METHOD AND APPARATUS FOR MEASURING 3-DIMENSIONAL OBJECT SHAPE BASED ON SHADOWS
Abstract:
An apparatus measures a 3-Dimensional (3D) shape of an object. The apparatus includes a light emitting unit and a light receiving unit that are arranged to face each other with the object disposed in a space defined therebetween, wherein the light transmitting unit being arranged to scan the object, and the light receiving unit being arranged to sense a shadow of the scanned object formed thereon. The apparatus includes a rotation unit arranged to rotate the light emitting unit and the light receiving unit about a same rotational axis by a preset rotation angle until the rotation is fully made by a desired target angle and a shape restoration unit configured to measure a 3D shape of the object using shadows that are obtained for each preset rotation angle.
