Abstract

PURPOSE: A digital image processing system for radiograph images is provided to achieve improved efficiency of transport, storage and search by allowing the result of photographing to be stored in a single compact disk. CONSTITUTION: A CMOS(20) is arranged underneath a test object(10), and a radioactive ray(30) is applied in the direction opposite to the CMOS. Thus, photosensitive data is stored in a CMOS sensor, and transmitted to a computer(50) in a real time basis through an interface card(40) connected to the CMOS sensor. Thus-transmitted data is stored into a hard disk of the computer so as to allow for a rapid search for the data.

Description

방사선 투과 영상의 디지털 정보화 시스템{Digital Information System of Radiographic Testing Image}Digital Information System of Radiographic Testing Image

본 발명은 금속의 용접부내에 결함이 있는지 비파괴검사하는 분야에서 주로 사용하는 방사선 투과시험의 결과물 처리 방법이다. 용접부 한 쪽에 필름을 대고, 다른 쪽에서 방사선을 조사하면, 방사선이 투과한 양에 따라 필름이 흑화된다. 두꺼운 부분은 방사선이 덜 투과하여 허옇게 되고, 얇은 부분은 방사선의 투과량이 많아서 검게 흑화된다. 만일 용접부 내부에 기공 등이 있다면 방사선이 용접금속에 덜 흡수되므로 필름에는 검은 점으로 나타난다. 이런 방법을 이용하여 기자재 용접부 내부에 결함이 있는지 비파괴검사할 수 있다. 이에 대한 상세한 방법은 한국산업규격(강 용접부의 방사선 투과시험방법 및 투과사진의 등급분류방법: KS B 0845)에 상세히 기술되어 있다.The present invention is a resultant treatment method of a radiographic test mainly used in the field of nondestructive inspection for defects in welded metal parts. When the film is placed on one side of the weld and the radiation is irradiated on the other side, the film is blackened in accordance with the amount of radiation transmitted. The thicker part is thinned due to less radiation, and the thinner part is blackened due to the large amount of radiation. If there are pores, etc. inside the weld, the radiation will be absorbed less by the weld metal, resulting in black spots on the film. This method can be used for nondestructive testing of defects in the welds of equipment. Detailed methods for this are described in detail in Korean Industrial Standards (Radiation Test Methods for Steel Welds and Classification of Transmission Pictures: KS B 0845).

본 발명의 관심 내용은 위에 기술한 투과사진의 처리 문제이다. 방사선투과 필름의 크기는 여러가지가 있다(예:3⅓×12, 3⅓×17, 4×12, 4×17, 7×17, 10×12, 14×17인치 등) 이러한 크기의 필름을 촬영하여 용접부의 품질을 평가한 다음, 분류하고 보관해왔다. 수 만장의 필름을 창고에 보관하는 경우에 다음과 같은 문제점이 있었다. 필름을 보관할 창고가 점점 부족해졌고, 창고에서 필름을 찾아오는 시간이 오래 걸렸으며, 필름의 훼손 및 분실 사고가 잦았다.A concern of the present invention is the problem of processing of the above-mentioned transmissive photographs. There are various sizes of radiographic film (e.g. 3⅓ × 12, 3⅓ × 17, 4 × 12, 4 X17, 7 x 17, 10 x 12, 14 x 17 inches, etc.) Films of this size have been photographed to evaluate the quality of the welds, and then sorted and stored. There were the following problems when storing tens of thousands of films in a warehouse. There was a shortage of warehouses to store films, the time it took to retrieve films from warehouses, and frequent film damage and loss.

이를 개선하고자 필름을 컴퓨터에 저장하여 보관 및 검색 하고자 시도를 하였다. 이에 대한 기존의 기술을 활용하고자 하였다. 병원에서 환자의 가슴 등을 찍은 엑스선 투과사진은 최근에 개발된 엑스선 감지 촬상소자의 어레이(array)로 대체되고 있다. 즉 필름이 있을 자리에 촬상소자를 배치하여 곧바로 컴퓨터에 입력하는 방식이다.To improve this, we attempted to store and retrieve the film on a computer. We tried to use the existing technology for this. X-ray transmission images of a patient's chest in a hospital are being replaced by an array of recently developed X-ray sensing imaging devices. In other words, the image pickup device is placed where the film is to be directly input to the computer.

기존의 촬상 소자는 씨씨디카메라(CCD)로 연결되는 데 화질이 나빠 현장에서 사용이 불가능하다. 그 다음에 나온 것이 씨모스(CMOS)센서 어레이 판을 이용한 경우이다. 이는 카셋트 타임으로 되어 있어 쵤용 후 이를 리더기에 꼽아 데이터를 읽어내는 방식이다. 이는 카셋트를 넣었다 빼었다 하는 불편함이 있기 때문에 여기에 인터페이스 카드를 꼽아 곧 바로 컴퓨터가 읽을 수 있도록 한 것이 본 발명의 특징이다.Conventional imaging devices are connected to CD-cameras (CCDs), which are not suitable for use in the field due to poor image quality. Next came the case with CMOS sensor array plates. This is the cassette time, so after plugging it into the reader and reading the data. This is because it is inconvenient to insert and remove the cassette, it is a feature of the present invention that the interface card is plugged in so that the computer can immediately read.

도 1 : 영상처리 장치1: Image Processing Apparatus

이하 본 발명의 구성 및 작용에 대하여 기술하고자 한다. 도 1 은 본 발명의 개념도를 그린 것이다. 시험 대상물(10)의 한 쪽에 씨모스(20)를 놓고 반대 면에서 방사선(30)을 쏘면 감광 데이터가 씨모스 센서에 저장되고, 이 데이터는 씨모스 센서판에 연결된 인터페이스 카드(40)를 통하여 실시간으로 컴퓨터(50)로 전송되는 것이다. 이렇게 전송된 데이터는 컴퓨터 하드 디스크에 저장되어 추후 신속한 검색이 가능해진다.Hereinafter will be described the configuration and operation of the present invention. 1 is a conceptual diagram of the present invention. When the CMOS 20 is placed on one side of the test object 10 and the radiation 30 is shot from the opposite side, the photosensitive data is stored in the CMOS sensor, and the data is transmitted through an interface card 40 connected to the CMOS sensor plate. It is transmitted to the computer 50 in real time. The transferred data is stored on the computer hard disk for quick retrieval later.

본 발명의 고안의 효과로는 현재 각 회사의 창고에서 제대로 분류되지 못하여 검색이 사실상 불가능한 실태가 개선되어 단 시간에 관심 구역의 검사결과를 검색하여 조치할 수 있게된다. 또한 촬영되는 검사결과물을 보고서와 수십 박스의 필름으로 납품하는 대신, 보고서 및 필름을 한 장의 컴팩트 디스크에 저장하여 납품할 수 있으므로, 운송, 보관 및 검색의 효율성을 높일 수 있다.The effect of the invention of the present invention can not be properly classified in the current warehouse of each company can not actually search is improved to be able to search and measure the inspection results of the area of interest in a short time. Rather than delivering reports and dozens of boxes of filmed inspection results, reports and films can be stored on a single compact disc for greater efficiency in transportation, storage and retrieval.
