    摘要： The present invention relates to a device for optically detecting position and/or attitude of an object (5) moving in a given zone of travel (4), said device comprising electro-optical sensors disposed on said object and distributed into groups, called clusters (6), analysis and calculation means (2) making it possible to retrieve the position and/or the attitude of said object, electronic means for generating images (1) and optical projection means (1) comprising a display and a projection optic. It is characterized in that the optical projection means emit in a projection cone an image (3) which is sharp at every point of the zone of travel, the analysis of the signals received by the sensors of at least one cluster making it possible to reference the position and/or the attitude of the object in a reference frame defined by the projection means, this frame consisting of a plane perpendicular to the projection axis, termed the image plane, and of the projection axis.

    摘要： A head tracker system for determining a user's head orientation relative to a datum comprises: a head mounting, preferably a helmet (2), for attachment to the user's head and a sensor system (10, 12) for sensing the orientation of the head mounting (2) relative to the datum. A distinguishable marking (26) is provided at a first known point fixed relative to the head mounting or a second known point fixed relative to the datum. At the other known point an optical sensor (18), preferably a video camera, is mounted. The system further comprises processing means (28) for determining when the marking is within the field of view of the optical sensor and the output of the processing means is used to correct for drift in the sensor system or to provide an independent verification that the system is functioning within preselected tolerances.

    摘要： A head mounted tracker is placed in the operator area near the operator. The tracker is both metal immune and has the capability to mathematically map the operator area. These operations are performed by processing low and high frequency components of the magnetic field in the operator area.

    摘要： A device for measuring the position (location and orientation), in the six degrees of freedom of receiving antennae (3) with respect to transmitting antennae (2) utilizing pulsed DC magnetic signals. The transmitting and receiving components consist of two or more transmitting antennae of known location and orientation with respect to each other. The transmitting antenna (2) are driven one at a time (or in the case of three or more antennae one or two at a time) by a pulsed, direct current signal. The receiving antennae (3) measure the transmitted direct current magnetic fields and the earth's magnetic field. A computer (5) is used to control the transmitting and receiving elements and to convert the received signals into location and orientation outputs.

    摘要： There is disclosed two helmet systems, each comprising a helmet (11) and, carried by the helmet (11), an optical arrangement (13). In each system, the optical arrangement (13) both provides a collimated display superimposed on the helmet wearer's view of the forward scene through an eyeplece (15 or 50) of the arrangement (13), and senses the angular position of that eye of the helmet wearer looking through the eyepiece (15 or 50) with respect to helmet axes. The optical arrangement (13) senses such angular position by sensing the position, within a sensing area of a sensor (37 or 72), of the point focus of infra-red radiation, from an infra-red point source (35 or 71A), reflected by the eye, and producing an electrical output representative of this position. in one helmet system the eyepiece (15) is of the open optics type and in the other the eyepiece (50) is of the solid optics type.
