Abstract
The stride is an important parameter in human motion analysis and has been
extensively studied by many researchers. This paper focuses on smartphones
that are popular in the world, regardless of the measurement environment.
In previous research, the stride estimation using the acceleration sensor
or the gyro sensor mounted on the smartphone had been studied. However,
the stride estimation accuracy has an error rate of about over 10 %. In
this paper, we propose a highly accurate stride estimation method using
stride correction parameter obtained from cross section movement in addition
to conventional sagittal surface stride using acceleration sensor and gyro
sensor mounted on a smartphone. Based on the testing results, the error
rate of our proposed method with the stride estimated by the Kinect sensor
(RGB-D sensor) as the true value was about 6%. It makes possible to estimate
the stride with high accuracy.
