In-vehicle people counting system based on visible light polarization

Abstract

The invention discloses an in-vehicle people counting system based on visible light polarization. The counting system comprises a data acquisition and information processing subsystem, a main control and people counting subsystem and an illumination subsystem. The data acquisition and information processing subsystem comprises a polarization module and an information processing module, and is used for image acquisition and polarization information fusion vehicle-penetrating membrane processing; the illumination subsystem supplements light to the environment in the vehicle; and the main control and people counting subsystem is used for detecting passengers in the vehicle and counting people. The system is high in statistical accuracy of the number of people in the film-pasted vehicle, and is good in detection effect.

Description

technical field [0001] The invention belongs to the field of intelligent security technology, and relates to a system for counting the number of passengers in a film-attached vehicle. Background technique [0002] With the gradual development of the economy and the advancement of science and technology, people's living standards continue to improve. Cars have long been an important means of transportation for people to travel. With the development of the country, the centralized construction of some enterprise parks has also increased the difficulty of park access management. , Important checkpoints or areas need to check the situation of people entering the vehicle to ensure safety. Take the Shanghai Chemical Industry Park as an example. The park covers an area of ​​36.1 square kilometers, involving 153 enterprises, more than 50,000 people, and more than a dozen access roads. There are so many vehicles entering and leaving the park during rush hours that it is impossible to...

Problems solved by technology

[0004] At present, the main way to detect people in the car is to add sensors in the car for perception, but it is usually impossible to evaluate the correctness of external personnel to further confirm its correctness. External detection is affected by glass film and vehicle movement, and infrared, millimeter wave and ultrasonic waves are often used. Limited, ordinary visible light cameras are affected by filmed glass, strong light, and stray light, and the detection probability is not very ideal
