  • Patent number: 7081744
    Abstract: The apparatus can continuously determine the location at which a cable is buried. Location data of a measurement standard position is acquired by RTK-GPS. The azimuth of the moving direction of the apparatus is calculated using the location data. Electromagnetic waves from a metallic wire are received by two electromagnetic signal receiving sections whose locations in the horizontal plane are different from each other, and distances from the measurement standard position to a cable in a measurement base line direction and in the vertical downward direction are calculated using the received electromagnetic signals. The depth of the cable is calculated using the distance in the vertical downward direction. The plane location data of the cable is calculated using the azimuth of the moving direction, the location data of the measurement standard position, and the distance in the measurement base line direction.

  • Publication number: 20060064273
    Abstract: A compact automatic motion control photographing device includes a table supported rotatably to at least a single direction; a servo motor for producing a driving force for rotating the table; and a driving force transmitting mechanism for transmitting the driving force produced by the servo motor to the table, wherein the table is rotated towards a single direction and is stopped every time the table has rotated by a predetermined quantity of rotation, so as to perform photographing using a digital camera fastened to the table. Such a compact automatic motion control photographing device has superior portability, by which panoramic photographing can be easily performed by mounting a camera.

  • Patent number: 6714729
    Abstract: An automatic motion-controlled photographing apparatus, according to the present invention, a rotatable turntable is located above an upper surface of a box of a controller fixedly supported on a tripod, and a camera is set onto the turntable. The turntable, on which the camera is set, is rotated at a given angle of rotation responsive to a signal from a turntable drive circuit disposed in the controller, and a shutter of the camera is turned on via a non-contact signal relay in response to a signal from a shutter drive circuit for photographing the same photograph images, each in one frame, at an angle of 360 degrees as those of an on-site field.
