[目的] 针对目前平养肉鸡跛行检测主要依靠饲养员的人为观察,存在主观因素强、效率低等问题,提出一种基于三轴加速度传感器的肉鸡步态检测方法。[方法] 研制了一种基于三轴加速度传感器的无线运动脚环,通过肉鸡行走自检测(WSD)算法确定肉鸡行走的有效数据点,利用逻辑回归算法建立肉鸡健康与跛行二分类模型,最后通过欧氏距离度量肉鸡跛行程度。[结果] 无线运动脚环能快速采集和传输肉鸡腿部运动信息,肉鸡健康与跛行二分类模型的平均准确率为93.88%,通过欧氏距离可以近似表征肉鸡跛行的严重程度。[结论] 提出了一套肉鸡步态自动检测算法,为平养条件下肉鸡步态检测提供一种新方法。
[Objectives] The current modes of broiler lameness detection system mainly rely on breeders,and hence are always faced with the problem of subjectivity and unreliability. This study proposes a gait detection system based on three-axis acceleration sensor.[Methods] A wireless foot-loop based on three-axis acceleration sensor was developed. The effective data points for broiler walk was determined by a walking self-detection(WSD) algorithm. Logistic Regression algorithm was used to establish a two-class model for health-lameness in broilers,and finally,the degree of lameness was measured by Euclidean distance.[Results] The test results showed that the wireless foot-loop could quickly collect and transmit the broiler leg movement information. The average accuracy rate of broiler health-lameness two-class model was 93.88%. The Euclidean distance approximated the extent of lameness.[Conclusions] An automatic detection algorithm for broiler gait was proposed to provide a new method for broiler gait detection underfloor system.
