Multi-camera system for close-up supervision in test-fixtures using openCV and optics

Abstract: The test-fixture is a device used for testing of electronic circuits in production, that is produced by the Lund based company mikrodust AB. In the test-fixture, cameras are both used for supervision of products-in-testing and in the products themselves. This poses a challenge due to the compact size of the test-fixture and the number of mechanical elements. This thesis aims to investigate how clear and readable images can be captured in the test-fixture, while also not be to hard to implement from a mechanical stand-point. Solutions using both optical components and image processing algorithms are investigated. Moreover, also to explore the ideal lens combination and its optimal placement based on specific camera attributes, including field of view, minimum focus distance, and physical size. The results of this thesis show that this problem could be solved with the use of optical components while the use of image processing algorithms were slightly redundant. This work also provides information on what solution is most appropriate given a camera product's characteristics.
