New Orbbec Cameras Based on Microsoft iToF Depth Technology

Aug 22, 2023 — by Giorgio Mendoza 287 views

Last week, Orbbec revealed three new cameras developed in collaboration with Microsoft based on its Time-of-Flight (iToF) depth sensing technology seen on the HoloLens 2. The cameras target different applications including logistics, robotics, manufacturing and many other computer-vision applications.

The new cameras are called the Femto Bolt, Femto Mega, and Femto Mega I. Some key features of these devices include: they are 1-megapixel depth cameras with a wide 120° field of view (FOV) and a broad range from 0.25m to 5.5m.

Additionally, they are combined with a high-performance 4K resolution RGB camera with a 90° FOV. Furthermore, each camera includes a 6DOF IMU module that provides orientation data.

Orbbec states that the Azure Kinect Developer Kit and the Femto Bolt share identical depth camera modes and performance. However, the Femto Bolt’s color camera has been enhanced with HDR support. For further details, refer to the comparison table below.

On the other hand, the Femto Mega I and the Femto Mega are built around the NVIDIA Jetson embedded platform. Some of the main differences between these two devices is that the Mega I offers IP65 dust/water protection and it has an industrial grade M12-X coding ethernet port with PoE support.

The product announcement mentions that “Orbbec devices built with Microsoft’s iToF technology use the same depth camera module as Azure Kinect Developer Kit and offer identical operating modes and performance. Developers can effortlessly migrate their existing applications to Orbbec’s cameras by using the API bridge provided as part of their SDK.”

In terms of software development, the company will soon release an upgraded Orbbec 3D Club as the go-to place for 3D vision AI developers. Additionally, these new cameras will be supported by Orbbec SDK for easier integration.
