【摘要】 在生猪养殖中，体质量是最重要的指标参数之一，及时、准确地获取生猪的体质量信息具有重要意义。随着机器视觉技术的快速发展，生猪的非接触式体质量估测得到广泛关注。目前，非接触式体质量估测已经取得了一些研究成果，但由于真实养殖环境的复杂性，在养殖场实现生猪体质量的实时估测仍面临各种挑战。综述了近20 a国内外机器视觉技术在生猪体质量估测方面的研究进展和应用状况，分析总结了当前存在的问题和未来的研究重点，旨在为我国现代畜牧业的智能化转型升级提供参考。更多还原

【Abstract】 In swine breeding,body mass is one of the most important index parameters,so it is of great significance to obtain timely and accurately body mass information of swines. With the rapid development of machine vision technology,the non-contact body mass estimation of live swines has been widely concerned. At present,non-contact body mass estimation has achieved some research results,but because of the complexity of the real breeding environment,the real-time estimation of swine body mass in the farm still faces various challenges. This paper reviews the research progress and application of machine vision technology in swine body mass estimation in the past 20 years at home and abroad,and analyzes the existing problems and future research priorities,aiming to provide references for the intelligent transformation and upgrading of modern animal husbandry in China.更多还原
