Scan colourisation with iSTAR HDR images
The iSTAR 360 degree camera provides rapid, automatic HDR (High Dynamic Range) 360 imaging and can be used as a standalone device or for colourisation of point clouds created byspherical terrestrial scanners. Although Leica’s P40 scanner can provide internal HDR colour capture, iSTAR can be used to provide HDR imagery with more exposure steps and with reduced capture time. A project was undertaken to scan and image the Glasgow University Building, using both technologies, to show their combined capabilities. The results of the project showed that iSTAR provides the ability to efficiently capture HDR colour and accurately combine this with the scan data for significantly improved 3D visualisation and time saving.
