The present invention discloses a telehealth care system using thermal imaging and a method thereof. The telehealth care system using thermal imaging includes an infrared thermal imager, an image process module and an analysis module. The infrared thermal imager captures a thermal image from an upper body of a patient. The image process module receives the thermal image and then generates a rolling-average temperature of area according to the thermal image. The analysis module is connected to the process module and determines the patient’s state according to the rolling-average temperature of area, a temperature of hypothermia, a temperature of fever and a temperature of hot spot.本發明係揭露一種熱成像式遠端照護系統及其方法。熱成像式遠端照護系統包含紅外線熱像儀、影像處理模組及分析模組。紅外線熱像儀擷取患者之上半身之熱影像。影像處理模組接收熱影像,並依據熱影像產生區域滾動平均溫度。分析模組連結影像處理模組,且依據區域滾動平均溫度、失溫溫度、發燒溫度及高溫點溫度判斷患者之狀態。100‧‧‧熱成像式遠端照護系統101‧‧‧潛在發燒警報102‧‧‧失溫警報103‧‧‧高溫警報104‧‧‧證實發燒警報110‧‧‧紅外線熱像儀111‧‧‧熱影像120‧‧‧影像處理模組121‧‧‧區域滾動平均溫度130‧‧‧分析模組300‧‧‧遠端照護站
