Embodiment

[0118] 1. Take cross-sectional images of bovine eye muscle

[0119] First, adopt the beef marbling grading device of the present invention to ingest the bovine eye muscle cross-section image, and the bovine eye muscle cross-section image data enters the main control computer 8 through the image acquisition card 7 and provides it to the computer intelligent image analysis software system for intelligent analysis.

[0120] 2. Segmentation of the eye muscle region in the transverse section of the bovine eye muscle

[0121] 1. Select new parameters in the HSV color space for the ingested bovine eye muscle cross-section image, and use the threshold method to roughly segment the eye muscle area, which is conducive to the generation of images with obvious gradients

[0122] refer to Figure 5 -a, in the beef marbling image there will be "connecting bridges" between the eye muscles and the epiphytic muscles, appendages around the eye muscles, and uneven cross-sections, which are very...

Abstract

The invention discloses a beef marbling grade scoring method and a device, aiming at solving the problem that the manual scoring method has large subjectivity and arbitrariness. The method comprises the following steps: intaking a cross section image of cattle eye muscle; segmenting the eye muscle region on the cross section of the cattle eye muscle; extracting the marbling in the eye region and scoring on the grade of the marbling in the eye muscle, wherein, the grade scoring of the marbling in the eye region comprises that an index system of the grade scoring of the beef marbling and the grade scoring of the marbling in the eye region are established and four parameters of area density Sd and number N, distribution coefficient CVr and size uniformity CVs of the marbling are selected as scoring indexes. The invention also provides a beef marbling grade scoring device comprising a light source, an image acquisition card, a main control computer, a data acquisition card, a camera and a photoelectric sensor; and the beef marbling grade scoring method and the device are used for productive enterprises and inspection departments.

Description

technical field [0001] The invention relates to a method and device for scoring beef marbling grades based on computer vision technology, which are used in the field of automatic detection of beef quality grades by beef production enterprises and product inspection departments. Background technique [0002] Beef marbling score is an important basis for beef grade evaluation. At present, most of the production uses manual scoring by evaluators. When grading, the evaluators shall grade the beef marbling grade according to the standard sample of beef marbling and the evaluator's own experience. The manual scoring method has great subjectivity and randomness, which challenges the accuracy and authority of the scoring results. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the relatively subjective and arbitrary defects of the manual scoring method, and provide a beef marbling grade scoring method and device in th...
