奶牛体型评定三维图像同步采集系统（3D Synchronization Imaging System for Linear Appraisal of Dairy Cow Conformation）
奶牛 体型评定 三维图像
2009/5/22
设计奶牛体型评定三维图像同步采集系统，采用集散控制结构协调奶牛定位设备、图像采集装置按预定时序工作，应用3个CCD彩色摄像机与具有多通道、多独立图像芯片的DH—QP300型图像采集卡，实现了奶牛三维图像同步采集；采用LabVIEW软件作为采集主程序，通过调用动态链接库控制通用图像采集卡，选用场方式采集模式提高图像质量。试验证明，每头奶牛的图像采集与线性评定时间在3min左右,小于5min(标准)。...
