Advances in Science, Technology and Engineering Systems Journal, Volume 6, Issue 2, Page # 965–970, 2021; DOI: 10.25046/aj0602110

Abstract:

Early detection and proper management of adult degenerative scoliosis (ADS) are important for health promotion. This study aims to develop an ADS screening tool from markerless digital photography and verify its reliability. The study included 17 participants. Outer canthus–horizontal angle (OHA) and trapezius–horizontal angle (THA) were calculated from the image of the upper body of…

Detecting the Movement of the Pilot’s Body During Flight Operations

by Yung-Hsiang Chen, Chen-Chi Fan and Jin H. Huang

Advances in Science, Technology and Engineering Systems Journal, Volume 8, Issue 2, Page # 71–77, 2023; DOI: 10.25046/aj080208

Abstract:

This research presents a “Multi-camera for pilot’s cockpit measurement system”, which uses four multi-view images to eliminate the instrument and human body shielding and record the touched area. That could record the body reaction time (velocity and acceleration) and trajectory of the tested personnel. Real-time conversion of multi-view images corresponding to the 3D skeletal joint…
