Problems solved by technology

In the process of actually collecting images, because pigs have the habit of bowing their heads and other movements to look for food, it brings certain difficulties to image collection, resulting in low measurement efficiency and large measurement errors
Use the color image to extract the contour of the pig body. Affected by the environment and light, the dirt on the pig body and the high-gloss objects on the ground will cause contour extraction errors

Embodiment Construction

[0046] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0047] Kinect camera is a depth camera launched by Microsoft. Using the depth image to extract the object contour can effectively distinguish the foreground and background of the image, and avoid the contour extraction error problem caused by the close color of the background and foreground.

[0048] The present invention takes the pig body as an example, and designs a method for accurately measuring the length and width data of the pig body without contact and stress. Use kinect to collect depth video data, and process the video data in real time to judge whether a certain frame of image is suitable for body length and width detection, filter out the image frames for bod...

Abstract

Embodiments of the invention provide a Kinect video-based detection method for pig body length and body width. The detection method utilizes kinect to collect depth video data, and the video data areprocessed in real time; it is judged whether a certain frame image is suitable for body length and body width detection; image frames of the body length and body width detection are screened out froma video stream; and the pig body length and body width in the images are calculated. Therefore, contactless and stress-free detection is achieved, and accurate measurement of pig body length and bodywidth data is achieved.

Description

technical field [0001] The invention relates to the technical field of image processing, more specifically, to a method for detecting pig body length and body width based on Kinect video. Background technique [0002] In the process of raising pigs, the body length and width of pigs are an important parameter to judge the growth status of pigs. Pig body length and body width is also an important indicator in breeding pigs, meat quality evaluation and feeding management. For pig growth and development traits, body size traits, weight traits, appearance scores, and reproductive traits, breeders estimate individual breeding values ​​based on these phenotypic traits, and use them for selection and matching. Among them, the evaluation indicators such as body size and weight are mostly obtained through contact measurement methods. For example, the traditional measurement method of body size is manual measurement with a tape measure. Human error may also cause pigs to be stimulat...
