Device, and related method, for determining the direction of a target
First Claim
1. A device capable of determining the direction of a target in a predefined frame of reference and of the type having sighting means (10), means having a sighting member (13), three gyrometers (141, 142,143) arranged along three axes in different planes, means for control (16), means (20) for resetting said sighting means (10) and means (30) for processing signals derived from the sighting means (10), said processing means (30) being capable of determining the direction between the sighting means (10) and the target and of transmitting to imaging means (40) or to external means (50, 60) and also means (16) for controlling the transmission to the imaging means (40) or to external means (50, 60), of representative values of the direction between the sighting means (10) and the target, this device being characterized in that it comprises at least one non gyroscopic sensor (17) arranged on the sighting means (10) and capable to emit a signal for its transmission to the said processing means (30), and in that the processing means are capable of determining a terrestrial frame of reference from the signals derived from the said gyrometers (141, 142,143) and from the said non gyroscopic sensor (17).

Abstract
The invention concerns the field of sighting or aiming means and more particularly a device (1) for determining the direction of a target in a predefined frame and of the type having sighting means (10), means having a sighting member (13), three gyrometers (141, 142, 2143) arranged along three axes in different planes, means for control (16), means (20) for resetting said sighting means (10) and means (30) for processing signals derived from the sighting means (10), said processing means being capable of determining the direction between the sighting means (10) and the target and of transmitting it to imaging means or to external means, and also means (16) for controlling the transmission to the imaging means (40) or to external means, of representative values of the direction between the sighting means (10) and the target, this device being characterized in that the resetting means comprise at least one non gyroscopic sensor (17) arranged on the sighting means (10) and capable of emitting a signal for its transmission to the said processing means.

- 26. The resetting process of the device capable of determining the direction of a target in a predefined frame of reference and of the type having sighting means (10), means having a sighting member (13), three gyrometers (141, 142,143) arranged along three axes in different planes, and having at least one non gyroscopic sensor (17), these elements being capable of emitting a signal for its transmission to the said processing means (30), the processing means (30) being capable of determining the direction between the sighting means (10) and the target, is characterized in that it comprises a stage consisting in determining a terrestrial frame of reference from the signals derived from the said gyrometers (141, 142, 143) and from the said non gyroscopic sensor (17).
- 30. A process as defined in claim 30, which utilizes sighting means composed of an electronic imaging sensor, such as a camera rigidly fastened to the sighting means, this camera generating a signal representative of the image observed, the process being characterized in that it uses a step that makes the imaging process capable of determining the position of a pattern in the said image, the position of this pattern being known.
