Abstract
According to one embodiment, a spatial position measurement apparatus, includes: a transmission unit configured to transmit an ultrasonic wave accompanying with a transmission source identifiable from three or more transmission sensors provided on a first object; a detection unit configured to detect the ultrasonic wave received by two or more reception sensors provided on a second object; a distance calculation unit configured to calculate distances between the transmission sensors and the reception sensors based on propagation time of the ultrasonic wave; and a coordinate calculation unit configured to calculate, in a coordinate system where a position of one group out of a group of the transmission sensors and a group of the reception sensors is fixed, positional coordinates of another group based on the distances.
