Deviations of the vertebral column have become increasingly common. The follow-up of a spine deviation is performed every 2 or 3 months by routine visits and X-ray examinations. X-ray examination produces ionising radiation, which, over time, can cause cancer and is accumulative: this risk increases with the number of exposures. This work describes the conception and initial development of a simple and portable system based on stereoscopy capable of performing a topographic analysis of the patient's back, as well as 3D reconstruction, in order to subsequently allow postural assessment. The stereoscopic system was built and calibrated, then the images underwent a process of rectification and point matching to create a depth map, so that preliminary results point to adequate 3D reconstruction of the back of a plastic phantom. The advantage of this method is the minimization of parallax errors, low cost, easy implementation and portability.
Este ensaio intenciona refletir as potencialidades do Repositório Institucional da Universidade do Estado da Bahia – o SaberAberto, suas perspectivas e desafios. Analisa os impactos e contribuições que este serviço pode e deve agregar à Universidade e, por consequência, à Educação Superior na Bahia. Demonstra como o uso e reuso do repositório poderá desencadear um processo de empoderamento dos indivíduos, de melhoria à gestão do conhecimento e de fortalecimento da pesquisa e produção científica/cultural da UNEB, destacando os benefícios aos pesquisadores, aos administradores acadêmicos e à Universidade.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
