Abstract
The present invention relates to a method for displaying, on an autostereoscopic display system comprising a switchable autostereoscopic display, a composed stereoscopic image providing a 3D rendering to said user with a resolution of N pixels and a 2D image providing a flat rendering to said user at a higher resolution than the composed stereoscopic image.
Claims15
A computer-implemented method for displaying, on an autostereoscopic display system comprising a switchable autostereoscopic display, an image based on a 3D representation of at least one portion of a patient, said switchable autostereoscopic display configured to display at least 2×N pixels and being adapted to be switched between at least one stereoscopic configuration and a monoscopic configuration, said method comprising:
- receiving a 3D representation of at least one portion of a patient;
- determining if the autostereoscopic display is to operate in the stereoscopic configuration or in the monoscopic configuration, and:
- if the autostereoscopic display is determined to operate in the stereoscopic configuration, switching the autostereoscopic display to the stereoscopic configuration, and:
- determining, for each eye of a user, a viewing position of said eye relative to the autostereoscopic display;
- computing a pair of 2D images, each 2D image of the pair of 2D images being computed based on said 3D representation viewed respectively from each viewing position, each 2D image of the pair of 2D images being composed of N pixels;
- creating, using said pair of 2D images, a composed image by combining the pixels of the 2D images of the pair of 2D images;
- displaying said composed image on the autostereoscopic display in the at least one stereoscopic configuration thereby providing a depth rendering of the composed image to said user;
- if the autostereoscopic display is determined to operate in the monoscopic configuration, switching the autostereoscopic display to the monoscopic configuration, and:
- computing a single 2D image composed of 2×N pixels based on said 3D representation;
- displaying the single 2D image on the autostereoscopic display in the monoscopic configuration thereby providing a flat rendering of the at least one portion of the patient to said user at a higher resolution than the composed image.
An autostereoscopic display system comprising:
- a switchable autostereoscopic display configured to display 2×N pixels and able to switch between at least one stereoscopic configuration and a monoscopic configuration;
- an eye tracking system configured for real-time tracking of a viewing position of each eye of a user;
- an input for receiving a 3D representation of at least one portion of a patient;
- a processor configured for:
- computing a pair of images, each image of the pair of images being computed based on said 3D representation viewed respectively from each viewing position, each image of the pair of images being composed of N pixels;
- creating, using said pair of images, a composed image by combining the pixels of the images of the pair of images;
- computing a single 2D image comprising 2×N pixels based on said 3D representation;
- an output configured for:
- displaying the composed image on the autostereoscopic display in the stereoscopic configuration thereby creating a depth rendering of the composed image to said user;
- displaying the single 2D image on the autostereoscopic display in the monoscopic configuration thereby providing a flat rendering to the user at a higher resolution than the composed image.
