Orbbec SDK DotNet Wrapper

This is a wrapper for the Orbbec SDK for DotNet. It supports .NET 8.0 and later versions, and is compatible with Windows and Linux platforms.

It provides a simple and easy-to-use interface for accessing the Orbbec camera and performing various operations such as capturing depth images, color images, and performing point cloud generation.

The v2-main branch is based the open source version of Orbbec SDK v2.

If you need to use .NET Framework, please use this repository. However, .NET Framework is maintained for bug fixes only, and no new features will be added. We recommend using Orbbec SDK DotNet Wrapper instead.

• Windows: Windows 10 (x64), tested with .NET 8

• Linux x64: Tested on Ubuntu 20.04, 22.04, and 24.04, with .NET 8

Environment Setup

Please refer to this document for compilation instructions.

windows

For windows, you need to register the metadata associated with frames (this includes things like timestamps and other information about the video frame).

• Metadata registration follow this:/scripts/obsensor_metadata_win10.md

Notes: If the metadata is not registered, the device timestamp will be abnormal, thereby affecting the SDK’s internal frame synchronization functionality.

Linux

For Linux, we have provided a script to help you set up the environment. You can run the script as follows:

cd scripts
  sudo chmod +x ./install_udev_rules.sh
  sudo ./install_udev_rules.sh
  sudo udevadm control --reload && sudo udevadm trigger

Notes: If this script is not executed, open the device will fail due to permission issues. You need to run the sample with sudo (administrator privileges).

How to Use build_sample Script

To make dotnet wrapper more user-friendly, We provide scripts to publish the project and generate executable binaries .

Windows

cd /path/to/orbbecsdk_dotnet

./build_samples.ps1

cd ./bin/Release/win-x64

./Samples.Color.exe

Linux

cd /path/to/orbbecsdk_dotnet

./build_samples.sh

cd ./bin/Release/linux-x64

./Samples.Color
