| 摘 要： | 利用摄像机前放置多枚平面镜组成的对称斗型腔体构成以物为中心的单目多视角摄像装置,在摄像机投影平面上直接获取从不同视角拍摄的珍珠表面图像;然后对不同视角的珍珠表面图像进行处理,获得反映珍珠品质的各种特征值;最后用特征融合的方式判定珍珠的品质。实验结果表明,设计的基于单目多视角机器视觉装置能保证在一个统一的颜色系统中一次获得珍珠整个球体表面的图像,实时完成珍珠的大小、形状、光泽、瑕疵和颜色等外观品质指标的视觉检测与分类。

| Abstract: | An imaging apparatus of monocular multi-view was designed by putting a symmetric bucket cavity, which was made by 4 planar mirrors, in front of the camera. An image of the pear surface from different perspectives could be obtained by this device; then, a variety of views which present pearl quality could be obtained by image processing. Finally the quality of the pearl could be determined by feature fusion. Experimental results show that the image captured of pearl entire surface could be obtained in a unified color system by the proposed device. Besides, the device accomplishes pearl online detecting and grading according to the quality indicator such as size, shape, luster, blemish and color. |
