Optimize-at-Capture: Highly-adaptive Exposure Controlling for In-Vehicle Non-contact Heart-rate Monitoring
Researchers have developed a new adaptive exposure control system for in-vehicle non-contact heart-rate monitoring. This system proactively adjusts camera exposure settings based on predictive modeling of skin reflections, aiming to maintain optimal brightness for accurate heart-rate signal extraction. The proposed method, demonstrated on the ExpDrive dataset, significantly outperforms fixed exposure and standard auto-exposure techniques, reducing mean absolute error by 6.31 bpm and increasing success rate by 32.3 percentage points in challenging driving conditions.
