specific Embodiment approach

[0064] In the first step, after the product image is collected, first use the "retraction scanning method" to scan to determine whether there is an intestinal object in the picture; if "there is no intestine in the picture", stop the subsequent scanning detection; if there is intestine in the picture, Then determine the approximate area where the intestinal body exists in the digital image.

[0065] See the specific process figure 2 Flowchart of the "retraction scan" of the region of the intestinal body shown. After the scanning calculation process, the coordinates of the four corners of the general area where the intestinal body is located can be obtained (see image 3 by (x 1 ,y 1 ), (x 2 ,y 1 ), (x 2 ,y 2 ) and (x 2 ,y 1 ) and other quadrilateral areas determined by four corner points).

[0066] In the second step, if there is "intestine in the picture" and the approximate area where the intestinal body exists has been determined, then scan and detect the two wra...

Abstract

The invention relates to a method for quickly scanning and detecting the appearance and the quality of an emulsion-type sausage food product based on machine vision. The method includes inputting an acquired image of the emulsion-type sausage food product into a computer at first and processing the image; preliminarily determining a sausage location area in the image; determining coordinates of a left binding endpoint and a right binding endpoint of a sausage; and carrying out equal-interval and short-interval scanning for feature points of the upper lateral edge and the lower lateral edge of the sausage to obtain edge feature points of two sides of the sausage and coordinate values of the edge feature points, and acquiring the appearance and the quality of the sausage. The method can be used for quickly scanning large quantities of images of emulsion-type sausage food products, accordingly, data processing workload is greatly reduced, standardized and objectified quality detection for the products can be realized, detection efficiency also can be greatly improved, large quantities of labor resources and costs are saved, and application of intelligent image detection technology to appearance and quality detection for the sausage food products is certainly promoted.

Description

technical field [0001] The invention belongs to the technical field of computer intelligent detection of product images, and relates to a machine vision-based rapid scanning detection method for the appearance quality of emulsified intestinal food products. Background technique [0002] Computer image processing technology and its application in industrial quality inspection have developed rapidly. However, at present, most sausage product processing enterprises in my country still rely on "human vision and subjective judgment" to detect the appearance quality of products such as "casing swelling or bursting" and "degree of bending". This detection method not only takes up a lot of manpower, but is also easily affected by factors such as personal vision, emotion, fatigue, light, etc., resulting in low work efficiency and large differences in sorting. To a certain extent, it restricts the development of intestinal food product processing enterprises. In order to improve the...
