FR2782174A1 - STEREOSCOPIC PILOTAGE ASSISTANCE - Google Patents

Abstract

We offer assistance with stereoscopic steering. Using this assistance, sensor images and symbolic monochrome or color, in two or three dimensions, can be represented as information combined in a vision or piloting helmet, and reproduce a stereoscopic representation in three dimensions in true greatness. A particular image exists for each eye, and the information from a symbol generator and electronics appears on a right or left display and is projected by a beam splitter on the right or left eye.

Description

The present invention relates to a piloting assistance device

stereoscopic with a display

three-dimensional images.

  In headset display systems,

  integrated, current, the state of the art relates to the most different embodiments. These are image channels

  binoculars with two separate systems which, without additional means

  such as LCD shutters, polaris

  or red / green separation, allow a good stereoscopic representation of the image. In most

  embodiments, three-dimensional information is represented

  radar and ladar sensors only in one

  two-dimensional representation. In addition, the images of the cap-

  teurs are partly covered by the driving symbols

of flight and armament.

  Document DE-37 12 170 A1 describes a stereoscopic display system according to which stereoscopy is

  obtained by a complicated design with magnifying glasses

  glage, lenses and other optical components. This mode

  was neither envisaged nor designed to be used

dried up on planes.

  Document US 3,833,300 describes a helmet display device with three-dimensional vision for the tracking of a weapon trajectory; in this device, we have

  nevertheless a representation of two-dimensional sensor images

  tional and their combination with a 3D symbolism is not suitable.

  According to document US 4,952,024, there is known an ap-

  similar three-dimensional helmet display for individual use with two image generators; however, this is not intended to be used for, or designed to be used for, stereoscopic steering assistance; it lacks for example the possibility of transparency as well as that of displaying the scene which takes place in front of the user, the switch to two-dimensional image sensors and

  the use of a pursuit helmet.

  The present invention aims to develop

  three-dimensional stereoscopic steering assistance

  starting from an existing viewing helmet and which is modified to allow the representation of images

  monochrome or two- or three-dimensional color sensors

  sions and symbols as combined information in the helmet viewing and steering device as well as a three-dimensional representation; the representation of aircraft landing data is decoupled from the momentary head holding and all sensor information

  are perceived intuitively, i.e. without inter-

predation, nor mental restraint.

  To this end, the invention relates to a device of the type defined above, characterized in that: - a right and left display installation represents non-decoupled stereoscopic information,

  - a symbol generator displays a stereosco- symbolism

  bites according to the position information entered, the helmet angle information and the information from other systems of the control device,

  - an electronic circuit receives information from a system

  frame and symbol generator and controls the left display installation and the right display installation to form at least one information image of the sensor, - the electronics calculate the images for the left eye and

  the right eye independently and the information af-

  plugged in by the left and right display facility project information through the beam splitter into the left or right eye,

  - the view of the user in or before the scene placed from-

before it is guaranteed.

  According to other advantageous features of the invention: - the left display device and the device

  display panels reproduce bi-

  color directional and monochromatic or sym-

boles or other sensor images,

  - frames and / or images are displayed in the layout

  left display device and right display device, - in the left display installation and the right display installation, two-dimensional sensor images are reproduced and the symbols or three-dimensional synthetic images , - the electronics calculate according to the actual speed of the television standard,

  - the symbol generator and the electronic circuit

  rent a representation of the position data of the flying machine, decoupled and of a head support, instantaneous (tracking device) of the user on

  the left and right display installation.

  The present invention will be described below from

  in more detail using exemplary embodiments

  shown schematically in the accompanying drawings, in the-

  which: - Figure 1 shows the construction and operation of a stereoscopic piloting assistance,

  - Figure 2 is a diagram concerning the main information

  blade in the sensor / symbol cockpit,

  - Figure 3 is a diagram of asymmetric stereoscopy.

  The present invention provides a real re-

  three-dimensional presentation of the image of a known, appropriately designed helmet sighting device used

  for visual piloting of airplanes. For this, for the representation

  sentation, the following information is used which can also be combined: - images of monochrome or color sensors in two or three dimensions (TV, FLIR, Radar, etc.),

  - monochrome or color symbols in two or three dimensions

  sions, - monochrome or dual information display channels

  channels with image amplification tubes (BiV).

  The symbolism is controlled by the helmet tracking device of the aiming device to obtain the following types of representation: secured to the head, - secured to the helmet support,

- decoupled from the controller.

  It should be noted that the three types evo-

  The above can also occur simultaneously. In parallel to this, the track plotter angle signals generate a sensor platform so that the images of

  TV, FLIR or radar sensors correspond to the direc-

wanted.

  Starting from a case viewer

  that, integrated modern, and which fulfills all the requirements of

  two- or three-dimensional image representations, the pre-

  sente invention proposes to direct the video channels of the gener

  image editors via two channels to the video input. A symbol generator 1 generates, according to generally known methods, the signs to be represented and the figures of choice for the pilot's eyes; this one recognizes

  information as in figure 1. The three-dimensional symbolism

  is used during the day by linking with sensor images as well as at night. We can also

  use it only during the day and at dusk.

  FIG. 1 shows an exemplary embodiment of a device for assisting stereoscopic piloting, the structure and operation of which are characterized as follows: With the left eye and the right eye 2, 3, a decoupled display is displayed, the stereoscopic information of the left display device and of the right display device 4, 5. A beam guide projects the information of the sensors and of the symbolism of flight into the left eye 2 and into the right eye 3. The symbol generator 1 generates the

  stereoscopic symbols and transmits them to electrical circuits

  symbols symbols. The sensors can be controlled by a tracking system. They thus provide an image of the direction of view obtained by the tracking device.

helmet.

  An important advantage of the proposed design

  is to have a reproduction of monochrome and color images

  their two-dimensional synthetic images or symbols and sensor images for each eye through a clean image channel, that is to say a binocular set, which creates the

  three-dimensional stereoscopic representation. The separation

  The possibility made of the two areas of the image and symbol sensors allows the elimination of undesirable overlays. Pilot sees between three-dimensional sensor images and the eye, three-dimensional symbols like this

appears in Figure 3.

  In addition, the reproduction of raster and shock images, for example two-dimensional sensor images and three-dimensional symbols or synthetic images

  is made possible because these images are calculated independently

  especially for left eye and right eye in the stereo- system

  electronic scopic with independent calculation for left eye and right eye according to the actual speed of the standard

  television (European, American and Japanese standard).

  In addition, the design proposed to achieve stereoscopy is particularly suitable, since it does not contain any reduction in quality (optical reduction) of the elements. The user easily receives the view in or

  across the stage in front of him and he has a

  intuitive location of the aircraft's flight position,

  tance towards obstacles etc. As already mentioned, the representation of the position data of the aircraft is done

  decoupled from the instantaneous holding of the head. The if-

  are supplied by the three-axis helmet tracker

  (helmet azimuth, helmet elevation, helmet roll).
