Hemispherical digital camera inspired by bug’s eye for 180-degree snap
Research held at University of Illinois at Urbana-Champaign and Northwestern University had led to the development of hemispherical digital camera. This peculiar camera contains nearly 200 tiny lenses which deliver an exceptional wide- angle field of view with sharp images.
This camera is very much similar to that of fly eye as it is a rounded half bubble. It has 180 microlenses on it and these allow taking pictures nearly 180 degree.
This new technology can also be used for endoscopic imaging. The researchers say that it would be very easy to get 360-degree view by combining two hemispheres. Each small eye consist of microlens and microscale photodetector, which itself have a separate imaging system. And this helps in having a clear 180-degree snap.
As per the research. each microlens develop a small portion of the entire object with the help of the viewing angle. an individual detector respond if and only if the portion of the image thus formed by the consecutive lens will overlap. The detector stimulated will produce a sample image of the original object. Thus one can get a beautiful, detailed, 180-degree snap.
Ever since ChatGPT hyped the use of AI, everyone wanted to try similar AI models on their devices for daily queries. These are powerful AI models capable of executing high-level tasks. Now with the help of customized tools, users can install various Large Language Models (LLMs) on their computers for offline use. If you want to make your computer an AI chat tool that you can access anytime you want, then the answer is the tool that allows users to install various AI models such as Llama 3, Phi 3, Falcon, Gemma, Replit, and more. Let’s now see the steps to get these tools and setup AI Models. M inimum Requirements: Apple Silicon Mac (M1/M2/M3) with macOS 13.6 or newer Windows / Linux PC with a processor that supports AVX2 (typically newer PCs) 16GB+ of RAM is recommended. For PCs, 6GB+ of VRAM is recommended NVIDIA/AMD GPUs supported Note: You can follow this guide for Windows, Mac, and Linux platforms. AI Models use a high amount of RAM, CPU, and GPU. I...
It’s a good way to see the world. Representative image. Image by Greg Rakozy on Unsplashed In the ‘biggest update to Google Earth since 2017,’ Google has added the new Time-lapse feature. Time-lapse in Google Earth combines 24 million satellite photos from the past 37 years to make a 4D interactive model. As the name suggests, the Google Earth Time-lapse feature lets you go through a time-lapse of how things have changed over the years. Time-lapse in Google Earth consists of photos taken from 1984 to 2020, which equals 20 petabytes (1 Petabyte is one million gigabytes) of satellite images. Google took these pictures and stitched them into a 4.4 terapixel video. The company says that this entire video is equivalent to over 5 million 4K resolution videos. That said, Google is also calling Time-lapse on Google Earth the largest video on the planet. In its blog post , the company has also promised annual updates to Google Earth for the nex...
Google’s Project Jacquard Turns Clothes Into Touch Screens and Track pad We are currently breathing in a world that is smarter. We have smart phones, smart tabs, smart televisions, smart watches and what not but there’s one thing that Google wishes to add to this list of smart things of our everyday life. Want to know about it – its smart fabric, a fabric inbuilt with sensors, equipped with the ability to sense touch, swipe, send data through the conductive yarns and lot more. This is an effort by Google to generate a technology that would revolutionize the field of textiles and fabrics. The fabric can also facilitate calling, messaging, chatting and lot more alike. The project named as Project Jacquard debuted on Google I/O 2015 as a unit of Google ATAP. The fabric is weaved with a special yarn that is conductive created by Google ATAP team in partnership with American jeans manufacturing company Levis. However, the fabrics are not fully weaved out of the ...
