Abstract
An information processing apparatus includes a reducing unit that performs reduction processing to reduce a position or a posture. The information processing apparatus further includes a correcting unit that performs correction processing to correct a reduction error that is caused by the reduction processing, based on temporal change data indicating changes over time relating to the position or the posture.
Claims11
An information processing apparatus, comprising:
- a lowpass filter unit configured to:
- remove a component, higher than a cutoff frequency of the lowpass filter unit, from first speed data based on at least one of a position of the information processing apparatus or a posture of the information processing apparatus;
- and
- output second speed data based on the removal of the component higher than the cutoff frequency;
- a reducing unit configured to:
- execute a reduction process to reduce a change of the at least one of the position or the posture, wherein the reduction process is executed based on the second speed data;
- and
- acquire reduction data based on the execution of the reduction process;
- a subtraction unit configured to calculate a reduction error based on a difference between a displacement signal and the reduction data, wherein
- the displacement signal corresponds to the second speed data output from the lowpass filter unit;
- and
- a correcting unit configured to execute a correction process to correct the reduction error, wherein
- the correction process is executed based on temporal change data, and
- the temporal change data indicates a temporal change associated with the at least one of the position or the posture.
