We collected a large dataset consisting of nearly 900 unique participants. For every participant we recorded two 30 second uncompressed videos, synchronized PPG waveforms and a single blood pressure measurement. Gender, age and skin color were also registered for every participant. The dataset includes roughly equal numbers of males and females, as well as participants of all ages. While the skin color distribution could have been more balanced, the dataset contains individuals from every skin color. The data was collected in a diverse set of locations to ensure a wide variety of backgrounds and lighting conditions. In an effort to assist in the research and development of remote vital sign measurement we are now opening up access to this dataset.

翻译：我们收集了一个包含近900名独特参与者的大型数据集。针对每位参与者，我们记录了2段30秒的无压缩视频、同步PPG波形以及单次血压测量值。同时记录了每位参与者的性别、年龄和肤色。该数据集的男女比例大致相等，并包含各年龄段的参与者。尽管肤色分布可以更加均衡，但数据集涵盖了所有肤色类型的个体。数据采集地点多样化，以确保背景和光照条件的广泛性。为促进远程生命体征测量的研究与发展，我们现开放此数据集的访问权限。
