Abstract: A three-dimensional measuring apparatus, method, and program for acquiring many pieces of information on a pattern of light by a single projection and highly accurate three-dimensional information at high speed. The three-dimensional measuring apparatus comprises a pattern projector serving as projecting means for projecting a pattern of light onto a measurement object, a camera serving as imaging means for capturing an image of the measurement object illuminated with the pattern of light, and a computer for processing data on the image captured by the camera. The computer computes the direction angle of each individual pattern of light which forms the projected pattern of light from the intensity value of the projected pattern of light detected from the captured image, divides the intensity distribution, and computes the depth distance from the phase value at each measuring point of the divided pattern. Thus, highly accurate three-dimensional information is acquired.

Abstract: A three-dimensional measuring apparatus, method, and program for acquiring many pieces of information on a pattern of light by a single projection and highly accurate three-dimensional information at high speed. The three-dimensional measuring apparatus comprises a pattern projector (1) serving as projecting means for projecting a pattern of light onto a measurement object (A), a camera (2) serving as imaging means for capturing an image of the measurement object (A) illuminated with the pattern of light, and a computer (3) for processing data on the image captured by the camera (2). The computer (3) computes the direction angle of each individual pattern of light which forms the projected pattern of light from the intensity value of the projected pattern of light detected from the captured image, divides the intensity distribution, and computes the depth distance from the phase value at each measuring point of the divided pattern. Thus, highly accurate three-dimensional information is acquired.

Abstract: [Problem] To determine the length, area or volume of the whole or some specified portion of various architectural structures by using simple apparatus and operation. [Solution] An object is photographed from vertically spaced multiple points by using a digital camera and the length between multiple measured points on the object in multiple photographed images or the area or volume of a portion thereof surrounded by said measured points is determined based on the position of the multiple measured points on the object in the multiple images and the heights of said multiple photographing points. A digital camera is mounted on a pan head on a tripod to photograph an object from multiple positions by vertically moving the pan head, multiple photographed images and level information of multiple photographing points are input to a computer, and the computer performs computation by clicking multiple measured points on the object in one of said multiple images.
