Infrared thermal images reflect object temperature information that is less affected by environmental conditions.They have strong application value for nighttime security monitoring,driving assistance,shipping,military investigation,and other aspects,under certain conditions.In recent years,artificial intelligence has been used in the development of target detection and recognition technology in imaging and various fields.This paper proposes a nighttime target detection method combining infrared thermal imaging image processing and artificial intelligence target detection.Thermal imaging videos are acquired in real time for pre-processing in order to enhance the contrast and details of the thermal images,and the latest target detection framework,YOLOv3,based on deep learning is utilized to detect specific targets in the acquired thermal images and subsequently output the detection results.The test results show that the proposed method has high recognition rate and desirable real-time performance at nighttime;it combines the advantages of infrared thermal imaging nighttime monitoring and artificial intelligence target detection.Furthermore,it has been demonstrated that tracking technology has great application in nighttime target recognition.
