General Description

BELICE is a proprietary infrared dot-pattern illuminator for stereoscropic imaging platforms. It produces a very high-contrast dot pattern that stereo-matching algorithms can use to address low-texture situations and achieve high-accuracy depth maps. An additional benefit of the dot pattern is a reduction of the computational load required to perform the depth calculation.
The BELICE dot-pattern illuminator is provided in a miniature package that is compatible with standard lead-free reflow processes. As such, it can be successfully used onboard of a great variety of 3D sensing platforms, from mobile to IoT to robotics.
A pair of BELICE-SD emitters produce approximately 10k dots at 850nm. A 940nm version is currently under development.

This product suits for the following applications:

  • Active stereo 3D cameras
  • Depth sensing cameras
  • Mobile
