[0021] Hereinafter, a display system and a display program according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. First, [I] the basic concept of the embodiment will be described, then [II] specific details of the embodiment will be described, and finally, [III] modifications to the embodiment will be described. However, the present invention is not limited to the embodiment.

[0022] [I] Basic Concept of the Embodiment First, a basic concept of the embodiment will be described. The embodiment generally relates to a display system and a display program.

[0023] Here, the term "display system" refers to a concept that includes a system that identifies the irradiation position of the irradiation light irradiated onto an object and projects an irradiation graphic image, which is an image of a graphic related to the irradiation light, at a position on the object corresponding to the irradiation position, and is a concept that includes, for example, a system for supporting a specified task.

[0024] The term "target object" refers to an object onto which the irradiation light is irradiated, and is a concept that includes, for example, walls, floors, ceilings, or building components under construction or already constructed that are the subject of construction work, the inner surface of a tunnel that is the subject of civil engineering work, ships or airplanes that are the subject of manufacturing work, and any other object.

[0025] "Irradiation light" refers to light that is irradiated onto an object, and specifically, the concept includes light emitted from an irradiation light output device installed at a predetermined position around the object. "Irradiation light" is a concept that includes light that is irradiated onto an object in a point shape, light that is irradiated onto an object in a linear shape, and light that is irradiated onto an object in any other shape.

[0026] The term "irradiation position" is a concept that indicates the position where irradiation light is irradiated.

[0027] An "illumination graphic image" is an image of a graphic projected at a position corresponding to the illumination position on an object, and is an image of a graphic related to the illumination light irradiated onto the object. Note that the "image of a graphic related to the illumination light irradiated onto the object" is a concept that refers to an image of a graphic indicating the position of the illumination light irradiated onto the object, and an image of a graphic derived based on the illumination light irradiated onto the object or the position of the illumination light.

[0028] The "illumination pattern image" is a concept that indicates, for example, an image having the same shape as the shape of the illumination light irradiated onto the object (for example, an image of a point shape when the shape of the illumination light irradiated onto the object is a point shape, or an image of a line shape when the shape of the illumination light irradiated onto the object is a line shape), and an image based on the illumination light irradiated onto the object (for example, an image of a line segment formed by connecting the positions where the illumination light is irradiated onto the object or the loci of the positions when multiple illumination lights are irradiated onto the object). Note that the "when multiple illumination lights are irradiated onto the object" here is a concept that includes multiple illumination lights being irradiated at the same time, and illumination lights being irradiated one point at a time onto different positions at different times, so that illumination lights are irradiated onto different positions sequentially.

[0029] Furthermore, "an image based on the irradiated light irradiated onto an object" may be construed as including, for example, a concept including an image of a predetermined shape based on the irradiated light irradiated onto an object. As an example, if the predetermined shape is defined as a circular dot with a predetermined diameter (for example, about several mm), and the irradiated light irradiated onto the object is an elliptical or oval dot, an image of a circular dot with a predetermined diameter based on the center of gravity (i.e., the center) of the elliptical or oval shape of the irradiated light would be considered an "irradiated graphic image."

[0030] The "position corresponding to the irradiation position on the object" is a concept that includes, for example, the irradiation position itself, and a position based on the irradiation position (including a position away from the irradiation position).

[0031] The term "figure" is a concept that includes, for example, a single point, multiple points, a single line, multiple lines, and a set of these.

[0032] The "predetermined work" is work that is supported using the display system, and is a concept that includes, for example, construction work, civil engineering work, manufacturing work, and any other work.

[0033] In each of the embodiments described below, an example will be given in which the display system is used to assist in marking work, which is an example of construction work, when the "object" is a wall of a building under construction and the "irradiated light" is light that is irradiated in a point shape onto the object.

[0034] [II] Specific details of the embodiment Next, specific details of the embodiment will be described.

[0035] (composition) First, FIG. 1 is a block diagram showing a functional concept of a support system according to this embodiment, FIG. 2 is a diagram showing an example of the installation of each device included in the support system, and FIG. 3 is an explanatory diagram of the support system.

[0036] In the following description, the X-Y-Z directions shown in each drawing are directions that are orthogonal to one another, and more specifically, the Z direction is the vertical direction (perpendicular direction), and the X and Y directions are horizontal directions that are orthogonal to the vertical direction, and for example, the Z direction will be referred to as the height direction, the +Z direction as the upper side (flat surface), and the -Z direction as the lower side (bottom surface). Also, in Figure 3, for convenience of explanation, each element is illustrated schematically.

[0037] The support system 100 is a system that supports marking work in construction work, and includes, for example, the laser marking device 1 and the support device 2 shown in FIGS.

[0038] (Configuration - Laser marking device) The laser marking device 1 is an irradiation light output device installed at a predetermined position around the target wall 91, and specifically, is a device that emits (i.e., outputs) irradiation light L1. The laser marking device 1 is installed on a floor 92 as shown in Figure 2, for example, and stands on its own.

[0039] Only an outline will be explained, as the configuration of a known laser marking device can be applied as the laser marking device 1. As shown in Figure 1, the laser marking device 1 comprises, for example, a communication unit 11, an irradiation unit 12, a recording unit 13, and a control unit 14.

[0040] (Configuration - Laser marking device - Communication unit) 1 is a communication means for communicating with other devices, and is configured to include, for example, a communication circuit.

[0041] (Configuration - Laser marking device - Irradiation unit) 1 is an irradiation means that outputs and irradiates irradiation light L1. The irradiation unit 12 is configured to include, for example, a light source that outputs light of an arbitrary wavelength as the irradiation light L1 (for example, a light emitting diode (LED) or a known light source that outputs laser light). The irradiation unit 12 outputs, for example, green laser light, which is visible light.

[0042] (Configuration - Laser marking device - Recording unit) The recording unit 13 in Fig. 1 is a recording means for recording programs and various data required for the operation of the laser marking device 1, and is configured using, for example, a flash memory (not shown). However, any recording medium such as a hard disk can be used instead of or in addition to the flash memory (the same applies to the configuration of the recording unit of other devices).

[0043] (Configuration - Laser marking device - Control unit) The control unit 14 in Fig. 1 is a control means for controlling the laser marking device 1, and is specifically a computer comprising a CPU, various programs interpreted and executed on the CPU (including basic control programs such as an OS, and application programs that are launched on the OS and realize specific functions), and an internal memory such as RAM for storing programs and various data (the same applies to the configuration of the control unit of other devices). In particular, the program according to the embodiment is installed in the laser marking device 1 via any recording medium or network, thereby substantially configuring each part of the control unit 14 (the same applies to the configuration of the control unit of other devices).

[0044] (Configuration - support equipment) The support device 2 is the above-mentioned display system, and is installed, for example, on the floor 92 as shown in Fig. 2. The installation position of the support device 2 is arbitrary, and for example, it may be installed on a stand installed on the floor 92, or it may be installed on a wall or ceiling away from the wall 91 using a predetermined mounting fixture.

[0045] The support device 2 is, for example, a device separate from the laser marking device 1, and includes a communication unit 21, an image output unit 22, a photographing unit 23, a recording unit 24, and a control unit 25, as shown in FIG.

[0046] (Configuration - Support equipment - Communication department) The communication unit 21 in FIG. 1 is a communication means for communicating with other devices.

[0047] (Configuration - Support Device - Image Output Unit) The image output unit 22 in Fig. 1 is an image output means that projects and displays various images (for example, an irradiated pattern image and a reference image) onto a target object, that is, a wall 91. This image output unit 22 may have the configuration of a known so-called projector device, for example, and as one example, is configured to include a light emitting diode as a light source, an optional optical unit, etc.

[0048] (Configuration - Support Equipment - Photography Unit) 1 is a photographing means for photographing a target object, that is, a wall 91, and photographs, for example, illumination light L1 irradiated onto the wall 91 and a reference image G10. This photographing unit 23 may have the configuration of a known so-called digital camera, for example, and is configured to include an image sensor, an arbitrary optical unit, and the like.

[0049] (Configuration - Support Device - Recording Unit) The recording unit 24 in FIG. 1 is a recording means for recording programs and various data required for the operation of the support device 2, and is configured using, for example, a flash memory (not shown).

[0050] (Configuration - Support Device - Control Unit) The control unit 25 in FIG. 1 is a control means for controlling the support device 2, and functionally includes, for example, a position identification unit 251, an irradiation pattern image projection unit 252, and a reference image projection unit 253. The position identification unit 251 is a position identification unit that identifies the irradiation position of irradiation light emitted from an irradiation light output device installed at a predetermined position around the object and irradiated onto the object. The irradiation pattern image projection unit 252 is an irradiation pattern image projection unit that projects an irradiation pattern image, which is a pattern related to the irradiation light, onto a position on the object corresponding to the irradiation position based on the identification result of the position identification unit. The reference image projection unit 253 is a reference image projection unit that projects a reference image, which serves as a reference for identifying the irradiation position, onto the object. Note that the processing performed by each unit of the control unit 25 will be described later.

[0051] (process) Next, the assistance process executed by the assistance system 100 according to this embodiment will be described.

[0052] Fig. 4 is a flowchart of the support process (in the following explanation of each process, steps are abbreviated as "S") Figs. 5 to 11 are diagrams showing examples of the installation of each device included in the support system.

[0053] The support process is a process for supporting a task, and is, for example, a process executed by the support device 2.

[0054] This support process begins when, for example, the power of the support device 2 is turned on and a predetermined operation (such as pressing a start button not shown) is performed, and the explanation will begin from the point at which the process begins.

[0055] Here, for example, a case will be described in which support is provided for marking work to mark a line (marking line) that serves as a reference for construction work on a wall 91, which is the object in Fig. 5. Also, as shown in Fig. 5, a case will be described in which, for example, a worker (i.e., a user) installs and fixes the laser marking device 1 and the support device 2 at a position a predetermined distance (for example, about several meters) away from the wall 91. In this case, the laser marking device 1 and the support device 2 are directed toward the wall 91.

[0056] ===SA1=== 4, the reference image projection unit 253 projects the reference image G10 of FIG.

[0057] The "reference image" G11 is an image that serves as a reference for identifying the irradiation position of the irradiation light L11 (FIG. 7) that is irradiated onto the target wall 91. The specific configuration of this "reference image" G11 is arbitrary, but in this embodiment, for example, it is a rectangular image that includes the entire area to which the marking lines are added, and is a plain image of a color (e.g., black) that makes the irradiation light L11 that is irradiated onto the wall 91 stand out. In other words, the rectangular portion of the dashed dotted line shown as the reference image G10 in FIG. 6 etc. that is projected onto the wall 91 is displayed in plain black.

[0058] Specifically, regarding the processing of SA1 in Fig. 4, as shown in Fig. 6 etc., a reference image G10 is output and projected from the image output unit 22 onto the wall 91. In detail, for example, based on a plan for marking work, the support device 2 may be configured in advance so that the reference image G10 is projected onto an area on the wall 91 that is sufficiently larger than the area on which the marking lines are to be added, and such a reference image G10 may be projected.

[0059] Alternatively, as a variation, marking position information (e.g., a group of coordinate information, etc.) based on a predetermined position of the building under construction (e.g., a position corresponding to the upper left point on wall 91 where wall 91, the wall on the left side of the drawing in FIG. 6 adjacent to wall 91, and the ceiling intersect) is recorded in the recording unit 13 of the laser marking device 1 as information indicating the position where the marking line is to be placed. The support device 2 may then communicate with the laser marking device 1, acquire the marking position information, identify the position where the marking line is to be placed based on the acquired marking position information, and then automatically determine the projection position, size, shape, etc. of the reference image G10 based on the predetermined position, based on the image capture results from the image capture unit 23, and project the reference image G10 corresponding to the determined result.

[0060] Thereafter, the control unit 25 repeatedly performs the processes of SA2 and SA3 in FIG. 4 until a predetermined operation for ending the process (for example, an operation of pressing an end button (not shown)) is performed.

[0061] ===SA2=== In SA2 of Fig. 4, the position specifying unit 251 specifies the irradiation position. Specifically, for example, a case will be described in which the laser marking device 1 is configured so that marking position information (i.e., information indicating the position where a marking line is to be added) is recorded in the recording unit 13, and the laser marking device 1 is configured to automatically emit and irradiate one point at a time with irradiation light to positions corresponding to the endpoints of the marking line indicated by this marking position information (e.g., the points at both ends of a line segment). Note that the laser marking device 1 is configured to emit irradiation light to only one point at a time, that is, it is configured so that after the emission of irradiation light to the previous point has finished, the emission of irradiation light to the next point in the sequence begins.

[0062] Specifically, regarding the processing of SA2 in Figure 4, an image is captured of the area that captures the entire reference image G10 projected by SA1 via the photographing unit 23, and based on the photographing results of the photographing unit 23, the irradiation position of the irradiation light L11 is identified using the reference image G10 photographed by the photographing unit 23 as a reference.

[0063] 7, for example, in the case where the laser marking device 1 is irradiating a point-shaped irradiation light L11 onto a position on the wall 91 that corresponds to an area in the reference image G10, when the photographing unit 23 photographs the area corresponding to the wall 91, the reference image G10 and the irradiation light L11 irradiated into the reference image G10 will appear in the photographed image. By using predetermined positions (for example, positions corresponding to the four corners of the reference image G10) of the image showing the reference image G10 that appears in the photographed image as references, the position of the image showing the irradiation light L11 that appears in the photographed image is identified, thereby identifying the irradiation position of the irradiation light L11 in FIG. 7 that has been irradiated onto the wall 91.

[0064] Alternatively, as a variation, the laser marking device 1 may be configured to transmit information indicating the position at which the irradiation light L11 in Figure 7 is irradiated to the support device 2 based on the marking position information stored in the recording unit 13, and to identify the irradiation position of the irradiation light L11 irradiated onto the wall 91 based on the transmitted information.

[0065] ===SA3=== 4, the illumination pattern image projection unit 252 projects an illumination pattern image onto a position corresponding to the illumination position on the wall 91, based on the illumination position identified in SA2. Specifically, the illumination pattern image is output from the image output unit 22, whereby the illumination pattern image is projected onto the wall 91.

[0066] Here, for example, by outputting and projecting the irradiation pattern image G11 of Figure 8 from the image output unit 22, the irradiation pattern image G11 of Figure 8, which shows a single point shape that is the same shape as the single point-shaped light that is the irradiation light L11, is projected at the same position as the irradiation position of the irradiation light L11 of Figure 7 that is irradiated onto the wall 91 identified in SA2.

[0067] In addition, with regard to the projection pattern image projected by SA3, the support device 2 will continue to project it unless the user performs an explicit operation (for example, pressing the erase button or turning off the power of the support device 2).

[0068] In this way, for example, as shown in Figure 8, the projection pattern image G11 is projected and displayed on the wall 91, so even when the output of the projection light L11 (Figure 7) from the laser marking device 1 has ended and the projection of the projection light L11 has ceased, the user can grasp the position of the end point of the marking line by visually checking the projection pattern image G11 (Figure 8).

[0069] ===Repetitive processing=== Thereafter, as described above, the control unit 25 repeatedly performs the processes of SA2 and SA3 in FIG.

[0070] =2nd SA2= In the second SA2 of Figure 4, for example, as shown in Figure 9, when the laser marking device 1 irradiates point-shaped irradiation light L21 within the reference image G10 on the wall 91, the irradiation position of the irradiation light L21 is identified based on the reference image G10.

[0071] =2nd SA3= In the second SA3 of Figure 4, for example, as shown in Figure 10, an irradiation pattern image G21 of Figure 8 showing a single point shape having the same shape as the irradiation light L21 of Figure 9 is projected onto the same position as the irradiation position of the irradiation light L21 of Figure 9 irradiated onto the wall 91 identified in SA2.

[0072] Furthermore, in this SA3, the irradiation pattern image projection unit 252 additionally projects a linear corresponding irradiation pattern image G31 (an image showing a line segment of the marking line) corresponding to the line segment connecting the irradiation pattern image G11 (i.e., for example, an image showing the end point of the marking line) projected in the previous SA3 and the irradiation pattern image G21 (i.e., for example, an image showing the end point of the marking line) projected in the current SA3, as shown in Figure 11, for example.

[0073] In addition, when point-shaped irradiation pattern images are projected on the front and back of the support device 2, for example, control condition information for automatically projecting additional images, such as projecting additional linear irradiation pattern images corresponding to the line segments connecting these irradiation pattern images, is stored in the recording unit 24, and the support device 2 may be configured to automatically project additional irradiation pattern images based on the control condition information.

[0074] Alternatively, when a user inputs a command to project an additional irradiation diagram image (for example, a command to project irradiation diagram image G31 based on irradiation diagram image G11 and irradiation diagram image G21) to the support device 2 via an operation button not shown on the support device 2 or a remote control terminal, the support device 2 may be configured to project the additional irradiation diagram image based on the command.

[0075] In this way, for example, as shown in Figure 11, the projection pattern images G11, G21, and G31 are projected and displayed on the wall 91, so even when the output of the projection light L21 (Figure 9) from the laser marking device 1 has ended and the projection light L21 is no longer being projected, the user can grasp the position where the marking line is to be placed by visually checking the projection pattern images G11, G21, and G31.

[0076] Then, the support process ends when the user performs a predetermined operation to end the process after confirming the position based on the projection pattern images G11, G21, G31 projected and displayed on the wall 91 and then performing the work of marking the marking lines on the wall 91 using, for example, an inkwell and a marking string. Note that, when performing the work of marking the marking lines, the projection of the reference image G10 may be stopped from the viewpoint of improving workability.

[0077] (Effects of this embodiment) According to this embodiment, by projecting an irradiation pattern image at a position corresponding to the irradiation position on the object, it is possible to display, for example, the position of the irradiation light irradiated on the object using the irradiation pattern image.

[0078] [III] Modifications to the embodiment Although the embodiments of the present invention have been described above, the specific configurations and means of the present invention can be arbitrarily modified and improved within the scope of the technical ideas of each invention described in the claims.

[0079] (Number of each element in the support system) 1 and 2 of the above embodiment may include any number of elements. For example, a single laser marking device 1 (fewer than the number of support devices 2) may be provided, and multiple support devices 2 may be provided. In this case, the laser marking device 1 and a first support device 2 are used to project an irradiated graphic image onto the wall 91, and the first support device 2 maintains the projected state. Next, the laser marking device 1 and a second support device 2 (different from the first support device 2) are used to project an irradiated graphic image onto an object other than the wall 91 (e.g., the floor 92 in FIG. 2), and the second support device 2 maintains the projected state. By repeating this process, it is possible to simultaneously project an image (i.e., an irradiated graphic image) indicating the position of the marking line onto multiple locations (places corresponding to multiple directions, or different rooms, etc.) using a relatively small number of laser marking devices 1 (e.g., one).

[0080] (About the object) 12 and 13 are diagrams showing examples of the installation of each device included in the support system. In the above embodiment, the case where the wall 91 is the target object has been described, but this is not limited to this. For example, as shown in FIG. 12, both the wall 91 and the wall 93 may be the target object. In this case, in SA1 of FIG. 4, the reference image G10A is projected onto both the wall 91 and the wall 93, in SA2, the irradiation position of the irradiation light L31 irradiated onto the wall 93 is identified, and in SA3, an irradiation pattern image (not shown) showing a single point shape is projected at the same position as the irradiation position of the irradiation light L31 irradiated onto the wall 93 identified in SA2.

[0081] 13, for example, a building component 81 provided on a floor 92 may be the target object. In this case, in SA1 of Fig. 4, a reference image G10B is projected onto the building component 81, in SA2, the irradiation position of the irradiation light L32 irradiated onto the building component 81 is identified, and in SA3, an irradiation pattern image (not shown) representing a single point shape is projected onto the same position as the irradiation position of the irradiation light L32 irradiated onto the building component 81 identified in SA2.

[0082] 13, the reference image projection unit 253 may be configured to capture an image of the building component 81 via the imaging unit 23, determine the position, size, and shape of the reference image G10B based on the captured image, and project the determined reference image G10B. In detail, for example, the reference image projection unit 253 may recognize the building component 81 by performing known image recognition on the image of the building component 81, and then determine and project the reference image G10B whose position, size, and shape correspond to the contour of the recognized building component 81. In this case, the user may input information indicating that the target object is the building component 81 to the support device 2 in advance, and the above processing may be performed based on the input information.

[0083] (About the irradiation light) Fig. 14 is a diagram showing an example of the installation of each device included in the support system. In the above embodiment, the case where the irradiated light is in the form of a point has been described, but this is not limited to this. For example, as shown in Fig. 14, the laser marking device 1 may be configured to irradiate a wall 91 with linear irradiated light L41. In this case, in SA2 of Fig. 4, the irradiation position of the linear irradiated light L41 irradiated onto the wall 91 is identified, and in SA3, an irradiation pattern image (not shown) showing a single line shape (a line shape with the same length as the irradiated light L41) is projected onto the same position as the irradiation position of the irradiated light L41 irradiated onto the wall 91 identified in SA2.

[0084] (About the reference image) Also, in the above embodiment, the case where the reference image is projected in SA1 of FIG. 4 has been described. However, the present invention is not limited to this, and the processing of SA1 may be omitted, and the processing corresponding to SA2 and SA3 may be performed without projecting the reference image.

[0085] (Regarding integration) Also, in the above embodiment, the case where the laser marking device 1 and the support device 2 in FIGS. 1 and 2 are configured as separate bodies has been described. However, the present invention is not limited to this, and they may be integrated into one device including the functions of each device.

[0086] (Regarding the interpretation of the display system) Also, in the above embodiment, the case where the support device 2 is interpreted as corresponding to the "display system" has been described. However, the present invention is not limited to this. For example, in addition to the support device 2, the laser marking device 1 may also be interpreted as a component of the "display system", that is, the laser marking device 1 and the support device 2 may be interpreted as corresponding to the "display system".

[0087] (Regarding other features) Also, for example, it may be configured such that a command is input to the support device 2 based on the operation light (light for operation) irradiated into the reference image G10 in FIG. 11. For example, the case where the user uses a portable device such as a laser pointer carried by himself / herself to irradiate the reference image G10 with operation light of a color different from the color of the irradiation light from the laser marking device 1 (for example, red) to operate the support device 2 will be described. For example, the control unit 25 of the support device 2 is configured to capture a moving image of the reference image G10 via the imaging unit 23, and when red operation light appears in the moving image, the control unit 25 may be configured to perform erasure or re-display of the irradiation graphic image according to the display mode (for example, display position, blinking speed, etc.) of the operation light.

[0088] (Regarding the laser marking device) Furthermore, in the above embodiment, the case where the irradiation unit 12 of the laser marking device 1 in Fig. 1 emits visible light has been described, but this is not limiting. For example, the irradiation unit 12 may be configured to emit invisible light (i.e., infrared light or ultraviolet light). In this configuration, it is possible to visualize the invisible light using the support device 2. Note that in this configuration, for example, the position of the irradiated light, which is invisible light, may be identified based on marking position information (e.g., a group of coordinate information, etc.) from the laser marking device 1, or it may be identified based on the image capture results of an infrared camera or ultraviolet camera provided in the support device 2.

[0089] (Regarding the shape of the irradiation pattern image) Furthermore, as described above, the "illumination pattern image" may be configured to have a predetermined shape based on the illumination light irradiated onto the object. For example, if the laser marking device 1 is configured to output a circular laser beam with a predetermined diameter, when the laser beam is irradiated from a direction perpendicular to the wall 91 (FIG. 2), which is the object, the shape of the illumination light irradiated onto the object will be circular. On the other hand, when the laser beam is irradiated from an oblique direction that is not perpendicular to the wall 91 (for example, an oblique direction at an angle other than 90 degrees (e.g., 60 degrees to 75 degrees) with respect to the plane portion of the object), the shape of the illumination light irradiated onto the wall 91 will be elliptical or oval. In both of these cases, the support device 2 identifies the center of the illumination light irradiated onto the wall 91, and displays and retains a circular image with a predetermined diameter centered on the identified center as the illumination pattern image. In other words, in both cases where the shape of the irradiated light onto the wall 91 is circular and where it is other than circular (here, for example, elliptical or oblong), a circular image of a predetermined diameter can be left as the irradiated pattern image, thereby improving the visibility of the irradiated pattern image.

[0090] (About combinations) Furthermore, the techniques described in the embodiments and the techniques described in the modifications may be combined in any manner. [Explanation of symbols]
