This is my first time working on Augmented Reality topic. I am about to develop an application which uses augmented reality to recognise and measure the n number of objects in my room. Something like in the attached image. I need to identify each edges and corners and have to do some vast math calculation for the measurement. I am pretty sure that it cant be achieved only through iOS SDK, I need to use some external library/SDKs. I need some scanner SDK which does the real time image recognition.
I came across Qualcomm's Vuforia, Realitycap, metaIO. My dilemma is, a developer who worked in product and business based iOS application can do this image recognition stuff? An iOS developer does not have that awesome experience in image processing. Can anyone suggest me some cool stuff to come over? Suggest some ideas also, it will help me a lot.
You can use metaio sdk to scan different objects. You can create as many object models in unity3D and have in database. The above sdk helps you to do in 3D scanning and many more features.
I think there is a possibility to use OpenCV
API can be found at: http://opencv.org

I need to develop a prototype of an augmented reality app for research purpose.
This is my first time with augmented application and I only have basic knowledge on android.
The application is an android application that uses video overlay to display over the scene after detecting a target. The only problem is that the videos are obtained from another user (through another application that will allow user to record a video). The tutorials and examples I found allow you to attach the video to the target by developer not the the user and that's not my case.
Since either way I have to invest sometime to learn how to develop it. Whats you recommended environment? Android studio with **Vuforia. Vuforia with unity ? or other SDK? and I would appreciate if you have a slimier tutorial and samples.
It just a prototype therefore I'm not looking for high quality. Easy and less time consuming is my interest.
Unity 3D with Vuforia is easier for a beginner to understand. For more advanced functions you might want to use the Android Studio. I am not sure about how the user can attach a video to the target since normally, the developer has to include the video file in the Assets folder to attach it to target. This is how it is done in Unity. I hope someone can give you a better insight into this. But, I have worked with Unity/Vuforia and it is a pretty comfortable and easy environment for a beginner. All the best for your prototype :)

I have a 3D object displayed on the iPhone screen, I need to display it via VR glasses and the user can interact with the object (zoom in/out).
-I need help how doing this using VR glasses without using unity.
Thanks
If you don't want to use Unity, then you will have to roll this out mostly on your own. There are some example projects that show how to create basic VR experiences on iOS (including one I made using SceneKit).
If you want to make something more serious, and are not looking to just experiment, then I'd highly recommend using Unity since you can then use the latest Google Cardboard SDK. This will give you much better results since it will handle all of the camera/view aspects for you.
You can use a Google Cardboard for you headset, at least that is an initial inexpensive option. There is a magnetic "trigger" on the Cardboard that you can use for binary input in you app. My example project also includes a class that handles input from this trigger by detecting the disruption to the magnetic field around the device's compass. You can use this trigger to handle the zoom in/out.
Good luck!

I am creating an iPad app for golfers, I will get their score card image as below. I want to calculate sum of scores for each person by scanning this image.
Is there any way. Please give me a logic for this.
I have used opencv http://opencv.org in the past to do something similar but with sudoku puzzles.
It is a LOT of work and making it work with handwriting will add to the difficulty.
I found a really good resource for analysing sudoku grids. I'll try to find it again but it was 4 years ago.
Good luck though.
There is a Tesseract port for iOS which is about the best OCR you're likely to get on the platform without either:
A) Porting another OCR library
or
B) Shipping the images off to an online OCR service
To make this more complex, you don't just want to OCR but you want to OCR handwriting and put it into a grid. This is not something that can be done overnight but is in fact rather complex. Not impossible, but complex.
Would it not just be easier to let the players enter there scores straight onto the app and then airprint a score card?

I apologise in advance for my ignorance :)
I'm a n00b to iOS development, but have experience in Ruby. I really want to learn how to develop games such as endless runners and 3d games in general such as Subway surfers.
So far from my research i've gathered that I will need to learn objective-C and learn how to operate Unity3d. As there is so much conflicting information out there i'm struggling to establish where to start as i do not wish to waste time.
So if someone could create a linear list of steps that i could take to start my game development journey I would be ever so grateful.
Thank you. JB.
you can create games through the unity 3d. it does not requires learn objective C language. if you are already familiar with the C# then it is enough for this. unity 3D requires scripting.it is cross platform engine
Antiryad Gx :it is another one game engine.it also does not requires objective C. if you are already familiar with c, C++ then it is enough for create 3d for ios. it is cross platform engine.
BatteryTech SDK:based on c++.
Cocos3d: it is sophisticated 3D application development framework for the iOS platform. With cocos3d, you can build sophisticated, dynamic 3D games and applications using Objective-C.
visit this link, it has list of game engines in which you can check for the language you are familiar. by this way ,you can save time of learnng new language& directly concentrate on game development

How suitable RubyMotion for iOS game development?
I was not able to find CoreAnimation topics in documentation, but as I've heard someone was able to use cocos-2d with RubyMotion.
If you have some useful information which you are willing to share, I would greatly appreciate this!
If you are willing to program your game completely programmatically, RubyMotion is a fine choice. There is no appreciable drop in performance and every C library and API is available to RubyMotion. Using motion-cocoapods you're even able to include CocoaPods and you can also include Objective-C libraries.
The one issue you may run into is a lack of RubyMotion-specific tutorials and documentation for games.
EDIT: I successfully (with help) recreated the Sparrow game engine demo in RubyMotion:
https://github.com/jamonholmgren/demo-sparrow
It runs beautifully.
You can try JoyBox it combines popular 2D game engine for iOS, Cocos2D, folds in with Box2D physics engine, and wraps into Ruby API. Joybox can be found at this link on github.
