FIG. 2 is a block diagram showing the configuration of the wearable device 1. FIG. 3 is a diagram showing a state in which the wearable device 1 is worn by a user (wearer). In the present embodiment, the wearable device 1 is a necklace-type device that is worn on the user's neck, but it may be a device that is worn on another site such as the user's head or wrist.

In the following description, in FIG. 1, the up-down direction that extends vertically is referred to as the Z-axis direction, the direction in the horizontal plane that is orthogonal to the Z-axis direction, and the forward-backward direction that extends back and forth is referred to as the X-axis direction, and the Z-axis direction. A horizontal direction that is orthogonal to the direction and that extends in the left-right direction is referred to as a Y-axis direction.

As shown in FIG. 1, the wearable device 1 includes a neck mount part (hanging part) 100 having a substantially U-shape along the neck so that the wearable device 1 can be hung on the user's neck. The neck mount portion 100 is made of, for example, hollow natural rubber, flexible fabric, synthetic resin, leather, metal or non-metal wire, and the signal cable 130 (see FIG. 4) is routed inside.

A connecting portion 102 is provided at each end of the neck mount portion 100. Each of the pair of imaging units 110 (110R, 110L) is connected and supported by the neck mount unit 100 via each connecting unit 102. A box 120 containing an electric circuit is provided in the center of the neck mount 100. An operation switch group 36 is provided near the imaging unit 110R of the neck mount unit 100.

The wearable device 1 is capable of capturing the omnidirectional image disclosed in Patent Document 2, for example.

As shown in FIG. 2, the photographing unit 110R includes a photographing lens 10R and an image sensor 12R, and the photographing unit 110L includes a photographing lens 10L and an image sensor 12L.

In the present embodiment, as will be described below, a configuration in which two captured images captured by two sets of imaging lenses and image pickup devices are joined together to generate a single composite image (a spherical image). However, in another embodiment, a configuration may be adopted in which three or more photographed images photographed by three or more photographing lenses and image pickup elements are combined to generate a single composite image.

As shown in FIG. 2, the wearable device 1 includes an image processing unit 14, a CPU (Central Processing Unit) 16, a ROM (Read Only Memory) 18, and a RAM in addition to the taking lenses 10R and 10L and the image pickup devices 12R and 12L. A (Random Access Memory) 20, a RAM interface 22, a storage 24, a storage interface 26, a triaxial acceleration sensor 28, a battery 30, motors 32 and 34, and an operation switch group 36 are provided.

The operation switch group 36 includes various operation units necessary for the user to operate the wearable device 1, such as a power switch, a release switch, an operation dial, and operation keys. When the power switch is pressed by the user, power is supplied from the battery 30 to each part of the wearable device 1. The CPU 16 controls the wearable device 1 as a whole by accessing the ROM 18 to load the control program into the work area and executing the loaded control program.

The taking lens 10R and the taking lens 10L are fish-eye lenses (or wide-angle lenses) having the same optical performance, and have an angle of view (shooting range) exceeding 180 degrees. Hereinafter, the optical axis of the taking lens 10R will be referred to as “optical axis AXR”, and the optical axis of the taking lens 10L will be referred to as “optical axis AXL”.

The image pickup element 12R is installed at a position where the center of the image pickup surface (the center of the effective pixel area) is orthogonal to the optical axis AXR of the taking lens 10R and the image pickup surface is the image forming surface of the taking lens 10R. The image pickup element 12L is installed at a position where the center of the image pickup surface (the center of the effective pixel area) is orthogonal to the optical axis AXL of the image pickup lens 10L and the image pickup surface becomes the image forming surface of the image pickup lens 10L.

As will be described later in detail, the image capturing unit 110R and the image capturing unit 110L are connected to and supported by the neck mount unit 100 via the connecting unit 102 so as to be rotatable in two axial directions. As shown in FIG. 1, the photographing unit 110R and the photographing unit 110L are initially positioned such that the optical axis AXR of the photographing lens 10R and the optical axis AXL of the photographing lens 10L are coaxial (both in the Y-axis direction) and photographing is performed. The lens 10R and the taking lens 10L are positioned so as to face opposite directions.

The image sensor 12R and the image sensor 12L are image sensors having the same specifications (the same number of effective pixels, the same pixel size, etc.). Illustratively, the image pickup devices 12R and 12L are CMOS (Complementary Metal Oxide Semiconductor) image sensors equipped with Bayer array filters, and are connected by respective pixels on the image pickup surface via the corresponding taking lenses 10R and 12L. The imaged optical image is accumulated as electric charge according to the amount of light. The image pickup devices 12R and 12L convert the accumulated charges into a voltage (hereinafter referred to as “image signal”) by a floating diffusion amplifier. The image signals output from the image pickup devices 12R and 12L are input to the image processing unit 14. The image pickup devices 12R and 12L may be CCD (Charge Coupled Device) image sensors, or may be image sensors equipped with complementary color filters. Neck mount examination (fixed neck)

The image processing unit 14 performs predetermined signal processing on the image data input from the image pickup devices 12R and 12L. For the sake of convenience of description, the data of one captured image including the image signal of each pixel will be referred to as “image data”. For convenience of description, image data input from the image sensor 12R and processed in the image processing unit 14 is referred to as “image data DA”, and an image input from the image sensor 12L and processed in the image processing unit 14 is described. The data will be referred to as "image data DB".

The image processing unit 14 performs OB (Optical Black) correction processing, defective pixel correction processing, linear correction processing, shading correction processing, and area division averaging processing on the image data DA and DB, The image data DA and DB after the division averaging process are stored in the RAM 20 via the RAM interface 22.

Information (addresses) of defective pixels of the image pickup devices 12R and 12L detected in the inspection process at the time of manufacture is stored in the ROM 18 in advance. In the defective pixel correction process, the pixel value of the defective pixel at the address stored in the ROM 18 is corrected based on the combined signal from a plurality of adjacent pixels.

The image processing unit 14 then performs white balance processing, gamma (γ) correction processing, Bayer interpolation processing, YUV conversion processing, edge enhancement processing, and color correction processing on the image data DA and DB stored in the RAM 20. The image data DA and DB after the color correction processing are stored in the RAM 20 via the RAM interface 22.

The image processing unit 14 performs crop processing on the image data DA and DB after color correction processing stored in the RAM 20, and then performs distortion correction processing and composition processing. In the distortion correction process, distortion correction and vertical correction (tilt correction) are performed on the two image data DA and DB based on the information output from the triaxial acceleration sensor 28. In the combining process, the two pieces of image data DA and DB after the distortion correction process are combined (in other words, the two picked-up images picked up by the image pickup devices 12R and 12L are joined together), and a spherical image (stereoscopic image). The image data of the angle 4π radian is generated.

The image processing unit 14 can also separately store each of the image data DA and DB as individual image data.

The image processing unit 14 compresses the spherical image data in a predetermined format such as JPEG (Joint Photographic Experts Group). The compressed spherical image data is stored in the storage 24 via the storage interface 26. The storage 24 is, for example, a microSD card.

The spherical image data may be transferred to an external device such as a PC or a smartphone via a wireless communication such as Wi-Fi or Bluetooth (registered trademark). The user can view the captured spherical image on the screen of the external device. The connection between the wearable device 1 and the external device is not limited to the wireless connection, and may be prioritized.

The image capturing unit 110R and the image capturing unit 110L are spaced apart from each other near the user's chin in which vignetting is less likely to occur, in order to avoid the occurrence of vignetting due to the user's head. Therefore, for example, a blind spot that cannot be photographed occurs at a close distance in front of the user's head (see FIG. 8 ). The image capturing unit 110R and the image capturing unit 110L are rotatably supported by the neck mount unit 100 so as to be rotatable in two axial directions in order to eliminate such blind spots and capture a close-up image.

Specifically, the image capturing unit 110R is configured such that the roll direction (direction around the first axis AXR1 orthogonal to the optical axis AXR) and the yaw direction (orthogonal to the optical axis AXR and the first axis AXR1) with respect to the neck mount unit 100. It is rotatable about a second axis AXR2 which is orthogonal to each other. Similarly to the neck mount unit 100, the imaging unit 110L includes a second roll direction (a direction around the first axis AXL1 orthogonal to the optical axis AXL) and a yaw direction (orthogonal to the optical axis AXL and orthogonal to the first axis AXL1). It is rotatable about the axis AXL2).

By operating the switches included in the operation switch group 36, the user can arbitrarily rotate the photographing units 110R and 110L in the roll direction or the yaw direction.

FIG. 4A shows a state in which the photographing unit 110R and the photographing unit 110L are rotated by 90° in the yaw direction from the initial state shown in FIG. 1 so that the photographing lens 10R and the photographing lens 10L face the front. FIG. 4B shows the shooting range in the state shown in FIG.

As shown in FIG. 4B, when the taking lens 10R and the taking lens 10L face the front, the close range in front of the user enters the photographing range. That is, there is no blind spot at the close range in front of the user, and it is possible to shoot the close range in front of the user. As an example, the user can take photographs of food, handicrafts, and the like placed in close proximity to his/her front.

As described above, the wearable device 1 according to the present embodiment has a configuration capable of capturing a celestial sphere image while avoiding the occurrence of vignetting due to the user's head, but captures a close range in front of the user. can do.

FIG. 5A to FIG. 5C are diagrams mainly showing the configuration of the connecting portion 102 that connects the neck mount portion 100 and the imaging unit 110L. 5A to 5C, a state in which the cover member 102A (see FIG. 1) is removed is shown for the sake of convenience of showing the internal structure of the connecting portion 102. Further, FIG. 5C shows a cross-sectional view of the connecting portion 102 (a cross-sectional view taken along the line AA of FIG. 5A). The configuration of the connecting portion 102 is common to the left and right. Therefore, the detailed description of the connecting portion 102 that connects the neck mount portion 100 and the imaging unit 110R is omitted.

The connecting portion 102 includes a pedestal 102B having a substantially L shape. One end of the pedestal 102B is connected to and supported by the end of the neck mount portion 100, and is rotatable about the first axis AXR1 with respect to the neck mount portion 100 by the motor 32.

The lower end of the imaging unit 110L is connected to and supported by the other end of the pedestal 102B, and is rotatable about the second axis AXR2 with respect to the other end of the pedestal 102B by the motor 34.

The connecting portion 102 (base 102B) and the photographing unit 110L may be configured to be rotatable manually instead of being electrically driven.

The pedestal 102B is formed with a hollow portion 102Ba extending in the first axis AXR1 direction and a hollow portion 102Bb extending in the second axis AXR2 direction. The signal cable 130 drawn out from the inside of the neck mount section 100 is passed through the hollow sections 102Ba and 102Bb and is connected to the image pickup element 12L in the image pickup section 110L. As a result, the electric circuit (the image processing unit 14, the CPU 16, etc.) housed in the box 120 and the image pickup device 12L are electrically connected.

A spring member 102C is attached to the pedestal 102B (near the hollow portion 102Ba). A spring member 102D is attached to the base 102B (near the hollow portion 102Bb). Notches 102Ca and 102Da are formed in the spring members 102C and 102D, respectively.

Angle restricting members 102E and 102F formed in an annular shape (in the present embodiment, an octagonal annular cross section in the direction orthogonal to the axis) are loosely fitted in the notch portions 102Ca and 102Da, respectively. The polygonal shapes of the angle regulating members 102E and 102F are not limited to octagons, but may be other polygonal shapes.

The angle regulation member 102E is fixed to the end portion of the neck mount portion 100. When the pedestal 102B rotates about the first axis AXR1 with respect to the neck mount 100, the spring member 102C fixed to the pedestal 102B rotates with respect to the angle regulating member 102E fixed to the end of the neck mount 100. ..

5D to 5F are views showing the positional relationship between the notch portion 102Ca of the spring member 102C and the angle regulation member 102E.

The notch 102Ca of the spring member 102C has a polygonal shape corresponding to the angle restricting member 102E. Specifically, as shown in FIG. 5D, the cutout portion 102Ca includes four inner wall surfaces that come into contact with four of the eight side surfaces of the angle regulating member 102E.

When the motor 32 is driven, the spring member 102C rotates with respect to the angle regulating member 102E while the notch 102Ca is expanded by the apex portion 102Ea of the angle regulating member 102E (see FIG. 5(e)). The apex 102Ca1 of the cutout 102Ca is rotated to a position where the apex 102Ca1 reaches the next apex 102Ea (a position where the angle regulation member 102E is loosely fitted in the cutout 102Ca) (see FIG. 5(f)).

As a result, the image capturing unit 110L supported by the connecting unit 102 rotates about the first axis AXR1 by 45°, and the image capturing direction of the image capturing unit 110L changes to the direction rotated about the first axis AXR1 by 45°. As long as the motor 32 is driven, the shooting direction of the shooting unit 110L changes in 45° increments around the first axis AXR1. However, the CPU 16 controls the drive of the motor 32 in consideration of the twist of the signal cable 130 caused by the rotation of the imaging unit 110L so that the imaging unit 110L does not rotate by a preset maximum angle or more.

The angle regulation member 102F is fixed to the lower end of the imaging unit 110L. When the imaging unit 110L rotates about the second axis AXR2 with respect to the pedestal 102B, the angle regulating member 102F fixed to the imaging unit 110L rotates with respect to the spring member 102D fixed to the pedestal 102B.

The cutout portion 102Da of the spring member 102D has a polygonal shape corresponding to the angle regulating member 102F, and has the same shape as the cutout portion 102Ca of the spring member 102C. Therefore, when the motor 34 is driven, the photographing unit 110L supported by the coupling unit 102 rotates about the second axis AXR2 by 45°, and the photographing direction of the photographing unit 110L rotates about the second axis AXR2 by 45°. Change to As long as the motor 34 is driven, the shooting direction of the shooting unit 110L changes in 45° increments around the second axis AXR2. However, the CPU 16 controls the drive of the motor 34 in consideration of the twist of the signal cable 130 accompanying the rotation of the imaging unit 110L so that the imaging unit 110L does not rotate by a preset maximum angle or more.

In the present embodiment, the motor 32 is a DC motor, but in another embodiment, it may be a stepping motor. In this case, the imaging unit 110L can be rotated at a predetermined angle pitch even if there is no part such as a spring member or an angle regulation member.

By changing the photographing direction of at least one of the photographing unit 110R and the photographing unit 110L, the photographing ranges of both can be overlapped as illustrated in FIG. 4B. The wearable device 1 can take a stereo image of this overlapping portion. The wearable device 1 is information necessary for performing processing regarding a stereoscopic image in an external device such as a PC or a smartphone (for example, information necessary for generating a VR (Virtual Reality) image or performing three-dimensional image analysis). Is added to the captured image data.

In the present embodiment, as an example, a state in which the taking lens 10R and the taking lens 10L face the front (see FIG. 4B) is set as the stereo photographing mode. Information necessary for performing processing relating to a stereoscopic image is added to the captured image data in the stereo shooting mode.

The information necessary for performing the processing related to the stereoscopic image is the information about the internal localization and the external localization of the image capturing unit 110 (110R, 110L) in the stereo image capturing mode, and is stored in the storage 24 in advance. If these internal and external localizations are known, the coordinates of any point in space on the image can be calculated by an external device such as a PC or smartphone, and VR images can be generated or three-dimensional image analysis can be performed. You can go.

The internal localization of the image capturing unit 110 (110R, 110L) means, for example, the focal length of the image capturing unit 110 (110R, 110L), distortion, eccentricity, image plane tilt, and performance (number of pixels) of the image sensor 12 (12R, 12L). , Pixel size, pixel pitch, etc.). The external localization of the image capturing unit 110 (110R, 110L) includes parameters such as the three-dimensional position (X, Y, Z) and the three-dimensional inclination (ω, Φ, κ) of the image capturing unit 110 (110R, 110L). Say.

Details of the information on the internal localization and the external localization can be referred to, for example, in Japanese Patent No. 4565898. For example, as the distortion information, the distortion (D _{2 (R)} , D _{4 (R)} , D _{6 (R)} ) of the second-order component, the fourth-order component, and the sixth-order component of the image capturing unit 110R, the second-order component of the image capturing unit 110L. component, fourth-order component, the distortion of the sixth-order component _{(D 2 (L), D} 4 (L), D 6 (L)), the distortion of the asymmetric component of the imaging unit _{110R (P 1 (R),} P 2 (R ₎ ), distortion (P _{1 (L)} , P _{2 (L)} ) of the asymmetric component of the imaging unit 110L, eccentricity in the s′-axis direction and t′-axis direction from the image center of the principal point of the imaging unit 110R ( X _C(R) , Y _C(R) ), the eccentricity in the s′-axis direction and the t′-axis direction from the image center of the principal point of the imaging unit 110L (X _C(L) , Y _C(L) ). Is mentioned.

The above distortion information may be added to all captured image data in order to cause an external device to generate a VR image or perform three-dimensional image analysis, and the required accuracy of the VR image or three-dimensional image analysis. Only those appropriately selected according to the above may be added to the captured image data.

The information of the internal localization does not depend on the three-dimensional position (X, Y, Z) and the three-dimensional inclination (ω, Φ, κ) of the imaging unit 110 (110R, 110L), but the information of the external localization is the imaging unit 110. It changes depending on the three-dimensional position (X, Y, Z) and the three-dimensional inclination (ω, Φ, κ) of (110R, 110L).

The imaging units 110R and 110L respectively have eight positions around the first axis AXR1 and about the first axis AXL1 (first position of ±0° which is an initial position, about the first axis AXR1 and about +45° about the first axis AXL1). Second position, around the first axis AXR1, a third position of +90° around the first axis AXL1, around the first axis AXR1, a fourth position of +135° around the first axis AXL1, around the first axis AXR1, Fifth position of +180° around the first axis AXL1, sixth position of −45° around the first axis AXL1, sixth position of −45° around the first axis AXL1, seventh position of −90° around the first axis AXL1. The position and the inclination change around the first axis AXR1 and the eighth position of -135° around the first axis AXL1), and at the same time, the position and the inclination change around the second axis AXR2 and the second axis AXL2 (±0 which is the initial position). ° A position, around the second axis AXR2, B position +45° around the second axis AXL2, around the second axis AXR2, C position +90° around the second axis AXL2, around the second axis AXR2, D-position of +135° around the second axis AXL2, E-position of +180° around the second axis AXL2, E-position of +180° around the second axis AXL2, F-position of −45° around the second axis AXL2, and second axis AXL2. The position and the inclination change depending on the position, around the second axis AXR2, the G-position of -90° around the second axis AXL2, around the second axis AXR2, and the H-position of -135° around the second axis AXL2). That is, the position and inclination of the image capturing unit 110 (110R, 110L) change at a total of 64 (=8×8) positions. In the storage 24, these 64 types of external localization information are stored in advance.

FIG. 6 shows information on external localization of the image capturing unit 110L stored in the storage 24. The storage 24 also stores information on external localization of the image capturing unit 110R, similar to FIG.

For example, all 64 types of external localization information are added to the captured image data. In this case, the user stores the position of the image capturing unit 110 (110R, 110L) at the time of image capturing, for example, from the 64 positions added to the captured image data during three-dimensional image analysis. You will be selecting a position (correct position).

The above is a description of exemplary embodiments of the present invention. The embodiments of the present invention are not limited to those described above, and various modifications are possible within the scope of the technical idea of the present invention. For example, the contents of a combination of the embodiments exemplarily described in the specification or the obvious embodiments are appropriately included in the embodiments of the present application.

In the above-described embodiment, regarding the external localization, the wearable device 1 adds the information of all the positions of the image capturing unit 110 (110R, 110L) to the captured image data, and allows the user to select the correct position information from the information. However, in another embodiment, the wearable device 1 may be configured to add only the correct position information to the captured image data, or the wearable device 1 may add the information of all positions to the captured image data and the correct position. It may be configured to add information for specifying

FIG. 7A is a view similar to FIG. 5C and shows a cross-sectional view of a connecting portion 102z of the wearable device according to another embodiment. Encoders 104A and 104B are provided on the connecting portion 102z.

The encoder 104A includes a sensor unit (light emitting diode and phototransistor) 104Aa and a rotating disk 104Ab. The sensor unit 104Aa and the rotating disk 104Ab are attached to the spring member 102C and the angle regulating member 102E, respectively. When the spring member 102C rotates with respect to the angle regulating member 102E, the code (information indicating the angular position of the rotating disc 104Ab) formed on the rotating disc 104Ab according to the rotation is read by the sensor unit 104Aa.

The encoder 104B includes a sensor unit (light emitting diode and phototransistor) 104Ba and a rotating disk 104Bb. The sensor unit 104Ba and the rotating disk 104Bb are attached to the spring member 102D and the angle regulating member 102F, respectively. When the angle regulating member 102F rotates with respect to the spring member 102D, the sensor unit 104Ba reads a code (information indicating the angular position of the rotating disc 104Bb) formed on the rotating disc 104Bb according to the rotation.

FIG. 7B shows a table in which the position of the image capturing unit 110L and the angular positions of the rotating disks 104Ab and 104Bb are associated with each other. This table is stored in the storage 24. The storage 24 also stores the same table as in FIG. 7B for the image capturing unit 110R. The CPU 16 identifies the external orientation of the image capturing units 110L and 110R from the respective codes read by the sensor units 104Aa and 104Ba with reference to this table and the table of FIG. 6, and uses the identified external orientation as captured image data.
