Abstract
An imaging system includes multiple LED modules, a single image sensor, a controller, a processing unit and a depth map generator. Each LED module has a distinct angular emission profile and emits light having a distinct wavelength range. The image sensor detects light originating from at least two of the LED modules after reflection by an object in a field of view of the image sensor to provide an image sensor output. The controller controls the LED modules to turn on and off such that only one LED module emits light at a time. The processing unit processes the image sensor output to identify an intensity profile for the reflected light from each of the LED modules. The depth map generator determines an angular position of the object based at least on the intensity profile for the reflected light from each of the LED modules.
