Linux installation instructions
Currently, the only supported distribution is Ubuntu 18.04. To request support for other distributions, see this page.
libk4abt<major>.<minor>-dev package contains the headers and CMake files to build against
libk4abt<major>.<minor> package contains the shared objects needed to run executables that depend on
libk4abt as well as the example viewer.
The basic tutorials require the
libk4abt<major>.<minor>-dev package. To install it, run
sudo apt install libk4abt0.9-dev
If the command succeeds, the SDK is ready for use.
When installing the SDK, remember the path you install to. For example, "C:\Program Files\Azure Kinect Body Tracking SDK 0.9.2". You will find the samples referenced in articles in this path.
- [Breaking Change] Update to depend on the latest Azure Kinect Sensor SDK 1.2.0.
- [API Change]
k4abt_tracker_createfunction will start to take a
- [API Change] Change
k4abt_frame_get_device_timestamp_usecto be more specific and consistent with the Sensor SDK 1.2.0.
- [Feature] Allow users to specify the sensor mounting orientation when creating the tracker to achieve more accurate body tracking results when mounting at different angles.
- [Feature] Provide new API
k4abt_tracker_set_temporal_smoothingto change the amount of temporal smoothing that the user wants to apply.
- [Feature] Add C++ wrapper k4abt.hpp.
- [Feature] Add version definition header k4abtversion.h.
- [Bug Fix] Fix bug that caused extremely high CPU usage.
- [Bug Fix] Fix logger crashing bug.
- [Bug Fix] Fix memory leak when destroying tracker
- [Bug Fix] Better error messages for missing dependencies
- [Bug Fix] Fail without crashing when creating a second tracker instance
- [Bug Fix] Logger environmental variables now work correctly
- Linux support
- [Breaking Change] Downgraded the SDK dependency to CUDA 10.0 (from CUDA 10.1). ONNX runtime officially only supports up to CUDA 10.0.
- [Breaking Change] Switched to ONNX runtime instead of Tensorflow runtime. Reduces the first frame launching time and memory usage. It also reduces the SDK binary size.
- [API Change] Renamed
- [API Change] Broke
k4abt_frame_get_body()into two separate functions:
k4abt_frame_get_body_id(). Now you can query the body ID without always copying the whole skeleton structure.
- [API Change] Added
k4abt_frame_get_timestamp_usec()function to simplify the steps for the users to query body frame timestamp.
- Further improved the body tracking algorithm accuracy and tracking reliability
- [Breaking Change] Added support for NVIDIA RTX GPUs by moving to CUDA 10.1 dependency
- [API Change] Provide the joint output in millimeters to be consistent with the Kinect for Windows v2 SDK
- Further improved the body tracking algorithm accuracy and reliability.
