Abstract

PROBLEM TO BE SOLVED: To provide a movement track detection device capable of precisely detecting a movement track while saving the power by receiving intermittently.SOLUTION: The movement track detection device determines whether a walking course storage stores a registered course which includes points with which continuous "previous position" and "present position" are coincide (SW207). When the storage stores the points (SW207; YES), the movement track detection device reads out the registered course from the storage and determines that the read-out course is the course on which a user has started walking (step S212). Subsequently, the movement track detection device performs a track interpolation processing and performs an interpolation to connect the "previous position" and the "present position" by coloring the road (step SW213). Also, the movement track detection device performs an interpolated track recording processing to add the track between the "previous position" and the "present position" to additionally record the same in the track data storage (step SW214). With this, the track data storage stores a continuous movement track from the start point to the present point.

Description

  The present invention relates to a movement locus detection apparatus, a program, and a movement locus detection method for detecting a locus when a user moves by walking, jogging, or the like.

  Conventionally, as a movement trajectory detection technique for detecting a movement trajectory, one disclosed in Patent Document 1 below is known. In this technique, when a user carries a portable device and performs walking or the like, the portable device intermittently receives a signal from a GPS satellite, and calculates the current position of the portable device each time the signal is received. Then, position information including the calculated position of the portable device and the time when the signal from the GPS satellite used for the calculation is received is sent from the portable device to the center. Then, the center corrects the current position of the portable device sent from the portable device and maps it on the map as appropriate. As a result, a movement trajectory composed of a series of points mapped by correcting the current position of the portable device sent from the intermittent portable device is obtained on the map.

JP 2002-318127 A

  As described above, according to the conventional technique, a movement locus composed of a series of mapped points is obtained by mapping on the map based on the current position of the portable device sent from the portable device. Therefore, in order to detect the trajectory with high accuracy, reception of a signal from a GPS satellite, calculation of the current location based on the received signal, transmission of the calculated current position and the reception time of the signal from the GPS satellite to the center is high. It is necessary to ensure a sufficient mapping frequency by performing at a frequency. As a result, a large amount of power is consumed from the battery as a power source in a short time, and the movement locus cannot be detected over a long distance over a long time.

  On the other hand, if the frequency of reception of signals from GPS satellites, calculation of the current location based on the received signals, transmission of the calculated current position and the reception time of signals from the GPS satellites to the center is reduced, battery power Since consumption is reduced, it is possible to detect the movement trajectory over a long distance for a long time. However, if the frequency of receiving GPS signals, calculating the current location, calculating the current position, and transmitting the GPS reception time to the center is lowered, the mapping frequency is naturally reduced on the map, and the mapping point interval is wide. turn into. As a result, an error occurs between the movement locus detected by the continuation of the mapped points and the actual movement locus, and the movement locus cannot be detected with high accuracy.

  Of course, if a large battery is mounted, it is possible to detect the movement trajectory over a long distance for a long time. However, when a large battery is installed, the portable device becomes large with this, which hinders exercise.

  The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a movement locus detection apparatus, a program, and a movement locus detection method capable of detecting a movement locus with high accuracy while saving power by intermittent reception. .

  In order to solve the above-mentioned problem, the present invention is detected intermittently by a course storage means that stores a plurality of courses indicating movement paths, a current position detection means that intermittently detects a current position, and the current position detection means. A determination means for determining whether the current movement route is one of the courses by comparing the current position of the current route and the movement routes indicated by the plurality of courses stored in the course storage means; According to another aspect of the present invention, there is provided a movement trajectory detection apparatus comprising: a movement trajectory detection means for detecting a movement trajectory based on a course determined by the means and a current position detected by the detection means.

Further, according to the present invention, a computer having an apparatus including a course storage unit that stores a plurality of courses indicating a movement route is intermittently detected by a current position detection unit that intermittently detects a current position, A determination means for determining whether the current movement route is any one of the courses by comparing the current position detected in the step and a movement route indicated by a plurality of courses stored in the course storage means; And providing a computer-readable program that functions as a movement trajectory detection means for detecting a movement trajectory based on the course determined by the determination means and the current position detected by the detection means. .

  Further, the present invention shows a current position detecting step for intermittently detecting a current position, a current position intermittently detected in the current position detecting step, and a plurality of courses stored in course storage means. Based on the determination step for determining whether the current movement route is one of the courses by comparing the movement route, and the course determined by the determination step and the current position detected by the detection means And a moving locus detecting step for detecting the moving locus.

  According to the present invention, it is possible to accurately detect a movement trajectory during running, jogging, walking, or the like while saving power by intermittent reception. Therefore, it is not necessary to mount a large battery, and it is possible to prevent an increase in the size of the device due to the mounting of the large battery, and to achieve a small device that does not hinder movement even when carried.

(Outline of the embodiment)
In this embodiment, a course for walking, running, taking a walk, etc. by some method is registered in advance in the apparatus. Information to be registered is only travel route information. The device is equipped with a device that measures the absolute position such as GPS and can identify the current location, and records the position and time of the measurement.

When receiving the position intermittently with this device, if the position of the course data recorded in advance and the position of the intermittent reception are very close, it is determined that you are walking or running on the course. In addition, it is judged that the place where the positioning between the two points received intermittently is not performed is passing through the course registered in advance, and that route is added to the record as a locus during intermittent reception. To do. At that time, the average speed is calculated from the time difference between the two points and the course path, and the time of the course position information added to the movement locus is derived from the average speed and registered. Until the next intermittent reception is performed, the average speed calculated last time is used as a temporary moving speed to obtain the current position. Similarly, if intermittent reception is performed, the position information used temporarily is discarded, the average speed is calculated from the time difference between the above two points and the path, and the location and time moved from that value are added to the record. We will create a trajectory.
That is, course data set in advance as a walking or running course is registered in a moving locus acquisition apparatus equipped with a device capable of positioning such as GPS. When you start running and intermittently perform position measurement and specify the position, one course is gradually selected from the group of registered courses, and by running that course you can make a precise locus even with intermittent reception It is a device that can.

  FIG. 3 is a block diagram illustrating a circuit configuration of the PC 3. As illustrated, the PC 3 includes a control unit 302, an HDD (Hard Disk) 303, a RAM (Random Access Memory) 304, a sound processing unit 305, a graphic processing unit 306, a DVD / CD, which are connected to each other via a bus 301. A ROM drive 307, a communication interface 308, and an interface unit 309 are provided.

  The control unit 302 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), and the like, and a program stored in the RAM 304 based on a boot program stored in the ROM and a basic program such as an OS (Operating System). Are sequentially executed to perform various processes and control the operation of each unit in the PC 3 main body. The HDD 303 stores a program fetched from the interface unit 309 via the communication interface 308, the Internet 4, and the USB port 320, map data, and other data.

  The RAM 304 is used as a main memory, and stores programs and data transferred from the DVD / CD-ROM 310. The RAM 304 is also used as a work area during program execution. The sound processing unit 305 includes a speaker that performs processing for reproducing sound data in accordance with an instruction from the control unit 302, outputs the sound data as an audio signal, and reproduces the audio signal.

  The graphic processing unit 306 generates various image data in accordance with instructions from the control unit 302, and the graphic processing unit 306 adds a predetermined synchronization signal to the generated image data and outputs it as a video signal to the display device 311. To do. The DVD / CD-ROM drive 307 drives the DVD / CD-ROM 310 set in the PC 3 in accordance with an instruction from the control unit 302, and the program and data stored in the DVD / CD-ROM 310 are transmitted via the bus 301. To the RAM 304. The communication interface 308 is connected to the external Internet 4 via a communication line, and performs processing for exchanging programs and data with the external Internet 4 in accordance with instructions from the control unit 302.

  A keyboard 312 and a mouse 313 are connected to the interface unit 309. The interface unit 309 controls data exchange between the keyboard 312 and mouse 313 and the control unit 302 or RAM 304. The HDD 303 stores various programs and programs and various data for operating the PC 3 as a terminal device in the application distribution system, which are shown in the flowcharts described later. The DVD / CD-ROM 310 is driven by a DVD / CD-ROM drive 307 and reads stored programs and data.

The display device 311 includes a display screen including a liquid crystal panel that displays an image corresponding to the video signal from the graphic processing unit 306.

(Course creation)
FIG. 4 is a flowchart showing a processing procedure of course creation processing for creating a walking course using the PC 3 in the present embodiment. The control unit 302 of the PC 3 executes processing as shown in this flowchart based on a program stored in the ROM. That is, the locus use range designation process is performed, and the course desired by the user is written on the map displayed on the display device 311. For example, the pointer is moved according to the operation of the mouse 313 and the course is drawn on the movement locus of the pointer. Thereby, as shown in FIG. 5A, a virtual walking course 355 drawn freehand is displayed on a map 351 displayed on the display device 311.

  However, since this virtual walking course 355 is drawn by a manual operation by a user by dragging, it does not necessarily match the road on the map. Therefore, the virtual walking course 355 is incomplete, most of which cannot be walked.

  Therefore, next, a road matching process is performed to sequentially extract the virtual walking course 355 from the map that can be walked at a position closest to the virtual walking course 355, and the extracted roads are sequentially combined to generate a walking course ( Step SP102). Thereafter, a course display process is performed, and the course on which the road matching process has been performed is displayed on the display device 311 (step SP103). Therefore, as shown in FIG. 5B, the modified walking course 356 in which the virtual walking course 355 of FIG. 5A is corrected to be walkable is displayed on the display device 311 by the processing in step SP103.

  Next, it is determined whether or not there has been a course correction instruction by an operation on the user's keyboard 312 or the like (step SP104). If not, course registration processing is executed, and this corrected walking course 356 is displayed together with map data. Saving in the HDD 303 (step SP105). If there is a course correction instruction, the course correction process is executed (step SP106), and then the process from step SP102 is repeated.

  Therefore, a plurality of walking courses are registered in the HDD 303 by executing the course creation process shown in FIG. In addition, the walking course taken in from the outside via the Internet 4 can be stored in the HDD 303 as well as the case where the PC 3 is created in this way. As a result, a number of famous courses such as the Tokyo Marathon, Honolulu Marathon, and the Imperial Palace Jogging Course are registered in the HDD 303 as data indicating the route.

(Course registration)
FIG. 6 is a flowchart illustrating a course registration process performed by the wrist terminal 1 according to the present embodiment. When connected to the PC 3 via the USB cable 2 and communicable with the PC 3, the control unit 102 of the wrist terminal 1 executes processing as shown in this flowchart based on a program stored in the ROM. That is, the map data display process is executed, the map data stored in the map data storage unit 102 is read, and a map based on the read map data is displayed on the display unit 101 (step SW101). Subsequently, a walking course input process is performed to sequentially input course data of the selected walking course stored in the HDD 303 of the PC 3.

  At this time, it is preferable to let the user know that the walking course is being entered by following the input of the course data and displaying the course in a colored manner on a map displayed on the display unit 101.

  Next, it is determined whether or not the input of this course has been completed, that is, whether or not the input of all the course data of the walking course has been completed (step SW103), and from step S102 until the input of all the course data has been completed. Repeat the process. When the input of all the course data is completed, this walking course is stored in the walking course storage device 109.

  Therefore, when the course registration process shown in FIG. 6 is executed a plurality of times, a plurality of walking courses registered in the HDD 303 of the PC 3 are copied and stored in the walking course storage device 109.

  The wrist terminal 1 is provided with an Internet connection function so that the walking course storage device 109 can store not only walking courses registered in the HDD 303 of the PC 3 but also walking courses imported from the outside via the Internet 4. It may be. In this way, as in the case of PC3 described above, a number of famous courses such as the Tokyo Marathon, Honolulu Marathon, and pre-Imperial Jogging Course are stored in the walking course storage device 109 with data indicating the route and the like. Can do.

  In storing the course in the walking course storage device 109, if a part of the course to be registered overlaps with the already registered course, the registration is rejected during the registration process in step SW104. The Therefore, the walking course storage device 109 stores a plurality of courses configured only by independent courses that are not superimposed on the course.

(Track record save)
FIG. 7 is a flowchart showing a processing procedure of trajectory saving processing executed by wrist terminal 1 in the present embodiment. The user wears wrist terminal 1 on his arm and starts walking. At this time, the course in which walking is performed is one of the courses stored in the walking course storage device 109, and walking in other courses is not performed.

  That is, it is determined whether or not the GPS reception time, which is the time for receiving radio waves transmitted from a plurality of positioning satellites (GPS satellites), has been reached (step SW201). When the GPS reception time is reached, the correction processing of the clock that measures the reception interval of the GPS intermittent reception is performed and reset (step SW202). The GPS reception interval is much longer than the conventional intermittent reception interval described above, and is, for example, 10 times, 50 times, 100 times, or the like. Then, the current position is calculated from the received GPS radio wave (step SW203).

  On the other hand, in a part of the RAM, a “previous area” that stores “previous position” that is the previous current position and “previous time” that is the time when the previous current position is calculated, and the current current position There is provided a “current area” for storing “current position” and “current time” which is the time when the current position is calculated. In step SW204, it is determined whether “previous position” and “previous time” are recorded in the “previous area”. If “previous position” and “previous time” are not recorded in the “previous area”, the process proceeds to step SW206 without performing the process of step SW205.

  If “previous position” and “previous time” are recorded in the “previous area”, the “previous position” and “previous time” recorded in this “previous area” are deleted, and at this point “Current position” and “current time” recorded in “current area” are moved to “previous area” and recorded as “previous position” and “previous time” (step SW205). Therefore, by the processing in step SW205, new “previous position” and “previous time” are recorded in “previous area”, and “current area” becomes blank. Therefore, the “current position” obtained by the calculation in step S203 and the “current time” as the time are recorded in the blank “current area” (step SW206).

  Therefore, in the “previous area” and “current area” of the RAM, the continuous “previous position” and “current position” are recorded while being updated. Therefore, it is determined whether or not a registered course having a point where the consecutive “previous position” and “current position” coincide with each other is stored in the walking course storage device 109 (step SW207). If the registered course having a point where the consecutive “previous position” and “current position” coincide with each other is not stored in the walking course storage device 109, the registered course where the user has started walking is already determined. It is determined whether or not (step S208). If the registered course is not determined, the process from step SSW201 is repeated, and if the registered course is determined, the process proceeds to step SW212.

  Further, as a result of the determination in step SW207, when a registered course having a point where the consecutive “previous position” and “current position” match is stored in the walking course storage device 109 (step SW207; YES). Similarly to step S208 described above, it is determined whether or not the registered course on which the user has started walking has already been determined (step S2089). If the registered course has not been determined, a course determination process is executed (step SW212).

  That is, a registered course having points where the consecutive “previous position” and “current position” coincide with each other is read from the walking course storage device 109, and it is determined that the read registered course is a course in which the user has started walking ( Step S212). Next, a trajectory interpolation process is performed to perform interpolation such as coloring and continuing the road between successive “previous position” and “current position” on the map (step SW213). Further, an interpolation trajectory recording process is executed, and a trajectory between “previous position” and “current position” is added to the trajectory data storage device 110 (step SW214). As a result, the trajectory data storage device 110 stores a continuous trajectory from the start point to the local point.

  Subsequently, the average speed calculation process is executed to calculate the average speed (step SW215). At this time, since “previous position” and “current position” and “previous time” and “current time” are known, “previous position” “current position” = distance, “previous time” − “current time” ] = By time, distance and time are known. Therefore, distance / time = current speed can be calculated. Also, the average speed is calculated by dividing the total of the “current speed” calculated up to this point by the number of calculations.

Subsequently, by the current / predicted position display process, a map is displayed on the display unit 101, the position calculated so far on the map is displayed as a point, and the predicted position is displayed as a point (step SW216). Further, the points of the positions calculated so far are sequentially connected to create an interpolation locus, and the created interpolation locus is displayed (step SW217). Next, it is determined whether or not a switch-off operation, which is an operation for ending this locus record storage, has been performed (step SW217), and the processing from step SW201 is repeated unless the switch is turned off.
On the other hand, if the determination in step SW201 is NO and it is not the GPS reception time, it is determined whether or not the predicted position processing is possible (step S210). At this time, if the course has already been determined, the average speed has been calculated, and the “previous position” and “current position” are also known, the current position can be predicted without GPS information. . Therefore, in this case, the determination in step SW210 is YES, the predicted position process is executed, and the current position or a position that has moved further than the current position is calculated using each element (step SW211). Thereafter, the above-described processing of step SSW 216 is performed.

  Therefore, according to the above embodiment, it is possible to accurately detect a movement locus in walking or the like while saving power by intermittent GPS reception. Therefore, it is not necessary to mount a large battery, and it is possible to prevent an increase in the size of the device due to the mounting of the large battery, and to achieve a small device that does not hinder movement even when carried.

  In step SW215, the average speed is calculated, but the calorie consumption may be calculated. That is, the calorie consumption can be calculated by obtaining the BMI value from the exercise speed calculated as described above and the gender, age, height, and weight previously input by the user.

(Effect of embodiment)
This embodiment is based on the assumption that walking is performed using any one of the registered courses, and it is possible to move without departing from the course. The frequency can be drastically reduced, and in places where position measurement is not performed, the average speed is derived from the course position and position measurement by intermittent reception and the elapsed time, and the position and time are complemented by the position and time. It has become a method that can increase density and reduce consumption.
In addition, it is possible to derive the current position from the course matching process and the average speed prediction value until the next intermittent reception, and only the movement trajectory is obtained even if the number of positioning such as GPS is small. In addition, the current position can be expressed with a certain degree of accuracy.
Comparing this with conventional techniques, the conventional apparatus has used a method of recording a movement locus by continuously measuring using a positioning technique such as GPS. As a result, the travel route is recorded in detail, and the travel speed, calorie consumption, burned fat amount, and the like are calculated. This method is certainly a measurement method with high accuracy.
However, it is a method that performs positioning without missing the positioning method by continuously performing the positioning method using GPS, etc., so that the power consumption becomes very high and a permanent power source such as a car is required. If it is equipped, it will not be a problem, but as a thing to carry when exercising like walking or running, a large battery must be installed to perform positioning for a long time, and it becomes a very big device and exercise It will be an obstacle.
On the other hand, if a small battery is used to improve portability, the battery will not last long, so there is a major drawback that it is not suitable for use unless it can be measured in a short time.
Considering these shortcomings, there is an activity meter that does not have a positioning function of absolute position by GPS etc., that is, only records the step count by a method that does not measure the road and derives calorie consumption, etc. The battery life is good, but since it does not record where you are walking, it is calculated by calculating the calorie consumption etc. from the number of steps recorded and the little information, so the calculation result is only low accuracy There was a problem.
This embodiment is based on the assumption that walking is performed using any one of the registered courses, and it is possible to move without departing from the course. The frequency can be drastically reduced, and in places where position measurement is not performed, the average speed is derived from the course position and position measurement by intermittent reception and the elapsed time, and the position and time are complemented by the position and time. It has become a method that can increase density and reduce consumption.
In addition, it is possible to derive the current position from the course matching process and the average speed prediction value until the next intermittent reception, and only the movement trajectory is obtained even if the number of positioning such as GPS is small. In addition, the current position can be expressed with a certain degree of accuracy.

  In the above embodiment, walking has been described as an example. However, the present invention is not limited to walking, but can be applied to cases where people such as running, jogging, marathon, cycling, and driving move. is there.
