Gravel specification machine vision detection method and system, electronic equipment and storage medium

The invention discloses a sandstone specification machine vision detection method and system, electronic equipment and a storage medium, and belongs to the technical field of sandstone specification detection.The detection method comprises the following steps that an image of sandstone with the known specification and imaging parameters of the image are obtained for calibration; acquiring an image and an imaging parameter of the to-be-detected sandstone; preprocessing the image of the sandstone to be detected; obtaining an evaluation index value of the to-be-detected sandstone image according to a preprocessing result; and determining the sandstone specification of the to-be-detected sandstone according to the corresponding relationship between the evaluation index value and the sandstone specification. The gravel specification is detected through machine vision, the subjective influence of human eye observation can be avoided, and the detection result is objective and accurate; the machine vision is used for
