Topology information is derived by correcting the phase information using a phase offset associated with a combination of two subsequent versions of the fringe pattern in the images or by estimating a surface normal for each pixel using a partial derivative of the phase information of the pixel in a first spatial direction and a partial derivative of the phase information of the pixel in a second spatial direction."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Deriving topology information of a scene","description":"An example apparatus has a processor to analyze images of projected shifted versions of a fringe pattern onto a scene to obtain phase information associated with the pixels in the image.
