The detection device comprises a base frame, a thermal image lens unit, a visible light lens unit, a processing unit and a screen unit.The thermal image lens unit is suitable for taking a thermal image toward at least one object to be measured.The visible light lens unit is suitable for taking a visible light image towards the at least one object to be measured.The processing unit receives the thermal image and performs image identification. When it is determined that the temperature of at least one object to be measured in the thermal image exceeds a predetermined temperature, the visible image corresponding to the thermal image is marked, and the marked visible image is output.The screen unit signal is connected with the processing unit to display the marked visible image.Thus, the identification time of the detector can be reduced and the identification trouble can be reduced, and the convenience of use can be greatly improved.一種檢測裝置，包含一基架、一熱影像鏡頭單元、一可見光鏡頭單元、一處理單元，及一螢幕單元。該熱影像鏡頭單元適用於朝至少一待測物拍攝一熱影像。該可見光鏡頭單元適用於朝該至少一待測物拍攝一可見光影像。該處理單元接收該熱影像並進行影像辨識，於判斷該熱影像中之該至少一待測物之溫度超過一預定溫度時，標記該熱影像所對應之可見光影像，並輸出所標記之該可見光影像。該螢幕單元信號連接該處理單元，用以顯示所標記之該可見光影像。藉此，可減少檢測人員辨識的時間並降低辨識困擾，大幅提高使用便利性。
