Abstract:
An apparatus and method for measuring a three-dimensional shape of an object using a projection moiré device. The method comprises the steps of obtaining a grid pattern image projected on a reference plane of a moving table and applying a buckets algorithm thereto, thereby achieving a reference phase, obtaining a grid pattern image projected on the object set on the moving table and applying a buckets algorithm thereto, thereby achieving an object phase, calculating a difference phase between the object phase and the reference phase, thereby achieving a moiré phase, and unwrapping the moiré phase, thereby achieving a level information of the object. The apparatus and method measure the three-dimensional shape using a projection grid without a reference grid, thereby achieving compactness of equipment, simplicity in usage and manufacturing cost reduction.
Abstract:
A method and apparatus for minimizing the number of key pressings required for character input. When a key is initially pressed, a controller searches, in a storage unit, for characters corresponding to the keys pressed, and sequentially displays the characters in a current cursor position according to a predetermined time that the key is pressed. When pressing of the key is terminated, the character presently displayed in the current cursor position is maintained and the cursor moves to the next cursor position. Since the wanted character can be inputted by pressing only one key, there is a minimal amount of keys utilized to input a character. In particular, by utilizing a consecutive input, the same character can be inputted more effectively and conveniently.
