Patent number: 8525879Abstract: A depth detection method includes the following steps. First, first and second video data are shot. Next, the first and second video data are compared to obtain initial similarity data including r×c×d initial similarity elements, wherein r, c and d are natural numbers greater than 1. Then, an accumulation operation is performed, with each similarity element serving as a center, according to a reference mask to obtain an iteration parameter. Next, n times of iteration update operations are performed on the initial similarity data according to the iteration parameter to generate updated similarity data. Then, it is judged whether the updated similarity data satisfy a character verification condition. If yes, the updated similarity data is converted into depth distribution data.Type: GrantFiled: July 23, 2010Date of Patent: September 3, 2013Assignee: Industrial Technology Research InstituteInventors: Chih-Pin Liao, Yao-Yang Tsai, Jay Huang, Ko-Shyang Wang
