| Popis: | 101 Light speckle distance measuring is a depth sensor composed of 3D structured light comprised of infrared rays camera and infrared rays projector. By coding the space and decoding via the chip, we can get the depth information of the space. It has been applied on the use of Kinect for Xbox 360 of Microsoft and Xtion of ASUS for man-machine interface. During studying of light speckle distance measuring, we find the technique is limited by some restrictions of infrared rays, such as special material, reflective surface and the same wavelength. Stereo vision is an important form of computer vision. It is based on disparity and utilizes imaging device to get two images in different position by calculating the deviation to get the 3D information. In this paper, we develop the cross-modal stereo vision using the RGB camera and infrared rays camera by Kinect. Via two independence depth systems, we can remedy defects of the equipments and correct the depth. This paper presents the cross-modal stereo vision in different kinds of cameras. Without using other sensors, we obtain the depth area which is missing from light speckle distance measuring and higher accuracy depth information by rectification of two systems and completely reconstruct the 3D scene. |
