Automatic calibration system for infrared receiving head

The invention relates to the technical field of infrared communication and signal processing, in particular to an infrared receiving head automatic calibration system which comprises a multi-dimensional signal receiving module, a nonlinear distortion compensation module, a multi-signal interference analysis module, an intelligent calibration algorithm module and a pre-adjusting module. Wherein the multi-dimensional signal receiving module is used for capturing infrared signals of multiple angles and distances; the nonlinear distortion compensation module is used for performing real-time correction through a nonlinear compensation algorithm; the multi-signal interference analysis module is used for separating useful signals and interference signals; the intelligent calibration algorithm module is used for dynamically adjusting parameters of a receiving head according to the received useful signals and environmental data; and the pre-adjusting module is used for pre-adjusting the calibration parameters of the r
