20130194569 | SUBSTRATE INSPECTION METHOD - A substrate inspection apparatus for inspecting a substrate, on which a measurement object is formed, is shown. The substrate inspection method includes measuring a substrate, on which a measurement object is formed, generating a plane equation of the substrate, and acquiring a region of the measurement object formed on the substrate. After, by considering a height of measurement object a region of the measurement object is converted into a substrate plane by plane equation,. Then, the measurement object is inspected based on a region of the measurement object converted into a substrate plane by plane equation and a region of the measurement object by reference data. Therefore, an offset value of a measurement object is acquired according to a tilted pose of the substrate, and a distortion of measurement data is compensated by using the offset value, to improve a measurement credibility of a measurement object. | 08-01-2013 |
20130222579 | MEASUREMENT APPARATUS AND CORRECTION METHOD OF THE SAME - A measurement apparatus for measuring a substrate, on which a measurement object is formed, and a correction method of the same is shown. The correction method includes measuring a reference phase by measuring a phase of a substrate for measuring the reference phase by using an image-capture part, acquiring a tilted pose of a reference plane of the measured reference phase to an image plane of the image-capture part, and calculating a height that is required to correct the reference plane with regard to the image-capture part based on the tilted pose. Therefore, based on a tilted pose of a reference phase in order to correct a reference plane being a reference of measuring a height, a measurement credibility of the measurement object may be improved. | 08-29-2013 |
20140219542 | METHOD OF GENERATING HEIGHT INFORMATION IN CIRCUIT BOARD INSPECTION APPARATUS - A method of generating height information in a circuit board inspection apparatus, first, obtaining a first image corresponding to a first area and a second image corresponding to a second area with partially overlapped to the first area of a test board. Next, the first image and the second image are matched based on the overlapped area of the first and second area. Sequentially, a relative positional relationship of the first and second images is obtained from the result of matching. Sequentially, a combined grid image is generated by combining the first grid image and the second grid image based on the relative positioning relationship, wherein the first and second grid images are obtained by irradiating a grid patterned light toward a measurement object formed on the board inspection apparatus. Therefore, it is possible to generate an exact height information. | 08-07-2014 |
20150043065 | STEREO MICROSCOPE - A stereo microscope capable of not only adjusting the three dimensional effect of stereoscopic image but also focusing exactly even when the three dimensional effect of stereoscopic image is adjusted, is provided. A spacing distance of a pair of zoom unit can be adjusted so that a user can adjust three dimensional effect of image seen through an ocular lens according to personal tendency to improve convenience. Additionally, an object with a depth such as a hole can be exactly observed without interference of a boundary. Further, even though the three dimensional effect of an image is adjusted by adjusting the spacing distance of the pair of zoom units, the to focus of optical system can be exactly adjusted. | 02-12-2015 |
20150051725 | METHOD OF VERIFYING A SURGICAL OPERATION IMAGE MATCHING AND METHOD OF COMPENSATING A SURGICAL OPERATION IMAGE MATCHING - In order to verify a surgical operation image matching, a model of a target is manufactured. Then, a reference body is attached to the model. Then, three-dimensional reference data regarding to the model with the reference body attached thereto is obtained. Then, grid patterned light is emitted onto the model with the reference body attached thereto to obtain reflection image regarding to the model with the reference body thereto. Then, three-dimensional shape is measured by applying bucket algorithm to the reflection image regarding to the model with the reference body attached thereto, and measurement image is obtained from the three-dimensional shape. Then, the measurement image and previously obtained three-dimensional reference data are matched with reference to a surface of the model. Then, reference position of the target in the three-dimensional reference data is compared with estimated position of the target, which is estimated by the reference body in the measurement image. Therefore, the matching of the surgical operation can be verified. | 02-19-2015 |
20150109458 | METHOD OF REGISTRATING A CAMERA OF A SURGICAL NAVIGATION SYSTEM FOR AN AUGMENTED REALITY - A method of registering a camera of a surgical navigation system for an augmented reality which realizes an augmented reality with lowered error range is disclosed. The method of registering the camera of the surgical navigation system for the augmented reality enables single person to do the work by calculating and adjusting the coordinate of the optical center of the camera by moving the optical tracker, the camera, or the pattern board with a second marker attached on the pattern board, not manually attached on the pattern board. And, there is an effect of improving accuracy and safety of a surgery by realizing an augmented reality without generating an accumulated error by the second marker, since the spatial coordinate of the second marker attached on the pattern board maintains uniform. | 04-23-2015 |
