Abstract

A distance measurement correction device () corrects distance measurement information () between a sensor () and a body. A movement calculation unit () calculates respective movement distances of the body with respect to the sensor () in a plurality of directions as pieces of movement information (), on the basis of a difference between distance measurement information () measured on a current occasion by the sensor () and distance measurement information measured on a previous occasion by the sensor (). A correction direction extraction unit () calculates movement velocities of the body as body movement velocities using the respective pieces of movement information () for the plurality of directions and extracts a direction, for which the distance measurement information () is to be corrected, as a correction direction () from among the plurality of directions, on the basis of the body movement velocities. A distance measurement information correction unit () calculates a distance from the sensor () to the body for the correction direction () at a correction time point between a time point of measurement on the previous occasion by the sensor () and a time point of measurement on the current occasion by the sensor as post-correction distance measurement information ().
