Description

Technical Field

[0001] The present invention relates to a support device for a photographing apparatus used in photogrammetry for generating a three-dimensional photograph by analyzing parallax information from a plurality of two-dimensional photographs. In particular, it relates to a support device used in a space with a ceiling view (indoors such as underground shopping malls, arcades, inside churches, inside shrines and temples, inside shopping centers, etc., outdoors where trees are lush and it is like a tunnel, etc.), especially at a location where an image of the ceiling view is required.

Background Art

[0002] With the recent improvement in image processing technology and computer processing speed, photogrammetry has begun to attract attention. Photogrammetry is a technology that precisely digitizes the images and positions from photographs taken from various angles and reproduces a real three-dimensional object from them. In order to facilitate photographing for photogrammetry, for example, Patent Document 1 discloses a photogrammetry photographing apparatus for a subject such as a person using a camera unit having a plurality of cameras. Patent Document 2 also discloses a pan-tilt head on which a plurality of cameras facing different directions can be mounted.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, the photogrammetry photographing apparatus of Patent Document 1 is an apparatus in which a person or the like enters a large and fixed apparatus for photographing. Further, Patent Document 2 is a pan-tilt head for producing a simple three-dimensional image and is not suitable for a pan-tilt head for photogrammetry considering the reflection of an operator or the like.

Means for Solving the Problem

[0005] Therefore, the present invention provides a support device that can be carried by an operator and to which a photographing camera can be attached.

[0006] The support device of the present embodiment includes a pair of shoulder portions that contact the shoulders of the operator, a pair of first frames that extend forward and backward from the pair of shoulder portions, a pair of second frames that are disposed above the pair of first frames and extend in parallel with the pair of first frames, at least six first mounts for a photographing camera that are disposed on the pair of first frames, at least six second mounts for a photographing camera that are disposed on the pair of second frames, and at least six third mounts for a photographing camera that are disposed on the pair of first frames or the pair of second frames.

[0007] Each of the pair of first frames and the pair of second frames of the support device has a circular or polygonal cross-section, or is a flat plate with a rectangular cross-section. Also, the pair of first frames and the pair of second frames are connected by a connecting portion that extends vertically. Each of the pair of first frames and the pair of second frames extends 50 cm to 100 cm forward from the shoulder portion and 50 cm to 100 cm backward from the shoulder portion. The first mounts and the third mounts are preferably disposed at positions 50 cm to 100 cm away from the shoulder portion.

[0008] When eight second mounts are arranged, it is preferable that a region having a predetermined width in the horizontal direction is formed in the first frame or the second frame. Also, one of the pair of first frames or the pair of second frames is preferably connected to the other of the pair of first frames or the pair of second frames by a flexible or foldable connecting portion.

Modes for Carrying Out the Invention

[0011] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In this specification and the drawings, components having substantially the same functional configuration are denoted by the same reference numerals, and redundant descriptions are omitted. Also, in each drawing, the members are not drawn to actual dimensions in order to emphasize the members.

[0012] <<First Embodiment>> <Overview of the Support Device> FIG. 1 is a perspective view of a support device 100 according to the first embodiment, showing a state where an operator is carrying the support device 100 on the shoulder. The support device 100 can be attached with at least one or more of a photographing camera CA (CA1, CA2, CA3), a lighting light LT, and the like. In the following description, in the basic posture when the support device 100 is carried by the operator, the ceiling side is defined as up (+Z axis) and the ground side is defined as down (-Z axis). The direction in which the gripping bar 19 that the operator grips in front of himself / herself is arranged is defined as front (+Y axis), and the opposite side is defined as rear (-Y axis). And in the direction of the operator's right hand, the back side of the paper surface of FIG. 1 is defined as right (-X axis), and the front side of the paper surface is defined as left (X axis).

[0013] The support device 100 of the present embodiment supports a camera used for photogrammetry in which an operator walks around a place and generates a three-dimensional photograph of the surroundings. In particular, it is used in outdoor areas where trees are overgrown and it is like a tunnel, indoor spaces with ceilings (such as underground shopping streets, arcades, inside churches, inside shrines and temples, inside shopping centers, etc.), where the operator walks around, not only for landscapes or walls and floors or the ground that spread horizontally, but especially for places where an image of the ceiling landscape is required. Also, since the operator carries the support device 100 and walks around, it is preferably formed of a material that is as light as possible.

[0014] The size of the support device 100 is configured to fit within, for example, 100 cm to 200 cm in the front-rear direction (Y-axis direction), 25 cm to 60 cm in the left-right direction (X-axis direction), and 30 cm to 60 cm in the height direction (Z-axis direction). The reason for such a size is that if it is less than 100 cm in the front-rear direction, the head and legs of the operator will be reflected in the angle of view range of the imaging camera CA, and if it is more than 200 cm, the self-weight of the support device 100 will increase and it will be difficult to handle in narrow alleys etc. Also, if it is less than 25 cm in the left-right direction, the operator will not be able to carry it on the shoulder, and if it is more than 60 cm, it will be difficult to carry on the shoulder. Further, if the height direction is less than 30 cm, the head of the operator will be reflected in the angle of view range of the imaging camera CA, and if it is more than 60 cm, it will be difficult to handle the support device 100.

[0015] The imaging camera CA (including still cameras and video cameras) and the illumination light LT attached to the support device 100 can be freely changed according to the application. The illumination light LT is not required in a bright space, and in a dark space, one or more illumination lights LT can be appropriately arranged or changed to a brighter illumination light LT.

[0016] The support device 100 includes a pair of shoulder portions PT that contact the shoulders of the operator in order for the operator to support the weight of the support device 100. The support device 100 also includes a pair of first frames 10D that extend forward and backward from the pair of shoulder portions PT, and a pair of second frames 10U that are arranged above the pair of first frames and extend in parallel with the pair of first frames 10D. Each of the pair of first frames 10D and each of the pair of second frames 10U are connected by a front connecting rod 15 formed in the forward direction and a rear connecting rod 15 formed in the rearward direction.

[0017] The first frame 10D on the left is connected to the first frame 10D on the right by a flexible or foldable joint 17. Also, the second frame 10U on the left is connected to the second frame 10U on the right by a flexible joint. In FIG. 1, two joints are arranged above and below the rear connecting rod 15 formed in the rear direction, and the first frame 10D and the second frame 10U on the left are connected to the first frame 10D and the second frame 10U on the right.

[0018] In front of the pair of first frames 10D, gripping rods 19 for the operator to grip are respectively arranged. The operator supports the weight of the support device 100 with the shoulder and keeps the support device 100 horizontal in the front-rear direction with the gripping rods 19.

[0019] <Overview of the shoulder part> FIG. 2(A) is a plan view of the support device 100 observed from the +Z-axis direction, FIG. 2(B) is a side view of the support device 100 observed from the -X-axis direction, and FIG. 2(C) is a rear view of the support device 100 observed from the -Y-axis direction. The shoulder part PT shown in FIG. 2 is formed of an elastic member such as a rubber material, urethane, styrofoam, or a fabric material with cotton so that the shoulder does not hurt because the weight of the support device 100 is supported by the operator's shoulder. Also, so as to facilitate supporting the support device 100, it is preferable that a part of the shoulder part PT is cut out in an arc shape or a trapezoidal shape. The shoulder part PT may be fixed to the first frame 10D by an adhesive or screwing, etc., or may be removably fixed by a belt fastening.

[0020] <Overview of the frame> The pair of first frames 10D shown in FIG. 2 are formed of lightweight plastics such as polypropylene or ABS, lightweight wood, or lightweight metals such as chrome steel or aluminum alloy. In the first embodiment, an example is shown in which a flat hollow plastic having a rectangular cross-section is used. The width (in the X-axis direction) of the flat first frame 10D is, for example, 6 cm to 10 cm, and the lengths L1 and L2 of the first frame 10D in the front-rear direction extend, for example, 50 cm to 100 cm forward from the shoulder portion and 50 cm to 100 cm backward from the shoulder portion. More preferably, the forward length L1 may be 70 cm to 90 cm, and the length L2 backward from the shoulder portion may be 70 cm to 90 cm. In the first embodiment, the length of the first frame 10D is constant, but the length may be made variable. The lengths of the first frame 10D in the front-rear direction are the same, but they may be different from each other.

[0021] The pair of second frames 10U arranged on the upper side are also preferably formed of hollow plastic, wood, or lightweight metal in the same manner as the first frame 10D and are formed to have the same length. The first frame 10D and the second frame 10U are connected by a connecting portion 15 described later and are arranged parallel to each other.

[0022] <Overview of the connecting portion> The lower first frame 10D and the upper second frame 10U are connected by a connecting portion 15. The connecting portion 15 is also formed of hollow plastic, wood, or lightweight metal. The height H1 of the connecting portion 15 (exactly including the height of the first and second frames and the shoulder portion) is from 30 cm to 60 cm, preferably from 35 cm to 50 cm. If the height H1 is 30 cm or less, the top of the operator's head will be reflected in the shooting (angle of view) range of the shooting camera CA, which is not suitable. In addition, a height adjustment mechanism may be attached to the connecting portion 15 so that the top of the operator's head is not reflected from the operator's shoulder. In the first embodiment, it is connected by two rod-shaped connecting portions 15 (a pair of four) in the front-rear direction, but there may be three or more on each of the left and right sides, or it may be connected by a flat plate-shaped connecting portion 15 on each of the left and right sides extending in the front-rear direction. In addition, in order to facilitate loading in the vehicle or reduce the storage space when transporting the support device 100, the connecting portion 15 is preferably foldable. That is, it is preferable that the connecting portion 15 can be folded so that the lower first frame 10D and the upper second frame 10U are substantially in contact with each other.

[0023] <Outline of the connecting portion> The first frame 10D and the second frame 10U on the left side and the first frame 10D and the second frame 10U on the right side are preferably carried on the operator's shoulders substantially in parallel when observed from above. For this reason, at least one of the first frame 10D and the second frame 10U on the left side and at least one of the first frame 10D and the second frame 10U on the right side are connected by a connecting portion 17. In the first embodiment, the first frame 10D on the left side and the first frame 10D on the right side are not directly joined, but are connected via the rear rod-shaped connecting portion 15. Similarly, the second frame 10U on the left side and the second frame 10U on the right side are not directly joined, but are connected via the rear rod-shaped connecting portion 15. Although not depicted in FIG. 2, at least one of the first frame 10D and the second frame 10U on the right side on the front side (+Y-axis side) and at least one of the first frame 10D and the second frame 10U on the right side may be connected by a connecting portion 17.

[0024] The connecting part 17 may be a rigid lightweight plastic rod or a lightweight metal round rod, or may be a flexible string with little stretchability. In FIG. 2, the connecting part 17 is formed of a strip-shaped string. Since the connecting part 17 is formed of a strip-shaped string, it can be folded so that the left first frames 10D and 10U and the right first frames 10D and 10U overlap. In the case of a rigid metal, in order to make it easier to load the support device 100 into the vehicle or to reduce the storage space, it is preferable to have a folding mechanism so that the left first frames 10D and 10U and the right first frames 10D and 10U overlap.

[0025] <Overview of the gripping rod> The gripping rod 19 is provided in front of the pair of first frames 10D for the operator to balance the support device 100. The gripping rod 19 is preferably formed of hollow plastic, lightweight wood or lightweight metal, and preferably has a grip provided on the gripping rod so that the operator can easily grip the gripping rod 19. Further, the gripping rod 19 has a length of about 30 cm to 50 cm, and preferably has a folding mechanism or a detaching mechanism from the first frame 10D in order to make it easier to load the support device 100 into the vehicle.

[0026] <Overview of the mount> In order to facilitate photographing for photogrammetry, a plurality of mounts for attaching the photographing camera CA are arranged on the support device 100. The mounts are arranged so that the operator carrying the support device 100 is not reflected and the entire periphery of the support device 100 can be photographed.

[0027] As shown in Fig. 2(A), at least six second mounts 22 for a photographing camera are provided above the pair of second frames 10U (in the +Z-axis direction). Although not partially shown, at least six first mounts 26 for a photographing camera are provided below the pair of first frames 10D (in the -Z-axis direction). Also, the arrangement of the first mounts 26 in the XY plane is the same as that of the second mounts 22. Further, at least six third mounts 24 for a photographing camera are provided, which are arranged above the pair of first frames 10D or below the pair of second frames 10U. In the first embodiment, as shown in Figs. 2(B) and (C), the third mounts 24 are provided above the first frames 10D, and eight third mounts 24 are provided as will be described later.

[0028] The first, second, and third mounts have functions equivalent to, for example, a pan head of a tripod, and are configured such that at least the pitch direction among the roll direction, pitch direction, and yaw direction can be freely set. The reference axes of the first, second, and third mounts are preferably arranged at a predetermined angle in the horizontal direction.

[0029] <Arrangement of the photographing camera and arrangement of the mounts> For photographing to create a digital 3D model by photogrammetry, it is necessary to ensure sufficient overlap in each photograph. That is, it is preferable that the first photograph and the second photograph overlap by 60% (in the horizontal direction) or 80% (in the vertical direction) or more. Further, in order to create a more precise 3D model, it is preferable that the object to be photographed is photographed from at least three different angles.

[0030] Figure 3(A) shows the upper surface of the second frame 10U. As shown in FIGS. 2(A) and 3(A), on the upper surface of the second frame 10U, the second mounts 22 are arranged facing in the directions of 30°, 90°, 150°, 210°, 270°, and 330° with respect to the +Y-axis direction. That is, θA in FIG. 3(A) is such that adjacent second mounts 22 are each set at 60°. And the imaging cameras CA1 are arranged on the respective second mounts 22 facing obliquely upward (for example, about +45° in the pitch direction with respect to the horizontal plane). Depending on the angle of view of the imaging camera CA1, since the second mounts 22 are arranged with their orientations changed at 60° intervals, sufficient overlap is ensured in each photograph taken by the imaging camera CA1.

[0031] Also, each of the second mounts 22 is arranged at the front end and the rear end (in the Y-axis direction) of the second frame 10U. As described above, since the lengths L1 and L2 in the front-rear direction of the first frame 10D are from 50 cm to 100 cm, the arrangement of the second mounts 22 is also at a position from 50 cm to 100 cm from the shoulder portion.

[0032] Although not shown, on the lower surface of the first frame 10D, the first mounts 26 are arranged facing in the directions of 30°, 90°, 150°, 210°, 270°, and 330° with respect to the +Y-axis direction. That is, when observing the lower surface of the first frame 10D from below (-Z-axis direction), the first mounts 26 have the same arrangement as in FIG. 3(A). And the imaging cameras CA3 are arranged facing obliquely downward (for example, about -45° in the pitch direction with respect to the horizontal plane).

[0033] FIG. 3(B) is a top view of the first frame 10D. On the upper surface of the first frame 10D, eight third mounts 24 are arranged with the +Y axis direction as a reference, at intervals of θB = 45°, that is, facing in the directions of 0°, 45°, 90°, 135°, 180°, 225°, 270°, and 315°. As shown in FIG. 3(B), the imaging cameras CA are arranged on the respective third mounts 24 facing the horizontal direction. By arranging the third mounts 26 at intervals of 45 degrees and changing their orientations, sufficient overlap is ensured in each photograph taken by the imaging camera CA2. Note that at least six third mounts 24 may be provided for taking photographs for photogrammetry. Also, the second mounts 22 and the first mounts 26 may be arranged at intervals of 45 degrees like the third mounts 24, or twelve first, second, and third mounts may be arranged at intervals of 30 degrees.

[0034] <Imaging range> FIG. 4 is a diagram showing the overlapping condition in the horizontal direction (XY plane) of the imaging range when the imaging cameras CA (CA1, CA2) have a horizontal field angle of 100°. (A1) is a diagram showing the imaging range (horizontal field angle of 100°) AF of six imaging cameras CA1 attached to the upper surface of the second frame 10U, and (A2) is a diagram showing the six imaging ranges AF gathered at one point. (B1) is a diagram showing the imaging range (horizontal field angle of 100°) AF of eight imaging cameras CA2 attached to the upper surface of the first frame 10D, and (B2) is a diagram showing the eight imaging ranges AF gathered at one point. Note that when the operator moves in the +Y axis direction, since the imaging cameras CA take pictures periodically, it is drawn as a diagram showing the imaging ranges AF taken in multiple directions gathered at one point as an image.

[0035] As shown in FIG. 4(A2), sufficient overlap is ensured in the imaging range AF taken by the imaging camera CA1. As shown in FIG. 4(B2), sufficient overlap is ensured in the imaging range AF taken by the imaging camera CA2.

[0036] Conventionally, photogrammetry including the ceiling has been performed by an operator changing the angle with a hand-held camera and taking pictures of a single location from multiple angles. However, if at least six photographing cameras CA with different photographing directions are attached, just by the operator moving in one direction (for example, the +Y axis direction), photographs for photogrammetry of a space with a ceiling view can be taken.

[0037] FIG. 5 is a perspective view of the vicinity of the tip of the upper surface of the first frame 10D, and is an enlarged view including the photographing camera CA2 facing in the +Y axis direction (0° direction) and the photographing camera CA2 facing in the +45° direction adjacent thereto. FIGS. 5(A) and (B) have different perspective angles. The photographing range AF shown in FIG. 5 is a conceptual diagram showing the case where the horizontal angle of view of the photographing camera CA2 is 100° and the vertical angle of view is 65°.

[0038] Depending on the size and horizontal angle of view of the photographing camera CA, if there are a photographing camera CA2 (CA21) facing in the Y axis direction (0° direction or 180° direction) and a photographing camera CA2 (CA22) facing in the +45° direction or 225° direction, if they are not separated by a certain distance in the Y axis direction and the X axis direction, a part of the adjacent photographing cameras CA2 may enter the photographing range. For this reason, it is preferable that the photographing camera CA21 and the photographing camera CA22 are separated by 6 cm to 10 cm in the X axis direction so as to be out of the angle of view. Therefore, the width W1 of the first frame 10D is preferably, for example, 6 cm to 10 cm. Further, when the first frame 10D is rectangular when observed from the Z axis direction, the corner portion of the first frame 10D enters within the vertical angle of view of the photographing camera CA22. For this reason, as shown in FIGS. 5(A) and (B), it is preferable to form a notch portion 11 in the first frame 10D so that the first frame 10D does not enter within the vertical angle of view of the photographing camera CA22.

[0039] <Support Device of the Second Embodiment> FIG. 6 is a side view of the support device 100A according to the second embodiment. FIG. 6(A) is a plan view of the support device 100A observed from the +Z-axis direction, FIG. 6(B) is a side view of the support device 100A observed from the -X-axis direction, and FIG. 6(C) is a rear view of the support device 100A observed from the -Y-axis direction. In the support device 100 of the first embodiment, the first frame 10D, the second frame 10U, etc. were made of lightweight wood, but in the support device 100A of the second embodiment, the first frame 110D, the second frame 110U, etc. are made of aluminum frames with circular or octagonal cross-sections. Accordingly, the configurations of the connecting portions, coupling portions, etc. are also different.

[0040] <Overview of the Frame, Mount, and Shoulder Portion> The lengths and arrangements of the first frame 110D and the second frame 110U are the same as those of the first frame 10D and the second frame 10U in the first embodiment. Also, the arrangements of the first mount 26, the second mount 22, and the third mount 24 and the orientations of the respective mounts are the same as those in the first embodiment. The shoulder portion PT is formed of an elastic member such as a cylindrical rubber material or a cotton-inserted cloth material so that the weight of the support device 100 can be supported by the operator's shoulder without causing shoulder pain, and is wound around the first frame 110D.

[0041] The first frame 110D and the second frame 110U are aluminum frames with circular or octagonal cross-sections having a diameter of, for example, about 3 cm. As described in the section <Shooting Range>, the imaging camera CA2 (CA21) facing in the Y-axis direction (0-degree direction or 180-degree direction) and the imaging camera CA2 (CA22) facing in the +45-degree direction or 225-degree direction may cause a part of the adjacent imaging camera CA2 to enter the shooting range unless they are separated by a certain distance in the Y-axis direction and the X-axis direction. Therefore, the first frame 111D is formed to extend in the X-axis direction from the first frame 110D, and the width W1 from the first frame 110D to the extended first frame 111D as shown in FIG. 6(A) is, for example, 6 cm to 10 cm.

[0042] <Overview of the Connecting Portion> The lower first frame 110D and the upper second frame 110U are connected by a connecting portion 115. The connecting portion 115 of the second embodiment is composed of, for example, an aluminum frame having a circular or octagonal cross-section with a diameter of about 2 cm. The height of the connecting portion 115 is the same as that of the connecting portion 15 of the first embodiment. The connecting portion 115 is provided with a folding mechanism 116, and the connecting portion 15 can be folded so that the first frame 10D and the second frame 10U are substantially in contact with each other.

[0043] <Outline of the connecting portion> The first frames 110D and 110U on the left side and the first frames 110D and 110U on the right side are such that the second frames 110U on the left side and the second frames 110U on the right side are connected by a connecting portion 117. Further, the first frames 110D on the left side and the first frames 110D on the right side may be connected by the connecting portion 117.

[0044] The connecting portion 117 is composed of, for example, an aluminum frame having a circular or octagonal cross-section with a diameter of about 2 cm. The connecting portion 117 is provided with a folding mechanism 116, and the first frames 10D and 10U on the left and right can be folded so as to be substantially in contact with each other.

[0045] <Outline of the gripping bar> The gripping bar 119 is provided in front of a pair of the first frames 110D. The gripping bar 119 is composed of, for example, an aluminum frame having a circular or octagonal cross-section with a diameter of about 4 cm, and may be provided with a cork or rubber grip. Further, the gripping bar 119 has a folding mechanism 118, and as shown by the dotted line, it can be folded from the middle of the gripping bar 119.

[0046] <Support device of the third embodiment> FIG. 7 is a side view of the support device 100B according to the third embodiment. FIG. 7(A) is a plan view of the support device 100B observed from the +Z-axis direction, FIG. 7(B) is a side view of the support device 100B observed from the -X-axis direction, and FIG. 7(C) is a rear view of the support device 100B observed from the -Y-axis direction. Similar to the support device 100A of the second embodiment, the first frame 110D and the second frame 110U of the support device 100B of the third embodiment are aluminum frames having a circular or octagonal cross section. In the support device 100A of the second embodiment, two extended first frames 111D are provided, but in the support device 100B of the third embodiment, no extended first frame is provided. Also, the folding mechanism 116 is not provided in the connecting portion 115 and the coupling portion 117. The configuration of the other third embodiment is substantially the same as that of the second embodiment.

[0047] In the support device 100B of the third embodiment, the third mount 24 for the imaging camera CA2 is provided not only on the upper sides of the left and right first frames 10D but also on the lower sides of the left and right second frames 10U. As described in the section of <imaging range>, the imaging camera CA2 (CA21) facing in the Y-axis direction (0-degree direction or 180-degree direction) and the imaging camera CA2 (CA22) facing in the +45-degree direction or 225-degree direction may have a part of an adjacent imaging camera CA2 enter the imaging range unless they are separated by a certain distance in the Y-axis direction and the X-axis direction.

[0048] In the third embodiment, six second mounts 22 are arranged above the second frame 110, and two third mounts 24 are arranged below the second frame 110 as shown in FIGS. 7(B) and 7(C). These two third mounts are, for example, either the third mount 24 facing in the Y-axis direction (0-degree direction or 180-degree direction) or the third mount 24 facing in the +45-degree direction or 225-degree direction.

[0049] The adjacent imaging cameras CA2 (CA21) and the imaging camera CA2 (CA22) are separated from each other by 30 cm to 60 cm in the height direction (Z-axis direction), so that a part of the imaging camera CA2 does not appear in each other's images.

[0050] In the first, second, and third embodiments, although the battery power source for the imaging camera and the battery power source for the illumination light are not depicted, the support device 100 may be provided with a battery power source. Since the support device of the present disclosure can arrange an imaging camera that captures images from various angles, it is effective for photogrammetry.
