Vision Guided Radar System for Enhanced Vital Signs Detection

Vital signs, such as heart and respiratory rate, provide critical insight into a person’s health. Radar has been used to remotely analyze and detect human activity and vital signs for many years. Despite all the great features such as motion sensitivity, privacy preservation, penetrability, and more, radar has limited spatial degrees of freedom compared to optical sensors, which makes it a challenge to sense individual vital signs in crowded environments without prior information.

 

Researchers at Arizona State University have developed a multiple input multiple output (MIMO) radar system combined with a sensitive 3-D depth camera to detect the vital signs of multiple people simultaneously, including in crowded, complex environments. The dual-sensor system can automatically estimate torso landmarks from single or multiple subjects. Once mapped, chest movement related to cardiac and respiratory function can be detected and monitored. This system has been successfully tested in various multiple-subject scenarios.

 

This dual-sensing system improves existing physiological monitoring systems in realistic environments for use in telemedicine, smart homes, in-cabin monitoring, security surveillance systems and more.
