Augmented reality on the iPhone using NyARToolkit [w/ code]

Hi I saw the stats for the blog a while ago and it seems that the augmented reality topic is hot! 400 clicks/day, that’s awesome! So I wanted to share with you my latest development in this field – cross compiling the AR app to the iPhone. A job that proved easier than I originally […]

Augmented Reality with NyARToolkit, OpenCV & OpenGL

Hi I have been playing around with NyARToolkit’s CPP implementation in the last week, and I got some nice results. I tried to keep it as “casual” as I could and not get into the crevices of every library, instead, I wanted to get results and fast. First, NyARToolkit is a derivative of the wonderful […]

Bootstrapping planar AR and tracking without markers [w/code]

Years ago I wanted to implement PTAM. I was young and naïve 🙂 Well I got a few moments to spare on a recent sleepless night, and I set out to implement the basic bootstrapping step of initializing a map with a planar object – no known markers needed, and then tracking it for augmented […]

20-lines AR in OpenCV [w/code]

Hi, Just wanted to share a bit of code using OpenCV’s camera extrinsic parameters recovery, camera position and rotation – solvePnP (or it’s C counterpart cvFindExtrinsicCameraParams2). I wanted to get a simple planar object surface recovery for augmented reality, but without using any of the AR libraries, rather dig into some OpenCV and OpenGL code. […]

Implementing PTAM: stereo, tracking and pose estimation for AR with OpenCV [w/ code]

Hi Been working hard at a project for school the past month, implementing one of the more interesting works I’ve seen in the AR arena: Parallel Tracking and Mapping (PTAM) [PDF]. This is a work by George Klein [homepage] and David Murray from Oxford university, presented in ISMAR 2007. When I first saw it on […]

Never fear – the links are here [Links of the week]

Hi Stuff I picked up on the web the last week: Compare the leading smartphones on the market Mobile web usage stats: iPhone 65%, Android 12%, RIM 9% A transparent screen – Cool? yes. Practical? Not so much. Augmented reality is officially more popular than virtual reality. You don’t need […]
