摘要

在养猪业中，知道每头猪的确切体重对养猪户来说至关重要。这些信息可以帮助确定需要喂给特定育肥猪的饲料的数量和类型。给猪称重一直是个问题，因为这非常耗时，而且把猪放在秤上非常麻烦。此外，它会给动物带来压力。本研究的目的是建立一个基于rgb的系统，可以估计猪的日重和个体动物的体重。这项研究是在一个商业养猪场进行的，为期100天，我们对32头猪进行了监测。我们开发了一个系统来识别猪的特征，特别是头、肩、腹部和臀部。测试了三种不同的模型，它们的主要差异与图像处理和训练数据有关。使用这些模型，我们在预测和人工记录的动物体重之间获得了高于97%的准确性。该系统允许饲主使用我们的网络界面管理和监控他们的猪，使他们能够在养殖过程中做出关键决策。

Pig Weight Estimation According to RGB Image Analysis

In pig farming, knowing the exact weight of each animal is critical for the owner. Such information can help determine the amount and type of feed that needs to be fed to a specific fattening pig. Weighing pigs has always been problematic, because it is highly time consuming, and herding the pigs on the scale is extremely cumbersome. Moreover, it causes stress to the animals. The aim of our study was to build an RGB-based system that could estimate the daily weight of pigs and individual animal weight. The study was set up in a 100-day rotation in a commercial pig farm where we monitored 32 pigs. We developed a system to identify the features of the pigs, more particularly the head, shoulder, belly, and rump part. Three different modelswere tested, and their main differences were linked to image processing and training data. Using these models, we received higher than 97% accuracy between the predicted and the manually recorded weight of the animals. This system allows owners to manage and monitor their pigs using our web interface, allowing them to make crucial decisions during the farming process.

期刊介绍： Chinese Agricultural Science is a comprehensive, academic journal co-sponsored by the Chinese Academy of Agricultural Sciences and the Chinese Society of Agriculture. Founded in 1960, the journal is published publicly in the form of a bimonthly magazine. The contents of the journal include crop genetic breeding, cultivation, plant protection, soil fertiliser, horticulture, food science and engineering, animal husbandry and veterinary medicine, etc. It aims to promote the sustainable development of high-yield, high-quality, high-efficiency and environmentally friendly agriculture and animal husbandry. The aim of the journal is to report on the scientific research results of agriculture and animal husbandry in China, to enhance the innovation capacity of agricultural science and technology, to promote academic exchanges at home and abroad, and to serve the development of modern agricultural science and technology and scientific and technological progress. In addition, Chinese Agricultural Science is included in several international retrieval systems, including American Chemical Abstracts CA, Scopus, GeoBase, Russian Journal of Abstracts, CABI (Centre for Agricultural and Biological Information International) of the United Kingdom, and AGRIS (Food and Agriculture Organization of the United Nations).
