Description

  The present invention relates to a geometric information processing system using a two-dimensional code such as a QR code.

  In general, map data is created in various forms in survey work and design work in the civil engineering field. Examples of such map data include design drawing data for roads and bridges, current state map drawing data for grasping the site, land lot number map data representing land boundaries, and the like. When creating these map data, the reference point used as the reference | standard of a position is provided, respectively. Here, the reference point is a measurement point that accurately measures the position and height on the earth's surface, and serves as a reliable reference for making maps, examining crustal and ground changes, and geodetic roles. It is a point to have. The reference point includes a triangle point, a polygon point, and a level point depending on the purpose of the surveying work. In the field work (field survey) in the survey work and the design work, the coordinate values (x, y, z coordinate values) of the reference point are obtained using GPS (Global Positioning System). We are doing on-site observation work. The reference point coordinates acquired in this way are used in local survey work, design work, etc., and contribute to the creation of various map data. Furthermore, in the conventional fieldwork, very expensive observation survey equipment called a total station is used. With such equipment, distance calculation, area calculation, angle calculation, azimuth calculation, etc. based on a reference point as a reference of position, etc. It is carried out.

Conventionally, as this type of technology, for example, there is a technology described in Patent Document 1.
JP 2002-257544 A

  Patent Document 1 discloses a survey drawing creation system such as a land parcel map that can simplify and automate the information collection method at a survey site in order to reduce the work time at the survey site. This survey drawing creation system such as a land parcel map performs boundary line surveying at a surveying site using a measuring instrument in which map information is stored in advance. The survey drawing creation system includes a step of reading map information into the measuring instrument, a step of adding coordinate data to the read map information, a step of storing the coordinate data and map information, and the stored map information on the screen of the measuring instrument. The step of displaying above, the step of confirming the planned survey target feature at the site as a closed figure on the screen of the measuring instrument, the step of storing the identification information about the closed figure, and the boundary line of the local survey target feature Marking the map information displayed on the measuring instrument with the position of the writing border pile placed on the measuring instrument, inputting the marked writing border pile information into the measuring instrument, and generating a connection with the marking of the writing border pile And execute. In addition, this survey drawing creation system stores closed figure data and a plurality of points of identification data together with map information as a survey map in a measuring instrument, and performs boundary line surveying using such a measuring instrument. At this time, in the surveying site, the survey drawing creation system determines a measurement target brush border pile from the step of displaying the survey drawing on the screen of the measuring instrument and the brush border pile displayed on the survey drawing. A step, a step of measuring the distance and angle by aligning the aim of the total station with the brushwork pile to be measured, and automatic input with reference to the identification data relating to the brushwork pile for each measured brushwork pile And a step of generating a connection each time the brush border pile is surveyed. Further, the survey drawing creation system performs these steps by using a plurality of measuring instruments, and receives data related to the brush border piles input by each measuring instrument with one device to generate a connection. In this way, the survey drawing creation system measures the distance and the angle sequentially using the total station for the writing circle pile stored in the survey map displayed on the screen of the measuring instrument at the survey site, Create a closed figure.

  However, the technique described in Patent Document 1 uses a very expensive total station, and there is room for improvement in terms of cost for data acquisition. In addition, the coordinate information of the reference point is acquired by the client terminal device on site or at the site via a network such as the Internet by storing coordinate data for each reference point in a remote database server or the like. Although it is possible, in this case, various operations such as field work are limited to the place where the network exists. In addition, the total station requires predetermined knowledge for its operation, such as installation work at its predetermined position, coordinate system setting work, target point collimation work, etc., and these operations become complicated, improving workability. There is room to do. In addition, the total station is large and lacks portability and poor mobility, so it cannot be easily used everywhere.

  Here, in recent years, a two-dimensional code has been proposed in which a conventional barcode is two-dimensionalized and its storage capacity (information amount) is dramatically increased. The one-dimensional code (bar code) that is currently popular has information only in the horizontal (transverse) direction, whereas this two-dimensional code has information in the two-dimensional direction of the horizontal direction and the vertical direction. As a result, the amount of information that can be encoded with a one-dimensional code is about 20 characters, whereas the amount of information that can be encoded with a two-dimensional code is dramatically increased to about 4,000 characters. Information of several tens to several hundred times can be handled. In addition, the type of information that can be encoded can represent various data such as kana, kanji, English characters, alphanumeric characters, binary data, etc., in the two-dimensional code. Furthermore, the two-dimensional code is a space-saving design to represent data in two dimensions, vertical and horizontal, and if the data amount is the same, only 1/10 to 1/100 space of the barcode is required. Display in space is possible. Furthermore, the two-dimensional code is not limited in the reading direction, and can be accurately read from any direction of 360 degrees such as vertical, horizontal, and diagonal. In addition, the two-dimensional code has a data restoration built-in function, and can restore and read data even if a part of the code is damaged or dirty. In addition, the two-dimensional code is extremely excellent in environmental resistance because the user (user) can freely set the ratio of automatic correction at the time of reading according to the environment. Further, the two-dimensional code is an open code (open source) that anyone can use as to the use of the code itself, and no usage fee (royalty) related to printing or reading work is required. Furthermore, since the two-dimensional code can be encrypted, it is necessary to print the information in a non-encrypted state when the information is disclosed and used in common with others, and the contents must be kept secret from others. Can be protected by encryption. In addition, the code shape of the two-dimensional code can be changed by changing the restoration rate of the error restoration function. For example, the code of 30% error restoration rate and the code of 15% error restoration rate Are completely different in shape. Therefore, use a two-dimensional code with different error recovery rate for the product and warranty card, and adopt the usage form such as judging that the warranty card is counterfeit when the same code is affixed to the product and warranty card. You can also. Various types of two-dimensional codes have been proposed. Typical examples in Japan include PDF417, data code, maxi code, QR code, and the like.

The two-dimensional code 1 encodes and stores the coordinate information of a measuring point or markers whose coordinate information is specified in advance. A survey point is a position or a point (measurement point) having unique coordinates specified by a boundary mark such as a reference point, a reference point, a boundary pile, or a reference point in surveying work or observation work. In addition, as described above, as shown above, a reference point (reference mark) that is laid or fixed on land, ground, or the like corresponding to the measurement point, a reference point (water mark) ), Boundary marks such as boundary piles or reference points. Furthermore, as the types of boundary marks as signs, there are various boundary marks such as stone piles, concrete piles, metal plate piles, plastic piles, fences, notches, wooden piles, etc., depending on their materials and shapes. Note that the notch is a boundary mark expressed by engraving grooves on the concrete foundation of a building. The two-dimensional code 1 is integrally fixed to the signs fixed to the measurement points. For example, the two-dimensional code 1 is a printed matter such as a sticker printed with a two-dimensional code. As shown in FIG. 2, the boundary mark M1 that specifies the measuring point P1 at the center intersection of the cross is partitioned by the cross. It is fixed to any one of the four square surfaces using an adhesive, an adhesive, or the like.

Specifically, the mobile terminal device 10 includes, for example, various mobile information terminals such as a mobile phone, a PDA (Personal Digital Assistance), and a mobile information terminal incorporating a two-dimensional code reader. As the terminal device in the present invention, any terminal device such as a mobile computer or a normal personal computer can be used in addition to the mobile terminal device 10, but the portability, portability, mobility, etc. From the beginning, it is preferable to use the mobile terminal device 10. The portable terminal device 10 has reading means (photographing means and conversion means) for reading the two-dimensional code 1 fixed to the signs M1 and M2 and outputting the corresponding coordinate information, and reading by the reading means.

Following the measurement mode selection process in STEP 13, when a two-dimensional code such as a QR code is read in STEP 14, the two-dimensional code (coordinate information) read in STEP 15 overlaps with an existing two-dimensional code (coordinate information). It is determined whether or not. If there is an overlap, an error message is displayed on the error display screen 17A5 in STEP16. On the other hand, if there is no overlap, the coordinate information of the station is displayed on the screen at STEP17. Next, in STEP 18, it is determined whether or not a predetermined number of two-dimensional codes have been read. This determination is made, for example, by confirming the end of reading with the user on the prompt screen 17A4. Steps 14 to 18 are repeated until a predetermined number of two-dimensional codes are read. When the reading of the predetermined number of two-dimensional codes is completed, the read two-dimensional codes (coordinate information) are stored in the storage unit 13 in STEP19. Here, it is assumed that the user does not read the number of two-dimensional codes necessary for various calculations in the measurement mode, and substitutes the coordinate information of the existing measurement points stored in the storage unit 13. Therefore, as shown in STEP 20, when the user requests to call the coordinate information of the registered stations (stored in the storage means 13), the station list screen 17 A 7 is displayed in STEP 21. Therefore, the user can select a desired station from a large number of stations displayed in a list and acquire the coordinate information. Alternatively, the user can acquire coordinate information of a desired station using the station search processing module shown in STEP 50. After the user specifies a station in STEP 22 or STEP 50, if the detailed information of the station specified by the user is requested in STEP 23, a process for selecting a station to display detailed information is executed in STEP 24. The detailed information of the station is displayed on the screen.

  As shown in FIG. 8, when the station reading process or the calling process to be used in the measurement mode is executed as described above, a final station selection process is executed in STEP 28. In addition, when only the coordinate information of the station that has been read is used, the processing of STEP 20 to STEP 25 is not executed. Next, in STEP 27, it is determined whether or not the input data (selected coordinate information) is sufficient and valid (for example, whether or not the data of the number of measurement points necessary for the calculation is input), and is sufficient and valid. Until then, the processing of STEP14 to STEP27 is repeated. If it is determined in STEP 27 that the data is sufficient and valid, it is determined in STEP 28 whether or not a measurement calculation start request (for example, by the user) has been received, and the processes in STEP 14 to STEP 28 are repeated until there is a start request. Note that the processing of STEP 27 and STEP 28 may be omitted. Next, measurement calculation processing by the information processing means 14 is started in STEP 29, and when a calculation result display request is issued in STEP 30, the calculation result is displayed on the measurement result screen 17A8 in STEP 31. At this time, STEP 30 may be omitted, and the calculation result may be immediately displayed on the measurement result screen 17A8. Next, in STEP 32, it is determined whether or not a simple diagram display request is received from the user. If there is a display request, the simplified diagram is displayed on the simplified diagram display screen 17A10 in STEP 33. Next, in STEP 34, it is determined whether or not the user has requested to end the entire process. If there is an end request, the entire process is terminated. If the determination result in STEP 30 or STEP 32 is NO, the process in STEP 34 is immediately executed. On the other hand, if the determination result in STE 34 is NO, the main menu is displayed again in STEP 12 and new geometric information processing (arithmetic processing or the like) is executed.
