Sow prenatal behavior classification method and system based on thermal imaging

Abstract

The embodiment of the invention provides a sow prenatal behavior classification method and system based on thermal imaging. The sow prenatal behavior classification method comprises: obtaining an infrared image containing sows and fences from the upper portion of a pig house; acquiring a region-of-interest image containing the sow in the infrared image, and determining the position of a railing inthe region-of-interest image; carrying out edge detection on the interest area image, and extracting a railing straight line as a boundary to calculate the head area of the sow below the railing; converting the interest area image into a binary image, and classifying sow feeding behaviors and drinking behaviors based on the binary image. Image information is collected by using a thermal infraredimager, data is processed, feature data of an image is extracted, and behaviors of sows in the image are judged. The method has the characteristics of reducing labor force and detecting antenatal changes of sows in real time.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and system for classifying prenatal behavior of sows based on thermal imaging. Background technique [0002] Behavior is an important part of animal individual information. With the continuous development of the pig industry, automated pig raising has become the development trend of the pig industry, and the automatic monitoring and identification of animal behavior has become one of the current research hotspots. Animal behavior reflects their welfare status, and they contain important information that allows producers to better manage their livestock. Real-time monitoring of sow behavior signs, timely understanding and analysis of sow behavior is an important basis for judging the delivery time and health of sows, and is of great significance for improving pig welfare, meat production and quality. In the traditional pig raising industry, the intuition and exp...
