Tobacco shred length measuring method and system, computer readable medium and measuring equipment

The invention provides a tobacco shred length measuring method and system, a computer readable medium and measuring equipment. The measuring method comprises the following steps: acquiring a tobacco shred true color image; preprocessing the tobacco shred true color image; performing connected region segmentation on the preprocessed tobacco shred images so as to segment the plurality of tobacco shred images into single tobacco shred images; refining the image of the single tobacco shred to extract a skeleton of the single tobacco shred; two end points with the longest distance are searched in the framework of the single tobacco shred, the part between the two end points with the longest distance is divided into a plurality of sections according to corresponding internal points, the pixel distance between the sections is calculated, and the pixel distance between the sections is added to obtain the pixel value of the length of the single tobacco shred; and fitting a tobacco shred length prediction model based o
