A Research on Traffic Calculation Using Stereo Video Camera

Evaluation of pedestrians flow by time transition of traffic line density distribution

“…Pedestrians flow outdoors is affected by their congestion density, the formation of road and square, field conditions, the arrangement of structures (buildings, houses, railway stations and so on), the position of entrances and exits of them and the public facilities (stairs, monuments, bus stops, crossing points, fountain and so on) [1][2][3][4][5][6][7][8]. The direction, velocity and density change dynamically with time transition.…”

Measur ement and Identification of Moving Object Flow Using Digital Video Camer a

“…In other words, the moving region is overlapped, and the lap probability of the moving region in the present of frame and the moving region in the previous frame is calculated [6] .…”

“…Therefore, we designed an algorithm that determines the number of moving regions from the tracking result of several frames for which the separation/integration process was repeated [6] .…”

“…However, this method has a disadvantage that this method has extremely high labor costs and is associated with human measurement errors due long working hours using manual counting methods [1] . Therefore, researches on automatically measuring traffic flow based on video-recorded images are actively underway [2]- [6] .…”

“…As such, there is demand for an alternative measurement method that can accurately measure human traffic flow even at times of congestion and without restricting the camera position. To this end, we previously developed a measurement system that accurately determines traffic flow when the flow is congested by the high overlapping of pedestrians [6] . However, a limitation of our method is that all moving objects are processed as pedestrians, making it impossible to count correctly the number of passing pedestrians in the situation where there are additionally moving objects such as luggage.…”
