    Abstract: This disclosure relates to illumination modules operable to increase the area over which an illumination source, such as a vertical-cavity surface-emitting laser or light-emitting diode, illuminates. Such illumination modules include a substrate having electrical contacts, an illumination source electrically connected to the substrate, a collimation assembly operable to collimate the light generated from the illumination source, a translation assembly operable to translate light over an area, and a mask assembly. In various implementations the illumination source may be rather small in area, thereby reducing the cost of the illumination module. Some implementations of the illumination module can be used for the acquisition of three-dimensional data in some cases, while in other cases some implementations of the illumination module can be used for other applications requiring projected light.

    Abstract: First and second stereo images are acquired. The first image is partitioned into multiple segments, wherein each segment consists of image elements that share one or more characteristics in common. A segmentation map is generated in which each of the image elements is associated with a corresponding one of the segments to which it belongs. A respective disparity value is determined for each of the segments with respect to a corresponding portion of the second image, and the disparity value determined for each particular segment is assigned to at least one image element that belongs to that segment. A disparity map indicative of the assigned disparity values can then be generated. Generating the disparity map in this manner can, in some instance, help reduce edge and/or feature thickening.
