PPAP: Perspective Projection Augment Platform with Pan–Tilt Actuation for Improved Spatial Perception

open access: yesSensors, 2019
In this paper, we propose PPAP, an augmented reality platform with an actuated projector for dynamic user-perspective projection. In PPAP, a stationary camera is used jointly with a pan−tilt motorized projector-camera unit.

Projection distortion analysis for flattened image mosaicing from straight uniform generalized cylinders [PDF]

open access: yes, 2001
This paper presents a new approach for reconstructing images mapped or painted on straight uniform generalized cylinders (SUGC). A set of monocular images is taken from different viewpoints in order to be mosaiced and to represent the entire scene in ...

A New Pose Estimation Algorithm Using a Perspective-Ray-Based Scaled Orthographic Projection with Iteration. [PDF]

open access: yesPLoS ONE, 2015
Pose estimation aims at measuring the position and orientation of a calibrated camera using known image features. The pinhole model is the dominant camera model in this field.

APPLICATION OF DANDELIN’S THEOREM TO DRAWING CIRCLES IN PARALLEL PERSPECTIVE

open access: yesJournal of Industrial Design and Engineering Graphics, 2017
The paper analyses a problem of great theoretical importance in practice of perspective: the nature of the perspective of a circle from the horizontal plane according to the relative position between the spectator plane (parallel to the picture plane ...

TRANSFORMATION ALGORITHM FOR IMAGES OBTAINED BY OMNIDIRECTIONAL CAMERAS [PDF]

open access: yesНаучно-технический вестник информационных технологий, механики и оптики, 2015
Omnidirectional optoelectronic systems find their application in areas where a wide viewing angle is critical. However, omnidirectional optoelectronic systems have a large distortion that makes their application more difficult.

Application of Deep Learning Techniques in Water Level Measurement: Combining Improved SegFormer-UNet Model with Virtual Water Gauge

open access: yesApplied Sciences, 2023
Most computer vision algorithms for water level measurement rely on a physical water gauge in the image, which can pose challenges when the gauge is partially or fully obscured.

Sketching space [PDF]

open access: yes, 2000
In this paper, we present a sketch modelling system which we call Stilton. The program resembles a desktop VRML browser, allowing a user to navigate a three-dimensional model in a perspective projection, or panoramic photographs, which the program maps ...

A CONTINGENCY THEORY PERSPECTIVE TOWARDS PROJECT MANAGENEMT CONTROL SYSTEM

open access: yesThe Journal of Social Sciences, 2020
Bir projenin başarısı esas olarak maliyet, kapsam ve işgücü gibi değişkenlerin titiz bir şekilde planlanmasına bağlıdır. Proje yönetiminin önemi son zamanlarda hem küçük ölçekli işletmelerde hem de büyük çokuluslu şirketlerde büyük önem kazanmıştır ve bu da proje yönetiminin kurumsal performansın kritik bir bileşeni olarak görülmesine yol ...
