Description

[0001] The present invention relates to a vr tourism advertisement method using a drone,

The present invention relates to a one-shot panoramic VR photographing apparatus, and more particularly, to a one-shot panoramic VR photographing apparatus in which a one-shot panoramic VR photographing apparatus is mounted on a supporting platform such as a camera monopod, Screen panorama VR including azimuth information can be easily and quickly photographed even in a high-altitude state.

In general, VR (Virtual Reality) is a virtual reality in which all senses (visual, auditory, olfactory, taste, tactile) of the human body are generated in a 3D virtual environment similar to the real environment created through computer graphic It is a technology that ultimately aims to maximize the utilization of information by engaging the human being in this virtual space by three-dimensionally reproducing the virtual space to the participant by making it interact with the virtual world.

 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) (360 ° horizontal or vertical), which is attached to a camera through a processing process, and then is attached to a spherical or cylindrical shape (mapping The image can be rotated, zoomed in / zoom out, and moved around the nodal point.

 This panorama VR technology is easy to operate, very inexpensive and can be introduced sooner than any other VR technology in terms of getting results in a short period of time. It can be used for existing relics, tourism, architecture, model house, interior, travel, shopping mall, It is used in various fields.

 In order to photograph the conventional panorama VR, a tripod is mounted on a floor, a horizontal system is fixed on the tripod, and a VR equipment (= A VR rotator or a panoramic head) is fixed. Finally, a digital camera is mounted on the VR rotator, the leveling system is adjusted to completely horizontally align the digital camera, the mode of the digital camera is set to the fully manual mode, After measuring exposure to the scene, make appropriate aperture, shutter speed, and ISO settings.

 Then, when the VR rotator is rotated 360 degrees, at least four to fifty images are shot. In order to produce a 360-degree panoramic VR that is not 360 degrees horizontally, the ceiling is photographed and 360 degrees To create a panoramic VR, detach the digital camera from the VR rotator, take a tripod, and shoot the bottom of the tripod.

 However, when photographing such a conventional panorama VR, first, the time required for mounting the tripod, the leveling instrument, the VR rotator, and the digital camera, the accurate leveling time using the leveling system, The time taken to rotate the camera 360 degrees, the time taken to take the digital camera off the VR rotator and take the time to shoot the floor manually, and the second, do. That is, for example, when a large object such as a bus passes through a VR camera, it is difficult to include all of the objects in the captured image.

Third, while panorama VR is a static space that does not have objects moving on the spot like facility introduction, it is now possible to put virtual scenes such as festivals, events, and events into a panorama VR, However, in the conventional method as described above, it is difficult to capture the moment of the scene due to a lot of space and time constraints.

 Fourth, it is difficult to accurately grasp the scene position because the azimuth point is not included in the panorama VR. Fifth, because the general tripod is used, the height of the nodal point, which is the shooting point of the camera, can not be raised above a certain height. There is a problem in that when shooting is impossible, that is, when there is a barrier higher than the eye level of a person like a wall at a shooting site, when the user wants to shoot scenery beyond the wall, the user can not shoot.

 In order to solve the above problems, various panoramic VR devices have been introduced in the market, but most of them are for 360 ° panoramic VR except ceiling and floor, There is a problem that the resolution and the image quality are very poor when the full-screen panorama VR having high image quality is displayed on the internet.

 The one-shot panoramic VR photographing apparatus of the present invention is a device for supporting a support base 10 in a stable state on a bottom surface of a photographing base 10 at the lower end of a support rod 10 having a rod shape capable of being stretched and stretched such as a camera monopod or an antenna A spiral groove is formed on the outer peripheral surface of the lower end of the support base 10 as in the embodiment of the present invention and the upper center of the support member 20 The holding member 20 may be detachably coupled to the lower end of the support table 10 by forming a fixing piece 22 having a helical groove corresponding to the spiral groove at the lower end of the support table 10, The reason why the support member 20 is detachably coupled to the lower end of the support frame 10 is that when the panoramic VR is taken, This is because the panoramic VR can be photographed in a state in which the operator holds the support pedestal 10 without using the support member 20 by hand.

 The center of the VR head case 30 is detachably coupled to the upper end of the support frame 10. At this time, a spiral groove is formed on the upper outer circumferential face of the support frame 10 as in the embodiment of the present invention, The VR head case 30 is formed at the center of the VR head case 30 with a fastening hole 32 to be coupled with the spiral groove at the upper end of the VR head case 30 so that the VR head case 30 can be detachably coupled Or may be detachably coupled by other methods.

 The VR head case 30 is formed with a plurality of fixing slots 34 at intervals of 90 degrees around the fixing holes 32. A measurement graduation 36 is formed on one side of each of the fixing slots 34, And a digital camera 40 on which a fish-eye lens 42 having an angle of view of 180 degrees is mounted, is mounted on the upper surface of each of the fixed elongated holes 34 of the VR head case 30, And the camera mount 50 is formed so that the direction of the digital camera 40 is oriented at least upward by 5 degrees when the digital camera 40 is attached to the camera mount 50 , Which is to completely cover the ceiling portion when photographing.

 Each of the camera mounts 50 includes a horizontal mount 52 for supporting the lower end of each digital camera 40 and a plurality of digital cameras 40 And a vertical mounting table 54 for supporting a rear end surface of the VR head case 52 and a vertical mounting table 54 for covering the rear end surface of the VR head case 52. In the center of the horizontal mounting table 52, The VR head case 30 is provided with a positioning hole 56 communicating with the fixed elongated hole 34 of the VR head case 30 so that a fastener 70 made of a butterfly bolt passes through the fixed elongated hole 34 of the VR head case 30, The mounting position of the camera mount 50 mounted on the VR head case 30 is arbitrarily fixed as it is inserted into the position adjustment slot 56 of the base 52 and fastened by the nut.

A fastener 72 having a fastening bolt is fastened to the digital camera 40 mounted on the vertical mount 54 of each of the camera mounts 50. The digital camera 40 And a fixing hole 58 for fixing the digital camera 40 to the camera mount 50. The digital camera 40 is mounted on the inside of the horizontal and vertical mounting bases 52 and 54 of the camera mount 50, A plurality of buffering members 60 made of a buffering material such as rubber are attached to protect the digital camera 40. A camera release 80 electrically connected to the digital camera 40 is installed on one side of the support table 10 to photograph four digital cameras 40 in one shot, The VR head case 30 is detachably attached to the upper end of the VR head case 30 by a pair of coupling members 100 to which a case cover 90 for covering and protecting the inside of the VR head casing 30 is coupled, 30 and the outer peripheral surface of the lower end of the case cover 90 is provided with a support groove 62 having a cushioning member 62 on its inner side for supporting the end of the fisheye lens 42 of each digital camera 40, (38) and (92), respectively, and a handle (94) for gripping is provided at the upper center of the case cover (90).

 At this time, a separate pad made of rubber or the like may be attached to the outer peripheral surface of the upper end of the VR head case 30 and the outer peripheral surface of the lower end of the case cover 90 in order to eliminate a gap between the upper and lower outer peripheral surfaces.

 The horizontal pedestal 110 horizontally installed on the upper portion of the support frame 10 is adjusted to have the same orientation as the horizontal camera 120 for aligning the horizontal direction of the digital camera 40 and the direction of the digital camera 40 The compass 130 is installed side by side.

 The following points are different from the conventional panoramic VR photographing when setting the digital camera before photographing with the one-shot panoramic VR photographing apparatus of the present invention having the above-described structure.

 1. The photographing mode of the digital camera 40 is set to the iris mode (A) instead of the full manual (M) mode.

 - When shooting in normal panorama VR mode, the reason for shooting in full manual mode is that if the overlapping images have different exposure, the blurring process shows a sudden change in brightness at the overlapping part of the images, which is very unnatural and unrealistic in actual panorama viewer program .

 In the apparatus of the present invention, when the camera is shot in the iris mode (the aperture value is set to be the same for all four digital cameras), each digital camera performs an appropriate exposure measurement for each digital camera.

 In other words, images taken on each digital camera may look darker in some images because they have different exposures from each other, but the same parts may look darker in other images, but the different problems are solved through the general panorama image blending function The number of images that can be taken when shooting a typical panorama VR is more than 10, depending on the model of the digital camera and the type of lens.

 In general, the two overlapping images taken by the two consecutive photographs are about 30%. In the apparatus of the present invention, four 180 degree fisheye lenses 42 can theoretically include all directions 360 degrees up, down, left and right .

 That is, all the objects on the scene can be said to be photographed twice by the digital camera 40. Since the photographs are photographed in the iris mode, when the two photographed objects are compared with each other, the exposure is different. However, Is much more flexible for natural exposure correction of the final panoramic VR image than blending of the normal panorama VR.

 In addition, by setting the digital camera 40 to the iris mode, the problem of low dynamic range of the digital camera, which is a typical problem in panoramic VR photographing, can be solved naturally, and the panoramic VR do. For example, it is possible to mount the apparatus of the present invention in a car and rapidly expose it to a suitable exposure for each scene exposure in continuous shooting while moving at a high speed.

 2. Increase the ISO sensitivity sufficiently to ensure sufficient shutter speed to match the lighting conditions, depending on the weather and time of day.

- Normally, when taking a picture, it is necessary to shoot ISO at least as low as possible to get clear pictures without noise. In the conventional conventional panoramic VR system using the VR rotator, since the tripod is fixed to the digital camera, even if the shutter speed is slowed down when the ISO is minimized, it is not a problem. In the present invention, In order to overcome this problem, it is necessary to increase the ISO sensitivity according to the lighting condition of the scene during shooting to obtain sufficient shutter speed to solve the problem.

 3. Set the image format to RAW instead of JPEG.

 - In conventional conventional panorama VR photography, it is common to shoot in RAW rather than JPEG to produce a full-screen full-screen VR. In general, the reason for shooting in RAW, rather than JPEG, is that the width of the posterior (white balance, color correction) is much wider than that of JPEG when the shot is taken after shooting.

 In the conventional conventional panoramic VR system, the photographing mode is taken in a fully manual mode. However, in the apparatus of the present invention, since the photographing is performed in the iris mode, overlapping portions of the four images obtained after photographing have different exposure values. At this time, there is a difference in color and brightness between the images, which overlap each other. This problem can be solved by the panorama blending process as described in the above 1.

 When the blending process is performed, color information of overlapping portions is obtained and blended in each image. The more the information about the color is, the more natural (no sharp difference in color or brightness) the panoramic VR image can be obtained .

<47> That is, the more color information there is, the more advantageous it is, that is why it is not RAW but JPEG. JPEG is an image format of 8-bit compression format. RAW is a pure CCD data information that is not processed by digital camera CCD. Therefore, RAW files obtained after shooting should be processed as follows to perform high quality panoramic VR image Can be obtained.

 - The RAW file is subjected to chromatic aberration and exposure compensation (correction for too dark and too bright areas) in software and saved in 16 bit uncompressed TIFF format. Unlike JPEG, the 16-bit TIFF image format has no damage to image data.

 - Use noise reduction software such as Noise Ninja to remove noise caused by high ISO sensitivity in 16bit TIFF and also remove it in 16bit TIFF format.

 - Panoramic stitching and blending with noise-free 16-bit TIFF image to get the final panorama VR image.

 Meanwhile, in order to photograph a horizontal panorama VR including azimuth information using the one shot panoramic VR photographing apparatus of the present invention, four camera mounts 50 fixed on the upper surface of the VR head case 30 After attaching the digital camera 40 equipped with the fisheye lens 42 having the angle of view of 180 degrees in the up and down and left and right directions,

The VR head case 30 is fixed to the upper end of the support frame 10 and then the height of the support frame 10 is adjusted to a desired height so as to be stretchable. When the user wishes to photograph a VR having a higher level than the height of the support 10, the extension support 10 is attached to the support 10, and then the support 10 is vertically installed.

 Then, when it is desired to include azimuth information at the time of photographing, the support table 10 is rotated so that a specific direction is applied to a specific digital camera direction with reference to the compass 130 installed on the horizontal support 110 on the support table 10 The horizontal direction is checked while confirming the leveling system 120 installed side by side with the compass 130 on the horizontal support 110 and then the digital camera 100 installed on one side of the support stand 10 The four digital cameras 40 can be actuated at the same time as the camera release 80 electrically connected to the digital camera 40 is pressed.

 Further, in order to photograph a desired point in a difficult situation in which the support stand 10 of the one-shot panoramic VR photographing apparatus of the present invention can not be erected or a tripod can not be installed, the panoramic VR photograph It should be noted that the one-shot panoramic VR photographing apparatus of the present invention weighs about 5 kg

It is needless to say that the length of the support member 10 should be adjustable within a range that the photographer can afford.

 The above-described photographing method is similar to the above-described horizontal photographing method except that the photographing is performed by directly holding the support stand 10, but in the case where it is desired to include azimuth information, the following process is performed.

After confirming 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, the direction of the camera 1) is applied to the direction of the specific digital camera .

 - Care is taken not to rotate the support 10 at the current point of the photographer, and the support 10 is tilted in the direction of the point to be photographed. Note that if the support 10 is tilted by 90 degrees or more, Be careful not to exceed 90 degrees because it changes backward.

 In addition, it should be considered that some errors may occur in the azimuth angle because shaking may occur during the tilting of the support table 10, and if the digital camera 40 is photographed in this manner, Panorama VR can be programmed horizontally in the program. If it is a commercial program using Panorama Tools, an open source library developed by Dr Helmut Dersch of Germany, it is possible to program the panorama VR image source You can freely adjust the level by dragging with the mouse.

 On the other hand, the method of producing the 360-degree panoramic VR using the image source photographed by the one-shot panoramic VR photographing apparatus of the present invention does not deviate greatly from the conventional conventional method of producing the panoramic VR image. However, We should be more careful than the hour.

 - To make the color correction to be as natural as possible because of different color difference due to exposure and exposure difference, work with uncompressed 16 bit image except the final panorama VR image.

 - It is a stitching program that supports Lens Calibration, minimizing Parallex Error even if the Nodal Point does not match each other.

 - Use the Panorama Tools to level the panorama VR.

 In addition, the work of producing 360 degree panoramic VR image with the photographed image source is as follows.

 1. Use the RAW professional correction software to make the following corrections to the four captured RAW images.

 - Chromatic Abberation

 - Exposure compensation (compensation for overexposure and overexposure)

 - Vignetting correction

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

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

 4. Save the resulting image as uncompressed 16-bit TIFF format.

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

 6. Since the four digital cameras can not match the nodal point in the image source photographed by the apparatus of the present invention, when the stitching is performed in the stitching program, a parallax error occurs largely. In this case, It can be minimized.
