A measurement system for cattle using a computer vision technique has been developed. It is important to evaluate the quality of Japanese black cattle periodically during the growth process. Not only the weight and size of cattle, but also the posture and shape, are checked as the primary evaluation criteria. In this study, the digital point cloud data of cattle are obtained by three-dimensional computer vision devices from different angles simultaneously. These devices are calibrated in advance to have a common coordinate system. The point cloud data obtained from different angles is reconstructed on a common coordinate system, and digital cattle are generated in the computer considering the orientation of the cattle. The important specifications for evaluating the cattle posture are estimated from the reconstructed cattle model on the computer. The obtained data will be an important parameter for estimate the weight of the cattle.

本文研制了一种基于计算机视觉技术的牛体测量系统。在生长过程中，对日本黑牛的品质进行定期评价是十分重要的。不仅要检查牛的体重和大小，而且要检查姿势和形状，这是主要的评价标准。在本研究中，利用三维计算机视觉设备同时从不同角度获取牛的数字点云数据。这些设备都是预先校准的，以便有一个共同的坐标系。从不同角度获得的点云数据在一个共同的坐标系上进行重构，并根据牛的方位在计算机中生成数字牛。从计算机上重建的牛模型中估计出评价牛姿态的重要指标。所获得的数据将是估计牛体重的重要参数。
