All you need to know

A real-time hologram is no longer just a figment of our imagination. A new technology based on artificial intelligence (AI), called tensor holography, could indeed allow its creation. So it can be used for virtual reality, medical imaging, 3D printing, etc.

Using artificial intelligence, scientists now have the ability to quickly create 3D images. Moreover, the holograms produced are not only in color, but also have a realistic appearance. And the best part is that this technology can even work on a smartphone or tablet. New technology could also allow it to be used in Virtual Reality and Augmented Reality HeadphonesAnd in other regions.

Real-time hologram: the origin of technology

This is not the first time that scientists have sought to create 3D images by computer. However, the process required large amounts of calculations, and these operations must be done physical simulation. Therefore, the results are far from satisfactory.

Now, MIT researchers have discovered a tensor polyhedron through many experiments that required powerful computers and a lot of computation. The new method is also effective So it can produce holograms almost instantly, even on poorly performing mobile devices.

Liang Shi, a computer scientist from the Massachusetts Institute of Technology, did not even fail to state that everything was working as required. Charm. The result truly exceeded all expectations of the team. Note that Shi worked alongside Wojciech Matusik, his advisor, Beichen Li of EECS, and with the Computer Science and Artificial Intelligence Laboratory at MIT. There are also former MIT researchers, including Petr Kellnhofer (Stanford University) and Petr Kellnhofer (Facebook).

Real-time hologram: an alternative to current virtual reality

Virtual reality has seen a huge development in recent times. Despite this, VR headsets are not cant yet To get rid of computers and televisions in terms of watching video.

The reason is simple: VR technology can make some users upset Patient. This is mainly due to the effects motion sickness. Thus, eye fatigue and nausea may result.

To avoid this, scientists have sought a solution to take advantage of better 3D visualization. Then they have Reworked For the digital world, it is a technology that is more than 60 years old, and it is nothing but a hologram.

An exceptional representation of the virtual world

L ‘3D image in real time able to provide Outstanding acting From the virtual world that surrounds any user. In addition, it presents a picturesque appearance.

Perspective can also change depending on the file location to the user.

Thanks to the technology, his eyes can even adjust the focal depth, thus focusing on the background and foreground in a manner alternative.

3D image in real time

A large database has been created

The goal of computer-generated holography Optical configuration simulation. However, this process represents a long and difficult work. In fact, for each point in a scene or image, the depths are different and therefore the processes applied to them also differ.

To correct this, scientists have Take a different approach. This consists of allowing the computer to take in the physics itself. By designing a database where more than 4000 pairs of images were created. Every pixel and every color information is associated with an image. These contain information about the depth and color of each pixel.

Then the algorithm immediately goes back to work, learning each pair of images and changing the parameters of its own calculations. Thus, the method is successively improved in its ability to create holograms.

In this database there is also a 3D hologram for each image. It’s about using this data so that the convolutional neural network learns to calculate the best way for it Create 3D holograms from photos.

Note that this new system requires less than 1 megabyte of memory. Can generate up to 60 3D images Color per second at 1080p.

The future of holograms in real time

It has been proven that within a millisecond, 3D imaging can Create holograms from images and deep information. This scientific and technological breakthrough paves the way for 3D holograms in real time and could improve a range of systems. They range from virtual reality to 3D printing. The new system can help immerse VR users in more realistic landscapes, while at the same time Eliminate eye strain Or other side effects of long-term virtual reality use.

In the future, eye tracking technology could be used to speed up the system. According to Yang shi, this would allow Create high-resolution 3D images Only in the areas where the eyes look.

Holograms can also be created taking into account the visual acuity of each person. Thus, glasses-wearing users will not need a special VR headset to fit their visual prescription.

3D holographic imaging can also be done Stimulating the development of 3D printing volumetric; This technique can be faster and more accurate than the traditional layer-by-layer method. In fact, volumetric 3D printing makes it possible to do just that Display the entire 3D pattern at the same time.
