Problems solved by technology
The thermal imager searches and marks the area with the highest temperature in the current infrared image, and sets this area as the monitoring area. When the temperature in this area is detected to rise, it indicates that the target object in this area is abnormal. For areas outside the monitoring area and It cannot play the role of monitoring, so it is impossible to detect abnormalities in other areas in the infrared image in time

The present application discloses a method, device, device and system for anomaly monitoring based on dual-light fusion infrared images, including: acquiring visible light images and infrared images whose image display contents are consistent and collected synchronously; inputting the visible light images into a pre-trained neural network The network outputs the transformed infrared image; obtains the grayscale difference between the transformed infrared image and the same area in the infrared image; determines whether the grayscale difference is greater than a preset threshold; if so, determines that the area corresponding to the grayscale difference is abnormal. After the conversion, the infrared image is converted from the visible light image. The gray value of each area has nothing to do with the temperature. When the temperature of a certain area is abnormal, the gray value in the infrared image will change, and the gray value of the same area in the two images will be obtained. The grayscale difference value determines whether there is an abnormality based on the relationship between the grayscale difference value and the preset threshold, and realizes abnormality detection for all areas, not limited to the area with the highest temperature, and can more effectively detect abnormality areas.
Description
technical field [0001] The present application relates to the technical field of image detection, and in particular, to an abnormality monitoring method, device, device and system based on dual-light fusion infrared images. Background technique [0002] Infrared imaging technology is based on the difference of infrared radiation of objects. Since different objects or different parts of the same object usually have different thermal radiation characteristics, such as temperature difference, emissivity, etc., after thermal infrared imaging, the objects in the infrared image are due to It is distinguished by the difference of its thermal radiation. [0003] At present, when monitoring the target object in the infrared image according to the infrared image, the monitoring is mainly performed by monitoring the preset monitoring area (the area with the highest temperature in the infrared image). The thermal imager searches and marks the area with the highest temperature in the cu...
