[Functional configuration]
Next, the functional configuration of the motion measuring device 1 will be described.
FIG. 2 is a functional block diagram illustrating a functional configuration for executing the motion measurement process among the functional configurations of the motion measurement device 1 in FIG. 1.
The motion measurement process is based on the GPS positioning data acquired from the GPS module 19 and the like and the map data stored in the map data storage unit 71 of the ROM 16 to correct the distance represented by the course on the map data and actually travel. It is a series of processes for calculating distances on a course and calculating data relating to various exercises using the calculated distance data. In the present embodiment, course data relating to actual traveling generated based on the map data and the correction data can be recorded on the removable medium 31.

  When exercise measurement processing is performed, as shown in FIG. 2, in the control unit 11, a positioning data acquisition unit 51, a positioning control unit 52, a route specifying unit 53, a correction data calculation unit 54, and travel distance data correction are performed. The unit 55, the exercise data calculation unit 56, and the display control unit 57 function. In addition, a map data storage unit 71 is formed in the ROM 16.

  The map data storage unit 71 holds map data serving as a user's travel course. The map data includes route network data composed of nodes and links.

The positioning data acquisition unit 51 acquires positioning data related to the current position of the motion measurement device 1 from the GPS module 19 in accordance with an instruction from the positioning control unit 52.
The positioning control unit 52 controls the positioning operation in the motion measuring apparatus 1 such as acquisition of positioning data and recording of positioning data. For example, the positioning control unit 52 determines landing in walking or running based on acceleration data, and when there is landing, counts the number of steps, acquires positioning data from the GPS module 19, every predetermined time The recording of the positioning data and the acquisition of the current time from the clock circuit 15 are controlled.

The route specifying unit 53 specifies a traveling route from the map data held by the map data storage unit 71 based on the GPS positioning data acquired by the positioning data acquisition unit 51.
Specifically, the route specifying unit 53 extracts data of a route at a position near the current position from the map data storage unit 71 based on the current positioning data. In addition, the route specifying unit 53 extracts the data of the route having the highest parallelism with the GPS trajectory based on the GPS positioning data of a plurality of points acquired by the positioning data acquisition unit 51.
In this embodiment, candidates such as a jogging course and a training course including a route corresponding to the data extracted by the route specifying unit 53 are displayed, and one course selected by the user using the input unit 13 is specified, and exercise is performed. It may be set in the measuring device 1. Candidate data such as a jogging course and a training course can be registered in advance in the motion measuring apparatus 1 or acquired via a network.

Here, the process in which the route specifying unit 53 specifies the route will be specifically described with reference to FIG.
FIG. 3 is a diagram showing a traveling course C represented by route data in the map data held by the map data storage unit 71.
In FIG. 3, each point of G1-G5 has shown the present position on the map corresponding to the positioning data which the positioning data acquisition part 51 acquired in order. Since the GPS positioning data includes errors, the direction of the vector V1 from G1 to G2, the vector V2 from G2 to G3, the vector V3 from G3 to G4, and the vector V4 from G4 to G5 are in the traveling direction as shown in the figure. On the other hand, it includes variations from side to side.

  In order to reduce the variation due to such an error, the route specifying unit 53 performs an averaging process of variations in positioning, averages the directions of the vectors V1 to V4, and adds them, thereby adding G1 → G5. The averaged vector Va is obtained. This averaged vector Va is the average direction of the GPS trajectory based on a plurality of GPS positioning data acquired by the positioning data acquiring unit 51, and the route specifying unit 53 is a route having the highest parallelism with the averaged vector Va. Extract the data.

Returning to FIG. 2, the correction data calculation unit 54 includes GPS trajectory data (averaged vector Va) representing the GPS trajectory based on the GPS positioning data of the plurality of points acquired by the positioning data acquisition unit 51 and the route specified by the route specifying unit 53. The travel distance correction data (route width RW, which will be described later) for the identified route is calculated by comparison with the route data representing the reference line (center line CL).
Hereinafter, the process in the correction data calculation unit 54 will be described.

  The route (travel course C) based on the map data is specified by the method described with reference to FIG. However, in practice, it is rare that the vehicle travels on the center line CL of the traveling course C, and in many cases, it is considered that the vehicle travels on the inner periphery side or the outer periphery side (for example, a sidewalk on the left and right sides of the route). . Therefore, the width of the route (in the case of the example shown in FIG. 3, the width of the traveling path on one side of the upper and lower lines) is compared with the case where the traveling course C is circulated so as to follow the center line CL of the route (traveling course C). ) Due to RW, the actual travel distance is shortened or extended more than the distance calculated from the route data alone. This is because, generally, route data is registered with reference to the center line CL, and the distance to follow the center line CL is also calculated in calculating the distance.

For this reason, the correction data calculation unit 54 compares the GPS trajectory data representing the GPS trajectory (that is, the above-described averaged vector Va) with the route data representing the center line CL of the route identified by the route identifying unit 53. The width RW data is obtained as correction data. Then, using this correction data, the travel distance data correction unit 55 performs a correction process on the travel distance data based on the map data.
The travel distance data correction unit 55 corrects the travel course C determined by the route based on the map data to an actual travel locus based on the correction data (route width RW) by the correction data calculation unit 54.

Specifically, the travel distance data correction unit 55 reduces or expands the shape of the route network specified as the travel course C by the width RW of the route to generate map data (more specifically, the route side of the route in the map data). To the actual travel trajectory represented by the GPS trajectory data. The shape of the route network enlarged or reduced in this way can be obtained by changing the distance represented by the map data at the same reduction rate or enlargement rate, so that a more accurate travel distance can be calculated. .
Thus, by calculating the actual travel distance accurately, the average stride of one step can be accurately obtained by dividing the travel distance by the value of the pitch (number of steps).

The exercise data calculation unit 56 uses the travel distance corrected by the correction data calculation unit 54 to calculate data related to various exercises. For example, the exercise data calculation unit 56 calculates the stride by dividing the corrected travel distance by the pitch, or calculates the travel speed by dividing the corrected travel distance by the travel time.
The display control unit 57 displays the actual traveling course on the LCD 14 so as to be superimposed on the map data based on the actual traveling course data stored in the removable medium 31 as described above. The display control unit 57 displays data related to various exercises calculated by the exercise data calculation unit 56 on the LCD 14. At this time, the display control unit 57 may display the actual traveling course and the data related to the exercise at each position of the traveling course in association with each other.

Next, the operation will be described.
FIG. 4 is a flowchart for explaining the flow of the motion measurement process executed by the motion measurement device 1 of FIG.
The motion measurement process is started by accepting a user start operation at the input unit 13 of the motion measurement device 1. In executing the motion measurement process, the motion measurement device 1 starts measurement by the sensor unit 12 of FIG. Specifically, an acceleration detection value or the like in the triaxial acceleration sensor of the sensor unit 12 is read.

In step S401, the positioning control unit 52 determines the presence or absence of landing due to the user wearing the motion measurement device 1 walking or running based on the detected acceleration value of the three-axis acceleration sensor of the sensor unit 12 (hereinafter, referred to as “determination”). This is called “landing determination” as appropriate.
When the landing determination result is “with landing”, YES is determined in step S401, and the process proceeds to step S401.
On the other hand, when the landing determination result is “no landing”, it is determined as NO in Step S401, and the process proceeds to Step S403.
In step S402, the positioning control unit 52 starts counting the number of steps.

  In step S <b> 403, the positioning control unit 52 acquires GPS positioning data by the positioning data acquisition unit 51.

In step S <b> 404, the positioning control unit 52 starts a time counting operation that is a count of seconds based on the output of the clock circuit 15.
In step S405, the positioning control unit 502 determines whether or not the position by GPS positioning has been confirmed (that is, whether or not an effective GPS positioning result has been obtained). This makes it possible to determine when the current position is calculated or when it is impossible to measure the position because the GPS signal cannot be received from the hygiene, and the motion measurement process in the section where the position by GPS positioning can be reliably acquired. It can be performed.

When the position by GPS positioning is fixed, it determines with YES in step S405, and a process transfers to step S406.
On the other hand, when the position by GPS positioning is not fixed, it determines with NO in step S405, and a process transfers to step S409.
In step S406, it is determined whether or not the position determined to be confirmed in step S405 is a position that is first confirmed after starting measurement in a predetermined section (step S406). The position determined first in the predetermined section is, for example, the position determined first in the section between the nodes in the map data, and corresponds to the position of G1 in FIG. The above averaged vector Va is calculated using the position first determined in the predetermined section.

If the position determined to have been determined in step S405 is the position determined for the first time after starting measurement in a predetermined section, it is determined YES in step S406, and the process proceeds to step S407.
On the other hand, if the position determined to have been determined in step S405 is not the position determined first after starting the measurement in the predetermined section (that is, the position determined after the second), NO is determined in step S406. Then, the process proceeds to step S408.
In step S407, the positioning control unit 52 records the position determined to be confirmed in step S405 as the first position in the predetermined section.

In step S408, the positioning control unit 52 records the position determined to be confirmed in step S405 as the second and subsequent positions in the predetermined section. The second and subsequent positions in the predetermined section correspond to positions G2 to G5 in FIG. 3, for example.
After step S407 and step S408, the process proceeds to step S409.
In step S409, the positioning control unit 52 determines whether or not the number of positioning points whose positions determined by GPS positioning are determined is recorded in advance.

If positioning points whose positions determined by GPS positioning have been determined are recorded for a preset number of points, YES is determined in step S409, and the process proceeds to step S410.
On the other hand, when the positioning point where the position by GPS positioning is determined is not recorded by the preset number of points, it determines with NO in step S409, and a process transfers to step S401.

In step S410, the route specifying unit 53 executes an averaging process of variations in positioning based on the positioning points recorded in the predetermined section. Thereby, the averaged vector Va in FIG. 3 is calculated.
In step S411, the route specifying unit 53 starts execution of the travel information calculation process.
When the travel information calculation process in step S411 is completed, the process returns to step S401.

Next, the travel information calculation process executed in step S411 of the motion measurement process will be described.
FIG. 5 is a flowchart for explaining the flow of the travel information calculation process.
In step S501, the route specifying unit 53 refers to the map data stored in the ROM 16 in FIG. 1 (the map data storage unit 71 in FIG. 2), and the averaged vector Va by GPS positioning is used to calculate the route in the map data. It is determined whether or not it is within an allowable amount that can be determined as the same vector as a vector (for example, a vector of links connecting nodes).

In step S501, as shown in FIG. 3, the route specifying unit 53 has the highest parallelism between the traveling direction based on the GPS positioning and the GPS trajectory by the average of the plurality of positioning points acquired by the positioning data acquiring unit 51. High route data is determined.
In step S502, the correction data calculation unit 54 calculates the difference between the route vector in the map data and the GPS trajectory by the average of a plurality of positioning points (the average of the distances of the positioning points from the route center line CL).
The above difference (the average of the distances of the positioning points from the route center line CL) corresponds to the route width RW in FIG. 3, and therefore the route width does not change when the difference is constant. means.

In step S503, the correction data calculation unit 54 determines whether or not the difference between the route vector in the map data and the GPS trajectory by the average of a plurality of positioning points (that is, the route width (width RW)) has changed. .
When the difference between the vector of the route in the map data and the GPS trajectory by the average of the plurality of positioning points has changed, YES is determined in step S503, and the process proceeds to step S504.
On the other hand, if the difference between the route vector in the map data and the GPS trajectory by the average of the plurality of positioning points has not changed, NO is determined in step S503, and the process proceeds to step S505.

In step S504, the correction data calculation unit 54 corrects data related to the route width (width RW).
In step S505, the correction data calculation unit 54 records data relating to the current route width (width RW).

  In step S506, the travel distance data correction unit 55 corrects the travel distance based on the map data based on the route width recorded in step S505, calculates the actual travel distance, and records the calculated travel distance data. To do. Specifically, the mileage data correction unit 55 reduces or expands the shape of the route network in the map data by the width RW of the route and matches the shape on the road side of the route in the map data, so that the GPS trajectory data is obtained. It is corrected to the actual traveling locus that represents. The travel distance data correction unit 55 calculates travel distance data by reducing or expanding the length of the route network. Thereby, in the case of a bent route or the like, the course inside the center line CL is shorter, and the course outside the center line CL is corrected longer.

  In step S507, the exercise data calculation unit 56 determines whether or not the count value of the number of seconds started in step S404 in FIG.

If the count value of the number of seconds has reached 60, YES is determined in step S507, and the process proceeds to step S508.
On the other hand, if the count value of the number of seconds has not reached 60, NO is determined in step S507, and the process returns to the motion measurement process.
In step S508, the exercise data calculation unit 56 calculates and records the average pitch number. That is, in step S508, the average number of pitches is calculated based on the count value of the number of steps in step S402 of FIG. 4 and the time data corresponding thereto.

  In step S509, the exercise data calculation unit 56 calculates an average stride. The average stride is calculated by dividing the actual travel distance calculated in step 506 by the step count value in step S402 in FIG.

  In step S510, the exercise data calculation unit 56 calculates the travel speed. The travel speed is calculated by dividing the actual travel distance calculated in step 506 by the corresponding time data.

By executing the processing as described above, the actual travel locus of the motion measuring device 1 (that is, the user who wears it) can be obtained more accurately, and therefore the actual travel distance can be calculated more accurately. it can.
In addition, the accuracy of data calculated based on the travel distance such as travel speed and stride can be increased.

The motion measuring apparatus 1 configured as described above includes a positioning data acquisition unit 51, a route identification unit 53, a correction data calculation unit 54, and a travel distance data correction unit 55.
The positioning data acquisition unit 51 acquires positioning data indicating the current position of the motion measurement device 1.
The route specifying unit 53 specifies a moving route in the map data based on the positioning data acquired by the positioning data acquiring unit 51.
The correction data calculation unit 54 determines the trajectory of the specified route based on the comparison between the trajectory represented by the plurality of positioning data acquired by the positioning data acquisition unit 51 and the reference line of the route specified by the route specifying unit 53. Calculate the difference.
The travel distance data correction unit 55 calculates the travel distance of the electronic device from the route distance information specified by the route specification unit 53 based on the difference calculated by the correction data calculation unit 54.
Thereby, the distance of the route specified from the positioning data can be corrected according to the relationship between the reference line of the route and the moved locus, and the actual distance of the moving locus can be obtained.
Therefore, the distance of the movement trajectory can be calculated with higher accuracy.

In addition, the travel distance data correction unit 55 reduces or enlarges the route specified by the route specifying unit 53 in the map data according to the trajectory, and the distance information of the specified route represented by the map data is the same reduction rate or The movement distance of the motion measuring device is calculated by changing the magnification.
Thereby, the exact distance of a movement locus can be easily calculated.

In addition, the travel distance data correction unit 55 changes the route distance information specified by the route specification unit 53 so as to reduce the route information when the position of the trajectory with respect to the reference line of the route is inside the bend of the route. If the position of the trajectory with respect to the reference line is outside the bend of the route, the movement distance of the motion measuring device is calculated by changing the distance information of the route specified by the route specifying unit 53 to be enlarged.
This makes it possible to correct the distance depending on whether the route is moving inside or outside the course with respect to the reference line (center line or the like) of the route.

  In addition, this invention is not limited to the above-mentioned embodiment, The deformation | transformation in the range which can achieve the objective of this invention, improvement, etc. are included in this invention.

In the above-described embodiment, when the travel distance data correction unit 55 reduces or enlarges the shape of the route network corresponding to the value of the width RW, it may be performed in a range including a portion other than the straight line in the route network.
Thereby, when matching the map data by reducing or expanding the shape of the route network, matching can be performed more easily.
In addition, when reducing or enlarging a straight line part in the shape of the route network, it may be possible to delete the auxiliary part after the part other than the straight line is included and reduced or enlarged.

In the above-described embodiment, when the GPS trajectory crosses the center line CL, the correction data calculation unit 54 may calculate the correction data by dividing the section with the point as a boundary.
That is, when the GPS trajectory crosses the center line CL, it is considered that the user of the motion measurement device 1 has crossed the sidewalk on the opposite side. The travel distance can be calculated.

In addition, the driving data shown in FIG. 1 is combined with attribute data such as data representing a runner (name, sex, age, height, weight, competition history, etc.) and date / time data. The data may be stored in the removable medium 31 via 22.
Thereby, even when the exercise measuring device 1 of the present embodiment is shared by a plurality of users, the data relating to the exercise status for each individual user is organized. Therefore, appropriate advice and health management guidelines for each user can be obtained with reference to the data related to the exercise status for each user arranged in this way.
