The invention relates to the field of infrared monitoring, and particularly relates to an infrared thermal image monitoring system against fog days and a method. The system comprises a video acquisition unit, an upper computer unit, and a video processing unit. The method comprises steps: an infrared thermal image video of a fog environment is acquired via an infrared thermal imager, and the video is stored to the upper computer; the infrared thermal image video is decomposed into infrared images, defogging treatment is carried out on the infrared images, and the infrared images after defogging are combined into an infrared thermal image video; moving object recognition and tracking treatment are carried out on the infrared thermal image video, and the infrared thermal image video after treatment is displayed and stored in the upper computer. Through carrying out defogging treatment on the infrared thermal image video in the fog environment, definition of the infrared thermal image video can be effectively improved, accuracy of subsequent moving object recognition and tracking is improved, the problem of vague fog video monitoring can be effectively solved, an important role is played in video monitoring, traffic dispatching, ship steering and the like, and the system and the method can be widely popularized and applied.
Description
technical field [0001] The invention relates to the field of infrared monitoring, in particular to an infrared thermal image monitoring system and method for foggy days. Background technique [0002] In video surveillance, foggy weather is usually encountered, which will cause blurred video images. The existing countermeasures are generally to process the video images acquired by ordinary cameras with a defogging algorithm, or according to the characteristics of longer infrared wavelengths, which can overcome the influence of the foggy environment to a certain extent, and use infrared thermal images The instrument acquires infrared thermal image video images to achieve the effect of defogging. Chinese Patent Publication No. CN 103440731 A provides an infrared thermal imaging online monitoring system, Chinese Patent Publication No. CN 201286155 provides an infrared thermal imaging monitoring system, Chinese Patent Publication No. CN 201285596 provides a Infrared thermal ima...
