摘要： In order to set an inspection area, a measurement target is disposed onto a stage, a reference data of the measurement target is summoned, and a measurement data of the measurement target is acquired. Then, at least one feature object is selected in the measurement data and the reference data of the measurement target, and at least one feature variable for the selected feature object is extracted from each of the reference data and the measurement data. Thereafter, a change amount of the measurement target is produced by using the feature variable and a quantified conversion formula, and the produced change amount is compensated for to set an inspection area. Thus, the distortion of the measurement target is compensated for to correctly set an inspection area.

摘要： An inspection method includes photographing a measurement target to acquire image data for each pixel of the measurement target, acquiring height data for each pixel of the measurement target, acquiring visibility data for each pixel of the measurement target, multiplying the acquired image data by at least one of the height data and the visibility data for each pixel to produce a result value, and setting a terminal area by using the produced result value. Thus, the terminal area may be accurately determined.

摘要： In order to inspect a board, firstly, a measurement area is set on a board, and reference data and measurement data of the measurement area are acquired. Then, a plurality of feature blocks is established by a block unit so as to include a predetermined shape in the measurement area, and a merged block is established by merging feature blocks overlapped in the feature blocks. Thereafter, a distortion degree is acquired by comparing reference data and measurement data corresponding to a feature block except for the merged block and/or the merged block, and the distortion degree is compensated for, to set an inspection area in the target measurement area. Thus, an inspection area, in which distortion is compensated for, may be correctly set.

摘要： In order to set an inspection area in an inspection apparatus for inspecting a board, a plurality of measurement areas are set on a board, and then reference data and measurement data of at least one adjacent measurement area that is adjacent to a target measurement area for inspecting a measurement target, among the measurement areas, are acquired. Thereafter, at least one feature object is extracted from the adjacent measurement area. Then, a distortion degree is acquired by comparing reference data and measurement data corresponding to the feature object with each other, and thereafter the distortion degree is compensated for, to set an inspection area in the target measurement area. Thus, a conversion relation between the reference data and the measurement data may be correctly acquired, and an inspection area, in which distortion is compensated for, may be correctly set.

摘要： In order to measure a three-dimensional shape, feature information is read from a database. A board is transferred to a measurement position. A measurement head is transferred to an inspection area of the board. Light of a first lighting device for three-dimensional measurement and light of a second lighting device for two-dimensional measurement is illuminated onto the inspection area to photograph a first reflection image and a second reflection image that are reflected from the inspection area. The inspection area is realigned by comparing the feature information with at least one of the photographed first and second reflection images to inspect distortion of the inspection area. The realigned inspection area is inspected. Thus, the three-dimensional shape may be precisely measured.
