Apparatus for optimizing inspection of exterior of target object and method thereof

An apparatus for optimizing an inspection of an exterior of a target object, comprising:

• a light source configured to irradiate light to the target object;
• at least one camera configured to capture one or more sets of images of the target object, each set of images being captured under one or more predetermined settings;
• a memory configured to store the one or more sets of images of the target object and feature data including one or more predetermined exterior features of the target object;
• and
• a processor configured to:
• obtain the one or more sets of images from the memory;
• determine a first configuration of an operation for processing the one or more sets of images to inspect the target object, wherein the first configuration includes at least one of a first set of images on which the operation is to be performed among the one or more sets of images, a first set of image processes to be performed in the operation among a plurality of image processes, first parameter values for the first set of image processes, and a first sequence that each image process of the first set of image processes is performed in the operation;
• perform the operation on the first set of images under the first configuration;
• generate inspection data on the exterior of the target object from the first set of images that has been processed under the first configuration;
• generate an inspection score that indicates a proportion in pixels of an overlapping area between a first area on the target object from the inspection data and a second area on the target object from the feature data with respect to the second area;
• compare the inspection score with a predetermined threshold score;
• set the first configuration as an optimal configuration of the operation if the inspection score satisfies the predetermined threshold score;
• determine a second configuration of the operation by modifying the first configuration if the inspection score does not satisfy the predetermined threshold score;
• and
• control the light source and the at least one camera to obtain additional sets of images of the target object in settings that are different from the one or more predetermined settings, when inspection scores do not satisfy the predetermined threshold score after repeating the modification of configurations of the operation a predetermined number of times.
