Brief comparison

Helios2 The 3D Time of Flight (ToF) camera provides real-time 3D depth imaging with high precision and sub millimeter level accuracy. This camera features Sony's IMX566PLR ToF sensor, combined with LUCID's Factory Tough IP67 design, making it ideal for all-weather operation in challenging industrial environments.

Helios2+It is an advanced version of the Helios2 ToF camera, offering two additional modes. High dynamic range mode and high-speed ToF mode. The high dynamic range mode combines multiple exposures to provide accurate depth information in scenes containing high and low reflection objects. High speed mode uses single phase measurement to achieve depth perception, achieving faster acquisition speed and higher frame rate for moving targets, but sacrificing absolute accuracy and measurement distance range. Both HDR and high-speed mode are fully implemented through processing on the camera.

due toHelios2 WideHaving a wider 108 ° x 78 ° field of view (compared to the 69 ° x 51 ° field of view of Helios 2/2+), its visible area has increased fourfold. This allows Helios2 Wide to image larger areas at the same distance as Helios2, or the same areas at closer distances to the target, making camera installation more flexible.

All Helios2 models have the same Factory Tough industrial design, with IP67 dust and water resistance, and are 100% compatible in both mechanical and software aspects.
