LCAS Thermal Physiological Monitoring Dataset


L-CAS Thermal Physiological Monitoring Dataset

Collected by the Optris PI-450 thermal imager


This dataset is recorded for evaluating thermal-based physiological monitoring algorithms that can measure respiration and heart beat rate. The dataset contains thermal images of different human faces acquired in the Lincoln Centre for Autonomous Systems (L-CAS) at the University of Lincoln, UK. Data were recorded into different rosbag files, each corresponding to a person. The thermal camera recorded each person for two minutes with a frequency of 27Hz. People were asked to keep static in the first one minute, then move their head up and down, forward and back, turning right and left, each action was held for 10 seconds.


This dataset provides:

  1. Robot Operating System (ROS) rosbags. Each rosbag contains about 3,000 continuous thermal images.
  2. Ground truth for respiration and heart beat


Recording platform

  The Optris PI-450 thermal imager was mounted at 1.3m from the floor, on the top of a Kompaï robot. The Kinect was mounted at 1.1m. The distance between the robot and the face was about 1.3m. Thermal images were recorded using the Optris official driver. Temperature data is encoded as:
float t = (float)(data - 1000) / 10.f.
