Flow tube static pressure hole quality detection method and system based on machine vision

The invention provides a flow tube static pressure hole quality detection method and system based on machine vision, and belongs to the technical field of aero-engines, and the method specifically comprises the steps: obtaining a standard static pressure hole image; under the same test condition as the standard static pressure hole image, shooting the to-be-tested static pressure hole by using camera equipment to obtain a sharp edge quality image of the to-be-tested static pressure hole; the static pressure hole standard block moves up and down in the to-be-measured static pressure hole, and a perpendicularity sequence image of the to-be-measured static pressure hole is obtained through camera equipment in a light spot sampling mode; and based on the standard static pressure hole image, respectively carrying out machine vision image processing on the sharp edge quality image and the verticality sequence image, obtaining a difference value between the standard static pressure hole image and the sharp edge qual
