Embodiment

[0020] A system for identifying traffic lights while a vehicle is running, comprising the following steps:

[0021](1) Image collection: Install a camera on the roof or inside the car to collect real-time images of the front of the car. The specification of the camera is a car video recorder with a color display, which can record and watch immediately. The lens angle is 90 degrees, and the shooting file format is AVI format for video, JPG format for photos; can be connected to computers, navigators, and mobile devices to play at any time, supports frame rate adjustment to save space or record the best quality images, with digital components, can directly transfer digital images through computer ports or Standard equipment transfers to the computer;

[0022] (2) Image preprocessing: After the image is collected, the image is digitized through the inherent analog-to-digital conversion part of the camera, and input to the microprocessor through the port. Because the camera moves ...

Abstract

The invention discloses a traffic light identification system in the driving process. The system comprise the steps of image collection, image preprocessing, traffic light positioning, color discrimination, color space conversion, countdown display and voice prompt. The system can be used to automatically discriminate a traffic light in front, and thus, prompts a driver, and enables enough response time; and the driver can take measures timely and is prevented from running the red light or missing the green light, and accidents are avoided.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a system for identifying traffic lights during vehicle running. Background technique [0002] Automobiles are defined as follows: non-track-borne vehicles driven by power with 4 or more wheels, mainly used for: carrying people and or goods; traction vehicles carrying people or goods; special purposes. In 1879, German engineer Karl Benz successfully tested a two-stroke experimental engine for the first time. In October 1883, he founded the "Benz Company and Rhine Gas Engine Factory". In 1885, he made the first Benz patented motor vehicle in Mannheim. 0.9 horsepower single-stroke gasoline engine, this car has some basic features of modern cars, such as spark ignition, water cooling cycle, steel pipe frame, leaf spring suspension, rear wheel drive, front wheel steering and brake handle, etc. On January 29, 1886, German engineer Karl Benz applied for a patent for his motor vehicle. In N...
