Abstract: Disclosed are a system and a method extensible for performing, in real-time, stereo snatching for calculating depth images with a result of searching for points of similarity by using images taken with two cameras. The system includes a coordinate creating module, a census transform module, a delay XOR calculation module, a stereo matching module, and a control module. Accordingly, by using the system extensible for performing stereo matching, depth information of corrected images can be acquired in real-time without using computer systems or software programs for special purposes. Furthermore, since the system extensible for performing stereo matching can be simply realized by hardware, the system and the method of the present invention can be easily applied to actual intellectual-type robots, industrial settings, etc.

Abstract: Disclosed is a system and a method for rectifying stereo images, which are acquired by two cameras, in real-time by using a calibration matrix resulting from camera calibration. The system includes a coordinate generation module; a rectification coordinate generation module; a bilinear interpolation value generation module; a rectification coordinate memory; a bilinear interpolation memory; an image buffer; an rectification module; and a control module. A structure of a hardware system capable of real-time stereo rectification is provided, and the operation results have been verified by implementing a hardware device. The real-time stereo rectification system makes it possible to acquire rectified images in real-time without using a separate computer system or a software program.

Abstract: A laminography system includes a table, an X-ray source, an image intensifier, a view selector and a camera. The view selector has a prism for refracting a ray of light, and an adjusting part for adjusting the prism to a position in which images at a certain area of an image projecting plane of the image intensifier are received into the camera. The adjusting part has a first motor for rotating the prism along the circumferential direction of the image intensifier, and a second motor for rotating the prism in a direction perpendicular with respect to a radial direction of the image intensifier. Accordingly, the images at any areas of the image projecting plane of the image intensifier can be obtained. In addition, since an optical axis of the image passing through the prism and then received into the camera is in perpendicular relation with the camera, no image distortions occur.
