Patent number: 9664888Abstract: A method of detecting multi-surfaces of an object includes providing an imaging system capable of detecting surfaces of the object. After system parameters are set up, two-dimensional images of the object at multiple Z steps can be acquired. Each surface of the object can then be extracted using two steps. In a first step, the surface can be constructed based on a confidence threshold. In a second step, the surface can be enhanced using an interpolation filter.Type: GrantFiled: April 21, 2015Date of Patent: May 30, 2017Assignee: Zeta Instruments, Inc.Inventors: Ken Kinsun Lee, Ronny Soetaman, Zhen Hou, James Jianguo Xu, Rusmin Kudinar, Vamsi Mohan Velidandla, Ben Garland
