Abstract
A method of detecting a flame in an image comprising the step of acquiring a series of infrared images from an infrared imager. Image flow vectors are calculated for each of the series of infrared images and stored in a corresponding 2D vector array. At least one 3D image flow data set is generated from the corresponding 2D vector arrays. A 2D pixel intensity array is generated for each of the series of infrared images. A 3D pixel intensity data set is generated from the 2D pixel intensity arrays. A Fourier Transform and infrared metrics are calculated. The infrared metrics are compared to an infrared threshold criteria. A corresponding 2D threshold array for each of the series of infrared images is generated. A 3D threshold data set is generated from the 2D threshold arrays. A flame status is determined based on the 3D threshold data set.
