Release v2.16.0

Features

• OpenVINO 2022.1 support

Release v2.15.5

Bug fixes

• Updated FW with EEPROM fixes
• Fixed nlohmann json < v3.9.0 compatibility
• Fixed intermediary toolchain generation

Release v2.15.4

Features

• OV7251 (OAK-D Lite mono camera) configurable FPS (#455)
• Eeprom version v7 (#461)
• Improve PoE throughput and latency for some usecases (#428)

Bug fixes

• Regression: setLoadMesh didn't overwrite useHomographyRectification behavior (70d4796)
• VideoEncoder:
  • fix keyframe (IDR) rate config (before it didn't change from the default of 30)
  • fix resource computations for JPEG (preset FPS per instance was hardcoded to 30, it didn't allow video MJPEG at 4K 30fps + still 12MP at about 1fps). The encoder limit for JPEG is about 450.. 460 MPix/s
• Fixed incorrect stereo calibration for 2 batches of OAK-D-LITEs. Board revisions affected: boardName = OAK-D-LITE; boardRev = R1M1E1 and R0M0E0. If incorrect depth measurements were observed it's highly recommended updating to this version.

Misc

• Stereo: Auto enable distortion correction for fisheye lenses (#470)
• Stereo: Enable RGB alignment in examples where inference is performed on RGB camera (#457)
