Method and system for detecting engine blade deformation

The invention discloses a method and system for detecting engine blade deformation, and belongs to the field of engine detection. In order to solve the problems that engine blade detection is low in efficiency and poor in precision, the invention provides a method for detecting engine blade deformation, and the method comprises the following steps: obtaining an original image which comprises a ball cap part in an engine and a to-be-detected blade part; respectively extracting the contour of the ball cap in the original image and the contour of the blade to be detected; according to the extracted ball cap contour conversion, calculating an ideal blade contour of the to-be-detected blade; and comparing the ideal blade contour with the extracted to-be-detected blade contour, and judging whether deformation occurs or not. Whether the blade deforms or not is judged by comparing the ideal blade contour with the to-be-detected blade contour, the precision is effectively guaranteed, the automation degree is high, and
