Non-contact Robust Respiration Detection By Using Radar-Depth Camera Sensor Fusion
2020
In this paper, a non-contact respiration detection scheme based on Doppler radar-depth camera sensor fusion has been proposed. A continuous-wave (CW) Doppler radar sensor and a depth camera are used to measure the respiratory motion separately. Then the Bayesian sensor fusion algorithm is used to estimate the cycle-to-cycle breathing rate. The experiments prove that the proposed fusion scheme can provide an accurate breathing rate estimation than using a single sensor. In particular, the proposed scheme can give a reasonable estimation even under the influence of body movement.
