According to another news source, Stanford University researchers are working on a system that could lead to significant improvements in smartphone cameras.
Image sensors will be able to measure the distance between objects using light as a result of the changes, allowing for 3D images on smartphones.
Lidar, which stands for “light detection and range,” would be required to accomplish this.
Cheaper version of Lidar
Lidar fires a laser beam and multiplies the time it takes to jump off a subject and back to the phone. It can be used to determine how fast an object is moving, how far it is away, whether it is getting closer or farther away, and whether it will collide with another object.
Lidar is already used to improve focus in low light and for night mode on the iPhone 13 Pro and iPhone 13 Pro Max.
Lidar is used in the iPhone 13 Pro models to improve low-light photography.
Stanford’s version of lidar is less expensive than Apple’s, potentially allowing this system to be used on a larger number of handsets. Stanford is working to develop a megapixel-resolution lidar, which is currently unavailable.
Lidar would be able to identify targets in a larger area with the higher resolution. A paper describing the system was written by Okan Atalar, a PhD candidate in Electrical Engineering at Stanford University.
Existing 3D cameras need specialized pixels, which are difficult to realize in large formats and have smaller filling factors due to the complex electronics required to capture 3D in pixels. Our approach converts standard and highly advanced 2D sensors for 3D sensors as opposed to building them from scratch.— Okan Atalar, PhD candidate in Electrical Engineering, Stanford University
Lidar can help in determining an image’s depth. A 3D model can be created by combining multiple images captured by a camera from various angles around a subject.
Uplift Labs examines 3D images to help athletes improve their shape and technique. Sukemasa Kabayama, the company’s CEO, claims that the cameras it uses aren’t specifically 3D cameras.
Sport is an area where smartphones can benefit greatly from 3D imaging and analytics.
If bringing 3D features to smartphones lowers the cost of using 3D technology, everyday athletes will have access to the same harm-reduction data as professionals.
3D will improve security
With 3D cameras, one would be able to capture scenes and objects that people at a distance could experience as if they were physically in space. This would be groundbreaking for remote work, learning and for safe distances during pandemics, as well as for the diagnosis, treatment and repair of functions in the health, technology and manufacturing sectors.— Hans Hansen, CEO, Brand 3D
In terms of security, 3D on smartphone cameras can be a big plus. Because of its 3D mapping, Apple’s True Depth camera makes Face ID more secure than regular face recognition
When scanning a user’s face, the newer 3D cameras on the market should be able to collect even more detailed information, making face recognition systems more secure.
More data about your face is sent to your phone when you collect more detailed information. This should reduce the number of times face recognition fails to recognize your face, as well as protect you from intruders attempting to gain access to your phone.
