The Lucid Vision Labs Helios2 Wide 3D Time of Flight (ToF) camera includes the same features as the Helios2 ToF camera and Helios2+ ToF camera – a Sony DepthSense™ IMX556 CMOS sensor, a GigE interface, GigE Vision and GenICam 3D standards compliance, M12 connectors for easy installation with a rugged IP67 Factory Tough™ design.
What sets the Helio2 Wide ToF camera apart from the Helios2 and Helios2+ ToF cameras is the wide-angle lens that enables 4 times the viewing area of an object to be captured – that’s a 108° x 78° field of view (FoV) compared to the Helios2 and Helios2+ 69° x 51° field of view (FoV).
Since the Helios2 Wide ToF camera can capture objects at a closer distance, there are more flexible options for fitting the camera into industrial machine vision systems. The Helios2 Wide wide-angle ToF camera is suitable for many industrial machine vision applications such as robotics, 3D inspection, and logistical applications that require a wide FoV.
All Lucid Vision Labs Helios2 3D ToF cameras, including the Helios2 Wide ToF camera, have an IP67 rating making them suitable for a wide range of indoor and outdoor applications. A GigE interface and plug-and-play functionality enables users to quickly integrate the camera into their systems and start capturing 3D data. Helios2 3D ToF cameras also include the Arena SDK and 3D point cloud viewer software.

*0.5 m distance precision measured with 750 µs exposure time, all other distances using 3000 µs exposure time measured with white paper target.
Test Conditions
Target: White paper mounted on bar attached to motion stage
Helios2 Wide positioning: mounted on tripod, laser distance meter used to measure distance from case front to stage zero position
Camera setting: Coord3D_C16 Pixel Format, bilateral filtering OFF, camera warmed up for 20 minutes.
Imaging environment: Room light on during testing, black material used to minimize reflections off floor
Motion stage moved in 50mm steps, for each step measure depth over 10×10 pixel ROI at image center, repeat 32 times at each position
Accuracy measured as difference between camera’s average measured depth across the ROI and 32 images and the ground truth depth (stage zero distance + stage position)
