Abstract: The present disclosure describes projecting a structured light pattern projected onto a surface and detecting and responding to interactions with the same. The techniques described here can, in some cases, facilitate recognizing that an object such as a user's hand is adjacent the plane of a projection surface and can distinguish the object from the projection surface itself. Movement of the object then can be interpreted, for example, as a specified type of gesture that can trigger a specified type of operation to occur.

Abstract: The present disclosure describes projecting a structured light pattern onto a surface and detecting and responding to interactions with the same. A method includes-acquiring an image based on light reflected from a vicinity of the projection surface, and identifying regions of the acquired image that correspond to a feature that is within a specified distance of the projection surface by identifying regions of the acquired image for which intensity data differs relative to other regions of the acquired image and which fit a specified homographic relationship with respect to corresponding regions of a reference image.

Abstract: Presenting a merged, fused three-dimensional point cloud includes acquiring multiple sets of images of a scene from different vantage points, each set of images including respective stereo matched images and a color image. For each respective set of images, a disparity map based on the plurality of stereo images is obtained, data from the color image is fused onto the disparity map so as to generate a fused disparity map, and a three-dimensional fused point cloud is created from the fused disparity map. The respective three-dimensional fused point clouds is merged together so as to obtain a merged, fused three-dimensional point cloud. The techniques can be advantageous even under the constraints of sparseness and low-depth resolution, and are suitable, in some cases, for real-time or near real-time applications in which computing time needs to be reduced.
