    • To provide a three-dimensional monitoring apparatus capable of detecting with high accuracy an incoming of an object into a predetermined three-dimensional space by using pattern light as a detecting carrier. A three-dimensional monitoring apparatus comprising (1) an irradiating device for irradiating predetermined pattern light to three-dimensional space S to be monitored, (2) an imaging device for imaging a projection pattern projected by irradiating of the pattern light on an incoming object M and on a screen 5 in the space S to capture image data and (3) a measuring device to measure a position of the object M based on the comparison between a monitoring image captured by the imaging device when there is the object M in the space S and a reference image captured by the imaging device when there is no object M in the space S.
    • 为了提供能够通过使用图案光作为检测载体,以高精度检测物体进入预定的三维空间的三维监视装置。 一种三维监视装置,包括:(1)用于将预定图案光照射到待监视的三维空间S的照射装置,(2)一种成像装置,用于对通过照射所述图案光投影的投射图案对入射物体 M并且在空间S中的屏幕5上,以捕获图像数据;以及(3)测量装置,用于根据在成像装置捕获的监视图像之间的比较来测量对象M的位置,当在 空间S和当空间S中没有物体M时由成像装置拍摄的参考图像。
