Abstract

The invention discloses a method for evaluating the cleanliness of pig house floors based on video images, and in particular relates to video image processing technology. The method includes: saving the ground image of a clean pig house without pigs as a background image; collecting video images of the ground in the pig house through a camera; using the maximum inter-class variance method to segment the collected images to obtain a binary image of pigs ; Use the image difference method to make a difference between the collected image and the background image to obtain a binary image of pig and feces; make a difference between the two obtained binary images to obtain a binary image of feces; The ratio of the number of white pixels in the binary image to the total number of pixels, and the ratio and the threshold T 0 compare, if less than the threshold T 0 The cleanliness of the pig house is evaluated as good, if it is greater than or equal to the threshold T 0 Then it is evaluated that the pig house needs to be cleaned. The invention solves the deficiency that the environment of the pig house completely depends on subjective experience in traditional pig breeding, and provides a scientific and effective method for evaluating the cleanliness of the pig house.

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...
