We present a technique to implement three-dimensional (3-D) object recognition based on phase-shift digital holography. We use a nonlinear composite correlation filter to achieve distortion tolerance. We take advantage of the properties of holograms to make the composite filter by using one single hologram. Experiments are presented to illustrate the recognition of a 3-D object in the presence of out-of-plane rotation and longitudinal shift along the z axis.
我们提出了一种基于相移数字全息术实现三维（3-D）物体识别的技术。我们使用非线性复合相关滤波器来实现失真容忍。我们利用全息图的特性，通过使用单个全息图来制作复合滤波器。给出了实验结果，以说明在存在沿z轴的平面外旋转和纵向位移的情况下对三维物体的识别。
