Traffic light recognizing device

Abstract

The invention discloses a traffic light recognizing device. The traffic light recognizing device is characterized by being used for collecting vehicle position information for a vehicle-mounted GPS module in real time. When a vehicle passes through a traffic light, an image collecting module is controlled to collect images, the collected images are provided for a traffic light recognizing module through an image processing module to be judged, the judgment results are returned to the vehicle-mounted GPS module, and the vehicle-mounted GPS module can control a GPS interface display module and sound countdown broadcasting module to give alarm to a driver according to judgment results. By means of the structure, the traffic light recognizing device has the advantages of being simple and reasonable in structure, converting traffic light signals into text images and sound-light signals, enabling a traffic light display interface to be more reasonable, being user-friendly in a sound alarm method, bringing convenience to an achromatopsia driver and a fatigue driver to accurately recognize the traffic light, enabling the driver to be safer and smoother in a driving process, especially fully utilizing the vehicle-mounted GPS module and reducing production cost.

Description

technical field [0001] The invention relates to the field of new technology application of automobiles, in particular to a traffic light identification device. Background technique [0002] With the continuous development of the economy, the transportation is more and more convenient, and more and more cars enter ordinary families, which makes people's quality of life continue to improve, but on the other hand, the number of cars on the road is increasing, and the distance between pedestrians and vehicles There were also some contradictions. Traffic lights have become a very important tool for traffic safety and traffic hubs. For drivers, especially color-blind or fatigue drivers, it is very dangerous to run a red light because they cannot distinguish the color of the traffic light when crossing a traffic light intersection. [0003] The structure of the current traffic light recognition device is composed of image acquisition, MCU microcontroller, image processing and voic...

AI Technical Summary

Problems solved by technology

Although the existing devices can recognize the color of traffic lights and broadcast voices, and are helpful to color-blind and fatigue drivers driving cars, image acquisition always requires real-time acquisition of front images during the entire driving process, and there is no reasonable voice Broadcast and traffic light display interface

Therefore, there will still be potential safety hazards for drivers using existing traffic light recognition devices.
