Abstract
A track estimation device includes: a reliability determination unit configured to determine the reliability of satellite positioning information; an update timing determination unit configured to determine the timing of updating a parameter to estimate track of cycling based on the reliability of satellite positioning information; and an update unit configured to update the parameter based on a result of the timing determination. When the reliability determination unit determines that reliability of the satellite positioning information is low, the track estimation unit estimates the track based on the parameter by autonomous navigation.
Claims16
A track estimation device, comprising:
- a processor;
- and
- a storage unit configured to store a program that is executable by the processor,
- wherein the processor is configured to execute, in accordance with the program stored in the storage unit, processing including:
- reliability determination processing of determining reliability of satellite positioning information;
- update timing determination processing of determining timing of updating a parameter to estimate a track of cycling based on reliability of the satellite positioning information and based on action estimation information on actions including seated, standing, inertial running and walking;
- update processing of updating the parameter based on a result of the determination on the timing;
- and
- track estimation processing of estimating the track based on the parameter by autonomous navigation,
- wherein the parameter includes at least one of (i) a first parameter indicating a relationship between cadence and a travelling distance of a cyclist traveling with a bicycle, and (ii) a second parameter indicating a relationship between a number of steps and the travelling distance of the cyclist.
A method for estimating track implemented with a track estimation device, comprising:
- determining reliability of satellite positioning information;
- determining timing of updating a parameter to estimate track of cycling based on reliability of the satellite positioning information and based on action estimation information on actions including seated, standing, inertial running and walking;
- updating the parameter based on a result of the determination on the timing;
- and
- estimating the track based on the parameter by autonomous navigation,
- wherein the parameter includes at least one of (i) a first parameter indicating a relationship between cadence and a travelling distance of a cyclist traveling with a bicycle, and (ii) a second parameter indicating a relationship between a number of steps and the travelling distance of the cyclist.
A non-transitory computer readable recording medium having stored thereon a program that makes a computer of a track estimation device function as:
