Low-Cost Dome for Multi-Purpose Digitalization on Small Object

The production of digital visual records via computer vision is becoming more
accessible. In this study, we build a low-cost multipurpose dome capable of supporting a
number of technological applications, including the necessity for consistent illumination
on Optical Character Recognition (OCR), Multispectral Imaging, and Photometric Stereo.
To achieve the best results possible for each process, a dome is constructed to contain
the environment. Nevertheless, each application procedure necessitates the production of
a unique dome. The dome is designed affordably by manipulating the position, brightness,
and color or Light-Emitting Diode (LED) sources. The size of a moveable dome
has become a significant alternative for digitizing small objects, which may then be duplicated
for educational purposes. The proposed dome is also linked to an application with
a Graphical User Interface (GUI) that allows the user to modify settings and control the
dome LED. The outcomes of our experiments indicate that our illumination dome can
be applied on three different applications. Despite its low cost, these results demonstrate
the dome’s versatility and potential applications in academic research settings and industrial
machine vision. In future, this dome can be used to produce a small object digital
acquisition.
