摘要： PROBLEM TO BE SOLVED: To easily perform, in a short time, measuring work of the three- dimensional form of an object to be measured. SOLUTION: In a light source means 10, a plurality of stripe pattern. projection lights different in phase are generated, by making lights different in wavelength pass a plurality of intensity-modulated stripe patterns different in phase. While the positional relation of the stripe pattern projection lights is maintained, the lights are synthesized and parallel lights are formed, which are projected on an object 2 to be measured. A stripe pattern reflected image generated on the object 2 is optically or electrically decomposed every wavelength, and independent stripe patterns are obtained. On the basis of the obtained patterns, the three-dimensional form of the object 2 is measured, so that the three- dimensional form can be measured by once measuring the stripe patterns. As a result, measuring work is easily enabled in a short time.

摘要： PURPOSE:To form interference fringes without optical noise stably at a high speed by inserting a moving diffusing plate into an optical path, imparting minute change on interference light, casting the light on a body to be measured, and averaging the reflected light in time. CONSTITUTION:Irregular fluctuation is incessantly imparted on laser light 2 by the minute irregular patterns of the surface of a diffusing plate 20, which is linked to a rotating means 22, and the laser light 2 is cast or a measuring surface 12. The amplitude and the phase of the reflected light from the measuring surface 12 are transmitted through a 1/4-wavelength plate 6C, and the light is converted into the right and left circularly polarized light. The light is split into three beams with a splitting optical system 4. The light beams are transmitted through polarizing plates 16A-16C and become interference fringes. The images of the interference fringes are picked up with TV cameras 18A-18C and inputted into a signal. processing device 30. The phase difference of the circularly polarized light beams is measured. Minute optical fluctuation is imparted on the interference fringes with the diffusing plate 20. The interference fringes are integrated with the photoelectric conversion elements of the cameras 18A-18C at one field unit Therefore, speckle noises caused by dust and the like attached on the surface of glass can be readily removed. Thus, the stabilized interference fringes are obtained.

摘要： PURPOSE:To find a coordinate conversion coefficient, etc., while actually a photograph by calculating three-dimensional spatial coordinates of an object on the basis of the distance of a vector to a restraint plane where a mobile object is present and the angle of rotation of a camera. CONSTITUTION:A controller 14 is equipped with a position arithmetic unit 16 which calculates the three-dimensional spatial coordinates of the object, and a driving control unit 17 which obtains information on the angle of rotation, zooming, focusing, a stop, etc., from a zoom lens 12 and a motor-driven universal head 13 and supplies the information to the position arithmetic unit 16. In this case the position of the object on a screen is obtained from an image position measuring instrument and the position is converted into a position on a projection surface (VT surface) as a plane in the space of the image position measuring instrument. Then the vector from the center of the projection to the center of rotation of the universal head 13 is regarded as an aimed vector. The vector is rotated around the center of rotation of the universal head 13 by the tilt of the universal head 13. The point where the straight line obtained by extending the rotated aimed vector and the restraint plane cross each other is the position of the object in the three-dimensional space.

摘要： PURPOSE:To measure three-dimensional space information of each moving object by providing a prescribed number or more of imaging means that take images of the moving body. CONSTITUTION:For example, at the soccer sport, three or more tracking heads MH1-MH6 and three or more fixing cameras FC1-FC6 are provided as imaging means for imaging moving objects (players). Normally, the moving object is measured by means of a set of three tracking heads. At that time, players that can be measured are those in a region of a common part of fields of view of the set of the three tracking heads MH1, MH2, MH6. The object is imaged by zooming-up the tracking heads MH1-MH6 to best of its ability and the affection from the background is reduced, then the image thereof is not so much expanded so that the accurate and stable measurement can be achieved. Therefore, in order to avoid making an object that is not imaged, the fixing cameras FC1-FC6 each having wide angle lens are additionally used. Three- dimensional information of the object is calculated based on the image information from each of the heads MH1-MH6 and each of the cameras FC1-FC6.
