Method for monitoring health state of fully-open impeller in aviation centrifugal pump

The invention discloses a method for monitoring the health state of a fully-open impeller in an aviation centrifugal pump, and belongs to the technical field of centrifugal pump state monitoring. The method comprises the following steps that 1, an all-solid-state laser radar array is embedded in the inner wall of a pump shell; 2, a thermal infrared camera array is embedded in the inner wall of the pump shell; 3, calculating and generating a position information graph of each blade; 4, calculating and generating a vibration information graph of each blade; 5, calculating and generating a temperature information graph of each blade; 6, adaptively diagnosing the vibration health state of the blade; and 7, adaptively diagnosing the temperature health state of the blade. The non-contact type centrifugal pump impeller health state monitoring method based on vision is achieved, and the defects of a contact type measuring method in the technical field are overcome; the non-contact type centrifugal pump impeller healt
