Japanese telecommunication corporation NTT has unveiled innovative technology that allows the creation of volumetric 3D images without the need for special glasses or direct screens. Traditionally, a major challenge in implementing augmented reality was the difficulty of accurately calibrating equipment to display images. The use of composite displays made up of multiple screens often resulted in inconsistencies and image tears due to the gaps between screens.
NTT researchers took note of the human brain’s ability to “fill in” missing parts of an image based on partial information, known as the “transparency of perception” effect. An example of this phenomenon is the Kanizsa triangle, where fragments of an image are interpreted by the brain as forming a complete triangle.
The researchers leveraged this perceptual effect to develop a technology for displaying 3D images in public spaces without the need for direct viewing or augmented reality headsets. They achieved this by breaking down the original 3D image into fragments and displaying these fragments on randomly positioned displays of various types and sizes. This approach differs from the traditional grid-based approach and instead uses an arbitrary configuration.
However, simply randomly placing monitors is not sufficient for the system to function correctly. The system requires thorough calibration, with a two-dimensional code displayed on each monitor for spatial analysis. Images are then captured to assess the “spatial location of the monitors,” with the option to use one or two cameras for a more accurate depth evaluation.
