Abstract

The invention discloses a barrier vehicle-mounted early warning device and method based on a light emitting diode (LED) lamp group. The device comprises a pedestrian barrier recognition module, a brightness sensor, a processing module, an LED lamp group module and a sound warning module, the pedestrian barrier recognition module is mounted on the upper portion of the middle of a vehicle windshield, the brightness sensor is mounted in front of an automobile, the processing module is mounted in the automobile, the LED lamp group module is located at the lower edge of the front windshield, the pedestrian barrier recognition module mounted in the middle of the vehicle front windshield and the brightness sensor mounted in front of the automobile serve as input to be connected with the processing module, the LED lamp group module and the sound early warning module receive output signals of the processing module to perform barrier sound-light early warning, the pedestrian barrier recognition module is used for detecting pedestrians and barriers, the pedestrians and the barriers are recognized by means of a target detection and tracking technology, horizontal coordinates of the barriers that are relative to the pedestrian barrier recognition module are locked, and the brightness sensor is used for collecting vehicle indoor brightness information.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a vehicle-mounted early warning device and method for obstacles based on LED lamp groups. Background technique [0002] Road traffic accidents occur frequently in our country, and traffic safety is a matter of people's livelihood that everyone pays close attention to. In 2012, a total of 4.727 million traffic accidents occurred across the country, resulting in a total of 59,000 deaths and hundreds of millions of direct property losses. The number is shocking. Relevant data show that a considerable part of the casualties caused by traffic accidents are caused by collisions between people and vehicles. The response ability is relatively poor, and the response speed is relatively lagging. Therefore, the development and application of the vehicle active safety early warning device and its method has positive practical significance. Studies related to intelligent...
