Problems solved by technology

However, when there are few vehicles in front, the drivers of the vehicles tend to neglect their own driving speeds, resulting in speeding.
Although with the advancement of science and technology, many roads have been installed with vehicle speed monitoring devices, but judging from their effects, they are basically punitive technical means and measures, warning drivers to obey traffic regulations through punitive means, now Some road speed measurement and monitoring technologies cannot send warning information to vehicle drivers in real time, obviously there is a congenital technical deficiency that lacks humanization

Abstract

The invention discloses a velocity-limiting mark recognizing and vehicle-velocity control method and system based on a vehicle traveling recording instrument. The method includes the steps that the vehicle traveling recording instrument collects an image through a camera in real time and carries out intensification and de-noising processing on the image; the processed image is compared with a pre-stored database template with a road velocity-limiting mark to judge whether the velocity-limiting mark exists in the image or not, and if the velocity-limiting mark exists in the image, the velocity-limiting mark is recognized to obtain the velocity-limiting velocity; the current vehicle velocity is adjusted according to the obtained velocity-limiting velocity. According to the velocity-limiting mark recognizing and vehicle-velocity control method and system, the vehicle-traveling velocity-limiting mark exists in a current road section is automatically recognized through the vehicle traveling recording instrument of a vehicle, a control command is output according to the recognition result, and the vehicle velocity is automatically controlled; meanwhile, a driver learns the velocity-limiting information of a road in real time, the driving safety of the driver is improved, and unnecessary traffic accidents are reduced.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a speed limit sign recognition and vehicle speed control method and system based on a driving video camera. Background technique [0002] With the increasing development of the automobile industry, automobiles have become the main means of transportation for people to travel. As the number of automobiles increases year by year, the construction of road infrastructure and the improvement of people's driving habits are relatively lagging behind. Casualties and property losses caused by traffic accidents are increasing year by year. Increase. [0003] For the safety of roads and vehicles, urban roads and high-grade highways, especially expressways, must set vehicle speed limit signs on each road section, so as to remind vehicle drivers to control their speed and drive carefully, so as to avoid illegal or even accidents due to speeding. cause a traffic accident. However, when t...
