Description

  The present invention relates to a three-dimensional image automatic generation apparatus.

  The use of electronic commerce, virtual museums, digital encyclopedias, and electronic catalogs using digital media such as the Internet and CD ROM is gradually increasing. In such a case, a binocular solid that has an actual object in front of the eyes as well as a planar image like a photograph so that the visual approach to the object through virtual reality can be performed more effectively. It is necessary to provide a sufficient three-dimensional effect together with a three-dimensional image (or only a three-dimensional image uniquely) for allowing a user to freely select a direction and posture for viewing an object.

  Thus, the use of 3D content is gradually increasing in order to achieve various purposes such as educational effects and provision of practical information on products. However, in the conventional three-dimensional content providing method, an operator passively shoots an object to be photographed (for example, a sculpture, a product for sale, etc.) from many angles, and then synthesizes the photographed photographs to create one 3 A method for generating a three-dimensional image, a method for capturing a moving image, and providing a moving image file are provided.

There is a problem that the number of photographs to be taken for creating a three-dimensional image is large, requiring a long time for photographing, and complicating the process of generating a three-dimensional image, resulting in an increase in the cost of generating a three-dimensional image. There was also a point. Also, when shooting all shooting objects multiple times, if there is a photo that does not match the center point of the photo, it may be necessary to start the shooting from the beginning. In the process of re-photographing various angles, there was also a problem that work errors occurred due to human vision and camera lens angle.

  Compared to this, the method of shooting moving images and providing moving image files can be provided as a single electronic file after the shooting object is shot continuously using excellent camera material. Although there are advantages in that the generation time is shortened and the electronic file generation process is easy, there is a problem that a consumer cannot freely obtain an image of a desired angle. In addition, since the capacity of an existing moving image file is very large, a web server (Web Server) that provides the file may not operate normally (for example, down). There were limits to publicizing the material.

  The present invention can provide an automatic three-dimensional image generation apparatus that can easily generate a three-dimensional image and can save cost and time.

  Referring to FIG. 1, a 3D image automatic generation apparatus according to the present invention includes an image capturing unit (10) and an image management apparatus (30).

  The image photographing unit (10) photographs a photographing object in a state corresponding to a control signal (that is, a turntable rotation speed control signal, a turntable rotation angle control signal) of the image management device (30). The digital image (for example, an image in JPEG format) is transmitted to the image management apparatus (30). The detailed configuration of the image capturing unit (10) will be described later in detail with reference to FIGS. 2 to 6, and the overall configuration of the three-dimensional image automatic generation apparatus will be described.

  The image management device (30) includes an image shooting control unit (33), an image shooting storage unit (31), a three-dimensional image generation unit (37), a three-dimensional image storage unit (43), a transmission / reception unit (41), and a three-dimensional image.

Of course, although not shown in FIG. 1, a transmission / reception unit that relays data transmission / reception between the image capturing control unit (33) and the image capturing unit (10) may be further included.

  The image photographing storage unit (31) stores a plurality of digital images photographed by the image photographing unit (10) in a state corresponding to the control signal of the image photographing control unit (33). The image shooting storage unit (31) can further store shooting state information corresponding to each digital image (for example, rotation angle of the turntable at the time of shooting, shooting surface information of the subject).

  The three-dimensional image generation unit (37) processes a plurality of digital images stored in the image photographing storage unit (31) to generate one electronic file (for example, an NVR format file). Of course, instead of generating a single actual 3D image, a digital image is combined to make it look like a 3D image so that it can be seen by the consumer's eyes. A method for enabling recognition can also be applied. An NVR format electronic file can be compressed as an electronic file in a compressed form to about 200 / l or less, and a plurality of digital images can be processed and modified to be recognized as a single moving image. It is an electronic file. Therefore, before generating an NVR format electronic file, the digital image background, center axis, etc. stored in the image capture storage unit (31) is corrected (for example, center axis alignment) to expand multiple digital images to multiple An operation such as performing may be preceded.

  The three-dimensional image storage unit (31) performs a function of storing the NVR format electronic file generated by the three-dimensional image generation unit (37). Of course, the image photographing storage unit (31) and the three-dimensional image storage unit (43) may be integrated as one storage unit.

  The transmission / reception unit (41) transmits the NVR format electronic file stored in the three-dimensional image storage unit (43) to the external web server (49) (for example, an electronic commerce server), and the external web server (49). The function to receive the request from is performed.

  The three-dimensional image display control unit (47) causes the generated electronic file in the NVR format to be displayed on the display unit (45) in the form of a three-dimensional image, and also controls control commands (for example, The image is converted so as to correspond to the left / right rotation, enlargement / reduction, and the like, and the display unit 45 performs a function.

  The display unit (45) is a unit for displaying a three-dimensional image, and the input unit (35) is a unit for inputting a display control command or the size of an object to be photographed by an operator. FIG. 1 assumes only a case where a three-dimensional image is displayed through a display unit (45) included in the image management device (30). However, a display device different from the image management device (30) is provided. Of course, it is possible to display a three-dimensional image through the display device.

  The control unit (39) automatically generates and provides a 3D image, and the image shooting control unit (33), the image shooting storage unit (31), and the 3D image generation unit (37). The three-dimensional image storage unit (43), the transmission / reception unit (41), the three-dimensional image display control unit (47), and the like are controlled.

  The configuration of the three-dimensional image generation apparatus illustrated in FIG. 1 is merely an example for explaining the present invention, and some of the components (for example, a display unit, an input unit, etc.) included in FIG. It can be omitted or combined with an external device (eg, a computer) to perform the same function. Further, the image management apparatus (30) according to the present invention does not have a separate hardware configuration, and can be embodied as software installed and operated on a computer or the like.

  Hereinafter, an embodiment of the image photographing unit (10) of the three-dimensional image automatic generation apparatus will be described with reference to FIGS.

  Referring to FIG. 2, the image capturing unit (10) according to an embodiment of the present invention includes a case (19) having a certain size, and a subject (not shown) is placed inside the case (19). A turntable (37) positioned, an illumination unit (17) for irradiating light to the subject, and a camera unit (15) for photographing the subject are provided. In addition, a background portion (21) serving as a background at the time of photographing is located around the turntable (27). The illumination unit (17) and the camera unit (15) are fixed to the panel (13), and each panel (13) is supported by the frame (11).

  In the image photographing unit (10) according to the present embodiment, the camera unit (15) and the illumination unit (17) are arranged horizontally and vertically with respect to the rotation axis of the turntable (27) and have a predetermined inclination angle. It is characterized in that it is arranged as Therefore, after the subject is placed on the turntable (27), the camera unit (15) is used to take images from various angles while rotating the turntable (27) (FIG. 4). (See) 3D image can be easily generated.

  The turntable (27) has a flat horizontal surface (29) on which the subject is located, and rotates around a certain rotation axis (X). The turntable (27) is rotated by a fixed drive device such as an electric motor, and the rotation speed and rotation angle are controlled by the control signal of the control unit (39). The rotation axis (X) is perpendicular to the horizontal plane (29), but the turntable (27) rotates about the rotation axis (X).

  The subject is located on the horizontal plane (29) and has a certain color, for example, white. The reason why the horizontal plane (29) exhibits a certain color such as white is to prevent the horizontal plane color from being projected onto the subject or the like. The horizontal surface (29) is exposed to the outside through a center hole (25) formed in the background portion (21), and the height of the horizontal surface (29) is substantially the same as the upper surface of the horizontal portion (26). is there. This is to prevent generation of a shadow on a part of the turntable (27) protruding outside the center hole (25) due to light irradiation by the illumination unit (17).

  The camera unit (15) and the illumination unit (17) are positioned perpendicularly or parallel to the rotation axis (X) and have a certain inclination angle (see FIG. 4) and are spaced apart from the turntable (27) by a certain distance. Being located. Since the camera unit (15) arranged in this way shoots the subject at various angles at the same time, it is easy to generate a three-dimensional image. The camera unit (15) captures an image of the subject and generates a digital image after the turntable (27) is rotated at a certain angle by a control signal received from the image capturing control unit (31). The camera unit (15) may be connected through a cable to receive a control signal from the image capturing control unit (31) and transmit the captured image to the image capturing control unit (31). The camera unit (15) may be a general CCD (Charged Coupled Device) or a CMOS (Complementary Metal-Oxide Semiconductor) camera module, but is not limited thereto.

  Referring to FIGS. 3 to 4, the camera unit (15) includes a plurality of cameras fixed to the panels (13a, 13b, 13c, 13d). The camera unit (15) includes a camera module (15a) arranged flat and perpendicular to the rotation axis (X) of the turntable (27), a camera module (15d) arranged parallel to the rotation axis (X), and a rotation axis. (X) and a camera module (15b, 15c) arranged at an imaging inclination angle. The center line of each camera module (15a, 15b, 15c, 15d), that is, the line passing through the center of the lens of the camera module and the center axis (X) are all in the same plane. That is, the respective camera modules (15a, 15b, 15c, 15d) are all located on a straight line when viewed from the direction of the arrow (Y) in FIG. 4, but this provides a more accurate image of the subject. Because.

  Referring to FIG. 4, each camera module (15 a, 15 b, 15 c, 15 d) is disposed with a shooting inclination angle of about 30 ° with respect to the adjacent camera module. The camera module (15c) is positioned with an imaging inclination angle of 30 ° with respect to the central axis (X), and the adjacent camera module (15b) has an imaging inclination of 60 ° with respect to the central axis (X). Arranged with corners. Accordingly, the camera modules (15a, 15b, 15c, 15d) according to the present embodiment have a form arranged along a part of a regular dodecagon. Of course, this invention is not limited to this, You may arrange | position along a part of regular n square (n is a natural number of 4 or more) as needed.

  As shown in FIG. 3, a pair of illumination units (17) are arranged on the left and right of the cameras (15a, 15b, 15c, 15d). The illumination unit (17) irradiates the subject with certain light, but may be a general light emitting diode (Lighting Emitting Diode). The illumination unit (17) is also located on a straight line when observed from the direction of the arrow in FIG. The illumination unit (17) is horizontal with the central axis (X) together with the camera unit (15) (17a), is perpendicular (17d), or has a constant illumination inclination angle (as in FIGS. 3 to 4). 30 ° and 60 °).

  In this embodiment, the illumination unit (17) is arranged on the same plane as the camera unit. However, the present invention is not limited to this, and the illumination inclination angle and the imaging inclination angle are made different as necessary. Needless to say, it may be arranged. Moreover, although the illumination part (17) which concerns on a present Example is arrange | positioned at right and left of a camera module (15a, 15b, 15c, 15d), the upper and lower sides of a camera module (15a, 15b, 15c, 15d) and It may be arranged in various ways as needed, such as left and right.

  As shown in FIG. 4, the background portion (21) is spaced apart from the camera portion (15) and the illumination portion (17) by a certain distance, and faces the camera portion (15) around the turntable (27). Located to be. The background portion (21) prevents an image from being generated in the background of the subject when the camera portion (15) captures the subject, thereby generating an accurate image of the subject. Referring to FIG. 5, the background part (21) includes a peripheral part (23) having a constant radius of curvature and a horizontal part (26) formed in the horizontal direction at one end of the peripheral part (23).

  The peripheral portion (23) has a constant radius of curvature and is positioned vertically, and becomes a background for the subject when the camera portion (15) captures the subject. Since at least the inner surface of the peripheral portion (23) exhibits the same color, for example, white as a whole, the color of the inner surface of the peripheral portion (23) can be prevented from being projected onto the subject. As shown in FIG. 5, a round portion (24) is formed at the connecting portion between the peripheral portion (23) and the horizontal portion (26). A round part (24) prevents generation | occurrence | production of a shadow in the connection part of a horizontal part (26) and a peripheral part (23) by smoothly connecting the lower end part of a peripheral part (23), and a horizontal part (26). .

  In the present embodiment, the peripheral portion (23) has a constant radius of curvature. However, the present invention is not limited to this, and any shape can be used as long as it does not generate a shadow and becomes a background for the subject. Is possible. For example, the perimeter (23) can be fabricated to have a planar or semi-spherical shape.

  The horizontal portion (26) extends in the horizontal direction from the lower end portion of the peripheral portion (23) and includes a center hole (25). In order to prevent the horizontal surface (29) of the turntable (27) from projecting to the outside through the center hole (25) and causing the shadow by the turntable (27), the horizontal surface (29) and the horizontal portion ( 26) can be the same or substantially the same height. The color of the upper surface of the horizontal portion (26), that is, the surface that can be photographed by the camera portion (15) can also be the same color as white.

  Hereinafter, the photographing method of the image photographing unit (30) will be described with reference to FIG.

  When the control signal is transmitted from the image capturing control unit (33), the turntable (27) rotates at a constant angle and speed. At this time, the illumination unit (17) can always irradiate the subject with light, or can irradiate light only when the camera unit (15) captures the image. When the rotation of the turntable (27) is completed, each camera module (15a, 15b, 15c, 15d) is positioned in a line on a constant meridian with respect to the subject. That is, as shown in FIG. 4, each camera module (15a, 15b, 15c, 15d) is arranged on four latitude lines with respect to the subject. In addition, each of the camera modules (15a, 15b, 15c, 15d) captures an image of the subject relative to each latitude line, thereby completing the capturing of one meridian.

  In addition, when a control signal is transmitted from the image capturing control unit (33), the turntable (27) rotates at a certain angle in order to capture an image of another meridian of the subject. The rotation angle can be determined by the size and shape of the subject. When the turntable (27) is fixed, each camera module (15a, 15b, 15c, 15d) captures images of four latitude lines with respect to the subject. When such a process is repeated and the turntable (27) makes one turn, photographing is completed.

  Hereinafter, a method of generating a three-dimensional image with the automatic three-dimensional image generation apparatus according to the present invention will be described with reference to FIGS. The three-dimensional image automatic generation method according to the present embodiment is convenient to use because the subject is photographed, the image is processed, the three-dimensional image is generated, and the three-dimensional image is automatically stored and transmitted. There is a feature in a certain point.

  Referring to FIG. 7, in step S10, in the image management apparatus (30) of the three-dimensional image generation apparatus, an administrator who wants to generate a three-dimensional image of a subject specifies a shooting target and receives an operation start command. The subject may be a product for sale, a facial image for shaping, a sculpture work, and the like. In this case, since the face image for molding may require higher precision than the product for sale, it is necessary to take a large number of photographic images with higher precision.

  In step S15, the image management device (30) extracts operation characteristics (ie, turntable rotation angle, number of times of photographing, etc.) specified in advance corresponding to the subject specified in step S10. For example, in the case of a facial image for molding, it may be specified in advance that images for 36 meridians are taken while rotating by 10 ° at each rotation of the turntable.

  In step S20, the image management apparatus (30) determines whether or not a precision photographing request is input from the administrator. The request for precise shooting is to allow a greater number of photos to be taken. When the precision photographing request is input, the image management device (30) updates the operation characteristics (for example, the rotation angle of the turntable, the number of photographing, etc.) extracted through step S15 in step S25, and proceeds to step S30. . However, if the precise photographing request is not input, the process immediately proceeds to step S30. In step S30, the image management apparatus (30) transmits an operation control signal (that is, a turntable rotation speed control signal and a turntable rotation angle control signal) to the image photographing unit (10).

  The image capturing unit (10) receives the operation control signal from the image management device (30) in step S35, and proceeds to step S40 to adjust the state of the image capturing unit in accordance with the received operation control signal. For example, according to the operation control signal, the image photographing unit (10) can stand by at a rotation speed of the turntable (27) or a state rotated by a certain angle. In this step, the state of the initially photographed image may be inspected, and the position, situation, etc. may be readjusted according to the state of the image, or automatic photographing start may proceed.

  In step S45, the image capturing unit (10) captures a digital image adjusted in step S40, and proceeds to step S50 to transmit the captured digital image to the image management apparatus (30).

  In step S55, the image management apparatus (30) receives and stores the digital image from the image photographing unit (10). Thereafter, the image management apparatus (30) processes the digital image stored in step S57. Such a processing method is shown in FIG.

  Referring to FIG. 8, in the method of processing a digital image, first, the digital image stored in step 57a is automatically corrected. That is, using functions such as chroma-key, size correction, exposure correction, color correction, white balance correction, automatic centering, and auto focus. Correct the image to the optimum state.

  In step 57b, a three-dimensional VR (virtual reality) image function such as vertical and horizontal rotation of the screen, enlargement, and an animation function is added. Thereafter, in step 57c, after compressing the digital image to which the automatic image correction and the three-dimensional VR image function are added in step 57a and step 57b, the loading speed and the like are adjusted. In step 57d, the format of the VR file is determined. The VR file can be processed into various file formats such as NVR, SWF, M3D, IGES format, etc., but is not limited thereto.

  After the digital image processing is completed, it is determined in step S60 whether or not all of the image shooting for the subject has been completed. If all the image capturing has not been completed, the process proceeds to step S65, the operation control signal is updated, and the process proceeds again to step S30. However, if all of the image shooting has been completed, the process proceeds to step S70. Through step S30 to step S65, the image photographing unit (10) can photograph all the parts of the subject (for example, the back surface) as the turntable (27) rotates.

  In step S <b> 70, the image management apparatus (30) generates one three-dimensional image using a plurality of photographed digital images. As a method of generating one 3D image, a method of generating an image by combining various types of files and compressing them can be applied. Of course, instead of generating a practical one-dimensional image, a method of concatenating a plurality of digital images can be applied to make it look like a single three-dimensional image to the consumer's eyes. . The image composition process for generating one 3D image is a process of correcting captured image data, a process of inputting corrected image data, and a region where a subject is present and a background region on the input digital image. The process of removing the background area, the process of matching the center point of the digital image where only the subject exists, the process of adding multi-streaming functions (eg, enlargement, reduction, animation, etc.) to the regularly aligned data, the recording process In addition, a process of compressing (for example, generating an NVR file) to an optimum dose by applying MPEG technology to each digital image at the same time as recording may be included.

  In step S75, the image management apparatus (30) determines whether or not the 3D image display request generated by the administrator is input. When a 3D image display request is input, the process proceeds to step S80 and the generated 3D image is displayed on the display unit (45). However, if the 3D image display request has not been input, the step ends.

  In step S85, the image management apparatus (30) determines whether a request for changing the display state of the three-dimensional image displayed by the administrator is input. When the display state change request is input, the process proceeds to step S90, and the three-dimensional image whose display position is changed is displayed on the display unit (155). However, if the display state change request has not been input, the step ends.

  FIG. 9 illustrates a state in which the three-dimensional image is displayed on the display unit (45). Referring to FIG. 9, the 3D image display screen includes a 3D image display area (41) and a function button area (43). In the function button area (43), an enlargement button for enlarging and showing the 3D image shown in the 3D image display area (41), a reduction button for reducing and showing the 3D image, and a 3D image A rotation button for changing the display surface (ie, rotating up, down, left and right) and a close button for displaying another image can be included. That is, the image management apparatus (30) according to the present invention can rotate the pattern of the subject up, down, left, and right by controlling the mouse so that enlargement, animation, and the like appear in a portion where multi-streaming is applied. can do. Of course, although not shown in FIG. 7, a process of transmitting the 3D image generated through step S70 to the external web server 49 through the communication network may be further included.

  In addition, a three-dimensional image file generated by a user's operation or a predetermined control signal set in advance can be stored in an external mobile storage device such as a memory stick or a mobile hard disk.

  Although the embodiments of the present invention have been described above, various changes and modifications of the present invention should be construed as belonging to the scope of the present invention as long as they embody the technical idea of the present invention.
