ARCore and Arkit, What is under the hood: SLAM (Part 2)

In our last blog post ( part 1 ), we took a look at how algorithms detect keypoints in camera images. These form the basis of our world tracking and environment recognition. But for Mixed Reality, that alone is not enough. We have to be able to calculate the 3d position in the real world. It is often calculated by the spatial distance between itself and multiple keypoints. This is often called Simultaneous Localization and Mapping (SLAM). And this is what is responsible for all the world tracking we see in ARCore/ARKit. What we will cover today: How ARCore and ARKit does it's SLAM/Visual Inertia Odometry Can we D.I.Y our own SLAM with reasonable accuracy to understand the process better Sensing the world: as a computer When we start any augmented reality application in mobile or elsewhere, the first thing it tries to do is to detect a plane. When you first start any MR app in ARKit, ARCore, the system doesn't know anything about the surroundings. It starts pro

ARCore and Arkit: What is under the hood : Anchors and World Mapping (Part 1)

Reading Time: 7 MIn Some of you know I have been recently experimenting a bit more with WebXR than a WebVR and when we talk about mobile Mixed Reality, ARkit and ARCore is something which plays a pivotal role to map and understand the environment inside our applications. I am planning to write a series of blog posts on how you can start developing WebXR applications now and play with them starting with the basics and then going on to using different features of it. But before that, I planned to pen down this series of how actually the "world mapping" works in arcore and arkit. So that we have a better understanding of the Mixed Reality capabilities of the devices we will be working with. Mapping: feature detection and anchors Creating apps that work seamlessly with arcore/kit requires a little bit of knowledge about the algorithms that work in the back and that involves knowing about Anchors. What are anchors: Anchors are your virtual markers in the real wo

IRCTC blocking certain countries?

Indian Railway Catering and Tourism Corporation or most commonly known as IRCTC is the only authorized government portal in India through which someone can book a Train Ticket. It also provides booking for flights and buses but its primary use for most people is to book rail tickets online. And like thousands of other people I also use the site intermittently while booking train tickets, especially for my parents who are in India and when I want to book tickets for them. A few days back they asked me to book a ticket for them and that is when the fun started. I found out that when I tried to access the website day before yesterday (4th July 2018), instead of the familiar login page I was greeted with an error that page cannot be loaded. I thought maybe something wrong and I would try later. After a day I tried and faced the same error. Now a little bit curious since I actually never seen the site down for a prolonged time, blamed it on my Comcast connection and connecte
