Driving safety system and barrier screening method thereof
First Claim
1. A barrier screening method comprising:
- mounting a driving safety system in a vehicle, with the driving safety system including a computer, an image acquisition module and a distance detection module, with the computer connected to the image acquisition module and the distance detection module; and
the computer performing the method comprising;
receiving at least one piece of barrier information of at least one barrier from the distance detection module and at least one frame of image information from the image acquisition module with each frame of image information containing the at least one barrier;
performing a screen and analysis algorithm to process each one of the at least one piece of barrier information to screen out noise existing in the at least one piece of barrier information coming from any non-barrier and reflected from a surrounding environment;
generating location information of a corresponding barrier after screening out the noise from the at least one piece of barrier information;
comparing the location information of the corresponding barrier with the at least one frame of image information to eliminate the noise generated from objects on the ground and to obtain front target information;
detecting a current driving status of the vehicle by a vehicle status module; and
sending a brake activation signal to slow down the vehicle or a brake fluid cutoff signal to a brake control module according to a determined analysis based upon the at least one piece of barrier information of the at least one barrier.

Abstract
A driving safety system mounted in a vehicle includes an image acquisition module and a distance detection module connected to a vehicle-mounted computer and respectively acquiring at least one piece of barrier information and at least one frame of image information. The vehicle-mounted computer analyzes the barrier information and the image information, constantly receives barrier information in the course of driving, and performs a screen and analysis algorithm to screen out noise from the surrounding environment and a comparison analysis algorithm to eliminate noise reflected from objects on the ground, to accurately acquire front target information. Accordingly, the driving safety system can correctly determine barriers in the front when the vehicle is moving to achieve the goal of enhancing driving safety.
