    摘要:

    利用攝像機(jī)前放置多枚平面鏡組成的對稱斗型腔體構(gòu)成以物為中心的單目多視角攝像裝置,，在攝像機(jī)投影平面上直接獲取從不同視角拍攝的珍珠表面圖像,；然后對不同視角的珍珠表面圖像進(jìn)行處理,，獲得反映珍珠品質(zhì)的各種特征值,；最后用特征融合的方式判定珍珠的品質(zhì),。實(shí)驗(yàn)結(jié)果表明,，設(shè)計的基于單目多視角機(jī)器視覺裝置能保證在一個統(tǒng)一的顏色系統(tǒng)中一次獲得珍珠整個球體表面的圖像,，實(shí)時完成珍珠的大小,、形狀,、光澤,、瑕疵和顏色等外觀品質(zhì)指標(biāo)的視覺檢測與分類。

    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.
