Abstract

Webcam has been used widely throughout these days especially in healthcare, video monitoring and security and more. In the industry sector, uses of the webcam are significant especially for the inspection system in measuring objects. It is important to ensure that the quality of product releases in good specification before reach the market. There are few features that must be have in the webcam in defecting the measurement error of the object. In this study, the comparison of SD and HD webcam will be made to determine which webcam is suitable to be used for measurement of object in a vision system. In order to identify the accuracy of the measurement error between SD and HD webcam, the focal length will be change from 8 cm to 10 cm with 0.5 mm increment. The coding will be tested first using the MATLAB software before running the simulation. These webcams then will capturing the object in getting the dimension of height and width. At the end of the experiment, the result of measurement error for both webcams will be compared so that the best webcam can be determined to be used in measurement error in a vision system.
