中文摘要:
      对高温玻璃包装制品和其周围景物的单色辐射特性和CCD 的光谱响应特性进行了分析,可知CCD 对高温玻璃包装制品及其周围景物的辐照响应谱曲线存在交点,该交点为临界波长,且当波长大于临界波长时,高温玻璃包装制品对CCD 的辐照响应大于其周围景物对CCD 的辐照响应。由此可利用大于临界波长部分的辐照响应产生的高温玻璃包装制品与景物图像的灰度差的原理,来甄别高温玻璃包装制品及其边界。同时提出了采用灰度差原理甄别高温玻璃包装制品的条件,其为高温玻璃包装制品图像的灰度值大于其周围所有景物图像的灰度值,且只有临界波长位于CCD 的感光区间内,才能满足高温玻璃包装制品的甄别条件,临界波长越小甄别效果越好。
英文摘要:
      The monochrome irradiation response characteristic of high temperature glass packaging product and its surrounding scenery was analyzed as well as the irradiation response characteristic of CCD. The result showed that intersection point, which is critical wavelength, exists in the monochrome irradiation response characteristic curves of CCD to the glass packaging product and the surrounding; when wavelength is longer than the critical wavelength, monochrome irradiation response of high temperature glass packaging product will be greater than that of the surrounding scenery. It was put forward that the principle of discriminating high temperature glass packaging product from its surrounding scenery is the pixel gray difference in the wavelength longer the critical wavelength; the condition of discriminating high temperature glass packaging product in CCD image is the pixel gray of the high temperature glass packaging product greater than that of all the sceneries; in order to discriminating high temperature glass packaging product in CCD image, critical wavelength must locates in the photosensitive area of the CCD; the shorter the critical wavelength is the better the discriminating effectiveness.
