Related to clinical interests regarding the mapping of the eye pupil and its characteristics, dynamic pupillometry consists of the measurement of the eye's responses to luminous stimuli and has been the object of recent scientific discoveries, including the development of automatic systems capable of providing real time results. This research presents the development of an algorithm destined to process images and capable of instantaneously executing the dynamic measurement of the eye pupil, through the use of open source programming, free access development platforms and libraries. The project also includes the creation of a embedded system prototype designed to automatically determine the pupil attributes using video captures of the human eye, exploring the possibility of real time usage. The combination of all the stages of the system in a single device presents advantages like portability and versatility, along to the low cost of development obtained by the use of open source, low priced tools. The adopted hardware allows the configuration of a luminous stimulus to be applied in the eye to easily acquire an accurate pupil response, contributing to the future of the diagnostic analysis of the human eye and consequentially identifying undesired health indicators.
