Digital zenith camera of the University of Latvia

2016

Design of digital zenith camera in Institute of Geodesy and Geoinformatics of the University of Latvia started in 2009. Now, after tests of a prototype, improvements of design and manufacturing of the second version, it has reached operational status. The paper describes construction of camera, features of it‘s control software. Vertical deflection determination results are discussed.

Adolescent idiopathic scoliosis screening: Could a school-based assessment protocol be useful for an early diagnosis?

2020

BACKGROUND: Adolescent idiopathic scoliosis screening still needs a considerable implementation, particularly throughout a school-based assessment protocol. OBJECTIVE: This study aims to evaluate the effectiveness of clinical examinations currently in use for the diagnosis of adolescent idiopathic scoliosis, through a survey carried out in secondary schools to standardize a screening protocol that could be generalized. METHODS: In their classrooms, the adolescents underwent an idiopathic scoliosis screening through three examinations: Adam’s test, axial trunk rotation (ATR) and plumb line. In case of single positivity to one of the three examinations, a column X-ray examination was recommen…

Digital zenith camera for vertical deflection determination

2012

Recent accomplishments in advancement of accurate astrometric reference star catalogues, development of digital imaging technology, high accuracy tiltmeter technology, and geocentric coordinate availability provided by GNSS, have made possible accurate, fast and automated determination of vertical deflections using astrometric methods. Zenith cameras for this kind of measurements have been developed or are being developed by several research groups. The paper describes a research project by Institute of Geodesy and Geoinformation, intended to design a portable digital zenith camera for vertical deflection determination with 0.1” expected accuracy. Camera components are described, proposed d…
