Title:
INFORMATION PROCESSING DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2019/155903
Kind Code:
A1
Abstract:
The present disclosure relates to an information processing device and method capable of reducing a drop in precision of image projection correction. Using an image projection model involving the use of the distortion coefficient of an fθ lens where the image height of incident light is expressed as the product of a focal distance f and an incident angle θ of the incident light, an attitude estimation is performed on a projection unit for projecting an image and an imaging unit for capturing an image of a projection surface on which the image is projected . The present disclosure can be applied, for example, to an information processing device, a projection device, an imaging device, a projection imaging device, a projection imaging control device, an image projection imaging system, or the like.
