A Method And System For Flicker Testing Of Loads Controlled By Building Management Devices

Abstract: The invention relates to a method and system for automated flicker testing of a light emitting device. The disclosed method and system captures a plurality of images of the light emitting device using an image capturing device. The image capturing device captures images consecutively in a predefined time interval. The disclosed method and system identifies a region of interest (ROI) for the light emitting device in one image and corresponding region of interests (ROFs) in other images. Further, the identified ROIs are processed. The processing of the ROIs includes converting the grayscale values of the ROIs into corresponding luminance values. A dip in luminance value is determined between the corresponding ROIs in the consecutively captured images and a flicker is identified if the dip in luminance value is greater than a predefined value.
