Abstract：To addressthe clinical need for continuous respiratory rate monitoring in dogs with heart failure，this study developed a novel non-contact respiratory monitoring system based on Hybrid TOF（optical time--flight） sensing. A hybrid single-point/array TOF sensing architecture was proposed，incorpo rating a spatial adaptive monitoring model to accommodate varying pet postures. An STM32-embedded platform enabled sensor synchronization raw signal preprocessng，while a LabVIEW-based host computer implemented real-time respiratory waveform analysis algorithms. Optical calibration tests optimized array TOF ranging parameters. Testing on small-sized dogs under static conditions demonstrates a respiratory rate measurement error ⩽2 breaths per minute （BPM）. The LabVIEW interface enables realtime visualization respiratory waveforms BPM values，confirming the feasibility optical TOF sensing for vital sign monitoring. The hybrid TOF system achieves high-precision static respiratory monitoring in dogs through optical measurement optimization spatial adaptive strategies，which provides a miniaturized，low-cost bionic optical solution for veterinary medical applications.
