  In recent years, a system (GPS) has been developed that can receive radio waves transmitted from a plurality of satellites and detect a position at a predetermined point. For example, in a survey field that measures the distance and direction between predetermined points on the earth. It's being used.

  In surveying using GPS, for example, radio waves transmitted from a plurality of (four or more) satellites are received at a predetermined point at the same time by a GPS receiver, and based on the distance between the satellite and the GPS receiver, By specifying the position, positioning data at a predetermined point is acquired. And the distance and direction between predetermined points are measured based on positioning data acquired at a plurality of points.

However, the positioning data obtained at each point includes errors depending on natural conditions and satellite conditions. For this reason, conventionally, in order to obtain more accurate positioning data, a method has been used in which the average value is calculated from a plurality of positioning data obtained continuously at a predetermined interval at the same point, and is used as the positioning data at that point. (For example, refer to Patent Document 1). There is also a method of calculating a standard deviation value as a method of knowing the variation of the plurality of positioning data.

  Hereinafter, an embodiment of a positioning data acquisition system using GPS (Global Positioning System) will be described with reference to the drawings.

  As shown in FIG. 1, the positioning data acquisition system 1 in this embodiment is comprised from the GPS receiver 2 and the positioning data processing apparatus 3 as a positioning data acquisition apparatus.

  The GPS receiver 2 has an antenna for receiving radio waves from a plurality of GPS satellites, collects radio waves at predetermined intervals (for example, at intervals of 1 second) via the antennas, measures its position, and determines the position Data is transmitted to the positioning data processing device 3.

  The positioning data processing device 3 is a portable information terminal (so-called PDA), and includes a receiving unit 5 as data obtaining means capable of receiving positioning data from the GPS receiver 2 and storage as storing means capable of storing positioning data. A display unit 7 as a display unit capable of displaying positioning data, a positioning point distribution map Z (see FIG. 4), which will be described later, and the like, an input unit 8 as an input unit capable of an input operation by a positioning person, It is comprised from the control part 9 as a calculating means which controls these. In the present embodiment, the GPS receiver 2 and the receiving unit 5 of the positioning data processing device 3 are connected via a predetermined serial cable.

  Moreover, the input part 8 is comprised by the transparent touch panel (pressure sensitive sheet) stuck on the display part 7 (for example, liquid crystal panel). Then, by pressing the touch panel with a pointing device or the like, the coordinate point on the pressed touch panel is recognized by the control unit 9.

  Next, the flow of processing in the positioning data acquisition system 1 and the portable information terminal 3 configured as described above will be described with reference to the flowcharts of FIGS.

  As shown in FIG. 2, the portable information terminal 3 first performs a data acquisition process for acquiring positioning data from the GPS receiver 2 in step S101. In this process, the positioning data measured by the GPS receiver 2 is received by the receiving unit 5, and the received positioning data is stored in the storage unit 6. This processing is performed every time the positioning data is received, and the newly received positioning data is sequentially added to the positioning data group stored in the storage unit 6.

  In step S102, an average value calculation process for calculating an average value of a plurality of positioning data is performed. In this process, the average value is calculated based on the positioning data that is the average value calculation target in the positioning data group stored in the storage unit 6 and stored in the storage unit 6. In the present embodiment, the received positioning data is automatically set as an average value calculation target. Therefore, when the positioning data to be excluded from the average value calculation target is not specified in the calculation target determination process (step S104) described later, the average value is calculated based on all the positioning data in the positioning data group.

  In step S103, display processing for displaying a positioning point corresponding to each positioning data and a positioning point distribution map Z (see FIG. 4) marked with an average positioning point corresponding to the average value is performed. The positioning point distribution map Z is displayed in plane coordinates with the vertical axis representing latitude and the horizontal axis representing longitude. In the positioning point distribution diagram Z, the average positioning point P1 is displayed with a “+” mark in the center of the display unit 7, and the average target positioning point P2 corresponding to the positioning data that is the average value calculation target is marked with the “black circle”. The average excluded positioning point P3 corresponding to the positioning data excluded from the average value calculation target is displayed with a “white circle” mark, and the concentric circles F1, F2, and F3 are displayed centering on the average positioning point P1. It has become. The concentric circles F1, F2, and F3 are circles corresponding to a radius of 1 m, a radius of 2 m, and a radius of 5 m around the average positioning point P1, respectively.

  In step S104, calculation target determination processing is performed to determine positioning data that is an average value calculation target. As shown in FIG. 3, in this calculation object determination process, first, in step S201, it is determined whether or not the positioning points P2 and P3 are specified in the input unit (touch panel) 8. Here, when there is no designation, this processing is ended as it is. On the other hand, if the positioning points P2 and P3 are designated, the status of the positioning data corresponding to the designated positioning points P2 and P3 is changed in step S202. Thereby, when a predetermined average target positioning point P2 is designated, the positioning data corresponding to the average target positioning point P2 is excluded from the average value calculation target. As a result, the average target positioning point P2 (black circle) is changed to the average excluded positioning point P3 (white circle). Conversely, when a predetermined average excluded positioning point P3 is designated, positioning data corresponding to the average excluded positioning point P3 is set as an average value calculation target. As a result, the average excluded positioning point P3 (white circle) is changed to the average target positioning point P2 (black circle).

  In step S105, it is determined whether or not the positioning data group that is the average value calculation target has been changed by the calculation target determination process in step S104. Here, if it is determined that there is no change, the present process is terminated as it is. On the other hand, if it is determined that there is a change, the process proceeds to step S102 again. That is, when the positioning data that is the average value calculation target is changed, the average value calculation process (step S102) is performed again, and the average positioning point P1 is re-marked at the position corresponding to the calculated average value again. The determined positioning point distribution map Z is displayed (step S103).

  As described above, each time the positioning data is received, the above-described series of processing is repeated, and the average target positioning point P2 is added to the positioning point distribution map Z, and the position of the new average positioning point P1 is obtained. Then, by separately performing an interrupt process, reception of positioning data is stopped based on the stop operation of the positioning person, and an average value of the positioning data is determined based on the determination operation. The positioner acquires the determined average value of the positioning data as the positioning data of the positioning point. Thereafter, the stored positioning data is erased based on the erasing operation.

  Next, the display mode of the display unit 7 (positioning point distribution diagram Z) and the designation input operation of the positioning points P2, P3 will be described with reference to FIG.

  When the designation input operation by the positioning person is not performed, as shown in FIG. 4A, all the positioning points are displayed as the average target positioning point P2. Here, as shown in FIG. 4B, a positioning point designation frame W is drawn by a pointing device or the like in the input unit (touch panel) 8, and an average target positioning point P2 of two points is designated by the positioning point designation frame W. Then, as shown in FIG. 4C, the designated average target positioning point P2 is changed to the average excluded positioning point P3. At the same time, since the average positioning point P1 moves to a position corresponding to the new average value, the relative positional relationship between the average positioning point P1 and the positioning points P2 and P3 is changed. However, since the average positioning point P1 is always displayed at the center of the display unit 7, it appears that the display positions of the positioning points P2 and P3 have moved on the display unit 7.

  Next, as shown in FIG. 4 (d), when one average excluded positioning point P3 is designated by the positioning point designation frame W (in the case of one point, it is possible to designate one point instead of area designation). As shown in FIG. 4E, the designated average excluded positioning point P3 is changed to the average target positioning point P2. Accordingly, as described above, the positioning point distribution map Z in which the average positioning point P1 is re-marked at the position corresponding to the newly calculated average value is displayed.

  As described in detail above, the positioning points P2 and P3 corresponding to the plurality of positioning data obtained at the same point are displayed in the positioning point distribution map Z. As a result, the distribution state of the plurality of positioning points P2 and P3, that is, the variation of the positioning data can be easily grasped at a glance. In the present embodiment, the average positioning point P1 is displayed at the center of the display unit 7, and the concentric circles F1, F2, and F3 are displayed to further enhance the function and effect.

  Further, by referring to the concentric circles F1, F2, and F3 and seeing how the plurality of positioning points P2 and P3 are gathered, it is possible to grasp whether the positioning accuracy is good or bad. For example, if all the average target positioning points P2 are within the concentric circle F1, the positioning accuracy is quite good, and if a plurality of points are outside the concentric circle F3, it can be determined that the positioning accuracy is very poor.

  Further, a plurality of average target positioning points P2 marked in the positioning point distribution map Z are identified as specific points (for example, points outside the concentric circle F3) that have a great influence when calculating an average value from a plurality of positioning data. Can be easily found out from the above and set as the average target positioning point P2. In the present embodiment, the average positioning point P1 is displayed with a “+” mark, the average target positioning point P2 is displayed with a “black circle” mark, and the average excluded positioning point P3 is displayed with a “white circle” mark. It makes it easy to identify the three parties and improves workability.

  As a result, it is possible to obtain more accurate positioning data (average value of positioning data). Furthermore, it is not necessary to wait until a plurality of better continuous positioning data that does not include a singular point is acquired, and the data acquisition can be shortened.

  Further, in the present embodiment, the positioning target data P2 marked on the positioning point distribution map Z is designated as positioning data to be excluded from the calculation target when calculating the average value of the positioning data, and the average excluded positioning point P3 and The positioning data corresponding to the singular point can be excluded from the calculation target by a relatively simple method of determining by doing.
