Disclosed is a method for inspecting a flat panel. The method for inspecting the flat panel includes the steps of: arranging a camera at a measurement location of the flat panel by horizontally moving at least one of the flat panel and the camera; automatically focusing the camera with respect to a measuring target of the flat panel at the measurement location; acquiring a plurality of images for the measuring target by vertically moving the focused camera within a set region on the basis of the present location of the camera when focusing the camera; selecting the image having the most definition for the measuring target among the acquired images; processing the selected image; and determining whether the measuring target is defective or not.

An image measuring apparatus for enhancing an accuracy of an image captured by an optical system and a method thereof are disclosed. The apparatus includes a CCD camera for capturing the object and outputting the captured image, a lamp for generating white light to illuminate a capturing area of the object, an illumination controller for controlling the lamp to be turned on, a piezoelectric actuator for controlling a minute height of the optical system with respect to the object, an image capturing device for acquiring the image captured by the CCD camera, a driving signal generator for outputting a driving signal to the illumination controller and the piezoelectric actuator when an enable signal is generated from the CCD camera, and an image signal processor for estimating height information of the object from data transmitted from the image capturing unit.

Apparatus for and method of measuring image

A method and apparatus for measuring the three-dimensional surface shape of an object using color informations of light reflected by the object. The method and apparatus for measuring the three-dimensional surface shape of the object, in which a real-time measurement of the three-dimensional surface is performed by projecting a beam of light having color information onto the object and detecting color distribution information according to levels of the object, thereby obtaining level information of the object.

Method and apparatus for measuring the three-dimensional surface shape of an object using color informations of light reflected by the object

An apparatus and method for measuring a three-dimensional shape of an object using a projection moir&#xe9; 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 moir&#xe9; phase, and unwrapping the moir&#xe9; 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.
