在自然界中,凡是温度高于绝对温度零度的物体均向外辐射红外能量,温度越高,红外辐射越强。通过非接触探测,测定目标本身和背景之间的红外能量差,并将其转换为电信号,经过处理即可形成热辐射图象。同一目标的热辐射图象和可见光图像不同,它不是人眼所能看到的可见光图像,而是目标表面温度分布的图像。采用这一技术手段,便能实现对目标进行远距离热状态图像成像和测温,并可进行图像识别、行为分析等智能应用。本文简要谈一下红外热成像技术的发展、优缺点和产 In nature, any object whose temperature is above zero of absolute temperature radiates infrared energy outwardly. The higher the temperature, the stronger the infrared radiation. By non-contact detection, the infrared energy difference between the target itself and the background is measured and converted into an electrical signal which is processed to form a thermal radiation image. The same target thermal radiation image and visible light image is different, it is not the human eye can see the visible image, but the target surface temperature distribution of the image. Using this technology, we can realize long-distance thermal image imaging and temperature measurement of targets, as well as intelligent applications such as image recognition and behavior analysis. This article briefly talk about the development of infrared thermal imaging technology, advantages and disadvantages and production
