Development of an automated poultry inspection system that is low-cost, operates with minimum human intervention, and is able to maintain its accuracy is important to the U.S. Food Safety and Inspection Service (FSIS) and the poultry industry. Such a system, placed strategically in the processing plants, would help improve the inspection speed, minimize problems of human error and variability, ...

Software inspection, due to its repeated success on industrial applications, has now become an industry standard practice. Recently, researchers began analyzing inspection data to obtain insights on how software processes can be improved. For example, project managers need to identify potentially error-prone software components so that limited project resource may be optimally allocated. This p...

Spatial quantization error and displacement error are inherent in automated visual inspection systems. This paper discusses the effect of spatial quantization errors and displacement errors on the precision dimensional measurements for an edge segment. Probabilistic analysis in terms of the resolution of the image is developed for two-dimensional (2-D) quantization errors. Expressions for the m...

In practice, manufacturing systems are never perfect and may have low quality outputs. Therefore, different decisions such as reprocessing, sale at lower prices or diminishing are made according to industry and market. This paper investigates the importance of supply chain coordination through developing two models in centralized decision-making for an imperfect quality manufacturing system wit...

Traditional techniques like sand patch method and circular meter provide the reference value for pavement texture inspection. However, these traditional methods can not effectively fulfill the requirement of the highway pavement texture inspection. The non-contact displacement sensor that is able to provide more accurate and reliable results is desirable. The displacement sensor discussed in th...

The FAA currently uses its Automated Flight Inspection System (AFIS) to check the accuracy of Instrument Landing Systems (ILS) and other navaids. It is desirable to measure the deviations of the ILS to within 0.015 degree accuracy. Therefore, a flight inspection system requires a high level of accuracy in determining position which is computed by a Flight Inspection Truth System (FITS). The AFI...

Glass defects are a major reason for poor quality and of embarrassment for manufacturers. It is a tedious process to manually inspect very large size glasses. The manual inspection process is slow, time-consuming and prone to human error. Automatic inspection systems using image processing can overcome many of these disadvantages and offer manufacturers an opportunity to significantly improve q...

This paper reviews the development of a root mean squared error (RMS) flaw sizing criterion. The effect of using an RMS error criterion for the sizing performance of the PISC II [1-3] inspection teams is investigated. A crucial part of establishing an RMS error sizing criterion is the decomposition of the components in the RMS error into the sum of the squares of the mean error, the standard er...

It is very important to guarantee the quality of the industrial products by means of visual inspection. In order to reduce the soldering defect with terminal deformation and terminal burr in the manufacturing process, this paper proposes a 3D visual inspection system based on a stereo vision with single camera. It is technically noted that the base line of this single camera stereo was precisel...
