FAIL-SAFE DETECTION USING THERMAL IMAGING ANALYTICS

Various techniques are provided to process captured thermal images to determine whether the thermal images exhibit degradation associated with environmental effects and/or security conditions. In oneexample, a method includes capturing a plurality of thermal images of a scene. The thermal images are processed to generate first and second background images associated with first and second time periods to filter out changes in the scene occurring within the associated time periods. The first and second background images are edge filtered to generate first and second edge images. The first and second edge images are compared to determine a change in edges associated with the scene. A device is selectively operated in a fail- safe mode in response to the comparing. Additional methods and related systems are also provided. 提供了对所捕获的热图像进行处理以确定热图像是否表现出与环境影响和/或安全条件相关联的劣化的各种技术。在一个示例中，一种方法包括捕获场景的多个热图像。对热图像进行处理以生成与第一时间段和第二时间段相关联的第一背景图像和第二背景图像，以滤除在相关联时间段内发生的场景中的变化。对第一背景图像和第二背景图像进行边缘滤波以生成第一边缘图像和第二边缘图像。将第一边缘图像和第二边缘图像进行比较以确定
