摘要:

基于视频的车辆检测与计数在交通基础设施管理中发挥着关键作用。传统的基于图像的计数方法通常包含两个主要步骤:初始检测和后续跟踪,这两个步骤应用于所有视频帧,导致计算复杂度显著增加。为解决这一问题,本工作提出了一种替代且更高效的车辆检测与计数方法。所提方法无需跟踪步骤,仅专注于检测关键视频帧中的车辆,从而提高了效率。为实现这一目标,我们开发了一个将用于车辆检测的 YOLO 与 Visual Rhythm(视觉节奏)相结合的系统;Visual Rhythm 是一种生成时空图像的方法,使我们能够关注包含有用信息的帧。此外,该方法可用于任何涉及需要检测和识别的单向运动目标的计数应用。使用真实视频进行的实验分析表明,所提方法在一组视频上实现了约 99.15% 的平均计数准确率,处理速度比基于跟踪的方法快三倍。

英文摘要:

Video-based vehicle detection and counting play a critical role in managing transport infrastructure. Traditional image-based counting methods usually involve two main steps: initial detection and subsequent tracking, which are applied to all video frames, leading to a significant increase in computational complexity. To address this issue, this work presents an alternative and more efficient method for vehicle detection and counting. The proposed approach eliminates the need for a tracking step and focuses solely on detecting vehicles in key video frames, thereby increasing its efficiency. To achieve this, we developed a system that combines YOLO, for vehicle detection, with Visual Rhythm, a way to create time-spatial images that allows us to focus on frames that contain useful information. Additionally, this method can be used for counting in any application involving unidirectional moving targets to be detected and identified. Experimental analysis using real videos shows that the proposed method achieves mean counting accuracy around 99.15% over a set of videos, with a processing speed three times faster than tracking based approaches.
