Embodiment Construction

[0029] Hereinafter, the present invention will be described more fully with reference to the accompanying drawings, in which embodiments of the invention are shown. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure is thorough and will fully convey the scope of the invention to those skilled in the art.

[0030] It will be understood that although the terms "first", "second", etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. Thus, a "first" element discussed below could also be termed a "second" element without departing from the teachings of the present invention.

[0031] It will be understood that when an element is referred to as being "coupled" or "connected" to another element, it can be directly ...

Abstract

A preprocessing apparatus in a stereo matching system is provided. In the preprocessing apparatus, coordinate information of a stereo camera is received, a new address of a pixel of an image is specified in real time, and left and right images are interpolated, using the new address of the pixel and weight information of the stereo camera.

Description

technical field [0001] The present invention relates to a technique for preprocessing a three-dimensional image, and more particularly to a preprocessing device in a stereo matching system used in a stereo camera or the like. Background technique [0002] As is well known, human vision is one of the senses for obtaining surrounding environment information, and the position and distance of an object can be recognized through binoculars. That is, visual information received through both eyes is combined into distance information so that a person can move freely without inconvenience. [0003] A stereo camera system is used when a mechanism is used to realize the structure of human vision. [0004] In a stereo camera system, stereo matching is performed on images obtained using two cameras. In this case, the external and internal structures of the two cameras are different from each other. Therefore, in order to equalize the internal structures of the two cameras, in a conve...
