Problems solved by technology
However, current visual inspection techniques, such as those by human workers, always miss defective products, and also lack procedures to account for new product defects (e.g., those caused by aging production lines)
Therefore, there are challenges in initially identifying product defects, especially those that develop over time

Embodiment Construction
[0029] Reference will now be made to the embodiments, examples of which are illustrated in the accompanying drawings. In the following description, several specific details are set forth in order to provide an understanding of the various embodiments described. It will be apparent, however, to those skilled in the art that the various embodiments described may be practiced without these specific details. In other instances, well-known methods, procedures, components, circuits and networks have not been described in detail so as not to unnecessarily obscure aspects of the embodiments.
[0030] It will also be understood that, although the terms first, second etc. are used in some instances herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first image could be termed a second image, and, similarly, a second image could be termed a first image, without depar...

A method of improving quality inspection comprising: (i) receiving a first command to acquire a first image of a product surface, (ii) positioning a camera at a first image substantially adjacent the product surface by actuating a plurality of rotatable joints. at a location, and acquiring a first image of the surface of the product. The method also includes, after acquiring the first image: (i) processing the first image to identify a defect in the first image and a relative location of the defect in the first image, and, (ii) based on the first position of the camera and the relative position of the defect in the first image, determine a second position of the camera, and, (iii) reposition the camera from the first position to the second position by actuating the plurality of rotatable joints. The method also includes acquiring a second image.
Description
technical field [0001] The present application generally relates to production lines, including but not limited to visual inspection of products on the production line. Background technique [0002] Manufacturers implement various quality control measures to reduce the number of defective products entering the circulation of goods. Some quality control measures involve visual inspection of products. However, current visual inspection techniques, such as by human workers, always miss defective products, and also lack procedures to account for new product defects, such as those caused by aging production lines. Thus, challenges exist in initially identifying product defects, especially product defects that develop over time. Contents of the invention [0003] Accordingly, a need exists for a method and system for identifying defective products before they enter the circulation of commerce. One solution to this problem is to use a robot (e.g., a robotic arm 402 with a came...
