Double-side vision intelligent detection device for vehicle passenger monitoring

Abstract

The invention discloses a double-side vision intelligent detection device for vehicle passenger monitoring. The double-side vision intelligent detection device for vehicle passenger monitoring comprises two sets of image acquisition units installed on the two sides of a road, each set of image acquisition unit comprises an infrared light source, an infrared camera and a visible light camera, the infrared light sources irradiate infrared light into a vehicle through vehicle window glass, the infrared camera is aligned with the interior of a vehicle for shooting to obtain an infrared image of passengers in the vehicle, the visible light camera collects a visible light image and transmits the visible light image to an image workstation through a network switch, and after the visible light image is processed by a vehicle identification processing unit, a detection result is output to a terminal display unit. According to the invention, an accurate and reliable passenger counting result inthe vehicle and associated information such as the license plate number, the vehicle model and the like of the taken vehicle can be provided, and a more convenient and faster tracking and positioningfunction is realized.

Description

technical field [0001] The invention relates to the fields of machine vision and intelligent transportation, in particular to a method of collecting multi-angle images of vehicles through multiple cameras, and realizing the recognition function of the number of passengers, license plate numbers and vehicle models based on artificial intelligence algorithms. Background technique [0002] With the continuous development of the level of urbanization, the requirements for intelligent traffic on urban roads continue to increase. Machine vision detection technology is not only used to identify information such as license plate numbers and vehicle models, but also to monitor the number and even details of passengers inside the vehicle. feature. This technology has a wide range of application values ​​in intelligent transportation, public safety, military and other fields, especially in improving the efficiency of road traffic and checking violations of laws and regulations in vehic...

Problems solved by technology

The disadvantage of this method is that it is impossible to observe the situation of the rear passengers

Second, the relevant information of the vehicle cannot be provided

Their disadvantages are that there are occlusions, and they can only observe local areas in the car. Second, infrared light or single-wavelength imaging cannot provide relevant information about the vehicle.
