Description

technical field

[0001] The invention belongs to the application of panoramic computer vision sensor technology, digital image processing technology, embedded system, urban road digital coding technology and network communication technology in road traffic state detection, especially a road traffic state detection device based on panoramic computer vision . Background technique

[0002] Today's traffic problems have become a global "urban problem", and traffic congestion is the main manifestation of the city's "traffic disease". The "cause" of urban traffic congestion stems from a variety of factors, and traffic congestion directly affects the quality of people's travel, especially those who use vehicles for transportation. Congested road vehicles, frequent traffic accidents, deteriorating traffic environment, energy shortage, and increasing environmental pollution. These increasingly serious traffic problems are related to the basic concepts of modern traffic, namely access...
