iSTAR & FARO Focus 3D X130

Scan colourisation with iSTAR HDR images

The FARO Focus 3D X130 scanner does offer colour capture but is limited to single exposure, not HDR. It therefore does not always provide adequate results in challenging lighting conditions. NCTech iSTAR cameras can be used to provide HDR imagery for improved performance and reduced time on-site. NCTech ColourCloud technology is integrated within Faro SCENE from version 6.0 and the NCTech ColourCloud app can be downloaded free of charge from FARO 3D App Centre. Using the ColourCloud app integrated into FARO SCENE further streamlines user workflow by enabling automatic point cloud colourisation and import of iSTAR images without needing to leave the SCENE workflow environment.

Low light conditions

iSTAR advanced HDR capability challenging lighting conditions

The iSTAR 360 panoramic camera provides rapid, automatic High Dynamic Range (HDR) imaging in challenging lighting conditions, whether in environments with high contrasts of dark and shadow, or low levels of ambient light. The NCTech iSTAR camera can be set to capture a single exposure (HDR OFF), five (HDR ON) or up to nine exposures (HDR PRO) automatically with an equivalent range of up to 27 f-stops. The whole 360 scene is automatically analysed to establish the most suitable exposure values (EV) and bracketing to cover the scene’s dynamic range. In this example images were taken with and without using HDR to show several challenging light environments in which iSTAR HDR capabilities make a significant difference in image capture quality.

iSTAR Measurement Module

Accuracy testing of the iSTAR Measurement Module
