or supplemented by sound to instruct vehicles and pedestrians to stop, pay attention and move forward, and set them at intersections or other necessary locations. It is mainly divided into motor vehicle signal lights, non-motor vehicle signal lights, crosswalk signal lights, lane signal lights, direction indicator lights, flashing...
