研发了一高分辨率三维立体摄影测量系统,并成功地应用于扑捉活猪的三维形状以用于饲养猪的研究.为调查饲料和猪生长的关系,将32头猪分成高Lysine和低Lysine两饲料组观察.连续14 周,每周用该系统拍摄猪的图像一次.该系统有三个立体摄影头,分别拍摄猪的侧面、背面和后腿面的立体图像.为重建猪的三维形状用以科学分析,我们研发了图像处理软件,包括相机标定、立体图像匹配和三维形状合成, 并提出一种从每周测得的形状中提取每只猪每周后腿肉的体积的算法.实验证明该系统是精确和可靠的.

A high-resolution 3D stereo photogrammetry system has been developed and it succeeded in capturing 3-D shapes of live pigs for pig husbandry research. For investigation of relationship between diet and growth of the pigs, 32 pigs were divided into high-lysine and low-lysine diet groups. Each pig was imaged once per week for 14 weeks. The system consists of three stereo pairs, which capture stereo images from side, top and rear views. Image processing software has been developed which included camera calibration, stereo image matching and range image integration to reconstruct 3D shapes of the pigs for animal science analysis. A conformation algorithm was proposed to deform a generic leg model to the shapes of pigs to extract quantitative ham volume weekly measurements from the shapes. The system has been proven to be accurate and reliable during the experiments.
