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.
