Measurement of Pedestrian Groups Using Subtraction Stereo
نویسندگان
چکیده
In this paper, detection of pedestrian groups and counting of the number of pedestrians in each group using “subtraction stereo” are discussed. Subtraction stereo is a stereo vision method that focuses on the movement of objects to make a stereo camera robust and produces range images for moving regions. Pedestrian groups are detected with a standard labeling, and three dimensional (3D) features of pedestrian groups are measured from range images obtained by subtraction stereo. Then a method to count the number of pedestrians in a group is proposed. The basic algorithm of the subtraction stereo is implemented on a commercially available stereo camera, and the effectiveness of the method to count the number of pedestrians is verified by experiments using the stereo camera.

Nighttime Foreground Pedestrian Detection Based on Three-Dimensional Voxel Surface Model
Pedestrian detection is among the most frequently-used preprocessing tasks in many surveillance application fields, from low-level people counting to high-level scene understanding. Even though many approaches perform well in the daytime with sufficient illumination, pedestrian detection at night is still a critical and challenging problem for video surveillance systems. To respond to this need...
متن کاملImprovement of Human Tracking in Stereoscopic Environment Using Subtraction Stereo with Shadow Detection
The combination of subtraction stereo with shadow detection we propose improves people tracking in stereoscopic environments. Subtraction stereo is a stereo matching method which is fast and robust for the correspondence problem – one of the most serious issues in computer vision – restricting the search range of matching to foreground regions. Shadow detection gives adequate foreground regions...
متن کاملA Multi-Pedestrian Detection and Counting System Using Fusion of Stereo Camera and Laser Scanner
Automated vehicle counting technology has been in use for many years, but developments in automated pedestrian counting technology have been limited. Pedestrians are more difficult to detect, track and count because their paths are much less constrained. In this paper, we present an advanced pedestrian counting system using a stereo camera and a laser scanner. A mapping algorithm has been devel...
متن کاملVideo-Based Monitoring of Pedestrian Movements at Signalized Intersections
Pedestrian and cyclist crossing characteristics are important for the design of urban intersections and signalized crossings. Parameters, such as waiting time, crossing time, and arrival rate are key variables for describing pedestrian characteristics and improving crossing design and signal timing plan. Manually collecting such data is often extremely labor intensive. Therefore, we introduce a...
متن کاملPedestrian Detection Algorithm in Nighttime Environment Using the Cascade HOG in Lab Space
In this paper, an algorithm to track night pedestrians in real time is proposed. First, data is converted into a night L * a * b * color space, and then the L area is extracted. This data combined with image subtraction creates preprocessing data. Then, using the Cascade Histogram of Oriented Gradient (HOG) algorithm detects the pedestrian at night.
