POSITIONAL INFORMATION ACQUIRING METHOD OF MOUNTING MEMBERS, POSITIONAL INFORMATION ACQUIRING DEVICE OF THE SAME AND MANUFACTURING METHOD OF ELECTRONIC DEVICE

摘要

PROBLEM TO BE SOLVED: To acquire positional information such as positions, inclinations and components mounting positions of respective mounting members formed on a member divided into the multiple mounting members at a high speed.SOLUTION: A positional information acquiring method of mounting members comprises the steps of: imaging each of product substrates 11 frame-by-frame while relatively moving a CCD camera 4 with respect to a board divided into multiple product substrates 10 made of a ceramic material; setting a recognition image of each of the product substrates 11 such that the entire product substrate 11 set as an imaging object fits into a substantially center inside an image frame and the product substrates 11 adjacent thereto are partially imaged inside the image frame; performing image processing of each of the recognition images and calculating feature points of the product substrate 11 set as the imaging object and the product substrates 11 adjacent thereto partially imaged; and superimposing two recognition images in which the product substrates 11 set as the imaging objects adjacent to each other such that the feature points in common therewith coincide with each other, synthesizing an image of the entire board divided into the multiple product substrates 10 and acquiring positional information of all the product substrates 11 from a synthetic image acquired.
