Vuforia Camera Bridge

Vuforia Camera Bridge is an adapter interface to enable Vuforia apps installed on UWP devices to access external cameras that do not fall within Vuforia Engine’s supported camera devices. The Camera Bridge is available for Windows machines as a standalone executable.

Vuforia Engine supports most generic webcams through Windows’ Media Foundation API. The Vuforia Camera Bridge gives you access to specialized cameras with custom device drivers, often used in industrial settings. Such cameras use the DirectShow camera API or other APIs for camera access.

Get the Vuforia Camera Bridge executable and the complete guide in the README.md from the Downloads External Camera section.

Use Cases

The Vuforia Camera Bridge is meant for use cases where a custom Vuforia Driver, which is based on the Vuforia Driver Framework, would not work, as the driver would run in the same restricted sandboxed environment (Windows Runtime) as the app itself.

The Vuforia Camera Bridge lets you gain access to cameras using the DirectShow API or other vendor specific APIs from within the Windows Runtime sandbox.

You can also use the Vuforia Camera Bridge with existing Vuforia UWP apps and external cameras.

Prerequisites

The Vuforia Camera Bridge is supported on Windows 11 x64 version 21H2 / 10.0.22000 or newer.

The Vuforia Camera Bridge is backwards compatible with apps that use earlier versions of Vuforia Engine. But only apps that use Vuforia Engine 10.18 and newer support passing custom camera intrinsics with this tool.

Installation and configuration

The Vuforia Camera Bridge is available as an installable MSI package.

Please refer to the README.md available in the downloadable package for installation and configuration instructions.

Camera Intrinsics

Pass custom camera intrinsics with the Vuforia Camera Bridge to your app. Use a JSON file with a set of parameters. See Using External Cameras with UWP for the intrinsics parameters and the README.md for the Camera Bridge configurations instructions.

For getting camera intrinsics from your camera, see External Camera Calibration.

Custom Development

The Vuforia Camera Bridge is open source to support cameras with vendor specific APIs. To build and run a customized version of the Vuforia Camera Bridge MSI package, please refer to the README.md Development section.
