(First embodiment)
First, with reference to FIG. 1, the outline of the display system of this embodiment will be described. FIG. 1 is a diagram illustrating an overview of a display system according to the first embodiment. As shown in FIG. 1, the display system 1 may be used while being hand-held by a user. For example, the display system 1 is a smartphone equipped with an attachment.

Here, the display system 1 arranges an AR object in an image of a building or the like that actually exists and displays it on the display unit 14 . In this embodiment, node objects and line objects are arranged as AR objects.

A node object is a virtual object that imitates a pipe part such as a joint that joins a water pipe or the like. A line object is an object that imitates pipes and lines such as water pipes and electric wires.

The display system 1 supports planning of piping and wiring by displaying node objects and line objects.

(Configuration of the first embodiment)
The configuration of the display system 1 will be described with reference to FIG. FIG. 2 is a diagram showing a configuration example of the display system according to the first embodiment. As shown in FIG. 2 , the display system 1 has an information processing device 10 and a distance measuring device 20 . The information processing device 10 and the distance measuring device 20 are communicably connected by wire or wirelessly.

For example, the distance measuring device 20 is an attachment having a detachable mechanism from the information processing device 10 . The distance measuring device 20 may include a communication module compatible with a predetermined communication standard, and communicate with the information processing device 10 using the communication module. At this time, the distance measuring device 20 can perform data communication with a wide range of devices by using widely spread communication standards such as WiFi (registered trademark) and Bluetooth (registered trademark).

The distance measuring device 20 may be equipped with a battery independent of the information processing device 10 . Further, the distance measuring device 20 may receive power from the information processing device 10 through a wired cable.

A distance measuring device 20 measures the distance to a predetermined surface. At this time, the distance measuring device 20 measures the distance by a distance measuring sensor using a laser. Here, the laser has high directivity and rectilinearity, and can measure a long distance (for example, 5 m to 50 m) compared to a sensor using infrared rays. For example, the wavelength of the laser used by the distance measuring device 20 may be equal to or greater than the wavelength of visible light and less than the wavelength of infrared light (for example, approximately 600 nm). Also, the distance measuring device 20 can measure the distance to a point in the same direction as the camera provided in the information processing device 10 . Also, the distance measuring device 20 transmits the measured distance to the information processing device 10 .

The information processing device 10 has an AR function. For example, according to the information processing device 10, an AR object can be placed at a specified location within an image captured by a camera. Here, since the information processing apparatus 10 can obtain an accurate distance to the surface, it becomes possible to arrange the AR object in close contact with the surface. For example, an AR object may be a thin or thin sheet-like object that functions like a sticky note attached to a predetermined surface in real space.

Furthermore, the information processing apparatus 10 can superimpose and display an AR object on an image captured by a camera. At that time, the information processing apparatus 10 can further display the distance to the surface numerically.

As shown in FIG. 2 , the information processing device 10 has a communication section 11 , a camera 12 , an input section 13 , a display section 14 , a positioning section 15 , a storage section 16 and a control section 17 .

The communication unit 11 performs wired or wireless data communication with another device via a network. For example, the communication unit 11 is a NIC (Network Interface Card). Camera 12 captures an image. Camera 12 captures an image of an area containing a predetermined point in space. Camera 12 is a camera. The input unit 13 receives input of data from the user. The input unit 13 is, for example, an input device such as a mouse or keyboard. The display unit 14 is a display device such as a display that displays a screen. Note that the input unit 13 and the display unit 14 may be touch panel displays.

Here, the display unit 14 displays the distance based on the distance information transmitted from the distance measuring device 20 . Also, the display unit 14 displays the distance calculated by the calculation unit 174 . The distance measuring device 20 may transmit the measured distance itself to the information processing device 10 , or may transmit a measured value such as the time required to calculate the distance to the information processing device 10 .

The positioning unit 15 identifies the position of the information processing device 10 in space. The positioning unit 15 uses, for example, infrared rays, wireless LAN (Local Area Network) beacon signals, or GNSS (Global Navigation Satellite System) such as GPS (Global Positioning System) and QZSS (Quasi-Zenith Satellite System) to determine the position. identification.

The storage unit 16 is a storage device such as a HDD (Hard Disk Drive), SSD (Solid State Drive), optical disk, RAM (Random Access Memory), flash memory, NVSRAM (Non Volatile Static Random Access Memory). The storage unit 16 stores an OS (Operating System) and programs executed by the information processing apparatus 10 . Further, the storage unit 16 stores various information used in executing the program. For example, the storage unit 16 stores AR information 161 and object information 162 .

The control unit 17 controls the information processing device 10 . The control unit 17 is a CPU (Central Processing Unit), MPU (Micro Processing Unit), ASIC (Application Specific Integrated Circuit), FPGA (Field Programmable Gate Array), or the like. For example, the control unit 17 functions as an identification unit 171 , an arrangement unit 172 , an image processing unit 173 , a calculation unit 174 and a generation unit 175 .

The specifying unit 171 can specify the relative position of the information processing device 10 when the position of the AR marker is set as the origin. Also, the AR marker is assumed to be stored in the storage unit 16 as the AR information 161 .

The placement unit 172 places the AR object with reference to reference points included in the area captured by the camera 12 . Also, the reference point is a point to be measured by the distance measuring device 20 .

In this embodiment, node objects and line objects are arranged as AR objects. First, the arranging unit 172 arranges a plurality of nodal objects in the photographed area in the space. Then, the placement unit 172 places line objects that connect the node objects.

A node object is an object that imitates a piping part or the like. A line object is an object imitating a water pipe, an electric wire, or the like.

The image processing unit 173 generates various images to be displayed on the display unit 14 . For example, the image processing unit 173 generates an image by superimposing a numerical value representing the distance measured by the distance measuring device 20 and a numerical value calculated by the calculation unit 174, which will be described later, on the image captured by the camera 12. The image processing unit 173 also acquires information about the arranged AR object from the object information 162 and generates an image in which the AR object is superimposed on the image captured by the camera 12 .

Here, the calculation unit 174 calculates physical properties of line objects that can be arranged to connect the node objects arranged by the arrangement unit 172 .

Here, physical properties are set for node objects and line objects. Physical properties include length, thickness, stiffness, and the like. For example, the calculation unit 174 can calculate the length of a line object for connecting the node objects from the distance between the node objects.

The generation unit 175 generates line objects that connect the node objects such that the physical properties calculated by the calculation unit 174 are satisfied. For example, when length is calculated as a physical property by the calculator 174, a line object having the calculated length is generated.

Then, the display unit 14 displays an image obtained by arranging the node object and the line object on the image obtained by photographing the space based on the calculation result of the calculation unit 174 . The display unit 14 can also display an image in which the node object and the line object generated by the generation unit 175 are arranged.

As shown in FIG. 2 , the distance measuring device 20 has a communication section 21 , a control section 22 and a distance measuring sensor 23 . For example, the communication unit 21 is a wireless communication module for performing data communication with the information processing device 10 . Also, the control unit 22 controls each unit of the distance measuring device 20 . For example, the control unit 22 controls the timing at which the distance measurement sensor 23 measures the distance.

A ranging sensor 23 obtains information about the distance from the camera 12 to a reference point using a laser. The ranging sensor 23 has a light projecting section 231 and a light receiving section 232 . The distance measuring sensor 23 uses a laser to measure the distance by a phase difference detection method, a TOF (Time of Flight) method, or the like.

Here, the structure of the distance measuring device 20 will be described. The distance measuring device 20 has a fastener that detachably fastens the distance measuring device 20 to the information processing device 10 . At least a portion of the fastener is adjustable in length and position.

FIG. 3 is an example of a front view of a distance measuring device attached to an information processing device. As shown in FIG. 3, the rangefinder 20 has a base 20a. The base portion 20a is provided with a holding portion 20b, a positioning portion 20c, a positioning portion 20d, and a holding portion 20e as fasteners. Further, the base portion 20a is provided with a substrate portion 22a that accommodates substrates functioning as the communication portion 21 and the control portion 22. As shown in FIG. For example, the board is a microcomputer. The light projecting section 231 and the light receiving section 232 have a lens barrel containing a light projecting element or a light receiving element and a lens.

The holding portion 20b and the positioning portion 20c are screwed into grooves provided in the base portion 20a. By loosening the screws and sliding the grooves, the holding portion 20b and the positioning portion 20c can be positioned according to the size and shape of the information processing device 10 to be mounted. and length can be adjusted. Also, it is arranged so as not to block the camera 12 of the information processing device 10 .

FIG. 4 is an example of a perspective view of a distance measuring device attached to an information processing device. As shown in FIG. 4, the holding part 20b holds the information processing apparatus 10 so as to sandwich the end of the information processing apparatus 10 with the U-shaped portion. Further, the holding portion 20e has the same shape as the holding portion 20b. Further, the positioning portion 20c and the positioning portion 20d are L-shaped and fix the information processing apparatus 10 so as not to move in the horizontal direction.

Here, the direction from the holding portion 20e to the holding portion 20b is the upward direction, the direction from the holding portion 20b to the holding portion 20e is the downward direction, the direction from the positioning portion 20c to the positioning portion 20d is the right direction, and positioning is performed from the positioning portion 20d. Let the direction toward the portion 20c be the left direction.

As shown in FIG. 4 , the length of the lens barrels of the light projecting section 231 and the light receiving section 232 is at least twice the thickness of the information processing apparatus 10 . Thus, in order to improve the effective distance and accuracy of distance measurement using a laser, it is necessary to increase the size of the entire distance measurement sensor 23 including the lens barrel. Moreover, it is practically difficult to incorporate the enlarged distance measuring sensor 23 into a smartphone or the like that is generally used. Therefore, as in the present embodiment, by providing the large distance measuring sensor 23 in the distance measuring device 20 detachable from a smartphone or the like, distance measurement using a laser can be performed easily and with high accuracy. .

Also, when the distance measuring device 20 is attached to the information processing device 10, which is a smart phone, the touch panel display is positioned in the area surrounded by the fasteners. Moreover, each fastener is arranged so as not to interfere with the touch panel display, terminals, buttons, and the like of the information processing apparatus 10 .

FIG. 5 is a diagram showing an example of a screen displayed on the display unit. As shown in FIG. 5, the display unit 14 displays a plurality of node objects including node object 51 . Furthermore, the display unit 14 displays a plurality of line objects including a line object 61 connecting each node object.

Also, as shown in FIG. 5, a setting button 141a, a distance display field 141b, a menu control button 141c, a mode selection button 141d, and an arrangement button 141e are displayed on the left side of the screen.

The setting button 141a is a button for setting a node object to be arranged. The distance display column 141b displays the output value of the distance measuring device 20. FIG. For example, the distance display field 141b displays the distance measured by the laser. The menu control button 141c is a button for switching display/non-display of the option screen on the right side. The mode selection button 141d is a button for selecting a mode.

Modes include those that change the display mode of node objects and line objects. For example, modes that change the display mode include a real display mode and a highlight display mode.

For example, when the real display mode is selected, the display unit 14 displays the node object and the line object with a texture that imitates the texture (steel material, vinyl chloride, etc.) of the actual member.

On the other hand, when the highlight display mode is selected, the display unit 14 highlights and displays the node object and the line object. For example, the display unit 14 displays the node object and the line object by filling them with a single color or by blinking them.

When the placement button 141e is operated, the placement of the node object or line object is determined.

A home button 143a, a moving distance magnification setting field 143b, an object position coordinate control panel 143c, an object rotation control panel 143d, an object drawing control panel 143e, and a sketch button 143f are displayed on the right side of the screen.

The moving distance magnification setting field 143b sets the moving distance when changing the position coordinates of each object. The object position coordinate control panel 143c accepts operations for moving the object along each of the three axes of the three-dimensional space. The object rotation control panel 143d accepts an operation to rotate an object along a predetermined axis (eg vertical axis).

The object drawing control panel 143e accepts operations related to object selection and drawing. Also, when the sketch button 143f is operated, a captured image of the currently displayed screen is acquired and saved.

As shown in FIG. 6, the placement unit 172 can place the node object and the line object at a position corresponding to the underground or a position corresponding to a blind spot of a building or the like. FIG. 6 is a diagram showing an example of a screen displayed on the display unit.

Also, as shown in FIG. 7, the placement unit 172 can place line objects in all directions including the depth direction of the space. FIG. 7 is a diagram showing an example of a screen displayed on the display unit.

(Example 1)
As shown in FIG. 8, the display unit 14 displays a list of node objects that can be arranged. The placement unit 172 places the node object selected from the list. FIG. 8 is a diagram showing an arrangement example of node objects.

Here, it is assumed that each node object imitates a piping part, and the joining positions of line objects are determined in advance. For example, the joint positions of the node object "Tee" are left, right, and bottom. Also, for example, the joint positions of the node object "elbow" are up and right. It should be noted that each node object is assumed to be rotatable about an arbitrary axis in the three-dimensional space.

As shown in FIG. 8, the placement unit 172 places node objects that simulate piping parts with joint positions determined in advance. Then, the calculation unit 174 calculates the physical properties of the line object that can be arranged with the end point joined to the joining position of the node object.

The arranging unit 172 corrects the positions of the node objects adjacent to the node objects "Tee" and "Elbow" to 90 degrees according to the joining position.

(Example 2)
It is assumed that the line object has a curvature defined as the degree of bendability. The calculation unit 174 calculates the degree of bending of the line objects when the line objects are arranged so as to connect the node objects.

Then, as shown in FIG. 9, the display unit 14 displays whether or not the predetermined linear member can withstand bending that satisfies the degree of bending calculated by the calculation unit 174 . FIG. 9 is a diagram showing a display example of line objects.

For example, in the state shown on the left side of FIG. 9, the curvature of the line object 611 connecting the node object 511, the node object 512, the node object 513, and the node object 514 exceeds a predetermined curvature.

In this case, the display unit 14 displays the line object 611 in a predetermined style. In the example of FIG. 9, the display unit 14 displays the line object 611 as a one-dot chain line. Also, the display unit 14 may change the color of the line object 611 .

In the state shown on the right side of FIG. 9, the position of the node object 512 has been changed. Thereby, the curvature of the line object 611 is less than the preset curvature. At this time, the display unit 14 changes the style of the line object 611 from the dashed-dotted line to the solid line for display.

(Example 3)
The placement unit 172 can place the node object at a position a predetermined distance away from an object existing in space.

10 and 11 are diagrams for explaining the offset from the object. As shown in FIG. 10, the placement unit 172 moves the placed node object 521 to a position away from the wall by a predesignated pipe offset value (for example, 5 cm) (node object 522).

Also, as shown in FIG. 11, the position of the nodal object 522 after movement may be defined by rotating the offset direction.

(Example 4)
The calculator 174 measures the distance between each object. 12 and 13 are diagrams for explaining distance measurement.

As shown in FIG. 12, the calculator 174 can calculate the distance between the node object 531 and the straight line object 631 . The calculator 174 can also calculate the distance between the node object 531 and the closest point on the curved line object 632 .

As shown in FIG. 13, the calculator 174 can calculate the horizontal distance and the vertical distance between the nodal object 542 and the nodal object 541 .

Also, the calculation unit 174 can calculate the distance in consideration of the pipe diameter and clearance. In the example of FIG. 13, the distance between a circle 741 centered at the node object 542 or the circle 742 and the node object 541 is calculated.

(Example 5)
The placement unit 172 places the node object at a position a predetermined distance away from the virtual plane defined in the space. FIG. 14 is a diagram explaining the offset from the definition plane.

In the example of FIG. 14, the defining plane 751 is defined by a node object 551 , a node object 552 and a node object 553 . A node object 554 , a node object 555 , a node object 556 and a node object 557 are arranged at positions separated from the definition plane 751 by a constant distance.

FIG. 15 is a diagram for explaining detection of interference. The calculation unit 174 detects that the line object 661 placed between the node object 561 and the node object 562 interferes with another object.

FIG. 16 is a diagram for explaining the arrangement of line objects. When the line object 671 placed between the node object 571 and the node object 572 interferes with another object, the generator 175 generates a line object 672 that can avoid the interference.

Note that the positioning result of step S101 may be used as auxiliary information when specifying the AR marker.

The rangefinder 20 measures the distance (step S205). Then, the information processing device 10 displays the distance measured by the distance measuring device 20 in the image (step S206). If the information processing apparatus 10 does not receive an operation to place an AR object (step S207, No), the information processing apparatus 10 ends the process.
