| 发明名称 | Recording method for obtaining an image of an object and recording device | ||
| 摘要 | A method for recording an image of an object includes projecting a strip pattern onto the object, recording the projected strip pattern as raw image data using a camera, and calculating an image of the object from the raw image data. A strip pattern having a duty cycle of less than 1 can be used to increase measuring precision during measurement of a translucent object, and can eliminate a need for additional contrast agents for a recording of the object. | ||

| 主权项 | 1. A method for creating an image of an object, comprising the steps of: a) projecting light through an optical grid having a Gaussian intensity distribution and toward an object to create a striped pattern on the object, said striped pattern having an area-specific mark-space ratio less than 1 and an intensity distribution corresponding to a Gaussian distribution; b) recording the striped pattern projected onto the object with a camera to form a raw image; and c) computing an image of said object from said raw image. | ||
