AI Technical Summary

Technical Problem

Existing systems struggle to accurately determine the degree of congestion in vehicles, particularly when passengers are standing, which is crucial for managing passenger density and preventing the spread of infectious diseases like COVID-19.

Method used

A method and system that utilize cameras to capture images of vehicle interiors, detect individuals, generate rectangular detection areas around them, and determine congestion based on overlapping detection areas within specific target areas, excluding seated passengers and focusing on standing passengers near entry and exit points.

Benefits of technology

Accurately determines vehicle congestion levels, reducing the risk of overcrowding and infection spread by providing precise passenger density and total count data, facilitating real-time congestion management and operational adjustments.

Abstract

A method for determining the degree of accumulation or congestion in a vehicle includes: an image acquisition stage that captures the interior 101 of a passenger vehicle; a detection stage that identifies individuals P3, P4, and P5 in the image and generates, for each detected individual, rectangular detection areas DA3, DA4, and DA5 surrounding them; and a stage that determines the degree of congestion in the vehicle based on a target area Tg and the detection areas DA3, DA4, and DA5 in the image. The target area is an area within the image where a passenger standing on an island 103 in the vehicle is captured. In the determination stage, the degree of congestion in the vehicle is determined based on the number of detection areas that overlap with the target area.
