WIPO Patent Application WO/2017/203777
Kind Code:
A1
Abstract:
Provided is an electronic device that captures an image, and that accurately recognizes characters in the image. The electronic device is provided with an imaging unit, a distance measurement unit, a shape estimation unit, and a coordinate conversion unit. The imaging unit images an object and captures image data. The distance measurement unit measures each distance from the imaging unit to a plurality of measurement points on the surface of the object. The shape estimation unit estimates the shape of the object from the measured distances. The coordinate conversion unit performs, on the image data, coordinate conversion for converting three-dimensional coordinates on the surface of the object to plane coordinates on a prescribed reference plane on the basis of the estimated shape.
