Abstract

Rückprojektion von 360° Dome Kamera Aufnahmen (2) auf eine dreidimensionale Kuppelprojektionsfläche (1). Dadurch gekennzeichnet, dass der Projektor (7) das Rundbild (2) mittels Fisheye-Objektiv (2) auf die Projektionskuppel (3 und 4) projiziert.Rear projection of 360 ° dome camera images (2) on a three-dimensional dome projection surface (1). Characterized in that the projector (7) the round image (2) by means of fisheye lens (2) on the projection dome (3 and 4) projected.

Description

Technische Beschreibungtechnical description

360° Dome Projektor (1) für die Wiedergabe von Aufnahmen, welche mittels 360° Dome Kameras erzeugt wurden.360 ° Dome projector ( 1 ) for the playback of recordings made with 360 ° dome cameras.

360° Dome Kameras verdrängen im Bereich Indoor-Videoüberwachung immer häufiger die herkömmlichen Überwachungskameras. Dome Kameras erfassen in jedem Einzelbild eine komplette Raumansicht. Per Software lassen sich einzelne Bereiche des Raumes innerhalb des Rundbildes auswählen. Nur diese Bereiche werden für das Überwachungsbild entzerrt. Dadurch kann eine einzige Kamera mehrere verschiedene Bereiche in einem Raum überwachen.360 ° dome cameras are increasingly replacing conventional surveillance cameras in indoor video surveillance. Dome cameras capture a complete room view in each single image. Software can be used to select individual areas of the room within the circular image. Only these areas are equalized for the surveillance image. This allows a single camera to monitor several different areas in a room.

Stand der Technik zur Verwendung der Aufnahmen von 360° Dome Kameras:State of the art for using the images of 360 ° dome cameras:

Die mit 360° Dome Kameras erstellten Bilder oder Filme werden ausschnittsweise für die Wiedergabe auf einem herkömmlichen, flachen Bildschirmen mittels Software entzerrt (Unwrapper-Software). Die (Teil-)Wiedergabe der 360° Filme auf einem flachen Bildschirm lässt das Potential der 360° Aufnahmen jedoch lediglich erahnen.The images or films created with 360 ° Dome cameras are partially extracted by software for playback on a conventional, flat screen (Unwrapper software). However, the (partial) playback of the 360 ° films on a flat screen only gives an idea of the potential of the 360 ° shots.

Für die Übersicht auf die gesamte 360° Ansicht wäre die Wiedergabe der Aufnahmen von 360° Dome Kameras in dreidimensionaler Kuppelform ideal.For the overview of the entire 360 ° view, the reproduction of the images of 360 ° dome cameras in a three-dimensional dome shape would be ideal.

Problemstellung:Problem:

Es gibt bisher keinen kuppel- oder halbkugelförmigen 360° Bildschirm oder eine anderweitige 360° Projektionsfläche, welche die 360° Dome Aufnahmen darstellen könnte.So far there is no dome or hemispherical 360 ° screen or any other 360 ° projection screen that could represent the 360 ° dome shots.

Diese Probleme werden mit den in den Schutzansprüchen 1–2 aufgeführten Merkmalen gelöst.These problems are solved with the features listed in the protection claims 1-2.

Der 360° Dome Projektor (1) bietet erstmals eine echte 360° Darstellung für die mit 360° Dome Kameras erzeugten Bilder oder Filme. Der 360° Dome Projektor projiziert über ein 360° Fisheye-Objektiv (2) den für die 360° Darstellung optimierten Strahlengang auf das Rückprojektions-Kuppeldisplay. Der Betrachter sieht auf dem 360° Kuppeldisplay ein natürliches und absolut nahtloses 360° Bild oder einen 360° Film.The 360 ° Dome Projector ( 1 ) offers for the first time a true 360 ° display for the images or films created with 360 ° dome cameras. The 360 ° Dome projector projects via a 360 ° fisheye lens ( 2 ) optimized for the 360 ° representation beam path on the rear projection dome display. The viewer sees on the 360 ° dome display a natural and absolutely seamless 360 ° image or a 360 ° film.

Mit der Erfindung wird erreicht, dass die 360° Filme auch tatsächlich in realen 360 Grad wiedergegeben werden. Der Betrachter kann die 360 Grad Projektion vollständig umrunden. Es gibt hierbei keine Nahtstelle des Bildes auf der 360° Projektionsfläche.With the invention it is achieved that the 360 ° films are actually reproduced in real 360 degrees. The viewer can completely circle the 360 degree projection. There is no seam of the image on the 360 ° projection surface.

Die mit 360° Dome Kameras aufgezeichneten Rundbilder und Donutmovies (2) können ohne weitere Bearbeitung direkt mit dem 360° Dome Projektor (1) dargestellt werden. Hierzu wird die originale 360° Rundaufnahme der Dome Kamera (2) per SD-Speicherkarte oder USB-Stick auf den 360° Dome Projektor (1) übertragen. Der im Projektor integrierte Mediaplayer projiziert die Bilder und Videos auf die Projektionskuppel (3 und 4).The 360 ° dome cameras recorded circular images and donut movies ( 2 ) can be directly connected to the 360 ° Dome 1 ) being represented. For this, the original 360 ° round dome camera ( 2 ) via SD memory card or USB stick to the 360 ° Dome projector ( 1 ) transfer. The media player integrated in the projector projects the pictures and videos onto the projection dome ( 3 and 4 ).
