종래의 실물 화상기에 관한 기술은 대한민국 특허청 등록특허공보 제0294909호, 제1012706호 등에 개시된 바 있다.Conventional real imager technology has been disclosed in the Republic of Korea Patent Publication No. 0294909, 1012706.
최근에는 3차원으로 대상물체를 전방위로 촬영하고, 대상물체의 실제 치수와 형태를 완벽하게 측정하여 이를 3차원 프린터기로 재현해 낼 수 있는 3차원촬영장치가 개발되어 있다.Recently, a three-dimensional photographing apparatus capable of photographing an object in three dimensions from all directions and fully measuring the actual size and shape of the object and reproducing it with a three-dimensional printer has been developed.
그러나, 종래의 실물 화상기는 다음과 같은 문제점이 있었다. However, the conventional real imager has the following problems.
(1) 대상물체의 상면을 2차원으로 촬영하기 때문에 사용자가 대상물체를 화상기를 회전시키거나 대상물체를 옮기면서 설명하여야 한다. (1) Since the upper surface of the object is photographed in two dimensions, the user should explain the object by rotating the imager or moving the object.
(2) 대상물체를 촬영하더라도 이를 데이터로 활용하는데에는 한계가 있어서 영상장치로 송출하는 것에 만족해야 한다. (2) Even if the object is photographed, there is a limit in using it as data, so it must be satisfied to send it to the imaging device.
(3) 3차원촬영장치는 대상물체를 정확히 측정하면서 데이터로 저장할 수 있으나 깊이나 크기를 측정하기 위해서 별도의 장치가 필요하여 가격이 고가이고 데이터의 양이 많아서 사용하기가 어렵다.(3) The three-dimensional photographing apparatus can be stored as data while accurately measuring the object, but it is difficult to use because the price is expensive and the amount of data is large because a separate device is needed to measure the depth or size.
본 발명은 상기한 문제점들을 해결하고, 학교나 기업 등에서 발표용으로 사용하거나, 대상물체를 3차원 데이터로 쉽게 전환할 수 있도록 하기 위해서 개발된 것으로, The present invention was developed in order to solve the above problems, to be used for presentation in schools, companies, etc., or to easily convert the object into three-dimensional data,
영상송출 및 영상처리장치가 내부에 형성된 베이스와;A base having an image transmission and image processing apparatus formed therein;

상기 촬영부의 지지대의 가운데 부분의 양측으로 돌출되는 원판지지대가 형성되고, 상기 원판지지대에 일측이 고정되어 모터에 의해서 회전가능하도록 형성되는 투명한 재질의 원판으로 형성되는 대상물체지지부로 구성되는 것을 특징으로 한다.A disc support projecting to both sides of the center portion of the support of the photographing unit is formed, characterized in that consisting of the object support portion formed of a disc of a transparent material which is fixed to one side to the disc support to be rotated by a motor do.
본 발명의 물체 전방위 촬영 3차원 실물화상기에 의하면 다음과 같은 효과가 발생한다.According to the object omni-directional photographing three-dimensional physical image of the present invention the following effects occur.
(1) 대상물체의 상면, 양측면, 후면 및 저면까지 전방위로 촬영이 이루어지기 때문에 한 번의 촬영으로 대상물체가 완전하게 3차원 데이터화되므로 사용자는 대상물체를 이동시키거나 별도의 조작을 하지 않아도 된다. (1) Since the shooting is performed in all directions to the top, both sides, the back, and the bottom of the object, the user does not need to move the object or perform a separate operation because the object is completely three-dimensional data in one shot.
(2) 대상물체의 외관만을 촬영하고 이를 이미지 적으로 완전하게 3차원 데이터로 만들 수 있으므로 3차원데이터로 활용할 수 있다.(2) It can be used as three-dimensional data because only the appearance of the object can be photographed and made into three-dimensional data completely.
(3) 대상물체의 치수를 정확하게 측정하지 않고, 대상물체의 외관의 촬영만으로 눈으로 확인할 수 있는 3차원데이터를 얻을 수 있으므로 비교적 저렴한 가격으로 운용이 가능하다.(3) It is possible to operate at a relatively low cost because 3D data that can be visually checked can be obtained only by photographing the appearance of the object without accurately measuring the dimensions of the object.
(4) 대상물체의 무게를 측정할 수 있도록 함으로써 별도의 장비없이도 무게데이터를 얻어 부피 및 밀도의 측정시 보조데이터로 활용할 수 있다.(4) By allowing the weight of the object to be measured, weight data can be obtained without additional equipment and used as ancillary data when measuring volume and density.

이하, 본 발명의 바람직한 실시예로 형성된 물체 전방위 촬영 3차원 실물화상기의 작동 및 영상촬영방법 등을 설명하면 다음과 같다.Hereinafter, an operation and an image capturing method of an object omnidirectional photographing 3D physical imager formed according to a preferred embodiment of the present invention will be described.
본 발명의 물체 전방위 촬영 3차원 실물화상기를 사용하여 대상물체(50)를 촬영하기 위해서는 전체를 덮을 수 있는 도 7과 같이 보호막(60)을 형성하는 것이 적당한데, 조명(230)의 효과를 최대한으로 높이기 위해서 사용한다.In order to photograph the object 50 using the object omni-directional photographing three-dimensional physical imager of the present invention, it is appropriate to form a protective film 60 as shown in FIG. 7, which covers the whole, and maximizes the effect of the illumination 230. Use to increase
상기 대상물체(50)를 원판(310)의 가운데에 위치하고 촬영을 준비한다. 이때, 대상물체(50)의 정가운데 축이 제1카메라(221)와 제2카메라(222)를 연결하는 축에 위치하도록 올려놓는 것이 중요하다. The object 50 is positioned in the center of the disc 310 to prepare for photographing. At this time, it is important that the center of the object 50 is placed so that the axis is located on the axis connecting the first camera 221 and the second camera 222.
그러나, 정확하게 위치하지 않더라도 제1카메라(221)와 제2카메라(220)에 촬영되는 영상의 보정을 통해서 위치보정이 이루어진다. However, even if the position is not correct, the position correction is performed by correcting the images photographed by the first camera 221 and the second camera 220.
상기와 같이 대상물체(50)를 위치한 상태에서 첫번째 촬영을 하면 대상물체(50)의 일면이 상부에서 측면 및 하부까지 촬영된다(a면촬영). When the first image is taken while the object 50 is positioned as described above, one surface of the object 50 is photographed from the upper side to the lower side and the lower side (a side photographing).
이후, 원판(310)이 회전하여 정해진 각도로 회전하면 대상물체(50)의 연속된 다른면이 촬영부(200)에 위치하게 되고 이때 두번째 촬영을 한다(b면촬영). Thereafter, when the disc 310 is rotated and rotated at a predetermined angle, another continuous surface of the object 50 is positioned in the photographing unit 200, and at this time, a second photographing is performed (b surface photographing).
상기와 같은 과정을 연속적으로 수행하여 각 면을 연결하여 대상물체(50)에 대한 3차원 데이터를 구성한다.The above process is continuously performed to form three-dimensional data about the object 50 by connecting the respective surfaces.
이때, 촬영된 면의 영상에서 음영의 채도를 측정하여 일부깊이를 측정하여 적용한다.At this time, the saturation of the shadow in the image of the photographed surface is measured to apply a partial depth.
촬영된 각 경도상의 면을 연결하여 대상물체(50)에 대한 3차원 데이터를 획득하고 이를 그림파일로 저장할 수 있음은 물론 고해상도 카메라(30)를 사용하여 축소, 확대가 가능할 수 있도록 제공된다.It is possible to obtain three-dimensional data on the object 50 by connecting the photographed hardness images and to store it as a picture file, as well as to reduce and enlarge the image using the high resolution camera 30.
상기 카메라(220)가 슬라이딩패널(240)에 의해서 형성되면, 최초 제1카메라(221)와 제2카메라(222)를 대상물체(50)에 수직하게 놓은 상태에서 원판(310)을 회전시켜 촬영하고 데이터를 획득한 상태에서, 슬라이딩패널(240)을 지지대(210)의 내주연을 따라 일정각도로 이동시켜 다시 원판(310)을 회전시켜서 촬영하면, 각 카메라(220)가 대상물체(50)의 다른 위도상의 면을 촬영하게 되므로 보다 정밀한 촬영이 가능해 진다. When the camera 220 is formed by the sliding panel 240, the first and second cameras 221 and 222 are placed perpendicular to the target object 50 to rotate the disc 310 to be photographed. In the state of acquiring the data, when the sliding panel 240 is moved at a predetermined angle along the inner circumference of the support 210 to rotate the disc 310 again to photograph, each camera 220 is a target object 50. The camera will shoot different latitude planes of the camera, allowing for more precise shooting.
또한, 카메라(220)의 설치개수를 줄일 수 있으면서도 촬영을 정밀하게 하기 위해서는, 슬라이딩패널(240)의 이동을 활용하여 여러 번 촬영하는 방법으로 해결할 수 있다.In addition, in order to reduce the number of installation of the camera 220 while precisely shooting, it can be solved by a method of taking several times by utilizing the movement of the sliding panel 240.
본 발명의 물체 전방위 촬영 3차원 실물화상기에 의하면 대상물체의 상면, 양측면, 후면 및 저면까지 전방위로 촬영이 이루어지기 때문에 한 번의 촬영으로 대상물체가 완전하게 3차원 데이터화되므로 사용자는 대상물체를 이동시키거나 별도의 조작을 하지 않아도 되고, 대상물체의 외관만을 촬영하고 이를 이미지 적으로 완전하게 3차원 데이터로 만들 수 있으므로 3차원데이터로 활용할 수 있으며, 대상물체의 치수를 정확하게 측정하지 않고, 대상물체의 외관의 촬영만으로 눈으로 확인할 수 있는 3차원데이터와 무게데이터를 얻을 수 있으므로 비교적 저렴한 가격으로 운용이 가능한 등의 효과가 발생한다.According to the object omni-directional photographing three-dimensional physical imager of the present invention, since the photographing is performed omnidirectionally to the top, both sides, the rear side and the bottom of the object, the object is completely three-dimensional data in one shot so that the user can move the object. It can be used as 3D data because it can photograph only the appearance of the object and make it completely 3D data in an image, and it can be used as 3D data, without accurately measuring the dimensions of the object. It is possible to obtain three-dimensional data and weight data that can be visually checked only by photographing the exterior, so that the operation can be performed at a relatively low price.
본 발명은 바람직한 실시예를 중심으로 기술되었지만, 당업자라면 이러한 기재로부터 후술하는 특허청구범위에 의해 포괄되는 본 발명의 범주를 벗어남이 없이 다양한 변형이 가능하다는 것은 명백하다.Although the present invention has been described with reference to the preferred embodiments, it will be apparent to those skilled in the art that various modifications may be made without departing from the scope of the present invention, which is covered by the following claims.
