Description

Sector lens for panorama shooting and its placement method {A DEVICE AND A ARRANGEMENT METHOD OF SECTOR LENS FOR PANORAMA IMAGE}

The present invention relates to a method for arranging a plurality of sector lenses for capturing a limited area of a certain angle so that panorama shooting can be performed. In particular, a method for arranging a sector lens for allowing panoramic shooting, which is a 360-degree full-orientation shooting, is possible.

Hereinafter, a configuration according to the related art according to an embodiment will be described in detail with reference to the accompanying drawings.

Referring to the basic principle of the sector lens, as shown in Fig. 1, in the frame 1 having a regular rectangular cuboid shape, a small hole is formed in the center portion of one side surface so as to be the entrance diameter 4. A film 2 is formed on the side opposite to the entrance diameter.

When the entrance diameter 4 of the frame coincides with the direction in which the subject or the object 10 is to be photographed, the reverse phase of the object is formed or formed on the film 2.

The sector lens will be described in detail with reference to FIG. 2, which coincides with the extension lines of the incidence angles 5 and 6 formed by the incidence aperture 2, and has a planar upper and lower first boundary surface 8 and left and right second boundary surfaces. By constructing each of the elements (9), the shape of the square horn-shaped sector lens is formed, and the rectangular objective lens 7 is attached at an appropriate position of the square horn-shaped end portion, and at the same time, the incident aperture 4 and the objective lens are provided. By arranging a large number of convex and concave lenses on a straight line where (7) coincides, the image pickup device can be imaged.

The image formed by the sector lens is converted into an electrical signal by the imaging device and output.

According to one embodiment of the prior art, since the sector lens I 32 has an angle of incidence of 36 degrees each vertically or horizontally, the sector lens I 32 is divided into 10 regions divided by 36 degrees of horizontal 360 degrees.

In the first step, the photographing area of the sector lens I 32 divided into 10 as described above is divided into 10 areas from 'A' to 'J' as shown in FIGS. 3 and 4, and the divided area. Ten sector lenses I 32 which are the numbers of are prepared.

3 is a second step, in which the sector lens I (32) is arranged in the regions B, D, F, H, and J as shown in FIG. 4, among the ten regions from the divided 'A' to 'J'. ), And the incidence apertures 4 are arranged to coincide on the same horizontal plane, thereby forming or forming the sector lens group of the first row 11.

4 is a third step, in which the sector lens I 32 is placed in the areas A, C, E, G, and I where the sector lenses are not arranged by the second step of the divided ten areas. On a horizontal plane arranged on the same plane, the incident diameter 4 coincides with one point, and parallel to the plane of the first column 11, while the incident diameter 4 coincides in the same straight line. Thereby forming or forming a group of sector lenses in the second row 12.

FIG. 5 is a cross-sectional state in which the sector lenses I 32 of the first row 11 and the second row 12 are arranged in the above steps, and the sector lens group of the first row 11 is shown. On the vertical incident angle alignment line to be formed, the lower side of the sector lens group of the second row 12 is not overlapped, or on the vertical angle alignment line formed by the sector lens group of the second row 12. In the drawing, a state in which the image side portion of the sector lens group of the first row 11 is arranged or arranged so as not to overlap or overlap is shown.

The plurality of sector lenses I 32 disposed according to the exemplary embodiment of the related art as described above have a full azimuth region of 360 degrees on a horizontal plane by the sector lens groups of the first row 11 and the second row 12. Can be photographed or recognized, and an area of 36 degrees can be photographed or recognized on a vertical plane.

The three-dimensional configuration of the sector lens I 32 of the first row 11 and the second row 12 arranged as described above is shown in three dimensions in FIG. 6.

Thus, the panoramic image system composed of only the sector lens I (32) FIG. 7 can be photographed mechanically without motion, and there is no resolution reduction in intensive surveillance, and a more innovative panoramic image system that can be expressed in real time video. As described above, since the sector lens groups of the first row 11 and the second row 12 are disposed so as not to overlap each other, there is a problem in that an unavoidable up and down deviation 13 occurs during the combining process. Of course, when photographing a long-distance subject, a negligible deviation or a sense of deviation 13 may be sensed when photographing a close distance.

An object of the present invention is to provide a plurality of lenses and CCD sensors while simultaneously photographing a 360 degree viewable panoramic image in real time in a no-moving state without using a pan / tilt, which must be mechanically precise. 17) can be used to increase the resolution of the intensive surveillance and provide a sector lens for panorama shooting that can be taken without distortion by directly photographing an image of a subject, and a method of arranging the same. It is to provide a revolutionary image by eliminating the upper and lower deviation 13 and at the same time by combining the sector lens properly.

In order to achieve the above object, the present invention provides a sector lens II (16) composed of a plurality of concave and convex lenses. 14), the lens is cut into a square with a reference line. Unlike the sector lens I 32, the incident aperture 4, or focus, does not exist in front of the lens, but exists inside the lens or behind the CCD sensor 17. In addition, the image incident line 14 or the optical path 15 is refracted inward from the inside of the lens so that it is not blocked on the rectangular lens cut by the extension line of the image incident line 14 and is projected onto the surface of the CCD sensor 17 as it is.

In addition, the combination of the sector lens I (32) and the sector lens II (16) allows the 360-degree panoramic image and the upper and lower images to be taken simultaneously without the vertical deviation 13 as follows.

In order to achieve the above object, the sector lens II 16 is arranged 360 degrees in the basic column, and the sector lens II 16 is further arranged below or above the reference column in order to further view the lower part or the upper part. . In this case, the sector lens should be installed one space apart (because the top or bottom part is reduced by a certain ratio). ) To shoot.

In other words, in order to see the bottom of the reference column, the sector lens I 32 is installed above the reference column to photograph the blanks.

Hereinafter, with reference to the accompanying drawings will be described a sector lens II (16) for panorama shooting according to the present invention and its arrangement method.

As described in FIG. 8, the lens is vertically extended by an extension line of the image incident line 14 which passes through the outermost lens and passes through the outermost lens so as to exactly match the sensing face plate 23 of the CCD Sersor 17. A lens cut out on the left and right basis is referred to as a sector lens 16.

When the image of the subject reaches the initial lens 24-1 through the image incident line 14, the optical path 15 of the lens is slightly refracted inward, so that the initial lens 24-1 and the sector lens II 16 are separated. There is a space for the external enclosure to bind.

When the optical path 15 of the lens reaches the sensing face plate 23 of the CCD sensor 17 via the second and third lenses, the image myth of the subject is detected by the CCD sensor PIN 18, the CCD sensor connector 19, and the CCD. When the multi-panel camera body 21 is reached via the sensor cable 20, the image is processed in the same manner as the images input from the other CCD sensors 17 and sequentially, through the multi-panel camera image output connector 22. 28).

In the sector lens II (16) of the present invention, a plurality of lenses can be combined up and down or left and right to form a three-dimensional extension screen, wherein the coupling means has a fastening groove 25 and a projection piece 26 as shown in FIG. It consists of. The general appearance of the sector lens II (16) has a quadrangular pyramid shape as shown in Fig. 9, and its shape is determined differently according to the angle of the lens.

In FIG. 10, a plurality of sector lenses II (16) for photographing the subject 10 as a panorama image in a vertical or horizontal plane are combined into a plurality of A, B, and C. In FIG.

In the visible range of the sector lens II (16) ABC, the image of the entire subject can be seen as one image by matching the respective image incident lines 14, and the frame switching transmission of each image is performed by the multi-plate camera at high speed. Combined images can be animated.

11 shows an embodiment in which three 120-degree sector lens II (16) are combined with three, 90-degree, 72-degree, 60-degree, and 45-degree sector lens (II) 32 to simultaneously realize a 360-degree left and right image.

In addition, when combining a plurality of sector lenses 16 to simultaneously implement a 360-degree left and right image, there is a camera fixing bracket 31 that can fix and support the device, and the center of the CCD sensor cable 20 can pass through. The CCD cable through hole 30 is drilled and the CCD cable 20 is connected to the multi-camera body 21 through the CCD cable through hole 30. Therefore, the multi-panel camera body 21 is located under the camera fixing bracket 31.

In addition, the combination of the sector lens I (32) and the sector lens II (16) is a method that can take a 360-degree panoramic image and the upper or lower image at the same time without the vertical deviation 13 as follows. Fig. 13 further arranges and installs the sector lens II (16) below horizontal (lower row) in order to view an image below horizontal (reference row). At this time, the width of left and right becomes narrow as it goes down horizontally, so it cannot be arranged in the same way as the sector lens II (16) in horizontal state. On the opposite side, the sector lens I 32 should be placed above the reference column (upper row) to see the bottom 34. The visible range 33 of the sector lens II 16 is and The visible range 34 is as shown in FIG.

As an example, in order to observe the bottom portion of the horizontal state (reference column) in the horizontal state lens II 16, the horizontal state portion is photographed with the sector lens II 16 as shown in FIG. In the row), sector lenses II (16) are provided one by one, and when the number of sector lenses (II) 16 in the reference row is evenly divided by two, the sectors installed at the bottom (lower row) below the horizontal level The sector lens I 32 is provided on the horizontal upper side on the vertical line different from the lens II 16, and in the case of an odd number, the sector lens I 32 is provided on the horizontal upper side on the same vertical line.

FIG. 15 shows a monitor image (a) before image processing when a 360 degree panoramic image is implemented using a 45 degree sector lens as an embodiment. That is, the image 39 observed in the sector lens I 32 installed in the upper column among the images below one level below the horizontal portion has a black portion as it goes down. This portion is only a portion covered by the sector lens II 16 provided below, and is not a blind spot of the image. This is solved by image processing in which both sides of the black portion are stretched at the same ratio in order to realize a more refined image on the monitor, which appears as image (b) after image processing.

As described above, in the case of constructing a 360-degree panoramic image by combining the Sector Lens II (16) and the Sector Lens I (32), a small number of lenses can be used. In case of construction, several lenses are required.

In other words, if the video frame rate may be slow because there is little change in the image, and instead, the long distance image needs to be enlarged, a 360 degree panorama may be constructed by combining several small sector lenses I and II (32, 16). In general, when there are many changes in the image and do not need to see a long distance, it is better to combine a large number of sector lenses I and II (32, 16) with a large number.

As described above, the vertical and vertical deviations (13) of the image in real time on the subject in the 360 degree azimuth region without using a mechanical driver as the sector lens for the panorama photographing and the arrangement method according to the configuration of the present invention. ) Can be used to shoot or recognize video panoramas without

In addition, by enlarging a specific portion of a subject photographed by a conventional digital processing technique of an image signal to a high resolution, there is an industrial or industrial use effect that can be accurately focused or monitored.

In addition, since it does not use expensive mechanical drives and corresponding controls, it is inexpensive, inexpensive to maintain, and even for inexperienced operators, it is easy to take panorama images or recognize 360-degree subjects easily. There is.
