Monitoring the vital signs of an aircraft passenger or crew members could be beneficial for various reasons. However, providing contact based sensors during flight is not the preferred method to achieve this goal. With the ubiquity of low-cost digital cameras and advanced image processing algorithms, an image-based remote monitoring of vital signs is feasible. This work explores the usability of a non-contact image photoplethysmography (iPPG) inside an aircraft cabin to measure the heart rate of passengers. Using a consumer camera, iPPG signals were estimated based on the analysis of color intensity changes in specific regions of the face. The developed system was evaluated with respect to its robustness against subject motion and the typical vibrations occurring in an aircraft. The results showed that using a consumer camera, a reliable estimation of the heart rate was possible under certain constraints. It was also shown that the vibrations of an aircraft did not affect the accuracy of the estimated heart rate.
