[0009] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Various features shown in the following embodiments can be combined with each other. Furthermore, each feature can be an invention independently.

[0010] Each figure shows XYZ coordinate axes that define a three-dimensional Cartesian coordinate system. In the embodiment, for convenience in describing the positional relationship between the position acquisition terminal 10 and the information processing terminal 1, the Z axis is defined as the up-down direction, the Z axis direction is defined as the "upward direction," the X axis direction is defined as the "width direction," the Y axis direction is defined as the "thickness direction," and the in-plane direction of the plane formed by the X axis and the Z axis (XZ plane) is defined as the "plane direction." It should be noted that these directions are used for convenience in expressing the relative positional relationship, and since the user can tilt the position acquisition terminal 10 and the information processing terminal 1 in any direction as needed, the up-down direction is not limited to always coinciding with the vertical direction, for example.

[0011] 1. Mounting state of the position acquisition terminal 10 and configuration of the information processing terminal 1 The rear perspective view of Fig. 1 and the rear view of Fig. 2 show a state in which a position acquisition terminal 10 according to an embodiment is attached to an information processing terminal 1 (e.g., a smartphone, etc.). By attaching the position acquisition terminal 10 to the information processing terminal 1, it is possible to provide an information processing device with a position acquisition function, and a high-performance position acquisition function can be easily realized. The information processing terminal 1 is shown by dashed lines in each figure, and as an example, has a substantially rectangular parallelepiped shape in a plan view (e.g., a rectangular parallelepiped with rounded corners), and has a thin plate shape or a tile shape.

[0012] To explain a usage scenario, a user can measure the position of any target in any location (real space) using an information processing terminal 1 equipped with a position acquisition terminal 10. The information processing terminal 1 equipped with a position acquisition terminal 10 can be easily carried in one hand as a portable terminal. In the embodiment, the position acquisition terminal 10 can communicate with at least one of an artificial satellite and a base station. Details of the communication functions etc. will be explained later.

[0013] In the embodiment, the information processing terminal 1 is configured such that the information processing terminal 1, which performs functions such as calculations related to surveying, and the position acquisition terminal 10, which performs the function of acquiring position information, are separate (independent) entities. For example, a mobile terminal (e.g., a smartphone or tablet) can be used as the information processing terminal 1, and the terminal can be made more highly functional by simply connecting the position acquisition terminal 10 to the mobile terminal. This has the advantage of increasing convenience, versatility, and usability.

[0014] As shown in Fig. 3, the information processing terminal 1 of the embodiment has, as an example, the structure of a typical smartphone. The information processing terminal 1 has a front surface (hidden at the back of Fig. 3 and not shown) and a terminal back surface 2. A touch panel (not shown) is provided on the front surface of the information processing terminal 1.

[0015] The rear surface 2 of the terminal is rectangular with rounded corners and has an upper end 2a, a first side end 2b1, a second side end 2b2, and a lower end 2c. The rear surface 2 of the terminal is provided with multiple cameras 5, a LiDAR sensor 6, and an LED light 7. The multiple cameras 5 and the LiDAR sensor 6 (LiDAR scanner) are optical devices and also light-sensing devices.

[0016] More specifically, in the embodiment, as an example, a camera bump 2p is provided on the upper end 2a side of the terminal rear surface 2. The camera bump 2p is a stepped portion that is convex in the thickness direction (Y-axis direction) relative to the surrounding area within the plane of the terminal rear surface 2. As an example, a camera module or the like is housed inside the camera bump 2p. The camera bump 2p extends within the plane of the terminal rear surface 2 so as to include one corner 2p1 (corner 2p1 on the first lateral end 2b1 side) and the other corner 2p2 (corner 2p2 on the second lateral end 2b2 side) on the upper end 2a side. In the embodiment, as an example, a camera 5 and a LiDAR sensor 6 are provided on the camera bump 2p so that the information processing terminal 1 has a camera 5 at the one corner 2p1 and a LiDAR sensor 6 at the other corner 2p2. An LED light 7 is arranged above the LiDAR sensor 6. Each of the cameras 5, for example, slightly protrudes from the camera bump 2p.

[0017] In the embodiment, as an example, the connection mechanism 50 is provided in the attachment area 2d in Fig. 3. The position acquisition terminal 10 is attached to the terminal back surface 2 of the information processing terminal 1 using the connection mechanism 50, as an example.

[0018] As an example, the attached area 2d is below the camera 5 and the LiDAR sensor 6 on the surface of the terminal back surface 2. The position, size, and range of the attached area 2d may vary widely depending on the rear structure of the information processing terminal 1 (such as the positions of the camera 5 and the LiDAR sensor 6) and the size and shape of the position acquisition terminal 10. In the embodiment, as an example, the attached area 2d occupies most of the area on the lower side of the terminal back surface 2 (specifically, two-thirds of the area on the lower side of the terminal back surface 2).

[0019] 2. Configuration of each part of the position acquisition terminal 10 1 and 2, the position acquisition terminal 10 includes a main body unit 20, an antenna 30, and a connection unit 40.

[0020] 2-1. Configuration of main body 20 As shown in FIG. 1, the main body 20 is attached to the rear surface 2 of the terminal (see attachment area 2d in FIG. 3). The position acquisition terminal 10 is, for example, small enough to fit in the palm of a user's hand. This has the advantage that the user can carry the information processing terminal 1 with the position acquisition terminal 10 attached in one hand. As shown in FIG. 2, the planar dimensions of the main body 20 are, for example, the same as the outer dimensions of the information processing terminal 1 in a planar view, but are not limited thereto, and may be smaller than the information processing terminal 1 as a modified example. The thickness of the main body 20 is approximately the same as or slightly thicker than the information processing terminal 1. The casing structure and internal structure of the main body 20 will be described later using FIGS. 8 and 9.

[0021] As shown in Fig. 1, the main body 20 has a pair of left and right side portions 32. As shown in Fig. 2, the main body 20 is provided with a switch 20s that performs various functions such as turning the power on and off. As an example, the switch 20s is provided on the side portion 32 of the main body 20 (specifically, the side portion located on the side of the first lateral end 2b1).

[0022] In the embodiment, as an example, each end of the main body unit 20 is rounded. Specifically, in the embodiment, as an example, the four corners are rounded in a plan view of the main body unit 20 (see FIG. 2), and the rear end (end in the Y direction) in the thickness direction of the main body unit 20 is rounded (see dashed frame E in FIG. 6). These rounded shapes have the advantage of making it easier for the user to hold the main body unit 20. Note that, as an example, in the embodiment, the rounded shape corresponding to dashed frame E in FIG. 6 is not provided on the end of the main body unit 20 on the side that comes into contact with the information processing terminal 1.

[0023] Although there is no limitation on the thickness dimension of the main body 20, in one embodiment, the thickness dimension of the main body 20 is set to a thickness that allows the information processing terminal 1 and the main body 20 to be held in one hand when attached. Specifically, for example, the thickness dimension is defined along the Y direction, and the thickness dimension of the main body 20 is set to Dk and the thickness dimension of the information processing terminal 1 is set to Di. In this case, the ratio Dk / Di is, for example, 1.5, but may also be, for example, 1.0 to 3.0, or 0.5 to 4.0, or may be, for example, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 3.0, 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, or 4.0, or may be within a range of any two of these values.

[0024] Although not shown in the drawings, the main body 20 includes a connector (e.g., USB-Type C, etc.). The connector can be provided at any position on the main body 20, but as an example, it is preferably provided on the side 32 of the main body 20 (see FIG. 1 ). The connector may be provided on either the left or right side 32, but in an example embodiment, it is provided on the right side 32. Power can be supplied to the main body 20 from an external power source (e.g., a mobile battery or an internal battery of the information processing terminal 1, etc.) via the connector. As an example, the position acquisition terminal 10 may be used while being powered (and charged). By providing the connector on the side 32, when a cable is connected to the connector on the side 32 while a surveying tool (an example of a terminal support, described later) is attached to the mounting portion 29u of the bottom 29, the cable is less likely to interfere with the surveying tool (an example of a terminal support). That is, even when a surveying tool as an example of a terminal support is attached to the attachment portion 29u of the bottom portion 29, there is an advantage that charging or communication can be performed through the connector portion arranged on the side portion 32. The connector portion may be configured to perform only one of charging and communication, or may be configured to perform both simultaneously.

[0025] 2-2.Configuration of Antenna 30 1, the antenna 30 is provided above the main body 20. As an example, the antenna 30 has a cylindrical outer shape with a diameter larger than that of the connection part 40. The antenna 30 can be any wireless communication antenna that can be used for positioning in the position acquisition terminal 10, and as an example, it may be a helical antenna.

[0026] 2-3. Configuration of the connection part 40 1 and 2, the connection unit 40 connects the main body unit 20 and the antenna 30 by extending, for example, between the camera 5 and the LiDAR sensor 6 in a plan view of the terminal rear surface 2 (see FIG. 2). This will be described in detail below.

[0027] Various configurations of the connection part 40 can be adopted, but in the embodiment, as an example, the connection part 40 is provided next to the LiDAR sensor 6, is columnar, and has a side peripheral surface. The height (i.e., length in the Z-axis direction) of the connection part 40 is slightly larger than the dimension of the camera bump 2p in the Z-axis direction (see FIG. 2). As a result, the tip of the connection part 40 protrudes above the upper end 2a of the information processing terminal 1, and the lower end part of the antenna 30 does not interfere with the information processing terminal 1.

[0028] 2, in a plan view of the rear surface 2 of the terminal, the connection part 40 extends between the camera 5 and the LiDAR sensor 6, so that the position acquisition terminal 10 can be attached without interfering with the image capturing by the camera 5 and the sensing (illumination and reception of light) by the LiDAR sensor 6. The shape and size (width and thickness) of the connection part 40 are designed so that it does not enter the angle of view of the LiDAR sensor 6 or the angle of view of the camera 5.

[0029] The rear view of Figure 2 shows the dimensions W0, W1, D1, and D2 in a plan view (see Figure 2). W0 is the width dimension of the main body 20. W1 is the width dimension (thickness or outer shape) of the connection portion 40. D1 is the dimension from one side end of the main body 20 (left side of the paper in Figure 2) to one side end of the connection portion 40 (left side of the paper in Figure 2). D2 is the dimension from the other side end of the main body 20 (right side of the paper in Figure 2) to the other side end of the connection portion 40 (right side of the paper in Figure 2). In one embodiment, D1>D2, for example.

[0030] W1, D1, and D2 are determined according to the shape, position, or size of the connection portion 40, and are preferably set appropriately according to the layout of the camera 5 and the LiDAR sensor 6 of the information processing terminal 1. While the dimensional ratios of the embodiment are described below, please note that each value is an example and is not limited to this.

[0031] W1 is determined taking into consideration, for example, the cross-sectional shape of the connection portion 40, the capacity of the internal space, mechanical strength, reliability, productivity during molding, cost, etc. The ratio W1 / W0 is, for example, 0.18, but may also be, for example, 0.10 to 0.19, or may be 0.10, 0.11, 0.12, 0.13, 0.14, 0.15, 0.16, 0.17, 0.18, or 0.19, or may be within a range of any two of these values.

[0032] D1 is determined to be a size that does not interfere with the function of the camera 5. The ratio D1 / W0 is, for example, 0.54, but may also be, for example, 0.54 to 0.60, or 0.54, 0.55, 0.56, 0.57, 0.58, 0.59, or 0.60, or may be within a range of any two of these values. However, this is just an example, and if the area occupied by the camera 5 on the rear surface 2 of the terminal is smaller, a value of, for example, 0.40 to 0.60 may be sufficient. D1 may be enlarged by reducing at least one of W1 and D2.

[0033] D2 is determined to be a size that does not interfere with the function of the LiDAR sensor 6, and in the embodiment, consideration is also given to not interfering with the function of the LED light 7. The ratio D2 / W0 is, for example, 0.27, but may be, for example, 0.26 to 0.37, or may be 0.26, 0.27, 0.28, 0.29, 0.30, 0.31, 0.32, 0.33, 0.34, 0.35, 0.36, or 0.37, or may be within a range of any two of these values. At least one of W1 and D1 may be reduced, and D2 may be increased.

[0034] 2-4. Slope 41 of connection part 40 1 to 7, in the embodiment, as an example, the side peripheral surface of the connection portion 40 includes a slope 41 on the side of the LiDAR sensor 6. As shown in FIG. 6, as an example, the slope 41 is inclined in a direction C. This direction C is a direction in which the farther away from the LiDAR sensor 6 in the direction of the irradiation optical axis yL of the LiDAR sensor 6 (see the irradiation optical axis yL in FIGS. 3 and 6), the more the slope 41 is from the LiDAR sensor 6.

[0035] The illumination optical axis yL is a reference axis set as a virtual straight line passing through the center point P of the opening of the LiDAR sensor 6 (see FIGS. 3 and 6). In the embodiment, the "direction along the illumination optical axis yL of the LiDAR sensor 6" is the same as the Y-axis direction. In each drawing, the opening of the LiDAR sensor 6 is illustrated as a dashed circle, and the opening center point P is located at the center of the dashed circle.

[0036] Although there is no limitation on the specific configuration of the LiDAR sensor 6 of the information processing terminal 1, a LiDAR sensor (LiDAR scanner) mounted on a smartphone or the like can employ, as an example, a configuration including a light source made up of multiple laser elements (e.g., a VCSEL array) and a diffractive optical element (DOE) that branches and diffuses the laser light into a predetermined pattern. Even with such a configuration, the irradiation optical axis yL can be set based on the center point of the opening of the LiDAR sensor, and the inclination angle θ of the slope 41 can be set.

[0037] In the embodiment, since the slope 41 is inclined as described above, there is an advantage that the sensing (irradiation and reception of light) of the LiDAR sensor 6 can be prevented from being hindered.

[0038] In the embodiment, the connection portion 40 is provided not only next to the LiDAR sensor 6 but also next to the camera 5. When the connection portion 40 is provided next to the camera 5, as shown in FIG. 6 , the side circumferential surface of the connection portion 40 preferably includes a slope 42 on the camera 5 side. The slope 42 slopes in a direction away from the imaging optical axis of the camera 5 as it moves away from the camera 5 in a direction along the imaging optical axis of the camera 5. Although not shown in the figure, the imaging optical axis is a reference axis set as a virtual line passing through the lens center of the camera 5 and is parallel to the illumination optical axis direction yL. By providing such a slope 42, it is possible to prevent the connection portion 40 from entering the imaging angle of view of the camera 5 and to avoid interfering with the imaging function of the camera 5. It is not essential that the connecting portion 40 further includes the inclined surface 42 described here in addition to the inclined surface 41, but it is preferable that the connecting portion 40 includes both inclined surfaces. Also, the connecting portion 40 may have the inclined surface 42 but not the inclined surface 41.

[0039] Please refer to Figures 5, 6, and 8A to 9B. In the embodiment, as an example, a connector 31 that connects to the antenna 30 is provided at the tip of the connection part 40. In the embodiment, as an example, the connector 31 is an SMA connector. As an example, the connector 31 has a screw part 31a and bolt parts 31b and 31c. As an example, the bolt parts 31b and 31c form a rectangular prism-shaped outer periphery (specifically, a regular hexagonal prism). A cable (omitted in Figure 9A) that connects the connector 31 and the circuit board 25 (see Figure 9A) can be arranged inside the connection part 40.

[0040] For example, the connection portion 40 is a rectangular prism (e.g., a regular hexagonal prism) similar in shape to the outer periphery (bolt portions 31b, 31c) of the connector 31. For example, the inclined surfaces 41 and 42 are one of a plurality of side surfaces of the rectangular prism (e.g., a regular hexagonal prism).

[0041] The embodiment is merely an example, and the connecting portion 40 is not limited to a hollow regular hexagonal prism. Any hollow polygonal prism (e.g., a regular n-gonal prism or a non-regular n-gonal prism with n=3 or more) may be used, or a hollow prism with any cross-sectional shape may be used. For example, in the case of a quadrangular prism with a square or rectangular cross-section, by arranging one of the four corners facing the LiDAR sensor 6 in the top plan view shown in FIG. 6, a desired inclination angle θ can be imparted to one of the four side surfaces. Furthermore, the cross-section may be a trapezoidal prism, or may have a shape including a curve. In other words, a configuration in which at least a portion of the side circumferential surface of the connecting portion 40 is curved may also be used.

[0042] 2-5. Connecting mechanism 50 and connecting structure 24 An example of a connection method when attaching the position acquisition terminal 10 to the information processing terminal 1 will be described below. As shown in Fig. 4, the main body 20 has an opposing surface 23 that faces the terminal back surface 2, and this opposing surface 23 has a connecting structure 24. As an example, the connecting mechanism 50 and the connecting structure 24 are configured to be connected to each other by rotating them in the plane of the terminal back surface 2 while they are fitted together (see rotation direction A in Fig. 2 or 3).

[0043] Specifically, the connecting structure 24 has four claws 24a arranged in the circumferential direction, and connection is achieved by each of the claws 24a being locked into four engaging grooves 51 of the connecting mechanism 50. More specifically, as an example, the connecting structure disclosed in Japanese Patent No. 7681936 etc. can be adopted.

[0044] If the position acquisition terminal 10 were to rotate when the information processing terminal 1 is held in the hand, the connection portion 40 would enter the angle of view of the LiDAR or the angle of view of the camera. In this regard, in the embodiment, a stopper structure that is difficult to rotate is employed for the coupling mechanism 50 and the coupling structure 24. When the claw portion 24a and the engagement groove 51 are engaged by rotating the position acquisition terminal 10 in the rotation direction A (see FIG. 2 or FIG. 3), the position acquisition terminal 10 is integrated with the information processing terminal 1 at a predetermined position without rattle. Thereafter, the engagement will not be released unless a certain amount of force or more is applied to rotate the terminal in the opposite direction, making it possible to prevent the connection portion 40 from entering the angle of view of the LiDAR or the angle of view of the camera.

[0045] 2-6. Engagement structure for preventing rotation of main body 20 In the embodiment, as an example, the connecting mechanism 50 includes an engaging protrusion 52 (see FIG. 3) as an example of a "first engaging portion," and the connecting structure 24 includes an engaging recess 24b (see FIG. 4 or 5) as an example of a "second engaging portion." When the connecting mechanism 50 and the connecting structure 24 are connected, the first and second engaging portions (the engaging protrusion 52 and the engaging recess 24b) engage with each other so as to restrict rotation of the main body 20 within the plane of the rear surface 2 of the terminal.

[0046] 3, the engaging protrusions 52 are provided in the central region of the connecting mechanism 50. In the embodiment, for example, a plurality of (for example, four) engaging protrusions 52 are arranged at equal intervals around the center point of the connecting mechanism 50. The engaging protrusions 52 are located inside the engaging grooves 51.

[0047] 4 or 5, the engagement recesses 24b are provided in the central region of the connecting structure 24. In the embodiment, for example, a plurality of (for example, four) engagement recesses 24b are arranged at equal intervals around the center point of the connecting structure 24. The engagement recesses 24b are located more inward than the claw portions 24a.

[0048] In the embodiment, as an example, each engagement recess 24b includes a fitting portion 24b1 and a guide portion 24b2. When the coupling structure 24 and the connecting mechanism 50 are coupled, the fitting portion 24b1 and the engagement protrusion 52 are in the same position in a plan view (see FIG. 2). The fitting portion 24b1 is formed to a depth corresponding to the protruding dimension of the engagement protrusion 52 so that the fitting portion 24b1 can receive the engagement protrusion 52. The guide portion 24b2 is formed shallower than the fitting portion 24b1. The guide portion 24b2 extends a predetermined distance in an arc shape along a direction around the center point of the coupling structure 24, and one end is connected to the fitting portion 24b1. According to this configuration, when the connecting mechanism 50 and the connecting structure portion 24 are rotated in the rotation direction A (see Figure 2 or Figure 3) within the plane of the rear surface 2 of the terminal while they are engaged with each other, the engaging protrusion 52 is first guided along the guide portion 24b2 and finally fits into the engaging portion 24b1.

[0049] In the embodiment, when the engaging protrusion 52 fits into the engaging recess 24 (fitting portion 24b1), the engaging protrusion 52 gets caught in the engaging recess 24 (fitting portion 24b1) so as to restrict movement in the rotation direction A. By employing such an engaging structure (a hooking shape using protrusions and recesses in the embodiment), it is possible to prevent the position of the position acquisition terminal 10 from changing inadvertently. In the embodiment, this engaging structure (hooking shape) is employed in addition to the claw structure (claw portion 24a and engagement groove 51), which has the advantage of reliably preventing the position of the position acquisition terminal 10 from shifting.

[0050] The above configuration is merely an example. In the embodiment, multiple (four) engaging protrusions 52 are formed, but this is not limited thereto. A single engaging protrusion may be formed, or none may be formed. In the embodiment, multiple (four) engaging recesses 24b are formed, but this is not limited thereto. A single engaging recess may be formed, or none may be formed. The depth of the guide portion 24b2 may be constant, for example. Alternatively, the depth may vary so that the guide portion 24b2 forms an inclined surface. If the guide portion 24b2 is inclined, the depth may be deeper as it approaches the fitting portion 24b1. The surface of the guide portion 24b2 may be flat, but this is not limited thereto. It may be uneven or stepped. For example, a staircase-like step may be provided from one end of the guide portion 24b2 to the other end. The "engagement" in the embodiment is not limited to the structure in which a protrusion fits into a recess, as in the above example. For example, as another example, a structure in which a protrusion (first engaging portion) and another protrusion (second engaging portion) come into contact with each other to restrict rotation may be used.

[0051] 2-7. Configuration of step portion 23b As shown in FIGS. 4 to 6, in the embodiment, the main body 20 has, for example, a step portion 23b on the facing surface 23. As is clear from referring to FIG. 1 together with FIG. 4, the step portion 23b is, for example, provided above the connecting structure 24 on the facing surface 23 and directly below the camera 5 when the facing surface 23 and the terminal rear surface 2 are overlapped. The step portion 23b is lower than the other portion 23a of the facing surface 23 so as to create a gap between the facing surface 23 and the terminal rear surface 2 (see step G in FIGS. 5 and 6). The step portion 23b is a stepped portion provided so as to be recessed in the thickness direction (Y-axis direction) of the main body 20 relative to its surroundings (the other portion 23a of the facing surface 23). The step portion 23b is provided within the plane of the facing surface 23 from the periphery of the connecting structure 24 to the outer circumferential edge of the main body 20.

[0052] 4, the step portion 23b in the embodiment is provided over an angle of about ¼ of the outer periphery of the connecting structure 24. The angle α is an angle around the center point of the connecting structure 24 (i.e., the center point of rotation between the connecting structure 24 and the connecting mechanism 50) in the XZ plane. As an example, in the embodiment, the Z axis is set as the reference axis of 0 degrees, and the flat step portion 23b is provided over an entire 90 degrees from the upper end 2a side of the information processing terminal 1 toward the camera 5 side.

[0053] Step portion 23b can suppress interference with at least camera 5 when coupling structure portion 24 is rotationally fitted to couple with connecting mechanism 50. Step portion 23b can also suppress interference with camera bump 2p as well as camera 5. Interference can be suppressed by setting depth G of step portion 23b to an appropriate value (e.g., at least equal to or greater than the protruding dimension of camera 5 protruding from camera bump 2p).

[0054] 2-8.Configuration of bottom 29 See FIG. 7. In this embodiment, the main body 20 has a bottom 29. The bottom 29 has a mounting portion 29u. As an example, the mounting portion 29u is provided coaxially with (i.e., coincident with) the central axis (CL1) of the antenna 30, and is used to attach a surveying jig (e.g., a ferrule or monopod, not shown), which is an example of a terminal support. This has the advantage that the antenna 30 and the surveying jig can be aligned. As an example, the mounting portion 29u may be a screw hole.

[0055] More specifically, as an example, a ferrule may be attached to the attachment portion 29u. The ferrule has a certain length and, when attached to the attachment portion 29u, protrudes downward from the position acquisition terminal 10 (vertically downward along the Z axis). The length of the ferrule may be stored in the memory unit 8b (see FIG. 10) or may be registered in a dedicated app or the like installed in the information processing terminal 1. With the ferrule attached to the attachment portion 29u, the information processing terminal 1 with the position acquisition terminal 10 attached may be installed at a desired location to perform positioning (single-point positioning). By using the registered length of the ferrule, the user can easily measure the latitude, longitude, and altitude of the tip of the ferrule without calculating an offset value.

[0056] As another example, the mounting portion 29u may be configured to allow attachment of a monopod (a monopod with a level). A ferrule is provided at the tip of the monopod. A mobile terminal holder may also be connectable to the monopod. The length of the monopod may be registered in a dedicated app or the like installed on the information processing terminal 1. As an example, the monopod may be attached to the mounting portion 29u, the position acquisition terminal 10 may be connected to the monopod, and the information processing terminal 1 may be attached to the mobile terminal holder. Alternatively, the monopod may be placed at a desired positioning point to perform positioning (single-point positioning). By using the registered length of the monopod, the user can easily measure the latitude, longitude, and altitude of the ferrule tip of the monopod without calculating offset values. The monopod may also be configured to allow attachment of another bipod (e.g., a pole stand).

[0057] If there is a misalignment between the phase center of the antenna 30 and the center of the mounting portion 29u (screw hole), the position of the surveying jig will be misaligned, posing a problem such as the need to measure the azimuth each time and perform a correction calculation for the horizontal offset value. This is cumbersome and may increase errors. In this regard, in the embodiment, as an example, the phase center of the antenna 30 is aligned with the center of the mounting portion 29u (e.g., screw hole). Therefore, the embodiment can suppress cumbersome correction calculations and error problems. Here, we have described the use of a surveying jig as an example of a terminal support body to be attached to the mounting portion 29u, but this is not limited to a configuration dedicated to surveying, and a structure that simply has the function of supporting the position acquisition terminal 10 may also be used.

[0058] 3. Assembly structure, internal configuration and functional parts of the position acquisition terminal 10 Please refer to Figures 8A and 9A. As shown in the exploded perspective view of Figure 8A, in the position acquisition terminal 10, the main body 20 has a lid 22 and a housing 28, and the connection part 40 has a first side peripheral part 40a and a second side peripheral part 40b. The lid 22 is integral with the first side peripheral part 40a, and the housing 28 is integral with the second side peripheral part 40b. There are no limitations on the material, and any resin material may be used, for example.

[0059] In the back surface structure of the cover part 22 shown in Fig. 9A, for example, a circuit board 25 is provided on the upper side and a battery 26 is provided on the lower side. On the circuit board 25, various circuit elements (e.g., various semiconductor chips such as processors and memories, communication modules, interface circuits, etc.) for realizing each function of the position acquisition terminal 10 (e.g., information processing including storage and calculation, communication, input / output control, signal processing, etc.) are mounted. For example, the circuit board 25 includes a communication unit 25a (see Fig. 11) for communication with the information processing terminal 1, etc. As an example, the battery 26 is flat, has a size that covers almost the entire lower area of ​​the cover part 22, and is rectangular in plan view.

[0060] The inner surfaces of the first peripheral side portion 40a and the second peripheral side portion 40b form an internal space of the connection portion 40. This internal space expands into a regular hexagonal prism shape at least on the tip side of the connection portion 40 (in this embodiment, the entire length of the connection portion 40) (see FIGS. 8A, 8B, and 9A). The bolt portion 31c can be accommodated in the tip of this regular hexagonal prism-shaped internal space. This allows the bolt portion 31c to be positioned and accommodated.

[0061] 4. Functional configuration and acquisition of various location data 4-1. Internal configuration and communication connection of information processing terminal 1 The information processing terminal 1 can be any mobile terminal (e.g., any smartphone), and its specific internal configuration is not limited. As illustrated in the block diagram of FIG. 10 , the information processing terminal 1 includes, for example, a communication unit 8a, a storage unit 8b, an arithmetic processing unit 8c (a control unit, a processor, etc.), a touch panel 8d, a camera 5 (including a camera control unit), a LiDAR sensor 6 (including a LiDAR sensor control unit), and an internal communication bus 8e. The information processing terminal 1 may also include an audio input / output unit (including a speaker and a microphone) and a battery control unit. The information processing terminal 1 can perform various arithmetic processing related to basic smartphone functions or application functions, touch panel control, input / output processing, battery control processing, optical device control processing (including camera control processing, LiDAR control processing, etc.), and the like. The information processing terminal 1 may independently include a position acquisition function (e.g., a GNSS antenna and circuit, etc.), but it should be noted that the position acquisition function of the position acquisition terminal 10 has higher accuracy.

[0062] The communication unit 8a may be configured to be connected to a communication network via wireless communication means, such as any wireless LAN network communication, mobile communication such as 3G / LTE / 5G, Wi-Fi, or Bluetooth (registered trademark) communication. The communication unit 8a may also be configured to use wired communication means, such as USB, IEEE1394, Thunderbolt (registered trademark), or wired LAN network communication. In the case of wired communication means, a connector provided on the bottom 29 may constitute part of the communication unit 8a. The communication unit 8a may also be configured to use both the wired communication means and wireless communication means described above.

[0063] The arithmetic processing unit 8c is configured to execute processing and control related to information processing of the information processing terminal 1. The arithmetic processing unit 8c can be configured, for example, by a central processing unit (CPU). In the embodiment, the arithmetic processing unit 8c is an example of a processor capable of executing any program. The arithmetic processing unit 8c realizes various functions related to the information processing terminal 1, for example, by reading out any program stored in the storage unit 8b. Furthermore, information processing by software in the information processing terminal 1 is realized, for example, by processing various programs stored in the storage unit 8b by the arithmetic processing unit 8c as hardware.

[0064] The position acquisition terminal 10 can communicate with each internal component (e.g., arithmetic processing unit 8c, memory unit 8b, etc.) in the information processing terminal 1 via the communication unit 8a and internal communication bus 8e of the information processing terminal 1. There is no limitation on the form of communication connection between the position acquisition terminal 10 and the information processing terminal 1, and various wireless connections can be adopted, for example. Specifically, Bluetooth (registered trademark), Wi-Fi, etc. can be adopted. Furthermore, the connection is not limited to a wireless connection, and various wired connections (e.g., USB-TypeC, etc.) can also be adopted.

[0065] 4-2. Location data acquisition function, etc. The position acquisition terminal 10 can acquire position data with high accuracy. The position data may include, for example, latitude, longitude, and altitude, and may also include, for example, geoid height. Here, the position data is described as using a coordinate system such as latitude and longitude, but is not limited to this, and a planar Cartesian coordinate system may also be used.

[0066] Specifically, in the embodiment, as an example, the position acquisition terminal 10 acquires terminal position data. This terminal position data can be used to execute various position information processes in the information processing terminal 1, and as an example, position data of a subject captured by the camera 5 (subject position data) may be acquired, or position data of a point cloud acquired by the LiDAR sensor 6 (point cloud position data) may be acquired. By installing an application for realizing a desired function in the information processing terminal 1 in advance, various position information processing functions can be realized in cooperation with the position acquisition terminal 10.

[0067] The terminal location data can be acquired by communication with a satellite, communication with a base station, or SLAM (Simultaneous Localization and Mapping), and any combination of two or more of these three technologies may be used. In this case, RTK (Real Time Kinematic) may be adopted for communication between the location acquisition terminal 10 and the satellite.

[0068] Specifically, as an example, the position acquisition terminal 10 may communicate with an artificial satellite J (see FIG. 10) (communication method may be, for example, RTK, GNSS, CLAS, or SLAS) to acquire terminal position data. Note that GNSS is an abbreviation for Global Navigation Satellite System, CLAS is an abbreviation for Centimeter-Level Augmentation Service, and SLAS is an abbreviation for Submeter-Level Augmentation Service.

[0069] As another example, the position acquisition terminal 10 may be configured to be able to communicate with a base station K (see FIG. 10) at the surveying site, and to acquire terminal position data from this base station. In this case, the base station K is configured to be able to acquire base station coordinates corresponding to the position of the base station K. Then, the position acquisition terminal 10 can acquire the terminal position data based on the base station coordinates and distance information.

[0070] The position acquisition terminal 10 can acquire base station coordinates from the base station K. The position acquisition terminal 10 may calculate and acquire distance information by communicating with the base station K. Alternatively, the base station K may calculate and acquire distance information by communicating with the position acquisition terminal 10, and the base station K may transmit the distance information to the position acquisition terminal 10, thereby causing the position acquisition terminal 10 to acquire the distance information.

[0071] Here, the distance information is based on the distance between the base station K and the position acquisition terminal 10. This distance information may be, for example, information that represents the distance itself between the base station K and the position acquisition terminal 10. Alternatively, it may be, for example, information that indicates the "relative positional relationship between the base station K and the position acquisition terminal 10." This positional relationship can be grasped, for example, as the relative position (X, Y, Z) of the position acquisition terminal 10 with respect to the base station K.

[0072] Furthermore, when base station K acquires base station coordinates, it can adopt a communication method such as RTK, GNSS, CLAS, or SLAS.

[0073] To acquire terminal position data, for example, coordinates of inertial positioning using an inertial sensor may be employed, or coordinates using SLAM may be employed. For example, if an acceleration sensor or a gyro sensor is built into the information processing terminal 1, these sensors may be employed as the inertial sensor used for inertial positioning. SLAM may be employed using the camera 5, or SLAM using the LiDAR sensor 6. In SLAM, for example, coordinates can be acquired by combining the camera 5 or the LiDAR sensor 6 with the above-mentioned inertial sensor.

[0074] In the embodiment, as an example, the information processing terminal 1 equipped with the position acquisition terminal 10 may acquire relative position data in addition to terminal position data. The relative position data is data based on the relative positional relationship between the information processing terminal 1 equipped with the position acquisition terminal 10 and the subject. In the embodiment, as an example, the relative position data includes a relative position and a direction. In the embodiment, as an example, the information processing terminal 1 equipped with the position acquisition terminal 10 may acquire subject position data, etc., based on the terminal position data and the relative position data.

[0075] In the embodiment, as an example, the relative position data is acquired using the LiDAR sensor 6 of the information processing terminal 1. As an example, the information processing terminal 1 calculates the coordinates of each point of the point cloud obtained by the LiDAR scan based on the terminal position data, the relative position, and the orientation. As an example, the information processing terminal 1 acquires the subject position data based on the coordinates of a specific point in the point cloud. Note that the relative position data may be acquired using any distance measuring sensor, etc., without being limited to the LiDAR sensor 6.

[0076] The subject position data obtained by the various methods described above may be stored in a memory unit of the information processing terminal 1, displayed on a display screen, used in other processing, or transferred to an outside of the information processing terminal 1 via a communication unit, etc.

[0077] Various functions utilizing location information can be realized by, for example, processing the acquired location data, etc., using the arithmetic processing unit 8c, but the method for realizing this is not particularly limited. In the embodiment, as an example, the information processing terminal 1 is a smartphone. Therefore, as an example, an application program is downloaded from an external server to the information processing terminal 1, installed on the information processing terminal 1, and the arithmetic processing unit 8c executes the application program to realize various functions. However, this is not limited to this, and as another example, the program may be provided by being stored in advance on a non-transitory computer-readable recording medium. Furthermore, various functions are not limited to being realized by software, and at least a portion of them may be realized by hardware. Furthermore, in the embodiment, various information and concepts encompassing such information are handled, but these are represented by high and low signal values ​​or quantum bits as a binary bit set consisting of 0s or 1s, and communication and calculations can be performed using the above-mentioned software or hardware aspects.

[0078] 5. Variations FIG. 11 is a rear view of a position acquisition terminal 110 according to a modified example. In the example of FIG. 11, a portion of the main body 120 (the right end of the paper in FIG. 11) protrudes outward beyond the terminal back surface 2 of the information processing terminal 1. The antenna 30 is located diagonally above the upper end 2a of the information processing terminal 1 rather than directly above it, and is provided slightly diagonally upward when viewed from the main body 120. The connection portion 40 of the modified example may connect the main body 120 and the antenna 30 of the modified example by extending in the Z-axis direction (up and down direction) outside the terminal back surface 2 of the information processing terminal 1 in a plan view of the terminal back surface 2 of the information processing terminal 1 (see FIG. 2). Other structures (internal configuration, opposing surface structure, etc.) may be similar to those of the position acquisition terminal 10 (the opposing surface 23, the stepped portion 23b and the connecting structure 24, the circuit board 25, the battery 26, and the connector 31).

[0079] Regarding the dimensions in the modified example, the maximum width (W0 in FIG. 11) of the position acquisition terminal 110 is larger than that of the information processing terminal 1, and the minimum width is approximately the same as that of the information processing terminal 1. In the modified example, the width dimension W1 of the connection part 40 may be the same as that of the above embodiment, and D1 is a large width approximately the same as that of the camera bump 2p, and the dimension corresponding to D2 in FIG. 2 does not exist in the modified example in FIG. 11.

[0080] 11, the connection unit 40 is provided on the LiDAR sensor 6 side (the right side of the paper in FIG. 11) so as to extend outside the rear surface 2 of the terminal, but this is not limited to this. As yet another modification, the shape of the position acquisition terminal 110 may be reversed left to right in the paper in FIG. 11, and the connection unit 40 may be provided on the camera 5 side (the left side of the paper in FIG. 11) so as to extend outside the rear surface 2 of the terminal. In this case, it is preferable to provide a slope that slopes away from the imaging optical axis of the camera 5 on the side circumferential surface of the connection unit 40 on the camera 5 side. This allows the main body 20 and the antenna 30 to be connected without interfering with imaging by the camera 5.

[0081] In a modified example, the shape of the connecting portion 40 may be the same as that of the embodiment (a regular hexagonal prism), thereby allowing the inclined surface 42 (see FIG. 6 as well as FIG. 11) to exhibit the same effect as the inclined surface 41. That is, in the example of FIG. 11, the side peripheral surface of the connecting portion 40 includes, as an example, the inclined surface 42 on the LiDAR sensor 6 side. As an example, the inclined surface 42 is inclined in a direction away from the illumination optical axis yL of the LiDAR sensor 6 (see FIGS. 3 and 6) as it moves away from the LiDAR sensor 6. As with the inclined surface 41 in FIG. 1 etc., the configuration of FIG. 11 has the advantage that the inclined surface 42 is inclined so as not to interfere with the illumination of the LiDAR, and therefore does not interfere with the operation of the LiDAR.

[0082] Note that, although an example in which the position acquisition terminal 10 has the battery 26 has been described, the present invention is not limited to this. As a modified example, the position acquisition terminal 10 may not have the battery 26, and may be configured to receive power from another terminal (for example, the information processing terminal 1) or from an external power source.

[0083] In the embodiment, the information processing terminal 1 is a smartphone as an example, but is not limited to this. As another example, the information processing terminal 1 may be a tablet terminal.

[0084] In the embodiment, the information processing terminal 1 is described as having a touch panel in which the input unit and the display unit are integrally configured, but this is not limited thereto. The input unit that accepts user operation input and the display unit that displays images and the like may be configured separately. In this case, the input unit may be configured to accept input from, for example, an instruction unit (e.g., a button, a lever, etc.) provided on the information processing terminal 1, or may be configured to accept voice instructions (input) from a microphone. The display unit may employ various display devices, such as a liquid crystal display, an organic EL display, or a plasma display.

[0085] In the embodiment, the information processing terminal 1 is not provided with a case (e.g., a smartphone case, etc.), and the position acquisition terminal 10 is attached directly to the terminal back surface 2 of the information processing terminal 1. However, this is just one example, and the present invention is not limited to this. Any case may be attached to the information processing terminal 1, and the position acquisition terminal 10 may be attached indirectly to the terminal back surface 2 of the information processing terminal 1 via this case; specifically, for example, a connecting mechanism 50 may be attached to the back surface of this case.

[0086] In the embodiment, the connecting mechanism 50 and the connecting structure 24 are employed, but this is merely an example, and there is no limitation on the connecting method when attaching the position acquisition terminal 10 to the information processing terminal 1. Any connecting means (e.g., sliding in any direction, inserting in the thickness direction, adhesion, magnetic force, or a combination thereof) can be employed as long as it has at least enough connecting force to prevent the position acquisition terminal 10 from easily falling off due to its own weight or the like.

[0087] In the embodiment, as an example, the connection portion 40 is columnar, more specifically, a rod-like body, but is not limited thereto and any structure can be employed. For example, the connection portion 40 may be a plate-like body with a flat cross-sectional shape. Any structure can be employed that can connect the main body 20 and the antenna 30 by extending between the camera 5 and the LiDAR sensor 6 or extending outward from the LiDAR sensor 6 in a plan view of the rear surface 2 of the terminal. The cross-sectional shape of the connection portion 40 does not have to be a symmetrical shape such as a regular polygon, and any asymmetrical shape can be employed. Furthermore, the cross-sectional shape is not limited to a rectangular column, and the connection portion 40 may be a circular or elliptical column, or may be a columnar body with any cross-sectional shape combining curves and corners. If the connection portion 40 is positioned, sized, and shaped so that interference with the camera 5 or the LiDAR sensor 6 is not an issue, the slopes 41 and 42 can be omitted.

[0088] In the embodiment and modified examples, as an example, the shape of the connection portion 40 is approximately uniform in the length direction (Z-axis direction) (however, the tip portion where the connector 31 is provided has a reduced diameter). As a result, the slopes 41, 42 are provided over the entire length direction (Z-axis direction) of the connection portion 40. However, this is not limited thereto, and the connection portion 40 may have multiple portions in the length direction (e.g., first and second portions), and these multiple portions may have mutually different cross-sectional shapes. In this case, the slopes 41, 42 may only be provided at least in portions near the LiDAR sensor 6.

[0089] As another example, a modified example may be adopted in which multiple (e.g., two or three) RTK positioning measurements are performed simultaneously. For this purpose, multiple (e.g., two or three) connection units 40 (and antennas 30) may be provided. This has the advantage of being able to improve positioning accuracy through averaging, and also making it possible to obtain direction. When multiple connection units 40 are provided, they may be disposed at any location on the main body unit 20, but any number of them may be disposed at any location on each part of the main body unit 20 (e.g., the top, side, or back, etc.). It is also possible to provide multiple units overall by providing at least one unit at each of two or more parts selected from the top, side, and back of the main body unit 20.
