Objects having a flat surface such as a table are detected by processing a depth image and a color image. A mask indicating an area likely to include an object having the flat surface is generated by processing a depth image including the depth information. A color image corresponding to the depth image is then cropped using the mask to detect a portion of the color image that likely include the object having the flat surface. Geometric features of the cropped color image such as lines are then detected to determine the location and orientation of the object having the flat surface. A subset of the detected geometric features is selected as outlines of the flat surface. |
