RealSense SDK version 2.27.0 now available

[MartyG]

Hi everyone,

Version 2.27.0 of the RealSense SDK is now available for download from the link below.

https://github.com/IntelRealSense/librealsense/releases/ 

API CHANGES

T265 Calibration Write APIs: Allow custom calibration to be provided to the device and committed to device flash memory. There is also a mechanism to roll-back to factory calibration. Currently these APIs are only implemented for the T265, but similar scheme is likely to be used for other families

- rs2_set_intrinsics - set video stream profile intrinsic calibration

- rs2_set_extrinsics - set extrinsic calibration between two stream profiles

- rs2_set_motion_device_intrinsics - set motion stream profile intrinsics

- rs2_reset_to_factory_calibration - Resets the device to factory calibration when available

- rs2_write_calibration - Commit calibration changes to device flash memory

- rs2_clone_video_stream_profile - Utility function used when developing custom processing blocks that modify video stream resolution
