상기 목적을 달성하기 위하여 본 발명에 의하면, 차량용 영상처리장치에 있어서, 렌즈와 렌즈의 초점위치에 슬릿이 형성된 에지 필터를 장착하여, 수직성분에 대한 에지만이 영상으로 남아 CCD 카메라로 받아들여 이미지 프로세싱에 이용되도록 이루어지는 것을 특징으로 하는 수직 슬릿 필터를 이용한 에지 검출장치가 제공된다.In order to achieve the above object, according to the present invention, in the vehicle image processing apparatus, by mounting an edge filter with a slit formed in the lens and the focal position of the lens, only the edge of the vertical component is left as an image to take into the CCD camera image An edge detection apparatus using a vertical slit filter is provided, which is adapted to be used for processing.

따라서, 차량용 영상처리장치에 수직 슬릿을 이용하게 함으로써 영상처리에 필요한 시간 및 비용을 줄일 수 있게 된다.Therefore, by using the vertical slit in the vehicle image processing apparatus it is possible to reduce the time and cost required for image processing.

이하에서는 양호한 실시예를 도시한 첨부 도면과 관련하여 본 고안의 수직 슬릿 필터를 이용한 에지 검출장치를 상세하게 설명한다.Hereinafter, an edge detection apparatus using a vertical slit filter of the present invention will be described in detail with reference to the accompanying drawings showing a preferred embodiment.

본 고안의 도면 전체를 통하여 동일한 부분에는 동일한 도면부호를 사용하기로 한다.The same reference numerals will be used for the same parts throughout the drawings of the present invention.

도 2와 도 3 도시와 같이, 차량용 영상처리장치에 있어서, 렌즈(10)와 렌즈(20)의 초점위치에 슬릿(31)이 형성된 에지 필터(30)를 장착하여, 수직성분에 대한 에지만이 영상으로 남아 CCD 카메라(40)로 받아들여 이미지 프로세싱(50)에 이용되도록 구성된다.2 and 3, in the vehicular image processing apparatus, the edge filter 30 having the slit 31 is formed at the focal position of the lens 10 and the lens 20, so that only the edge of the vertical component The image is configured to remain in the image and be received by the CCD camera 40 for use in the image processing 50.

상기와 같이 구성된 수직 슬릿 필터를 이용한 에지 검출장치의 작동을 이하에서 설명한다.The operation of the edge detection device using the vertical slit filter configured as described above will be described below.

차량용 영상처리장치들은 주관심의 대상이 차선이 되게 됨으로 영상에서 수직선만을 찾아내게 된다.Vehicle image processing apparatuses find only vertical lines in an image because the subject of interest becomes a lane.

이것을 디지탈 처리가 아닌 영상처리기를 사용하여 영상의 수직 에지만을 추출하려 하는 것이다.This is to extract only the vertical edge of the image using an image processor, not digital processing.

렌즈(10)를 통과한 영상은 그 렌즈(10)의 초점에서 퓨리에 변환이 이루어진다.An image passing through the lens 10 is Fourier transformed at the focus of the lens 10.

상대적으로 주파수가 높은 성분(선)은 촛점에서 가운데로 몰리고 낮은 성분(면)은 바깥쪽으로 위치하게 된다.Higher frequency components (lines) are centered at the focal point and lower components (faces) are located outward.

따라서, 렌즈(10)와 렌즈(20)의 초점위치에 수직 슬릿(31)이 형성된 에지 필터(30)을 장착하면 수직성분에 대한 선(에지)만이 영상으로 남게되어 이를 CCD 카메라(40)로 받아들여 이후의 이미지 프로세싱(50)에 이용하게 함으로써 영상처리에 필요한 시간 및 비용을 줄일 수 있게 된다.Therefore, when the edge filter 30 in which the vertical slits 31 are formed at the focal positions of the lens 10 and the lens 20 is mounted, only lines (edges) for the vertical components remain as images, which are transferred to the CCD camera 40. It is possible to reduce the time and cost required for image processing by accepting and using it for later image processing 50.

본 발명은 상기한 바와 같은 구성에 따라, 차량용 영상처리장치에 수직 슬릿을 이용하게 함으로써, 영상처리에 필요한 시간 및 비용을 줄일 수 있는등 유용한 효과가 얻어진다.According to the configuration as described above, by using the vertical slit in the vehicle image processing apparatus, a useful effect such as to reduce the time and cost required for image processing can be obtained.

본 발명을 특정의 바람직한 실시예에 관련하여 도시하고 설명하였지만, 이하의 특허청구의 범위에 의해 마련되는 본 발명의 정신이나 분야를 이탈하지 않는 한도내에서 본 발명이 다양하게 개조 및 변화될 수 있다는 것을 당 업계에서 통상의 지식을 가진 자는 용이하게 알 수 있다.While the invention has been shown and described with reference to certain preferred embodiments, it will be understood that the invention can be variously modified and modified without departing from the spirit or scope of the invention as set forth in the following claims. Those skilled in the art can easily know that.
