摘要 提出了一种新颖的单目俯视客流图像的快速行人检测方法。该方法是针对俯视行人头部或头肩部特征进行的检测的。根据行人头部在俯视图中的左、右两半对称,左、中、右结构,上、下两部分基本相同等空间分布特征,利用积分图计算、比较目标区域内矩形子块的灰度累加值来实现这类特征的检测;此外,融合头部区域颜色均匀的特征,计算并判别否是行人。实验证明,该检测方法是快速和有效的。 A novel and rapid method for monocular pedestrian detection with a vertical-view camera was proposed. Based on the symmetry or asymmetry of head (or head and shoulder) in the space distribution, which could be calculated by integral images, pedestrian heads could be estimated quickly in a verticalview image, combined with regional characteristics of uniform color in a head. The experiment shows a promising result.
