Under ideal conditions, the root mean squared error is around 2.60 bpm, 2.22 cpm, 6.91 mm Hg, 4.88 mm Hg, and 0.86 ☌ for HR, RR, systolic BP, diastolic BP, and BST, respectively. So far, BP and SpO2 are monitored with RGB cameras only, whereas BST is derived from FIR cameras only. HR and RR can be measured using red, green, and blue (RGB) and near-infrared (NIR) as well as far-infrared (FIR) cameras. One hundred and four articles remained: 60, 20, 6, 2, and 1 of the articles focus on HR, RR, BP, BST, and SpO2, respectively, and 15 on multiple vital signs. In total, we retrieve 905 articles and screened them regarding title, abstract, and full text.
#LEPTON 3 FLIR SKIN#
We include five vital signs: heart rate (HR), respiratory rate (RR), blood pressure (BP), body skin temperature (BST), and oxygen saturation (SpO2). We consider articles that were published between January 2018 and April 2021 in the English language. However, some questions are unanswered: (i) Which vital sign is monitored using what type of camera? (ii) What is the performance and which factors affect it? (iii) Which health issues are addressed by camera-based techniques? Following the preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement, we conduct a systematic review of continuous camera-based vital sign monitoring using Scopus, PubMed, and the Association for Computing Machinery (ACM) databases.
In recent years, noncontact measurements of vital signs using cameras received a great amount of interest.
