[First Embodiment]
Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram showing a display device 10 according to the present invention. The display device 10 includes an information processing device 100 and a head mounted display (HMD) 110. The information processing apparatus 100 and the HMD 110 are connected by wireless or wired communication. The HMD 110 is a video see-through HMD. The information processing apparatus 100 includes a CPU 101, a RAM 102, a ROM 103, an NVMEM 104, an interface 105, a device bus 106, and a communication unit 110. The CPU 101 executes a program stored in the ROM 103 using the RAM 102 as a work memory, and comprehensively controls each component to be described later via the device bus 106. Thereby, various processes described later are executed.

  The NVMEM 104 is a rewritable nonvolatile memory and serves as a secondary storage device. The CPU 101 can read data from the NVMEM 104 and write data to the NVMEM 104. The secondary storage device may be a storage device such as an optical disk drive in addition to the flash memory and HDD. The interface 105 exchanges data with devices such as an imaging unit 107, a display unit 108, an irradiation unit 109, and a communication unit 110, which will be described later. Note that the functions and processing of the information processing apparatus 100 to be described later are realized by the CPU 101 reading a program stored in the ROM 103 or the NVMEM 104 and executing this program.

  The HMD 110 includes two photographing units 107a and 107b, a display unit 108, and an irradiation unit 109. In the following description, the two photographing units 107a and 107b are referred to as photographing unit 107 as appropriate. The imaging unit 107 is a camera that captures an index. The display unit 108 is configured by a CRT, a liquid crystal screen, or the like, and can display various types of information as images or characters. The irradiation unit 109 is a device that irradiates infrared light. The sensor unit 113 is a light receiving sensor for infrared light irradiated by the irradiation unit 109, measures the time from when the infrared light is irradiated by the irradiation unit 109 to light reception, and calculates the distance based on the measured time. It is a TOF (Time Of Flight) sensor to be measured. The sensor unit 113 outputs the measured distance information to the information processing apparatus 100. For example, an active stereo sensor or any other sensor capable of acquiring a distance may be used instead of the TOF sensor. Further, light having a wavelength different from that of infrared light, such as visible light or ultraviolet light other than infrared light, may be used. In the present embodiment, the photographing unit 107, the display unit 108, the irradiation unit 109, and the sensor unit 113 are incorporated in the video see-through HMD 110, but are externally incorporated in the HMD 110. There may be. The communication unit 110 transmits / receives communication data to / from another information processing apparatus 112 connected to the network 111 through the interface 105.

  Next, FIG. 2 is a diagram schematically illustrating the HMD 110 and a space observed by a user wearing the HMD 110. User A is wearing HMD 110. The HMD 110 incorporates photographing units 107a and 107b corresponding to the left eye and the right eye, respectively. The imaging units 107 a and 107 b each capture a moving image in the real space, and capture a moving image in the real space including the observation object 200. The observation object 200 is an object to be observed, and is an object that actually exists in the real space. The images of each frame captured by the imaging units 107 a and 107 b are sequentially input to the image acquisition unit 301 of the information processing apparatus 100. The feature detection unit 302 detects a feature from the image input from the imaging unit 107, and the position / orientation calculation unit 304 calculates the position and orientation of the imaging unit 107 based on the detected feature.

  Then, the image generation unit 305 generates an image of the virtual object 210 based on the calculated position and orientation of the photographing unit 107. Then, the generated image of the virtual object 210 is combined with the image acquired by the image acquisition unit 301 while referring to the distance information acquired by the distance information acquisition unit 310, thereby generating a composite image. Further, the image generation unit 305 outputs the generated composite image to the display unit 108 of the HMD 110. As a result, a composite image in which the virtual object 210 is combined with the observation object 200 is displayed on the display unit 108. The display device displays this composite image. Here, it is assumed that the display unit of the HMD 110 is attached to the HMD 110 so as to be positioned in front of the user A wearing the HMD 110. For this reason, the composite image is displayed in front of the user A.

  FIG. 3 is a block diagram illustrating a functional configuration of the information processing apparatus 100 according to the present embodiment. The processing of each functional unit in this block is executed by the CPU 101 by reading the program stored in the ROM 103 or the NVMEM 104 onto the RAM 102.

  The image acquisition unit 301 receives each frame image (real space image) sequentially output from the imaging unit 107 and transfers the image to the feature detection unit 302 in the subsequent stage. Note that when a file of a moving image in the real space is stored in advance in the NVMEM 104, for example, and the information processing apparatus 100 uses the file, the image acquisition unit 301 reads the file and performs a feature detection unit at a later stage. Transfer processing to 302 is performed. When the feature detection unit 302 receives an image from the image acquisition unit 301, the feature detection unit 302 detects an image feature used to calculate the position and orientation of the photographing unit 107 from the image. Specifically, the feature detection unit 302 detects a predetermined index. Here, examples of the index include markers that are artificially arranged in the real space in order to specify the position of the HMD 110, and natural features such as corner points and edges that originally exist in the real space.

  The distance information acquisition unit 310 acquires distance information of an object existing in the real space measured by the sensor unit 113. The distance information may be an image format having the same resolution as the image acquired by the image acquisition unit 301, or may be a three-dimensional point group.

  The model data storage unit 303 stores three-dimensional model data of the observation object 200 and the virtual object 210 to be displayed on the HMD 110. The model data storage unit 303 is an area of the RAM 102, for example.

  The position / orientation calculation unit 304 is based on the image feature information detected by the feature detection unit 302 and the model data stored in the model data storage unit 303, and is based on a coordinate system based on the observation target object 10 (hereinafter referred to as reference coordinates). The position and orientation of the photographing unit 107 in the system) are calculated.

  The image generation unit 305 generates an image of the virtual object 210 based on the position and orientation of the photographing unit, and combines the image of the virtual object 210 on the image frame acquired by the image acquisition unit 301 with reference to the distance information. Is generated. Specifically, by referring to the distance information, when the real object exists before the virtual object 210, the virtual object 210 is not drawn, and when the real object does not exist before the virtual object 210, An image of the virtual object 210 can be drawn. This makes it possible to draw a more realistic composite image in consideration of the depth consistency between the virtual object 210 and the real space. The generated composite image is output to the display unit 108 of the HMD 110 (display control).

  The irradiation region estimation unit 306 estimates the irradiation region irradiated from the irradiation unit 109 based on the position and posture of the photographing unit 107 obtained by the position / orientation calculation unit 304. Details of the processing of the irradiation region estimation unit 306 will be described later with reference to FIG. Then, the estimated irradiation area information is transferred to the irradiation control unit 307. When communicating with another information processing apparatus 112, the information is also transferred to the communication control unit 308.

  The irradiation control unit 307 is based on the information on the infrared light irradiation region from the irradiation region estimation unit 306 and the irradiation information by the irradiation unit controlled by the other information processing apparatus 112 transferred from the external irradiation information acquisition unit 309. Controls the output intensity of infrared light.

  The communication control unit 308 transmits the irradiation area information acquired from the irradiation area estimation unit 306 to the other information processing apparatus 112 via the network 111. In addition, the infrared irradiation information received from the other information processing apparatus 112 is received and transferred to the external irradiation information acquisition unit 309.

  The external irradiation information acquisition unit 309 records the irradiation information irradiated by the other information processing apparatus 112 received from the communication control unit 308 in the area of the RAM 102 and notifies the irradiation control unit 307 of the irradiation information.

  FIG. 4 is a flowchart showing an irradiation area estimation process performed by the irradiation area estimation unit 306.

  Information on the position and orientation calculated from the position and orientation calculation unit 304 is acquired (S401). The position and orientation information is recorded in an area of the RAM 102, and is acquired by referring to the area. Next, the current infrared light output intensity set by the irradiation control unit 307 is acquired (S402).

  Then, based on the acquired position and orientation information and infrared light output intensity, the infrared light irradiation range is estimated with reference to the reach distance table 500 of FIG. 5 (S403). FIG. 5 is a diagram illustrating an example of the reach distance. A method of obtaining the estimation range using FIG. 5 will be described later. The estimated infrared light irradiation range irradiated from the irradiation unit 109 of the own apparatus (HMD 110) is recorded in the area of the RAM 102. When the estimation is completed, the process returns to S401 and repeats these processing flows.

  FIG. 5 shows an example of the reach distance table according to the present embodiment in the form of a table.

  The reach distance table 500 is a table in which the infrared light output intensity 501 and the reach distance 502 are paired, and the reach distance value at each output intensity is recorded. The infrared light output intensity 501 is set to a value indicating the output intensity as a current value (unit: mA). In addition, the reach distance 502 is set to a value indicating the distance that infrared light can reach in meters. For example, the value is stored in the form of a pair of intensity and distance in such a form that the reach distance is 3.5 (m) when the infrared light output intensity is 200 (mA). The reach distance table 500 is stored in advance in the NVMEM 104 or the like. By referring to this table, the distance that infrared light can reach can be estimated. Although a table is used in the present embodiment, the relationship between the output intensity and the reach distance may be obtained using a function formula.

  FIG. 6 is a diagram schematically illustrating the irradiation range estimated by the irradiation region estimation unit 306 according to the present embodiment.

  Since the value 601 of the three-dimensional position of the imaging unit 107 is (x1, y1, z1) and the irradiation unit 109 is mounted in the vicinity of the imaging unit 107, it is assumed here that they are approximately in the same position and orientation. A three-dimensional position value 603 obtained by moving the distance of the infrared light reaching distance 602 in the orientation vector direction (3.5 m in this example) from there is (x2, y2, z2). The irradiation angle 604 of infrared light is 40 ° in this example, and the irradiation range 605 can be estimated by approximating the irradiation range as a cone.

  In the present embodiment, the other information processing apparatus 112 also estimates the infrared light irradiation range similar to the schematic diagram of FIG. 6, and the communication control unit 308 as infrared light irradiation information via the network 111. To exchange information.

  FIG. 7 is a flowchart showing the processing flow of the irradiation control unit 307 according to the present embodiment.

  First, the infrared light irradiation range irradiated from the irradiation part 109 of the own apparatus (HMD110 connected to the information processing apparatus 100) demonstrated previously in FIG. 6 is referred (S701). As already described, since the estimated irradiation range is recorded in the area of the RAM 102, the area is referred to.

  Next, the infrared light irradiation range of another device (HMD connected to another information processing device 112) is referred to (S702). Here, as already described in the description of FIG. 3, the area of the RAM 102 stored by the external irradiation information acquisition unit 309 is referred to.

  Next, it is determined whether or not the irradiation regions overlap based on the information on the infrared light irradiation range of the referred device and the infrared light irradiation range of another device (S703). Specifically, the CPU 101 renders the irradiation range of both the own device and the external device using the three-dimensional position and orientation and the shape as shown in the schematic diagram of FIG. 6 as the three-dimensional CG data. Then, a determination is made as to whether the CGs in the irradiation range overlap each other.

  Next, it is determined whether or not the overlapping state of the irradiation areas in the previous loop has changed (S704). If it is determined that the overlapping state has changed (changed from a non-overlapping state to an overlapping state, or changed from an overlapping state to a non-overlapping state), the infrared light output intensity is changed (S705). . Then, the process returns to S701 again. Specifically, the infrared light output intensity is changed by changing the intensity by one step. For example, when the state is changed from a non-overlapping state to an overlapping state, the output intensity of infrared light is decreased by one step. For example, when the state is changed from the overlapping state to the non-overlapping state, it is confirmed that the non-overlapping state has been maintained for a certain period of time, and control for returning the output intensity of the infrared light is performed.

  When changing the output intensity of infrared light, the user is notified of this. FIG. 11 shows an example of a display screen for notification when the infrared light irradiation control is changed in the present embodiment.

  When the image of the virtual object 210 is combined and displayed on the display unit 108 with the real image including the observation target object 10 as a real object, the image generation unit 305 displays a warning message 1101 along with the virtual object 210 image, The infrared light reachable distance information 1102 is superimposed to generate an image. The warning message 1101 and the infrared light reachable distance information 1102 are obtained by issuing a drawing instruction to the image generation unit 305 when the irradiation control unit 307 changes the output intensity of the infrared light or the output timing. Superimposed by the generation unit 305. As described above, it is possible to present the user 40 with the overlapping of the infrared light irradiation region and the accompanying change in the infrared light output intensity.

  On the other hand, if the region overlap state has not changed, it is confirmed whether the infrared light output intensity has been changed in the previous loop (S706). If the infrared light output intensity is changed in the previous loop, the state still continues even if the infrared light output intensity is changed. Therefore, the process proceeds to S705 and the infrared light output intensity is further changed. On the other hand, if the infrared light output intensity has not been changed in the previous loop, the process returns to S701 without changing the infrared light output intensity.

  In the present embodiment, the description has been given with the configuration of only one external device (HMD connected to the information processing device 112), but a plurality of external devices may exist. In that case, CG drawing may be similarly performed on the infrared light irradiation regions of a plurality of external devices, and it may be determined whether the region overlaps with the infrared light irradiation region of the own device.

  As described above, the infrared light irradiation range irradiated from the irradiation unit 109 of the own device is estimated based on the position and posture information and the infrared light output intensity, and overlaps with the infrared light irradiation region of the external device. In such a case, it is possible to avoid duplication by weakening the infrared light output.

(Modification 1)
In the first embodiment, when the infrared light irradiation range overlaps, the apparatus changes the infrared light output intensity to avoid the overlap. On the other hand, in the present modification, when the infrared light irradiation range overlaps, priority control is performed as to which of the own device and the other device lowers the infrared light output intensity. The configurations of the HMD and the information processing apparatus according to this modification are the same as those in the first embodiment.

  FIG. 8 shows an example of the priority level definition table according to the present modification in the form of a table. The priority level definition table 800 is a table in which an identifier 801 and a priority level 802 are paired, and records a priority value of each device.

  As an example of the identifier 801, the HMD-A 10001 is an own device (HMD 110), and the HMD-B 20003 is an identifier of another device (an HMD connected to another information processing device 112). The device identifier is set to a unique and non-overlapping value.

  The priority level 802 is a value used for performing control by applying a rule that the lower the value is, the higher the priority is, and the lower priority level apparatus lowers the output intensity of infrared light. The priority level definition table 800 is stored in the NVMEM 104 area.

  FIG. 9 is a flowchart showing processing of the irradiation control unit 307 according to the priority level according to the present modification.

  First, the priority level of the own device in the priority level definition table 800 described with reference to FIG. 8 is referred to (S901). As already described, since it is recorded in the area of the NVMEM 104, the area is referred to. Similarly, the priority level of another device (corresponding to another information processing device 112 in this modification) is referred to (S902).

  Next, the reference priority level of the own device is compared with the priority level value of another device, and it is determined whether or not the own device has a higher priority level (S903). If it is determined that the own device has a higher priority level, the process returns to S901. On the other hand, when it is determined that the priority level of the own device is not higher (including the case where they are the same), the same processing as S701 to S704 is performed (S904), and the priority level of the own device and others It is checked whether the priority levels of the devices are the same (S905). If the priority level of the own device is the same as the priority level of the other device, the infrared light output timing changing process is executed (S906). Thereafter, the process returns to S901. The infrared light output timing changing process will be described later.

  When the priority level of the own device is lower than the priority level of other devices, the infrared light output intensity is changed (S907), and the process returns to S901. The reason why the repetitive processing is performed is to immediately reflect the changed priority level when the priority level is changed.

  With reference to FIG. 10, the infrared light output timing changing process in S <b> 906 will be described. FIG. 10 is a timing chart showing the infrared light output timing in time series.

  Two timings are shown in time series: the infrared light ON / OFF timing 1001 of the HMD of the own device and the infrared light ON / OFF timing 1002 of the other device (HMD connected to the other information processing device 112). ing.

  At the timing of time t1, the own device turns on the infrared light and the external device turns off the infrared light. At the timing of time t1 + 10, the own device turns off the infrared light, and the external device turns on the infrared light. Then, at the timing of time t1 + 20, the device turns on the infrared light and the external device turns off the infrared light. In this modification, the time division process is performed by switching the timing of alternately irradiating infrared light every 10 msec.

  When the priority levels are the same in this way, control is performed to alternately output infrared light so that infrared light does not overlap.

(Modification 2)
In 1st Embodiment and the modification 1, the case where the irradiation area of the infrared light of the own apparatus which moves mutually and another apparatus overlaps was demonstrated. In this modification, a case where the present invention is applied to a case where there is an infrared light irradiation device that is fixedly installed and cannot perform communication will be described. Specifically, in this modification, it is also possible to register an area that uses infrared light in a fixed installation in advance as an irradiation prohibited area, and to make an overlap determination with that area. An example of setting and acquiring the irradiation prohibited area will be described with reference to FIG.

  FIG. 12 is a schematic diagram illustrating the range of the irradiation prohibited area according to this modification.

  The irradiation prohibited area 1201 is defined as a rectangular parallelepiped area in which the three-dimensional position values for each vertex are set at eight locations (x5, y5, z5) to (x12, y12, z12). In this embodiment, the irradiation prohibited area is defined by a rectangular parallelepiped, but another shape such as a cone may be used. In this modification, the user 40 inputs the coordinates of each vertex of the rectangular parallelepiped in advance as an area of the irradiation prohibited area using the input means (keyboard) of the information processing apparatus 100, and the input value is stored in the area of the NVMEM 104. And the external irradiation information acquisition part 309 performs the process which acquires the area | region information of the irradiation prohibition area of NVMEM104 as an external infrared light irradiation area | region.

  As described above, although the device moves, even when a fixed infrared light irradiation device is present in the environment, it is possible to similarly determine overlap and control the infrared light output intensity.

[Second Embodiment]
In 1st Embodiment, the irradiation information of the infrared light irradiated from an external apparatus was received via communication, and the duplication with the infrared light of an own apparatus was judged. In the second embodiment, an embodiment is described in which infrared light directly irradiated from another device is detected from an infrared image acquired by a sensor unit and the irradiation intensity of the infrared light irradiated from the own device is changed. To do.

  FIG. 13 is a block diagram illustrating a functional configuration of the information processing apparatus 1000 according to the second embodiment. A detection unit 311 is added instead of the external irradiation information acquisition unit, communication control unit, and network of the first embodiment shown in FIG.

  The sensor unit 113 of the HMD 110 according to the present embodiment can acquire an infrared image representing infrared light emitted from another device. Then, the detection unit 311 detects whether the infrared light emitted from another device is directly reflected in the infrared image. When the detection unit 311 detects that the infrared light from the external device is directly reflected in the photographing unit, the irradiation control unit 307 changes the output intensity of the infrared light, and the red of the own device to the other device. Suppress the influence of external light. The detection unit 311 performs processing for detecting a point (or circle) region having a strong infrared brightness in the infrared image, and writes the detection result in the region of the RAM 102.

  FIG. 14 is a flowchart illustrating the processing flow of the irradiation control unit of the irradiation control unit 307 according to the second embodiment. First, the detection result of the detection unit 311 is acquired (S1401). Obtained by referring to the area of the RAM 102 written by the detection unit 311 described above.

  Next, it is confirmed whether the detection state has changed (S1402).

  When the detection state changes (changes from the undetected state to the detected state, or changes from the detected state to the undetected state), the infrared light output intensity is changed (S1403). And it returns to the process which acquires the detection result in the detection part 311 (S1401), and repeats a process. If there is no change in state, the process returns to the process of acquiring the detection result in the detection unit 311 (S1401) and the process is repeated.

  In this way, the detection unit 311 detects infrared light emitted from the external device from the captured infrared image, the irradiation control unit 307 changes the infrared light output intensity, and the device itself to another device is detected. The effect of infrared light can be suppressed.
