A Powerful Auto Inspection Method Using Algorithm for Panel of Motor Body on the Variable Light Condition

摘要

PURPOSE: An automatically examining method for a vehicle body panel strong under variable illumination condition with an algorithm is provided to examine whether required parts are attached to a vehicle body panel precisely in a short time on the basis of images of the parts photographed by 9 cameras, thereby improving the productivity and reducing the reject ratio. CONSTITUTION: An automatically examining method for a vehicle body panel strong under variable illumination condition with an algorithm includes the steps of radiating light from a halogen lamp(10), passing the light through a circular passing lens(20) for simplifying the focus control and the light condensing for the light to be incident precisely to a part(70), dividing an image area of the part by similar light strength distribution, comparing the divided areas with frame data incorporated in a computer vision(50) to examine the divided areas, and stopping the production line and outputting the comparison and examination result to a graphic board(60) if the divided areas are different from the frame data.
