    摘要: A three-dimensional model is created to represent an environment to be captured on video. A camera is fitted with pan, tilt and/or zoom sensors. An operator selects a location in the environment. The three-dimensional model is used to determine the three-dimensional coordinates of the location selected by the operator. Information from the pan, tilt and/or zoom sensors is used to transform the three-dimensional coordinates to a two-dimensional position in the video from the camera. Using the two-dimensional position of the video, a graphic is properly added to the video such that the graphic appears to be at the selected location in the environment.

    摘要: A system is disclosed for using camera attitude sensors with a camera. A camera assembly includes a tripod base, a tripod head interface mounted on the tripod base, a tripod head mounted on the tripod head interface and a camera mounted on the tripod head. The tripod head enables the camera to pan and tilt. The system also includes a first optical encoder for detecting the amount that the camera has been panned and a second optical encoder for detecting the amount that the camera has been tilted. Two inclinometers are mounted on the tripod head interface to measure attitude of the tripod head. Two gyroscopes (“gyros”) are mounted on the camera assembly. Data from the encoders, gyros and inclinometers are packaged and sent to graphics production equipment to be used for enhancing video captured by the camera.

    摘要: A two-axis angular rate gyroscopic apparatus is provided having a rotatable dish. The dish has a central hub portion and a plurality of flexible members, each of which extends from the hub portion. The entire disk is electrically conductive and connected to a reference potential. A plurality of electrically conductive members which are mounted end-to-end are located on an insulated plate mounted adjacent to the disk. A motor is provided for rotating the disk at approximately 2000 rpm. In addition, each of the flexible members in the disk has a pie-shaped section removed therefrom in order to increase its flexibility. By increasing the flexibility of the movable members, performance at low motor speeds is facilitated. An electronic circuit provides an output corresponding to the differential capacitance between the rotating disk and the members on the plate mounted adjacent thereto.

    摘要: A two-axis inclinometer having a central electrically conductive member inserted within and spaced from the interior walls of a non-electrically conductive vessel. A plurality of four plates are mounted symmetrically on the exterior surface of the vessel. A dielectric fluid is provided in the gap between the center member and the interior wall of the vessel so as to provide a differential change in the capacitance between opposite plate members as the inclinometer is tilted about an axis perpendicular to its longitudinal axis.
