Orbbec Femto Bolt

An indirect time-of-flight RGB-D camera from Orbbec, positioned as a drop-in replacement for Microsoft’s discontinued Azure Kinect.

Femto Bolt is an RGB-D depth camera from Orbbec that uses Microsoft’s indirect time-of-flight (iToF) technology, which computes distance from the phase difference between emitted infrared light and its reflection. Orbbec states that Femto Bolt’s depth modes and performance match the Microsoft Azure Kinect DK, and it ships with a K4A-compatible wrapper SDK, so code written for Azure Kinect needs little to no change. Depth modes include a narrow field of view at 640×576 @ 30fps and a wide field of view up to 1024×1024 @ 15fps, with a range of about 0.25–5.46 meters; color goes up to 4K, and it has a built-in 6-axis IMU. It is powered and connected over USB-C and is intended for indoor use only. Labs commonly mount it as a fixed third-person camera for collecting point clouds.

ExampleA lab replaces its old Azure Kinect with a Femto Bolt; after installing the official K4A wrapper, the existing point-cloud capture scripts keep running unchanged.
