ROBOTIC VISION, OPTICAL CORRELATION SYSTEM

阅读:223发布:2021-01-22

专利汇可以提供ROBOTIC VISION, OPTICAL CORRELATION SYSTEM专利检索,专利查询,专利分析的服务。并且A robotic vision, optical correlation system optically analyzes an input image (10) to provide identification and aspect information. The input image (10) is incident upon a spatial light modulator (14). A multiple holographic lens (22) then performs a multiple number of Fourier transformations upon the image (10). An array of matched filters (24) has the array of Fourier transforms incident thereon. Each matched filter (24) comprises a Fourier transform hologram of different aspect view of the object and passes an optical correlation signal indicative of the degree of correlation. The signal is then transformed by an inverse Fourier transform lens (26). A detector (28) then detects the signal. A processing circuit (30) compares the relative magnitudes of the signals to determine aspect information about the input image (10). The present invention includes a normalizing means (electronic (30) or optical) for each matched filter. This normalizing means operates on the basis of separate angular response curves for each matched filter.,下面是ROBOTIC VISION, OPTICAL CORRELATION SYSTEM专利的具体信息内容。
