Okan Atalar, a graduate of Bilkent University’s Department of Electrical and Electronic Engineering, started his PhD in Electrical Engineering at Stanford University in the United States in 2016.
For the last 4 years, Atalar has been in the United States, R&D studies carried out by 3 scientists, one Belgian and two Americans, from the same university, in order to add a low cost “depth axis” to a existing camera, gave results.
The article on the invention of Okan Atalar and the scientists he works with, which makes it possible to take photographs and images in three dimensions, was published in the International Journal of Nature, which includes the best studies evaluated by peers in science and technology. .
The biggest flaw is that the distance axis cannot be added to cheap sensors.
Atalar made a statement to the AA Correspondent regarding the new technology which will have an impact in the scientific world.
Affirming that these studies have generated great interest in recent years and that many technologies and research have been carried out around the world on this subject, Atalar explained that these studies focus on the ability of robots and unmanned vehicles to move. safely in a dynamic environment and perceive their environment very well.
Atalar noted the following regarding the shortcomings of these studies:
“This detection is currently possible with special cameras and optical sensor systems, but the biggest flaw of current systems is that the distance axis cannot be added with cheap sensors. Since the human brain is very sophisticated, we can perceive the environment very well through our eyes, but it’s not easy for a robot to do so. Its brain is good at detecting distance from two-dimensional images, but it’s very difficult to do for a robot. Additionally, measuring the depth axis will enable performance in cameras beyond human vision.
Another important application area of the depth axis is virtual and augmented reality. There is currently a lot of work in the world to develop efficient, effective and inexpensive sensors capable of measuring the dimension of depth.
Existing systems still fail to detect the third dimension
Atalar said that although the performance of existing optical systems capable of measuring depth with cameras is very low, they require a high cost and that they have created a simple device that can be added to an existing camera after 4 years of work.
Pointing out that existing mobile phone cameras show very successful results in light and color detection, they still perform quite poorly in third dimension detection, Atalar pointed out that third dimension detection is possible with special optical systems, but they are far behind standard cameras in terms of performance and price.
“The main reason for this was that the low-power, high-performance optical components needed to give mobile phones the third dimension could not be invented.” Okan Atalar gave the following information about the technology they developed:
“We have invented a special optical device that can be integrated into an existing camera. What makes this device special is that it is very inexpensive. There is no such technology available on the market for the moment, and an optical device that allows depth perception consumes 100, maybe 1000 times more energy than a camera. In our device, on the other hand, depth perception can be obtained with an energy very low, very cheap and very powerful.With this system, when a photo is taken, the brightness and color of the light and its distance can be seen in each pixel.The technology we have developed will advance the virtual and augmented reality and the metaverse universe, and will improve its performance.”
Easy to integrate and works with low battery level
While explaining the principle of operation of the system, Atalar said that they integrated a simple light source and an optical device into a normal camera and said: “The device that we showed worked in the prototype the highest performance in the world. , is easy to integrate and works with the lowest battery level. ” mentioned.
Okan Atalar said that after their technology was published in Nature Magazine, investors and research institutes in Silicon Valley called them and made an investment offer. Atalar said: “We are still at the stage of deciding on the best use of the technology. We thought about this technology for robots and smartphones, but it can also be used in infrared cameras. So it is possible to capture the depth axis by making simple integration with any camera.” he said.
