The Lucid Vision Labs Helios2 Time of Flight (ToF) 3D camera features a Sony DepthSenseTM IMX556PLR 1/2" global shutter CMOS back-illuminated ToF sensor.
Helios2 outputs 3D point clouds in real-time for use in a variety of industrial 3D sensing and depth measurement applications to sub-mm (< 1mm) precision, with optional 3.2MP color image texture-mapped overlay. Six operational working distance modes maximize 3D performance based on the required distance range and come with the ability to adjust the starting point of each model along the entire 0.3 to 8.3m working range of the camera.
All Lucid Vision Labs Helios2 3D ToF cameras, including the Helios2 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 250 µs exposure time, all other distances using 1000 µs exposure time measured with white paper target.
Test Conditions
Target: White paper mounted on bar attached to motion stage
Helios2 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)
