Abstract

A method and apparatus merge depth maps in a depth camera system. According to a possible embodiment, a first image of a scene can be received. The first image can include first image coordinates. A second image of the scene can be received. A third image of the scene can be received. An x-axis depth map of the first image coordinates can be generated based on the first and second images. A y-axis depth map of the first image coordinates can be generated based on the first and third images. The y-axis can be perpendicular to the x-axis. Edge detection can be performed on the first image to detect edges in the first image. A confidence score map can be generated for each depth map. A higher confidence score on the confidence score map of the x-axis depth map can be set for a pixel on an edge at an angle closer to the y-axis than the x-axis for the pixel on the x-axis depth map. A lower confidence score on the confidence score map of the y-axis depth map can be set for a corresponding pixel on the y-axis depth map. A depth value of a pixel on a fusion depth map can be selected based on the confidence score maps and the depth maps.
