Definitions

  • the invention relates to a device and a method for listening by means of acoustic monitoring of at least one Horchsektors, which is located in a monitorable by means of a sonar monitoring level, according to the preamble of claim 1 and 8, respectively.
  • a conventional sonar system is used to locate underwater objects. Locating by means of passive sonar is possible if the object is or has a noise source that emits water sound signals that can be received by the sonar system. With active sonar water sound signals are sent in the direction of an object, reflected by the object and then received by the sonar system.
  • the conventional sonar system has at least one receiving antenna with a multiplicity of water sound receivers, for example electroacoustic transducers, which generate electrical reception signals in response to received water sound signals or water sound waves and provide them to a direction generator.
  • water sound receivers for example electroacoustic transducers
  • the direction generator of the known sonar system generates directional signals from the received signals of the waterborne sound receivers by delaying the received signals for a plurality of main reception directions depending on the transducer location and combining them into group signals or the direction signals. Each directional signal is therefore assigned a main receiving direction.
  • the main receiving direction points in the direction of the maximum reception of the main lobe of a directional characteristic of the sonar. In a horizontally oriented receiving antenna, the main receiving direction denotes a bearing angle in the horizontal plane.
  • the directional signals provided by the direction generator are usually - after further signal processing - provided to a display means for visual presentation, are influenced on the direction signals according to their sound level. If the directional characteristic points to an object or a sound source, the received sound level is greater than the sound levels of adjacent directional characteristics.
  • the known sonar system has an audio signal processing unit which generates a mono audio signal from a direction signal. All direction signals together determine the monitoring level that can be monitored by means of the sonar system, while the direction signal used to form the audio signal or the main reception direction assigned to the direction signal defines an actually acoustically monitored listening sector. The listening sector is thus acoustically reproduced by means of the mono audio signal, whereby a spatial resolution or bearing within the listening sector in the mono audio signal is not possible.
  • US Pat. No. 6,885,612 B2 and DE 15 668 57 A disclose devices which generate a stereo audio signal from a plurality of directional signals by means of suitable signal processing.
  • the listening sector or the monitoring level is acoustically imaged by means of the stereo audio signal such that a spatial resolution or bearing within the listening sector or within the monitoring plane is possible.
  • Means or methods for adjusting the Horchsektors do not show these known devices.
  • a device which has a Schohorchidesseinstellstoff, by means of which a lying in the Horchsektor Haupthorch512 by pivoting against an antenna fixed Reference direction is adjustable. If in this known sonar system only one direction signal determines the listening sector and thus made audible, the Feldhorch512 is identical to the lying in the listening sector main receiving direction.
  • the known Haupthorchidesseinstellstoff is a trackball that can be rotated by an operator, wherein the Haupthorchides shifts and the succession of the different main receiving directions associated signals acoustically, for example.
  • a headphone By means of a headphone, can be played. By listening to sound levels of adjacent directional characteristics thus a noise source can be targeted.
  • the trackball for adjusting the bearing angle is often used in known sonar systems for other purposes, in particular for setting other parameters. It must therefore be switched between different functions of the trackball, which is time consuming and complicated. In addition, it is time consuming to set by means of the trackball successively comparatively far away from each other Stilhorch512en because the trackball this comparatively far has to be rotated, the operator may need several times implement the trackball serving hand. Finally, the mass of the trackball hinders fast and precise navigation between different main horns.
  • the invention is therefore based on the object to improve the setting of the main hearing direction.
  • the invention solves this problem with a device according to claim 1 and with a method according to claim 8.
  • the invention has recognized that the adjustment of the main hearing aid is simplified with a device having a viewing direction detection means by means of which a viewing direction, in particular main viewing direction, of one or both eyes of an operator is detectable, and in which the main body - A -
  • Tungseinstellstoff is formed such that by means of the Haupthorchidess- adjustment means the Haupthorchtechnisch in dependence on the detected line of sight is adjustable.
  • the invention makes use of the fact that the operator can swivel his viewing direction quickly and focus very precisely on a target. As a rule, it makes little or no difference whether the viewing direction is pivoted to a neighboring or more distant target. A pivoting of the viewing direction to a farther away target thereby causes a pivoting of the main horch device to a farther away main hurdle.
  • the operator can adjust an adjacent main direction by means of the line of sight detection means and the main cursor adjusting means substantially as fast as a main direction further away. In any case, a fast, simple and precise adjustment of the main direction is possible.
  • the viewing direction detection means is, for example, a so-called eye tracker, which is preferably arranged stationary relative to the sonar system, but alternatively can also be fixed to the head of the operator or to a device carried on his head. In the latter case, it is advantageous to project an image on which targets are to be selected by detecting the viewing direction on the retina of the operator and to detect, in addition to the viewing direction, a position and orientation of the head in the space in which a target is fixed ,
  • the viewing direction detection means when the viewing direction detection means is arranged stationary in space, the viewing direction detection means must first detect the eye or the eyes of the operator in order to be able to determine the viewing direction based on details of the eye, for example the position of the pupil.
  • Either the line of sight detection means or the eye tracker is aimed specifically at the eye of the operator and is actively readjusted in its orientation when the operator changes his position in the room.
  • an area which is larger than the eye of the operator is optically detected and by means of image processing means first detects the eye in the detected area and then the line of sight.
  • a set main direction is not adjusted in every case when the viewing direction detecting means detects a change in the viewing direction of the operator.
  • the operator is supposed to have the opportunity to focus on other things without the main hurdle being obstructed. Therefore, it can be provided that the main hurdle can only be readjusted if at the same time another operating element, for example a push-button, is actuated.
  • a pattern may be detected after the gaze direction changes in a given time and / or is directed to a particular destination, the device only in response to such a known pattern restores the main orchestration. For example, after having previously focused his gaze on a particular target for a predetermined period of time, the operator subsequently causes the gaze to be adjusted to a predetermined confirmation target or blinks or gazes at a particular pattern. Alternatively, the longer fixing of a target for adjusting the main direction may be sufficient and a simultaneous or subsequent confirmation or input omitted.

  • the sonar system can have more than one direction generator and / or more than one audio signal processing unit, so that the invention is not limited to use in sonar systems with only one single directional device or a single audio signal processing unit. If the sonar system according to the claims "has a" direction generator or “an” audio signal processing unit, then “a” or “one” is thus not to be understood as a number word but as an indefinite article. Overall, the invention makes it possible to quickly and inexpensively locate different objects or sound sources in the water. The operator does not need to use his hands to set the main direction and therefore has his hands free for other tasks. The trackball can also be used for other tasks.
