Abstract
An example method to control a light source in structured light imaging associated with a target includes obtaining two-dimensional image information and depth information of an image including the target and a scene, associating the depth information with pixels of the image, selecting a first set of pixels of the pixels based on a first set of the depth information and a second set of pixels of the pixels based on a second set of the depth information, calculating a first average pixel luminance (APL) of the first set of pixels and a total APL of the first and the second sets of pixels, obtaining a weighted APL based on the first APL and the total APL and controlling the light source based on the weighted APL.
