METHOD AND APPARATUS FOR QUALITY ASSURANCE OF AUTOMOBILE COMPONENT USING MARKER

摘要

The present invention discloses a method and apparatus for quality assurance of an automobile component using a marker. The method comprises (a) a step in which an image photographing unit photographs a fully assembled component to which a marker having a predetermined shape is already attached by being driven according to an operation of a terminal having a photographing function; (b) a step in which an image pre-processing unit corrects the basic image using the marker and outputs, after receiving the photographed image, using an image processing function, and specifies the dimensions of the fully assembled components according to the difference in size and shape of the components fully assembled with the markers; (c) a step in which a distance and step measurement unit measures a distance and a step of the component by receiving the corrected basic image and performs a measuring part measurement algorithm; (d) a step in which a measurement data storage unit receives and stores measurement data on the measured distances and steps; and (e) a step in which an image output device receives and displays the corrected bas image and the measurement data, wherein the measuring part measurement algorithm calculates an absolute length of the vertical line with respect to an absolute length of the marker by using an intersection between a vertical line based on a measurement reference point of the measuring part of the component in the corrected basic image and a relative reference point of the component to measure the distance and step of the component.
