Description

  The present invention relates to a surveying instrument that measures physical quantities by applying solid coordinate measurement.

  There has been a demand for measuring various physical quantities in various businesses and DIY (Do It Yourself). Examples of the physical quantity include length, angle, area, volume, horizontality, azimuth angle, coordinate value, two-dimensional shape data, and three-dimensional shape data.

  As tools for measuring these physical quantities, there are object differences, rulers, curved measures, tape measures, laser distance meters, etc. for measuring lengths, protractors, triangle rulers, transit etc. for measuring angles, horizontal, Examples of measuring the vertical include a level and swinging down, and examples of measuring the azimuth include an azimuth magnetic needle and a gyrocompass.

  In particular, for measuring the length, a metal tape measure or a laser distance meter having a bowl-shaped cross section is widely used.

Japanese Examined Patent Publication No. 38-022984 Japanese Patent Application Laid-Open No. 08-094322

  However, the tools described above are specialized in measuring specific physical quantities. Taking the case of measuring the length with a tape measure as an example, it is easy to measure the distance between two specific points and read it as a numerical value. It is difficult to execute a single tape measure when finding a point 1 m directly above. In these cases, in addition to the tape measure, it is necessary to combine a compass and a downward swing, but the operation of using a plurality of tools at the same time is extremely complicated.

  There are many other cases like this, and there is a problem that tools specialized for a specific application are highly convenient only for that application and are not considered to be used in combination with other tools. (Multi-tool simultaneous use problem).

  Similarly, taking a tape measure as an example, when measuring the distance between two specific points, if the distance exceeds the direct reach of a human hand, the origin of the tape measure is set to one of the two points. An operation of pulling the tape measure to the other point after fixing to the point is necessary. Normally, although the tape measure origin is equipped with parts to assist fixing, it is not universal and often requires some kind of setup to fix the origin. And after measuring the length, the origin of the tape measure that had been fixed must be released. For this reason, two steps of fixing and releasing the origin are required.

  Furthermore, since the measurer himself / herself who wants to measure the distance must make at least one reciprocation between the two points, if the distance between the two points becomes large, the man-hours required to move the measurer cannot be ignored.

  As described above, there is also a problem that there are man-hours that cannot be ignored, such as setup other than measurement work and movement of the measurer (preparation problem outside measurement work).

  In addition, if the area of a triangle formed by three specific points is taken as an example, the area of the triangle can be obtained by calculation if the length of the three sides is known. The operations of measuring the length with a tape measure, etc., “recording the measured length”, and “calculating based on the recorded length of three sides” are required. At this time, there is a possibility that the measurer may make a mistake for each of “when measuring”, “when recording”, and “when calculating”, and the measurer has appropriate skills to prevent inaccurate results. Required.

  Because of this background, there was a problem that it was necessary to consider the skill of the measurer (measurer skill problem).

  The present invention has been made under such a background, and an object of the present invention is to provide a surveying apparatus that can measure a physical quantity based on a measurement point by a simple method.

  Therefore, the present invention has been made to solve the above problems.

FIG. 10 is a diagram illustrating an aspect of an exemplary embodiment of the present invention in Example 2. 6 is a cross-sectional view illustrating an embodiment of the present invention in Example 2. FIG. It is sectional drawing showing the other aspect (ball-point pen) of embodiment of this invention in Example 2. FIG. It is sectional drawing showing the other aspect (mechanical pen) of embodiment of this invention in Example 2. FIG.

  Prior to specific description as an example, the basic principle of the embodiment of the present invention will be described.

  In the embodiment of the present invention, the physical quantity to be measured and the type of the physical quantity are determined, the coordinate values of a plurality of “points” required according to the type of the physical quantity to be measured are respectively measured, and the measured coordinates This is realized by calculating a physical quantity based on the value.

  In the embodiment of the present invention, a “point” at which coordinate values are measured in order to calculate a physical quantity is defined as a “measurement point”. For example, when measuring the length between two points, each of the two points is a measurement point. Similarly, when measuring the area of a triangle, each of the three vertices of the triangle is a measurement point.

  The basic principle of the embodiment of the present invention is that “measurement point coordinate value measurement” “measured coordinate value storage” “physical quantity calculation based on stored coordinate value”.

  In the embodiment of the present invention, the measurement of coordinate values includes both a relative method and an absolute method. As a relative method, a method of measuring a coordinate value in a virtual three-dimensional coordinate with electromagnetic waves or ultrasonic waves and a method of integrating the measured values of an acceleration sensor can be applied. is there. As an absolute method, a method of measuring coordinate values as longitude / latitude altitude information of the earth by a method using GPS, Loran, or a mobile phone base station radio wave is applicable. In addition, by combining a direction sensor, a gravity sensor, and the like, the virtual three-dimensional coordinate system can be converted into the longitude and latitude altitudes of the earth, so that guidance information described later can be expressed by directions and altitudes.

  In addition, the user can arbitrarily set the coordinate system used in the measurement of the coordinate values according to the embodiment of the present invention. For example, if you want to place a desk indoors with reference to a specific wall or column, it is better to set the coordinate system based on the plane of the wall and measure the coordinate value than to detect the correct orientation and vertical. This is because it is efficient.

  There are three modes in the embodiment of the present invention, which are “fixed measurement point physical quantity calculation mode”, “variable final measurement point physical quantity calculation mode”, and “variable final measurement point guidance mode”, respectively.

  The fixed measurement point physical quantity calculation mode is a mode in which all measurement points are determined in advance and the physical quantity is calculated based on the coordinate values of those measurement points. For example, it corresponds to the case of measuring the length between two specific points or the case of measuring the area based on the vertices of a triangle.

  The variable final measurement point physical quantity calculation mode is determined by excluding the last one (physical quantity determination measurement point) from the types of desired physical quantity and the measurement points necessary to calculate the physical quantity. The coordinate value of the current measurement point is regarded as the current measurement point coordinate value, assuming that the point specified by the point specification means of the device (current measurement point) is the last one of the necessary measurement points (physical quantity determination measurement point). In this mode, a physical quantity is measured based on the current measurement point coordinate value and the coordinate value stored in the point coordinate value storage means, and output to the information output means.

  In this mode, coordinate value measurement and physical quantity calculation at the current measurement point are continuously performed at regular time intervals, the latest physical quantity is always output to the information output means, and the user outputs the physical quantity to the information output means. The point where the desired physical quantity can be obtained can be found by arbitrarily moving the current measurement point while confirming the above. For example, this is the case when searching for a point 10 m away from a certain point.

  The variable final measurement point guidance mode is similar to the variable final measurement point physical quantity calculation mode, but the final physical point (desired physical quantity), its type, and the last one of the measurement points required to calculate the desired physical quantity ( If the physical quantity is determined except for the physical quantity determination measurement point), the physical quantity is calculated by considering the current measurement point as the physical quantity determination measurement point (current measurement point physical quantity), and the desired physical quantity is compared with the current measurement point physical quantity. This is a mode for outputting to the information output means how much the current measurement point is moved in which direction and how much it reaches the point where the desired physical quantity is obtained (guidance information).

  In this mode, coordinate value measurement and physical quantity calculation at the current measurement point are performed continuously at regular time intervals, the latest guidance information is always output to the information output means, and the user is output to the information output means While confirming the guidance information, the current measurement point can be arbitrarily moved to find a point where a desired physical quantity can be obtained. For example, when searching for a point 10 m away from a certain point, a physical quantity of 10 m is input to the surveying device in advance, and the corresponding point is searched according to the guidance of the surveying device.

  The result (comparison information) of comparing the current measurement point physical quantity with the desired physical quantity may be output instead of the guidance information. Since the user can know the difference between the current measurement point and the point where the desired physical quantity can be obtained from the comparison information, there are obstacles (walls, grooves, etc.) between the current measurement point and the point where the desired physical quantity can be obtained. In this case, it is easy to take measures based on the difference.

  Hereinafter, a surveying apparatus according to an embodiment of the present invention (hereinafter referred to as the present surveying apparatus) will be described with reference to the drawings.

  FIG. 1 is a diagram showing a concept of a surveying apparatus according to an embodiment of the present invention. The entire surveying apparatus 11 includes a point coordinate value measuring unit 12, a point specifying unit 13, a point coordinate value storing unit 14, an information output unit 15, and an instruction input unit 16 that are controlled by the control unit 18.

  The control means 18 corresponds to an embedded computer composed of a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), and the like. The point designating means 13 is for indicating the point where the user of the surveying instrument wants to obtain coordinate values.

  The point coordinate value measuring means 12 is for measuring the coordinate value of the point designated by the point designating means 13. In the embodiment of the present invention, the measurement principle of the coordinate value is not specified. Any function that can obtain coordinate values in an arbitrary three-dimensional coordinate system is applicable.

  The point coordinate value storage unit 14 stores the coordinate values of the points measured by the point coordinate value measurement unit 12 and is mainly intended to store the measurement point coordinate values, but is not limited thereto. The point coordinate value storage means 14 corresponds to a flash memory, an HDD (Hard Disc Drive), a battery backup RAM, or the like. It can also be part of the control means 18.

  The information output means 15 transmits information to the user. Applicable to liquid crystal displays or speakers.

  The instruction input means 16 receives an instruction from the user. A switch, a touch panel, or a microphone is applicable.

  FIG. 2 is substantially the same as FIG. 1, but the desired physical quantity storage means 17 is added. The desired physical quantity storage means 17 stores a desired physical quantity that is determined in advance as a surveying condition by the user, and corresponds to a flash memory, an HDD, a battery backup RAM, or the like. The desired physical quantity storage unit 17 can be a part of the control unit 18 as in the example shown in FIG.

Example 1
In the first embodiment, the operations of the fixed measurement point physical quantity calculation mode, the variable final measurement point physical quantity calculation mode, and the variable final measurement point guidance mode will be described based on FIGS. 3, 4, and 5.

(Fixed measurement point physical quantity calculation mode)
This mode corresponds to the case where all measurement points are determined in advance. That is, the user wants to obtain the physical quantity as a numerical value. Hereinafter, an example in which the user measures the area of a triangle formed by three points A, B, and C will be described.

  The user first turns on the surveying instrument. At this time, initialization is performed. Thereafter, the user instructs the surveying apparatus to “calculate the triangular area based on the three-point coordinate values”.

  Next, the user moves to the vicinity of the point A with the surveying instrument and brings the point designating means 13 into contact with the measurement point. In FIG. 3, the point designating means 13 is arranged at one corner in front of the lower surface of the surveying instrument. As shown in FIG. 4, the point designating means 13 can be pulled out to have a sharp tip. In the surveying device, a switch (not shown) detects this extraction operation, and when it is as shown in FIG. 4, the control means 18 performs control so that a sharp tip becomes a point for measuring coordinate values.

  In this way, the user gives a measurement point designation completion instruction to the surveying apparatus through the instruction input means 16. That is, the user's instruction is “Measure the coordinate value using the point currently pointed by the point designating means 13 as a measurement point”.

  Alternatively, a sensor may be provided in the point designating unit 13 as shown in FIG. This sensor detects that a pressing force of a certain level or more is applied when the point designating unit 13 contacts the measurement point, and automatically considers that the above-mentioned measurement point designation completion instruction is input. Specifying measurement points becomes easier. You may employ | adopt the mechanism in which the point designation | designated means 13 produces a moderation feeling (click feeling) at the time of a press.

  Furthermore, the coordinate value measurement by the point coordinate value measuring means 12 is continuously performed, and when the amount of change in the coordinate value within a predetermined time is equal to or less than the predetermined value, the above measurement point designation completion instruction is automatically input. It may be considered as what has been done. This makes it possible to specify the measurement point by a method in which the measurement point is held for a predetermined time while being in the state specified by the point specifying means 13, and is further simplified. In particular, when the measurement point is soft, it is preferable to prevent the measurement point from being moved or damaged by the pressing force.

  Further, as shown in FIG. 5, a laser distance meter may be used instead of the point specifying means 13. In this case, the point irradiated by the laser beam 13a becomes the measurement point, and it can be considered that the measurement point designation completion instruction is input when the laser distance meter completes the distance measurement. The control means 18 controls the distance measured by the laser distance meter to be used for the coordinate value measured by the point coordinate value measuring means 12.

  The switch for detecting the pulling operation of the point specifying means 13 may be controlled so that the laser distance meter does not operate when the sharp tip is protruding. In this way, it can be seen at a glance whether or not the laser rangefinder is operable, so that it is possible to prevent an accident in which a laser beam is accidentally radiated to surrounding people.

  In this way, coordinate value measurement is performed using the point A as the first measurement point, and this coordinate value is stored in the point coordinate value storage unit 14 as a measurement point coordinate value.

  Next, the user moves to the vicinity of the point B with the surveying instrument, and similarly measures the coordinate value with the point B as the second measuring point. As a result, the coordinate value of the point B is also stored in the point coordinate value storage unit 14 as the measurement point coordinate value.

  Further, the user moves to the vicinity of the point C with the surveying instrument, and similarly measures the coordinate value with the point C as the third measuring point. As a result, the coordinate value of the point C is also stored in the point coordinate value storage unit 14 as the measurement point coordinate value.

  When the user finishes measuring the coordinate value of the point C, the materials necessary for calculating the area of the triangle are ready, so the user here instructs the surveying device through the instruction input means 16 for a physical quantity calculation instruction. . In response to this physical quantity calculation instruction, the surveying apparatus calculates the area of the triangle based on the coordinate values of the measurement points A, B, and C stored in the point coordinate value storage unit 14 and outputs the calculated area to the information output unit 15. . The user obtains the output area, and the series of surveying work ends.

  In addition, since the instruction “triangular area calculation based on the three-point coordinate value” is given in advance, the third measurement point can be obtained even if the user does not explicitly issue a physical quantity calculation instruction to the surveying instrument. When the coordinate value of the point C is measured, the area of the triangle may be calculated and output to the information output means 15.

(Variable final measurement point physical quantity calculation mode)
This mode corresponds to the case where the measurement points are determined in advance except for the last one. That is, the user assumes a physical quantity as a numerical value to some extent and wants to determine the last measurement point while actually measuring the physical quantity. Hereinafter, an example in which the user measures the area of a triangle formed by three points A, B, and C will be described.

  The user first turns on the surveying instrument. At this time, initialization is performed. Thereafter, the user instructs the surveying apparatus to “calculate the triangular area based on the three-point coordinate values”. At this time, an instruction that “the last one point is variable” is also given.

  Next, the user moves to the vicinity of the point A with the surveying instrument, and brings the point designation means 13 into contact with the point A. As for the point designating unit 13, the description of FIGS. 3 to 5 described above is similarly applied.

  In this way, the user gives a measurement point designation completion instruction to the surveying apparatus through the instruction input means 16. As a result, coordinate value measurement is performed using the point A as the first measurement point, and this coordinate value is stored in the point coordinate value storage unit 14 as the measurement point coordinate value.

  Next, the user moves to the vicinity of the point B with the surveying instrument, and similarly measures the coordinate value with the point B as the second measuring point. As a result, the coordinate value of the point B is also stored in the point coordinate value storage unit 14 as the measurement point coordinate value.

  At this time, two measurement point coordinate values (point A and point B) of the three vertex coordinate values necessary for obtaining the area of the triangle are stored in the point coordinate value storage means 14 after the measurement is completed. Therefore, the point designation means 13 of the surveying instrument regards the point currently pointed (current measurement point) as the remaining one measurement point (physical quantity determination measurement point) and measures the coordinate value to calculate the physical quantity. (Current measurement point physical quantity) and output to the user through the information output means 15. Since the coordinate value measurement, current measurement point physical quantity calculation, and output to the user are performed continuously at regular time intervals, the user can arbitrarily position the surveying instrument while judging the current measurement point physical quantity to be output. It is possible to search for a point C where a desired physical quantity can be obtained by changing to.

(Variable final measurement point guidance mode)
This mode is similar to the variable final measurement point physical quantity calculation mode described above, but differs in that a desired physical quantity is determined in advance. This mode corresponds to a case where a desired physical quantity and measurement point are determined in advance except for the last one (physical quantity determination measurement point). That is, it is a case where the user clearly recognizes a desired physical quantity as a numerical value and wants to search for a physical quantity fixed measurement point. Hereinafter, an example in which the user measures the area of a triangle formed by three points A, B, and C will be described.

  The user first turns on the surveying instrument. At this time, initialization is performed. Thereafter, the user instructs the surveying apparatus to “calculate the triangular area based on the three-point coordinate values”. At this time, a specific numerical value of the desired physical quantity is input and stored in the desired physical quantity storage means 17 (desired physical quantity input process), and an instruction that “the last one point is variable” is also performed. In the configuration of FIG. 1, a function corresponding to the desired physical quantity storage unit 17 is included in a part of the control unit 18.

  Next, the user moves to the vicinity of the point A with the surveying instrument, and brings the point designation means 13 into contact with the point A. As for the point designating unit 13, the description of FIGS. 3 to 5 described above is similarly applied.

  In this way, the user gives a measurement point designation completion instruction to the surveying apparatus through the instruction input means 16. As a result, coordinate value measurement is performed using the point A as the first measurement point, and this coordinate value is stored in the point coordinate value storage unit 14 as the measurement point coordinate value.

  Next, the user moves to the vicinity of the point B with the surveying instrument, and similarly measures the coordinate value with the point B as the second measuring point. As a result, the coordinate value of the point B is also stored in the point coordinate value storage unit 14 as the measurement point coordinate value.

  At this time, two measurement point coordinate values (point A and point B) of the three vertex coordinate values necessary for obtaining the area of the triangle are stored in the point coordinate value storage means 14 after the measurement is completed. Therefore, the point designation means 13 of the surveying instrument regards the point currently pointed (current measurement point) as the remaining one measurement point (physical quantity determination measurement point) and measures the coordinate value to calculate the physical quantity. (Current measurement point physical quantity), the desired physical quantity stored in the desired physical quantity storage means 17 is compared with the current measurement point physical quantity, and the current measurement point physical quantity is determined as the desired physical quantity by moving the surveying apparatus in which direction and how much. Whether they match (guidance information) is output to the user through the information output means 15. The comparison result (comparison information) other than the guidance information may be output through the information output means 15.

  This "current measurement point coordinate value measurement", "current measurement point physical quantity calculation", "comparison with desired physical quantity", "guidance information to user, output of comparison information" is performed continuously at regular time intervals. The person can change the position of the surveying instrument arbitrarily while judging the guidance information and the comparison information to be output, and search for a point C at which a desired physical quantity can be obtained.

  Since the user can also know the difference between the current measurement point and the point where the desired physical quantity can be obtained from the comparison information, there are obstacles (walls, grooves, etc.) between the current measurement point and the point where the desired physical quantity can be obtained. When it exists, it becomes easy to take measures based on the difference.

  Depending on the coordinate measurement system used by the point coordinate value measuring means 12, the above-described guidance information may be indicated by a local reference. This is the case, for example, with reference to a specific building wall or pillar. In order to obtain guidance information and comparison information by this method, it is necessary to register a point (and a straight line or a plane composed of the points) as a reference of the coordinate system in the surveying instrument. In this case, the user sets the surveying apparatus to the coordinate reference designation mode through the instruction input means 16, designates the wall surface to be used as the reference by the point designation means 13, and “the point designation means 13 is currently designated. Instructing that the coordinate value of the point is designated as a coordinate reference is instructed through the instruction settlement means 16, and the surveying instrument receives the instruction, measures the coordinate value by the point coordinate value measurement means 12, and stores it in the point coordinate value storage means 14. It is stored as a coordinate reference specified coordinate value. If it is desired to use a straight line as a reference for the coordinate system, two coordinate reference designation coordinate values are designated. If a plane is desired to be used as a reference for the coordinate system, three coordinate reference designation coordinate values are designated.

  By adding azimuth detecting means (azimuth sensor), gravity direction detecting means (G sensor), etc. to this surveying instrument, it becomes possible to output more clear guidance information based on the azimuth and altitude.

(Measurement point designation method with laser distance meter)
In the above-described fixed measurement point physical quantity calculation mode, a measurement point designation method using a laser distance meter will be described using an example in which the user similarly measures the area of a triangle composed of three points A, B, and C. To do.

  The user first turns on the surveying instrument. At this time, initialization is performed. Thereafter, the user instructs the surveying apparatus to “calculate the triangular area based on the three-point coordinate values”.

  Next, the user moves to the vicinity of the point A with the surveying device, directs the laser beam receiving / emitting unit 13b to the point A, and operates a laser distance measuring switch (not shown).

  Since the laser beam 13a as visible light is emitted from the laser beam receiving and emitting unit 13b, the user is allowed to irradiate the point A with the laser beam 13a and keep this state for a certain time.

  As a result, the control means 18 measures the distance L between the laser beam receiving / emitting unit 13b and the point A, and also measures the coordinate value P of the surveying instrument 10 at this time. Thereafter, the emission of the laser beam 13a is finished.

  The control means 10 obtains the direction V of the laser beam 13a emitted from the surveying instrument 10 by the azimuth detecting means (not shown) and the gravitational direction detecting means (not shown), so that the measured coordinate value P of the surveying instrument 10 is obtained. By adding the values based on L and V described above, the coordinate value of the point A is obtained.

  In this way, since the user can designate the point A as a measurement point without directly contacting the surveying instrument 10 with the point A, there is an obstacle (such as a groove or a fence) between the user and the point A. Is preferred.

  Similarly, by designating the points B and C as measurement points, the area of the triangle formed by the points ABC can be obtained.

  In the above description, the user has moved to the vicinity of the point A, but it is also possible to specify the points A, B, and C as measurement points while remaining in one place without moving. In this case, since the user does not need to move, the surveying efficiency is greatly improved.

(Angle measurement method in fixed measurement point physical quantity calculation mode)
Similarly, in the above-described fixed measurement point physical quantity calculation mode, a method in which the user similarly measures the intersection angle (angle BAC) of the line segment AB and the line segment AC configured by three points A, B, and C will be described. To do.

  The user first turns on the surveying instrument. At this time, initialization is performed. Thereafter, the user instructs the surveying instrument to “calculate the two-segment intersection angle calculation using the three-point coordinate value”.

  Next, the user moves to the vicinity of the point A with the surveying instrument and brings the point designating means 13 into contact with the point A that is the measurement point. This point A is treated as a point constituting an angle to be measured (a point where line segments intersect).

  In this way, the user gives a measurement point designation completion instruction to the surveying apparatus through the instruction input means 16. That is, the user's instruction is “Measure the coordinate value using the point currently pointed by the point designating means 13 as a measurement point”. In addition, about the other designation | designated method of a measurement point, it is the same as that of description of the fixed measurement point physical quantity calculation mode. The measured coordinate value is stored in the point coordinate value storage unit 14 as the measurement point coordinate value of the point A. Subsequently, the coordinate values of point B and point C are similarly measured as measurement points and stored in the point coordinate value storage unit 14.

  Since the materials necessary for calculating the angle BAC are prepared when the user finishes measuring the coordinate value of the point C, the user instructs the surveying device through the instruction input means 16 here to calculate the physical quantity. To do. In response to this physical quantity calculation instruction, the surveying apparatus calculates the angle BAC based on the coordinate value of the measurement point ABC stored in the point coordinate value storage unit 14 and outputs it to the information output unit 15. The user obtains this output angle, and the series of surveying work ends.

In addition, since the instruction to “calculate the intersection angle of the two line segments based on the three-point coordinate value” has been given in advance, the last measurement can be performed even if the user does not explicitly issue a physical quantity calculation instruction to the surveying instrument. The angle BAC may be calculated and output to the information output means 15 when the coordinate value of the point C, which is a measurement point, is measured.
(Example 2)

  Example 2 is a writing instrument type surveying instrument as shown in FIGS. This form was adopted on the assumption that it would be easier to handle compared to a surveying device having a battledore-like box-type housing as shown in Example 1. Since the basic measurement operation is the same as that of the first embodiment, differences from the first embodiment will be described.

  The sharp tip of the writing instrument type surveying instrument of FIG. As shown in the sectional view of FIG. 7, the point designating means 13 is in contact with the sensor 13c inside, and is provided so that the sensor 13c reacts when the point designating means 13 is pressed in the axial direction. By adopting such a configuration, when the user designates the measurement point, it is possible to designate the measurement point by piercing it with the tip of the writing instrument, so that the efficiency of the measurement point designation work is improved. In addition, it is suitable for precise measurement work because a fine point can be specified as a measurement point. In addition, the measurement point may be specified by holding the pressed state for a certain period of time.

  The sensor 13c may detect a pressing in a direction (circumferential direction) perpendicular to the axial direction in addition to the pressing in the axial direction of the point specifying means 13. In this case, it can be specified as a measurement point by pressing the entire surveying instrument linearly in the circumferential direction while piercing the measurement point with the tip of the point specifying means 13. In this way, it is possible to prevent malfunction when a point that is not a measurement point is accidentally stabbed by the point designating unit 13. Similarly, it may be specified as a measurement point by holding the state of pressing in the circumferential direction for a certain period of time. Also, a special function may be assigned to moving the surveying instrument while repeatedly pressing or pressing within a certain time, such as double clicking or dragging a mouse button of a personal computer.

  Further, the pressing in the circumferential direction is not limited to a straight line, but may be a rotation operation so as to trace an arc. In this case, it is more preferable to provide different functions in the clockwise direction and the counterclockwise direction.

  Although the information output means 15 and the instruction input means 16 can be arranged on the surface of the writing instrument, it may be inconvenient to use because of its small surface area. You may operate by connecting with Bluetooth (registered trademark).

  The point designating means 13 having a sharp tip as described above may be a ballpoint pen or a sharp pen as shown in FIGS. When this configuration is adopted, it is possible to directly write a mark or the like at the point indicated by the point specifying means 13 when searching for the physical quantity fixed measurement point in the variable final measurement point physical quantity calculation mode or the variable final measurement point guidance mode.

  Although the physical quantity has been exemplified by the length and area in the above description, it is not limited thereto. Needless to say, the physical quantity may be a volume, a surface area, an angle, a flatness, an azimuth angle, or a coordinate value. Further, by tracing the surface of the object with the surveying instrument of the second embodiment, two-dimensional shape data and three-dimensional shape data can be measured, and a shape scanner can be obtained.

(About effect)
As described above, according to the surveying apparatuses 10 and 20, the physical quantity based on the measurement point can be measured by a simple method, and various physical quantities can be calculated based on the coordinate value of the measurement point. It is possible to provide a general-purpose surveying device that is not specialized for the purpose of measuring the physical quantity. Conventionally, measurement work that has been performed by combining a plurality of measurement tools in a complicated manner can be realized by a single surveying instrument, and convenience is remarkably improved.

  Further, the measurer only needs to move to specify the measurement point, and no movement for setup is required, and the man-hour for measurement is significantly reduced. Furthermore, although details will be described later, the number of man-hours can be further reduced depending on the method of specifying the measurement points.

  In addition, since the recording and calculation of the measurement results are performed in the surveying instrument, the possibility of making a mistake by the measurer is greatly reduced, and the accuracy of the results is improved. Moreover, since it can be used by anyone as long as the work procedure is understood, the need for special consideration for the skill of the measurer is reduced.

  Furthermore, since the measurement points are clearly indicated by the point designating means, marks can be written on the measurement points using the writing function of the point designating means. It is more suitable for use.

  As a result, it is possible to solve any one or more of the above-mentioned simultaneous use problem of multiple tools, the problem of preparation outside measurement work, and the measurer skill problem.

  The surveying instrument of the present invention that employs mass-produced parts as components can be used as an industry.
