Build Image Tracking Augmented Reality app in Unity & C#

Discover how to set up Unity with Unity Hub, install the editor, and choose latest or long-term support versions for AR and VR projects.

Select an image with distinct variation to serve as the tracking target, then capture a video and use its first frame as the target to render video on the iPhone.

Create a new unity project in unity hub with the universal render pipeline, then switch the build target to ios and set the mobile render pipeline for development.

Install AR Foundation, ARKit, and ARCore in Unity to enable cross-platform augmented reality development. Configure the package manager, plugins, and render pipeline for iOS and Android testing.

Set up a fresh Unity scene for an image-tracking augmented reality app, configuring the XR origin, main camera, input manager, and image-tracking components, and testing camera access.

Set up image tracking in Unity using the tracked image manager, serialized library, and reference image library to track multiple targets and render the track image prefab.

Create image-tracking video prefab in Unity by building an empty controller, a sized holder cube, a transparent material, and a video quad, then save as a prefab for ar use.

Write a Unity C# script to manage image tracking states with a track image manager, instantiate and map prefabs to tracked images, and update their position, rotation, and scale.

Build your Unity image-tracking AR app for iOS or Android, generate an Xcode project or APK, configure build settings, sign automatically, and run on your device.

Test image tracking on mobile by overlaying a video on a tracked image, view it in landscape, and move or minimize the image to see continuous tracking.
