Digital signage is widely utilized in digital-out-of-home (DOOH) advertising for marketing and business. Recently, the combination of the digital camera and digital signage enables the advertiser to gather the audience demographic for audience measurement. Audience measurement is useful for the advertiser to understand the audience's behavior and improve their business strategies. When an audience is facing the digital display, the vision-based DOOH system will process the audience's face and broadcast a personalized advertisement. Most of the digital signage is available in an uncontrolled environment of public areas. Thus, it poses two main challenges for the vision-based DOOH system to track the audience's movement, which are multiple adjacent faces and occlusion by passer-by. In this paper, a new framework is proposed to combine the digital signage with a depth camera for tracking multi-face in the three-dimensional (3D) environment. The proposed framework extracts the audience's face centroid position () and depth information () and plots into the aerial map to simulate the audience's movement that is corresponding to the real-world environment. The advertiser can further measure the advertising effectiveness through the audience's behavior.
数字标牌在户外数字（DOOH）广告中被广泛用于营销和商业活动。最近，数码相机与数字标牌的结合使广告商能够收集受众人口统计信息以进行受众测量。受众测量有助于广告商了解受众行为并改进其商业策略。当受众面对数字显示屏时，基于视觉的DOOH系统会处理受众的面部并播放个性化广告。大多数数字标牌都处于公共场所的无控制环境中。因此，对于基于视觉的DOOH系统跟踪受众的移动来说，存在两个主要挑战，即多个相邻面部和路人遮挡。本文提出了一种新框架，将数字标牌与深度相机相结合，以在三维（3D）环境中跟踪多个人脸。所提出的框架提取受众面部质心位置（）和深度信息（），并绘制到航拍地图中以模拟与现实世界环境相对应的受众移动。广告商可以通过受众行为进一步衡量广告效果。
