Sonys neue AR-Technologie: "Smart AR"

News Roger

Die von Sony heute angekündigte, neue "Smart AR"-Technologie kommt im Gegensatz zur AR-Tech, welche von Nintendo im 3DS eingesetzt wird, völlig ohne AR-Karten oder AR-Marker aus.

ScreenshotSony hat bereits 1994 mit der Entwicklung von AR-Technologien begonnen und setzte diese dann 1998 erstmals im VAIO "PCG-C1" ein.

Die neue "Smart AR" kommmt jetzt erstmals auch ohne Marker-Karten / -Codes aus und erkennt Standard-Objekte wie Fotografien oder Poster. Als Basis dient die von Sony entwickelte "3D Space Recognition"-Technologie.

ScreenshotVon Freitag bis Sonntag präsentieren die Japaner die neue Tech in Tokyo interessierten Besuchern. Schade, dass Japan nicht gerade um die Ecke liegt...

Hier ein Ausschnitt aus der original Pressemeldung:

(1) Object recognition that enables the markerless approach

  AR information can be displayed on the captured image which appears on a device’s screen, including those images that do not have any special markers for AR. This technology is also compatible with image recognition technologies that use conventional markers (such as “CyberCode*2”). Because “SmartAR” can recognize everyday objects such as posters and menus, it has the potential for a wide variety of applications.

  “SmartAR” object recognition technology identifies objects by analyzing features detected from a portion of the image (hereafter, ‘local features’) together with their positional relationship. Our feature matching technology that employs a proprietary probabilistic method that matches local features with minimal calculations enables high-speed recognition that is resistant to changes in lighting or the position of the object. In addition, recognition is still possible even if the object captured appears to be comparatively small in the display.

(2) High-speed tracking (‘rapid & accurate’)

  Sony achieved its natural-feeling ‘rapid & accurate’ AR by quickly displaying AR information on the screen and then tracking the camera’s movements at high-speed. This has been realized by combining object recognition technology with our proprietary matching technology that uses features detected from a portion of the image (‘local features’) and image tracking technology that is capable of dealing with changes in the shape of the object.

(3) 3D space recognition

  With our dynamic, large-scale AR, virtual objects can be merged with 3D structures detected in the physical world. For example, even if the AR image is a gigantic virtual character whose size exceeds the dimensions of the device’s screen, the technology allows the user to grasp the entirety of the virtual character when the camera is moved around. Furthermore, it is also possible to move the virtual object in the actual 3D space as if it were really there.

  Three-dimensional space recognition technology is based on use of the disparity observed by the camera movements to estimate the shape of the 3D space and the position and angle of the camera. By combining this with object recognition technology, devices become capable of identifying and remembering 3D space constructions.

(4) AR Interaction

  Information can be intuitively acquired and navigated by directly touching the AR information displayed on the smartphone or device’s screen. The distinctiveness of “SmartAR” technology comes from the user interface which enables users to naturally use and operate additional information and virtual objects.
