  3. Helios2 0.3 MP IP67 3D Camera

The Helios2 Time of Flight (ToF) camera is an IP67 “factory tough” 3D camera featuring Sony’s DepthSense sensor, engineered for high performance operation in industrial environments. Built for demanding 24/7 environments and a variety of industrial 3D applications such as robotics, 3D inspection, and logistics, including advanced material handling, pick and place, sorting, palletization / de-palletization, volume estimation, and more. The Helios2 delivers sub-millimeter precision and improved accuracy compared to the previous Helios. The calibration between the VCSELs and sensor timing is enhanced resulting in more 3D detail, along with improved edge detection to reduce flying pixels and overall noise.

*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)
