Vehicle-mounted roadblock recognition system and method based on laser imaging technique

Abstract

The invention discloses a vehicle-mounted roadblock recognition system and method based on a laser imaging technique. The vehicle-mounted roadblock recognition method is characterized in that a laser photographing device is arranged on an automobile to collect roadway images, a multi-media digital signal processing (DSP) processing chip is arranged at the back end for analytical processing, object features are extracted through pattern recognition, voice prompt is performed according to the recognition result, and the recognition result can also be displayed on a display screen. The vehicle-mounted roadblock recognition system and method have the advantages that images far away for more than 1km can be collected by aid of infrared laser photographing and can be collected at night or in severe weather, road ahead conditions which cannot be seen by human eyes of automobile drivers can be seen through infrared laser photographing, the images can be analyzed by aid of a method combining the pattern recognition and a support vector machine, the result is transmitted to the drivers, so that the drivers can make judgment in advance, accidents are avoided, casualty accidents are reduced to the minimum, and life safety and property safety of the country and people are guaranteed.

Description

technical field [0001] The invention relates to a vehicle-mounted roadblock recognition system and method based on laser imaging technology, and belongs to the technical field of pattern recognition and image processing. Background technique [0002] As the speed of automobiles becomes faster and faster, the number of automobiles increases, and traffic accidents become more frequent. According to statistics, in the whole year of 2001, 78,000 people died in traffic accidents, exceeding 60% of the total number of deaths in various safety accidents in that year. In 2003, nearly 100,000 people died in traffic accidents, causing direct economic losses of 3.3 billion yuan. The analysis of road traffic accidents shows that more than 80% of the accidents are caused by the driver's lack of reaction, more than 65% of the vehicle collisions belong to rear-end collisions, and the rest belong to side collisions. Mercedes-Benz's research on various traffic accidents shows that most traf...

Problems solved by technology

my country started relatively late in this area, but has made some progress under the impetus of the national "Seventh Five-Year Plan", "Eighth Five-Year Plan" and "863" plans, and has made in-depth research on intelligent mobile robot technology, computer vision, and computer video processing technology. The research has achieved remarkable results, but there is still a certain distance from the practical level, and there is also a certain gap with European and American countries
