提出一种基于结构光的光电混合系统。为提高相关识别率,把结构光和基于SDF的相移功率谱相减的联合变换相关器结合起来,完成相关识别。该系统兼有物体的灰度信息和形廓信息,是一种具有广阔应用前景的图像识别系统。
An optical hybrid system based on structured light is proposed. In order to improve the recognition rate, a joint transform correlator for subtracting the structured light from the SDF-based phase shift power spectrum is combined to complete the correlation identification. The system combines the gray information and the contour information of objects, which is a kind of image recognition system with broad application prospects.
