A 3-D shape measurement apparatus for grasping the state of an object with ease and accuracy is provided. The 3-D shape measurement apparatus includes: a first 3-D sensorhaving a projecting devicefor projecting a light pattern on a target area, and a (first) image capturing apparatusplaced at a first interval dfrom the projecting deviceto capture an image of the target area on which the light pattern is projected; a second 3-D sensorhaving a projecting device, and a (second) image capturing apparatusplaced at a second interval dlonger than the first interval dfrom the projecting deviceto capture an image of the target area on which the light pattern is projected; 3-D information computing meansfor obtaining external shape information on an objectbased on the shift of the pattern on the image acquired with the first 3-D sensor; variation information computing meansfor obtaining variation information on the objectbased on the shift of the pattern on the image acquired with the second 3-D sensor; and information composing meansfor composing the external shape information and the variation information.

Three-dimensional shape-measuring device

A monitor which can detect respiration of a sleeping person without being affected by the attitude of the sleeping person or the indoor illumination light and can easily evaluate detected respiration quantitatively through image measurement. The monitor comprises means () for projecting a specified illumination pattern, means () for picking up the image of projected light continuously, means () for calculating inter-frame moving amount of the illumination pattern from the image of two frames acquired by the image pickup means at different times, means () for generating a moving amount waveform data comprising inter-frame moving amounts arranged in time series, and means () for detecting the movement of an object from the moving amount waveform data.
