Hog house ground cleanliness evaluation method based on video images

Abstract

The invention discloses a hog house ground cleanliness evaluation method based on video images, and particularly relates to the video image processing technology. The method comprises the following steps: storing a clean hog-free hog house ground image as a background image; acquiring a video image of the ground in the hog house through a camera; segmenting the acquired image by using a maximum between-cluster variance method to obtain a binary image of the pig; subtracting the acquired image from the background image by using an image difference method to obtain a binary image of the pig andthe excrement and urine; subtracting the binary images obtained in the two times to obtain a binary image of the excrement and urine; calculating the ratio of the number of the white pixels to the total number of the pixels in the binary image of the excrement and urine, comparing the ratio with a threshold T0, if the ratio is smaller than the threshold T0, judging that the cleanliness of the hoghouse is good, and if the ratio is larger than or equal to the threshold T0, judging that the hog house needs to be swept. The pig house cleanliness evaluation method overcomes the defect that in traditional pig breeding, the pig house environment completely depends on subjective experience for judgment, and is scientific and effective.

Description

technical field [0001] The invention relates to a method for evaluating the cleanliness of pig house floors based on video images, in particular to a video image processing technology. Background technique [0002] Pork occupies an important position in my country's food culture. With the rapid development of the national economy, people's quality of life has been significantly improved, and the demand for pork is increasing day by day. Therefore, the scale of pig breeding is also expanding. Large-scale pig farming There are more and more fields. [0003] The pig house is not only the growth environment of the pigs but also the working environment of the breeders. Therefore, the quality of the pig house environment not only affects the production of pigs, but also affects the health of the breeders. Most of the poisonous, harmful, pungent and unpleasant gases in the pig house are caused by the untimely cleaning of the excrement and urine of the pigs in the pig house, especi...
