Patent number: 9746319Abstract: Technologies are generally described for generating depth data based on a spatial light pattern. In some examples, a method of generating depth data includes obtaining an image of one or more objects on which a spatial light pattern is projected, wherein blurring of the spatial light pattern in the image monotonously increases or decreases in a depth direction, calculating a value of a spatial frequency component of the image in a local image area around a pixel of interest, and determining depth data corresponding to the calculated value of the spatial frequency component by utilizing a preset relationship between depths and values of the spatial frequency component.Type: GrantFiled: March 17, 2015Date of Patent: August 29, 2017Assignee: EMPIRE TECHNOLOGY DEVELOPMENT LLCInventors: Kazutake Uehira, Masahiro Suzuki
