Two techniques for recognizing three-dimensional(3D) objects based on passive and active optical sensing followed by numerical correlation are presented. One technique uses passive sensing of 3D object based on integral imaging and the other technique uses active sensing based on digital holography. In both techniques, the 3D data is stored in two-dimensional(2D) form as digital format and then the detected 3D information is used for recognizing 3D object based on 2D correlation techniques or neural network. Experimental results in both techniques are presented.
