  In 2015, the LHCb experiment established a new and unique software trigger
strategy with the purpose of increasing the purity of the signal events by
applying the same algorithms online and offline. To achieve this, real-time
calibration and alignment of all LHCb sub-systems is needed to provide
vertexing, tracking, and particle identification of the best possible quality.
The calibration of the refractive index of the RICH radiators, the calibration
of the Hybrid Photon Detector image, and the alignment of the RICH mirror
system, are reported in this contribution. The stability of the RICH
performance and the particle identification performance are also discussed.
