Description

One-shot panorama virtual reality photographing device}

The present invention relates to a one-shot panoramic VR recording apparatus, and more specifically, to a vertical and horizontal 360-degree direction by one shot in a state in which the one-shot panoramic VR recording apparatus is mounted on a support that is portable and height-adjustable, such as a camera monopod. High-quality full-screen panorama VR with bearing information can be taken easily and quickly even in high altitude.

In general, VR (Virtual Reality) means that all senses (visual, auditory, olfactory, taste, and tactile) of the human body are in a three-dimensional virtual environment similar to the real environment created through computer graphic (CG) technology. It is a technology that ultimately aims to maximize the utilization of information by interacting and immersing the virtually created world in three dimensions, and immersing human beings in this virtual space.

The current virtual reality technology is applied to various fields such as Web 3D, simulation, game, design, education, medical, military, etc. Among these virtual reality technologies, panorama VR (Panorama VR) is used to take images taken with a camera. This is a photo-based VR technology created by pasting. This manufacturing method rotates the landscape or the interior (360 ° horizontal or vertical) and connects the captured images through a processing process, attaching them and covering them with a spherical or cylindrical shape. The image is rotated, zoomed in / zoom out, and moved around a nodal point.

This panorama VR technology is introduced faster than other VR technologies in that it is easy to work, very inexpensive, and obtains results in a short time, and is currently used in ruins, tourism, architecture, model house, interior, travel, shopping mall, real estate, etc. It is used in various fields.

On the other hand, if you want to shoot the above-mentioned conventional panoramic VR, a tripod is installed on the floor, and the horizontal system is fixed on the tripod, and then the VR device which rotates the digital camera 360 degrees around the nodal point which is the shooting point on the horizontal system (= VR rotator or panorama head), and then finally mount the digital camera to the VR rotator, adjust the level so that the digital camera is completely horizontal, set the mode of the digital camera to the fully manual mode, After measuring exposure to the site, set the appropriate aperture value, shutter speed, and ISO settings.

Then, at least 4 to 50 shots are taken while rotating the VR rotator 360 degrees. At this time, if you want to create a 360-degree panoramic VR instead of 360 degrees horizontally, shoot up to the ceiling, and then rotate 360-degree vertically. To create a panoramic VR, the digital camera is removed from the VR rotator and the tripod is removed.

However, when shooting such a conventional panorama VR, first, the time to mount the tripod, level, VR rotator, digital camera, accurate leveling time using the level, time to measure the exposure to the field, digital camera Shooting takes a long time, such as shooting while rotating 360 degrees, removing the digital camera from the VR rotator, and shooting the floor directly by hand. Second, objects that move rapidly around the camera are ghosted in the final panoramic VR image. do. That is, for example, when a large object such as a bus passes by when shooting a VR, it is difficult to include all of them in a single image.

Third, while the existing panorama VR represented a static space without moving objects on the site like the introduction of the facility, it is now possible to put the scene of festivals, events, events, etc. into the panorama VR for the virtual experience on the Internet. In the conventional method, such as a lot of spatial and time constraints, it is difficult to capture the moment of the scene.

Fourth, because panoramic VR does not include bearing information, it is difficult to accurately determine the location of the site.Fifth, because the general tripod is used, the height of the nodal point, which is the camera's shooting point, cannot be raised above a certain height. There are many problems such as impossible to photograph, that is, when there is a barrier higher than human eye level such as a wall at the shooting site, it is impossible to photograph when the landscape beyond the wall is desired.

Meanwhile, various panoramic VR devices have been released in the market to solve the above problems, but most of them are for horizontal 360-degree panoramic VR without ceiling and floor, not vertically and horizontally 360-degree directions. Due to the structure, the resolution and the image quality of the full screen panoramic VR having a high quality on the Internet has been a problem.

Therefore, the present invention has been made to solve the above-mentioned conventional problems, the present invention is by one shot in a state in which the one-shot panoramic VR recording apparatus is mounted on a support that is portable and height adjustable, such as a camera monopod High-quality full-screen panoramic VR that includes orientation information in up, down, left, and right 360 degrees directions can be taken easily and quickly even at high altitudes, making it possible to produce spatial materials in a convenient form that overcomes time and space constraints. The purpose is to provide a one-shot panorama VR shooting device that can be enlarged.

Another object of the present invention is to provide a one-shot panorama VR recording apparatus that can not only reduce the time and cost required during panoramic VR shooting, but also can take a picture having a high resolution and high quality to maximize the shooting efficiency. There is.

In order to achieve the above object, the present invention provides a plurality of digital cameras seated and fixed on each camera mount for shooting panoramic VR on top of the VR head case, and detachably installed on the top of the VR head case.

As described above, the present invention includes azimuth information in up, down, left and right 360 degrees by one shot in a state where the one-shot panoramic VR photographing apparatus is mounted on a support that is portable and height-adjustable, such as a camera monopod. High-quality full-screen panoramic VR can be taken easily and quickly even at high altitudes, making it possible to produce spatial data in a convenient form that overcomes time and space constraints, and to expand the scope of application. It is a very useful invention that can not only shorten the time and cost of working, but also can take pictures with high resolution and high quality, thereby maximizing shooting efficiency, thereby greatly improving the efficiency and reliability of the device.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention for achieving the above object will be described in detail.

1 is an overall perspective view showing a one-shot panoramic VR photographing apparatus of the present invention, Figure 2 is an exploded perspective view of the VR head case and the case cover of the present invention, Figure 3 is a plan view of the case cover of the present invention is removed, Figure 4 is a plan view showing a VR head case with the case cover of the present invention is removed, Figure 5 is a bottom view of Figure 4, Figure 6 is an exploded view showing a digital camera mounted on the camera mount of the present invention 7 is a perspective view illustrating a combined state of FIG. 6.

The one-shot panoramic VR photographing apparatus of the present invention supports a stable state on the bottom surface of the support 10 to be photographed at the lower end of the rod-shaped support 10 that is elastically adjustable, such as a camera monopod or an antenna. Support member 20 having a disc shape for the removable is installed, in this case, as in the embodiment of the present invention to form a spiral groove on the lower outer peripheral surface of the support 10, the top center of the support member 20 The support member 10 may be detachably coupled to the support member 20 at the lower end of the support 10 by forming a fixing piece 22 having a spiral groove corresponding to the spiral groove at the bottom of the support 10. Another method may be detachably coupled, and the reason why the support member 20 is detachably coupled to the lower end of the support 10 is because of the panoramic VR shooting. This is because it is possible to photograph panorama VR in a state where the operator holds the support 10 by hand without using one support member 20.

In addition, the center of the VR head case 30 is detachably coupled to the upper end of the support 10, in which the spiral groove is formed on the outer peripheral surface of the upper end of the support 10 as in the embodiment of the present invention, In the center of the VR head case 30 to form a fastening hole 32 to be coupled to the spiral corresponding to the spiral groove of the top of the support (10) by detachably coupling the VR head case 30 to the top of the support (10) It may be combined, or can be detachably coupled in other ways.

In addition, each of the fixing holes 34 is formed at intervals of 90 degrees around the fastening holes 32 in the VR head case 30, and a measurement scale 36 is formed at one side of each of the fixing holes 34. ) Is formed, and the camera mount 50 to which the main body of the digital camera 40 is seated and fixed is installed on each of the fixing holes 34 located in the VR headcase 30, respectively, 40, the fish-eye lens 42 having an angle of view of 180 degrees up, down, left, and right is mounted on the camera mount 50, but is mounted so as to protrude outward when combined with the VR headcase 30. In this case, since each of the fisheye lens 42 is installed in a form protruding from the end of the digital camera 40, it is also possible to easily proceed to shoot the lower 90 degrees.
In addition, each of the camera mount 50 is formed such that when the digital camera 40 is mounted, the direction of the digital camera is directed at least 5 degrees upward, which includes the ceiling portion at the time of shooting, It is to mount the window and move continuously at high speed. When the present invention is mounted on the upper part of the body such as the sunroof of the vehicle, the entire background according to the moving direction of the vehicle can be taken more widely, and after shooting This is to increase the distortion rate and accuracy of the junction part according to the distortion correction and the moving speed in the image.

Each of the camera mounts 50 is a horizontal mount 52 for supporting the bottom surface of each digital camera 40, and is installed perpendicular to the horizontal mount 52, each digital camera 40 And a vertical mount 54 for wrapping and supporting one side of the rear end surface, and the VR head case for adjusting the mounting position of the camera mount 50 at the center of the horizontal mount 52. A position adjusting long hole 56 communicating with the fixed long hole 34 of 30 is formed so that the fastener 70 made of a butterfly bolt penetrates the fixed long hole 34 of the VR head case 30 to be horizontally mounted. As it is inserted into the position adjusting hole 56 of the base 52 and fastened by a nut, the mounting position of the camera mount 50 mounted on the VR head case 30 is fixed arbitrarily.

Further, the digital camera 40 is fixed to the vertical mount 54 of each camera mount 50 as the fastener 72 made of a fastening bolt is fastened to the digital camera 40 mounted therethrough. The fastening hole 58 is formed, and the inside of the horizontal and vertical mounts 52 and 54 of the camera mount 50 is mounted from the external shock in the state where the digital camera 40 is mounted. In order to protect 40, a plurality of shock absorbing members 60 made of a shock absorbing material such as rubber are attached.

In addition, one side of the support 10 is installed at the same time the camera release 80 is electrically connected to the digital camera 40 to shoot in one shot by operating four digital cameras 40 at the same time, the VR head case At the upper end of the VR head case 30 is detachably installed by a pair of coupling members 100 to which the case cover 90 for enclosing and protecting the interior of the VR head case 30 is detachably installed. A support groove having a cushioning member 62 attached therein to support the upper outer circumferential surface of 30 and the lower outer circumferential surface of the case cover 90 to surround the end of the fisheye lens 42 of each digital camera 40. (38) and (92) are formed in each recess, and a handle 94 for gripping is provided at the center of the upper end of the case cover 90.

In this case, a pad made of a material such as a rubber may be attached to remove a gap that may occur in the contact portion between the upper outer circumferential surface of the VR head case 30 and the lower outer circumferential surface of the case cover 90.

In addition, the horizontal pedestal 110 is installed horizontally on the upper portion of the support 10 to adjust the same as the orientation of the level 120 for leveling the digital camera 40 when shooting and the digital camera 40 when shooting. Compass 130 is configured to be installed side by side.

The difference from the conventional panoramic VR shooting when setting the digital camera before shooting with the one-shot panoramic VR shooting apparatus of the present invention configured as described above is as follows.

1. Set the shooting mode of the digital camera 40 to the aperture mode (A) rather than the fully manual (M) mode and take a picture.

-The reason for shooting in full manual mode in general panorama VR is that if the overlapping images have different exposures, the brightness changes suddenly at the overlapping part during blending process, which is very unnatural and unrealistic in the actual panoramic viewer program. Seems.

When taken in the aperture mode in the device of the present invention (the aperture value is set equal to all four digital cameras), each digital camera makes an appropriate exposure measurement for each digital camera.

In other words, because the images taken by each digital camera have different exposures, certain parts may look bright in some images, but the same parts may appear relatively dark in other images.However, different exposures can be solved through the general panorama image blending function. This is possible, and depending on the type of digital camera and the lens model, the number of images taken during general panorama VR shooting is over 10.

In general, two images taken in succession overlap with each other by about 30%. In the device of the present invention, four 180-degree fisheye lenses 42 may theoretically include all directions including up, down, left, and right 360 degrees. .

That is, all the objects in the field can be said to be photographed twice by the digital camera 40. Since the photographed objects in the aperture mode compared to each other, the exposure is different, but all the objects during panorama blending Because there is an overlap for, it is much more flexible for the natural exposure compensation of the final panoramic VR image than the blending of typical panoramic VR.

In addition, the digital camera 40 may be set to the aperture mode to naturally solve the low dynamic range problem of the digital camera, which is a typical problem when shooting a panoramic VR, and to allow a rapid burst shooting by the panoramic VR. do. For example, it is possible to mount the device of the present invention in a car and move at a high speed while taking a rapid exposure measurement according to each field exposure when shooting continuously.

2. Enhance ISO sensitivity enough to secure the shutter speed appropriately for the lighting conditions depending on the weather and time of day.

-In general, when you take a picture, the minimum ISO should be taken to get a clear picture without noise. In the conventional conventional panoramic VR method using a VR rotator, since the tripod fixes the digital camera, even if the shutter speed is slowed when the ISO is minimized, it does not matter, but in the present invention, the photographer generally uses the support 10 directly when shooting. The digital camera may shake during shooting because it is standing up and fixed by hand. To overcome this problem, it is possible to solve this problem by increasing the ISO speed to suit the lighting conditions of the scene.

3. Shoot with the image format set to RAW instead of JPEG.

In traditional panoramic VR shooting, it is common to shoot in RAW rather than JPEG to produce high-quality full-screen VR. In general, the reason for shooting in RAW rather than JPEG is that the width of the candidate lens (white balance, color correction) is much wider when shooting after candidate shooting.

In the conventional conventional panorama VR method, the shooting mode is taken in the fully manual mode, but in the device of the present invention, since the shooting mode is taken in the aperture mode, overlapping portions of the four images obtained after the shooting have different exposure values. At this time, the overlapping part of the image shows a difference in color and brightness. This problem can be solved through the panorama blending process as described in 1 above.

When the image blending process is performed, image color blending is performed by obtaining color information of overlapping portions of each image. The more information on color, the more natural (no sharp difference in color or brightness) is obtained. You can get it.

In other words, the more color information you have, the more advantageous it is to shoot in RAW rather than JPEG. While JPEG is an 8-bit compressed image format, RAW is the raw raw data of a CCD that is recognized by digital camera CCDs, so RAW files obtained after shooting must be processed to produce high-quality panoramic VR images. Can be obtained.

-RAW files are chromatic abberation and exposure correction (correction for too dark and too bright) in software and saved in 16-bit uncompressed TIFF format. The 16-bit TIFF image format, unlike JPEG, is a format that does not damage any image data.

Image noise reduction software, such as Noise Ninja, is used to remove noise caused by high ISO sensitivity in 16-bit TIFF, and then in 16-bit TIFF format.

After stitching and blending the panorama to a noise-free 16-bit TIFF image, you get a final panoramic VR image.

On the other hand, when using the one-shot panoramic VR recording apparatus of the present invention to plan a horizontal high-altitude panoramic VR containing the orientation information, first, to the four camera mount 50 fixed to the upper surface of the VR head case 30 After mounting the digital camera 40 equipped with the fisheye lens 42 having the angle of view 180 degrees up, down, left, and right, respectively, and after setting the digital camera 40 as described above, the VR head case 30 is supported. After fixing to the top of the (10), the support 10 is stretched to adjust the height to suit the desired height, at this time, when you want to shoot a high-altitude VR higher than the height of the support (10) Attach the extension to the support (10) and then upright (10) in the vertical state.

Then, if you want to include azimuth information when shooting by referring to the compass 130 installed on the horizontal pedestal 110 above the support 10, by rotating the support 10 so that a specific direction is applied to a specific digital camera direction After taking the photographing direction, finally leveling the horizontal state while checking the level 120 installed in parallel with the compass 130 on the horizontal pedestal 110, and installed on one side of the support 10, each digital camera ( By pressing the camera release (80) electrically connected to the 40) it is possible to operate the four digital cameras 40 at the same time to proceed with the shooting in one shot.

In addition, panoramic VR shooting with the orientation information in a state in which the photographer gripped by hand to shoot a desired point in a difficult situation in which the support 10 of the one-shot panoramic VR photographing apparatus of the present invention cannot stand or install a tripod. Attention should be paid to the fact that the one-shot panoramic VR photographing apparatus of the present invention weighs about 5 kg, so that the length of the support 10 must be adjusted within a range that the photographer can afford.

The photographing method is similar to the above-described horizontal photographing method except that the photographing is performed by directly holding the support 10. However, the photographing method undergoes the following process.

-After checking the orientation from the current point of the photographer to the point to be photographed, the support 10 is rotated so that a specific direction (for example, north) is applied to a specific digital camera direction (for example, the direction of the first camera). Catches.

-Be careful not to rotate the support 10 at the current point of the photographer and to tilt the support 10 in the direction of the point to be photographed, the point to note that if you tilt the support 10 more than 90 degrees bearing information Be careful not to go over 90 degrees because it will be reversed.

In addition, since the shaking may occur in the process of tilting the support 10, a slight error may occur in the azimuth angle. When photographing in this manner, the digital camera 40 is not horizontal at all. The horizontal level of Panorama VR is controlled programmatically. If a commercial program uses Panorama Tools, an open source library developed by Dr. Helmut Dersch, Germany, the horizontal VR image source that is not leveled at the time of shooting is displayed on the program. You can freely adjust the level simply by dragging the mouse.

Meanwhile, the method of producing 360-degree panoramic VR from the image source photographed by the one-shot panoramic VR photographing apparatus of the present invention does not deviate significantly from the conventional method of producing a conventional panoramic VR image. Be more careful than poetry.

-Since the color difference between exposure and exposure difference is different, to make the color correction as natural as possible, work with uncompressed 16-bit image except the final panoramic VR image.

-Stitching program that supports lens calibration to minimize the parallex error in software even when the nodal points are not matched with each other.

-Level Panorama Panorama using Panorama Tools.

In addition, the operation of producing a 360-degree, vertical, vertical, vertical panoramic VR image is performed as follows.

1. Perform the following corrections on the four RAW images you have taken using RAW professional correction software.

Chromatic Abberation

Exposure compensation (compensation for overexposure and underexposure)

-Vignetting correction

2. Save the corrected RAW image in uncompressed 16-bit TIFF format.

3. Use image noise specialist software on uncompressed 16-bit TIFF images to remove image noise caused by high ISO sensitivity.

4. Save the result without image noise in uncompressed 16-bit TIFF format as well.

5. Open the four noise-free 16-bit uncompressed TIFF images with a stitching program that supports the Panorama Tools.

6. In the image source photographed by the device of the present invention, all four digital cameras do not fit the Nodal Point, so when stitching in the stitching program, Parallax Error is greatly generated. This can be minimized.
