Abstract
The disclosure relates to method and system for evaluating luminance in Augmented Reality (AR) applications. The method includes receiving a plurality of video frames corresponding to an AR object in a real-world environment at a current camera angle; for each of the plurality of video frames, subtracting the set of AR object pixels from the set of environment pixels in a frame; calculating mean luminance value corresponding to the set of AR object pixels in each of the at least one of the plurality of blocks in the frame and corresponding to each of the plurality of blocks of the grid in the real-world environment through a light sensor; comparing mean luminance value for each of the plurality of blocks of the grid with mean luminance value corresponding to the set of AR object pixels; and evaluating luminance of AR object at the current location in the AR application.
