ARCore, also known as Google Play Services for AR, is a software development kit developed by Google that allows for augmented reality (AR) applications to be built. ARCore has been integrated into a multitude of devices.[2]

Key technologies

[edit]

ARCore uses a few key technologies to integrate virtual content with the real world as seen through the camera of a smartphone or tablet.[3] Each of these technologies can be utilized by developers to create a high-quality, immersive AR experience.

Six degrees of freedom

[edit]

Environmental understanding

[edit]
  • Allows the phone to detect the size and location of flat surfaces - both vertical and horizontal - with feature points.
  • Geometric plane can be calculated based on detected feature points.
  • A scene semantics API is used to gather real-time semantic data about the user's surroundings and uses that data to identify objects and features in view.

Light estimation

[edit]
  • Lighting Estimation API allows the phone to estimate the environment's current lighting conditions and display images accurately in relation to real-world lighting.
    • Lighting cues such as shadows and highlights are used to more immersively display virtual objects.[5]

Depth analysis

[edit]
  • Utilizes the phone's camera to create depth maps, which enable the device to more accurately determine the amount of space between surfaces based on what is captured.[6]
    • In order to properly assess the real world, depth maps are created to measure the amount of space between objects or surfaces.
    • A depth-from-motion algorithm takes the motion data from the user's camera and utilizes it to create a more detailed depth map.[7]

Geospatial capabilities

[edit]
  • This function's API uses GPS and allows creators to give users unique experiences based on their real-world location.[8]
    • Google's visual positioning system (VPS) is utilized for this process.
  • Matches the user's visual data with that of Google Maps to determine precise location.
