Building on the extensive research in Virtual Reality (VR), we are proposing a new dynamic prototype for modelling and simulating carbon emissions in a virtual village called VIRVIL. VIRVIL is a simulated settlement for the assessment of the impact of low and zero carbon technologies and measures in the built environment. The prototype will focus on the impact on the community as a whole, as well...
The objective of camera calibration is to establish the relationship between 3D world coordinates and their corresponding 2D image coordinates. There are various kinds of control points used in the calibration procedure. However, many of them are too sensitive to the thresholding error. Circular control points do not have this problem but they need to be corrected the distortion caused by the asymmetric...
An intensity modulated fiber-optic position sensor, based on a fiber to bundle coupling and a readout system using a CMOS image camera together with fast routines for position extraction and calibration, is experimentally demonstrated. Further, a simulation of the complete sensor system setup is made, and possible sources of error are analyzed experimentally. Our analysis indicates the theoretical...
