Method for estimating average weight of swinery in same pigsty based on computer vision

Abstract

The invention discloses a method for estimating the average weight of swinery in the same pigsty based on computer vision, which comprises the following steps of: installing a camera, establishing an approximate camera imaging model and establishing a height priori value table for each skeleton joint point of a pig; carrying out pig detection and instance segmentation on a pig image shot by a camera to obtain the rectangular frame position and edge contour information of a pig in the image, carrying out skeleton joint point detection on each detected pig, and identifying the posture of the pig by utilizing the edge contour information of the pig; estimating size information of each part of the pig by using bone joint points and posture information of the pig; and establishing a correlation model of the weight of the pig and the size information of each part of the pig by adopting regression analysis so as to estimate the average weight of the pig. According to the invention, the situation that a single pig is weighed without stopping and consuming manpower everyday is effectively avoided, non-contact type weight estimation is carried out on the swinery in the same pigsty, and the method has important practical application significance.

Description

technical field [0001] The invention relates to the field of computer vision and artificial intelligence technology, in particular to a computer vision-based method for estimating the average body weight of pigs in the same pen. Background technique [0002] With the growing economy of our country, our demand for live pigs is increasing. In order to better manage pig farms, it is necessary to raise pigs more scientifically through artificial intelligence and other technologies, so the intelligence of pig farms urgently needs to be improved. In real life, when pig farms raise pigs in pens, they usually divide pigs of the same size and weight into groups and house them in the same pen or pen. This is because, among pigs, in order to compete for food, powerful pigs often occupy the best resources in the pigsty, and there will be violent conflicts due to competition for food or drinking water. Under special circumstances, big pigs are also prone to unscrupulous attacks on smal...

Problems solved by technology

However, if the pigs are driven manually every day and weighed by the weighbridge, it will take a lot of manpower and time, resulting in serious waste, and at the same time, accidents are prone to occur when driving the pigs
