Colourcloud Set to Transform Laser Scans with Fast Point Cloud Colourisation Overlay

March 4, 2015—NCTech Ltd, creators of the ground-breaking iSTAR 360° panoramic digital imaging device, is launching ColourCloud, the world’s fastest automatic HDR point cloud colourisation software. This offers speedy, pixel-perfect overlay to support iSTAR files and e57 industry standard laser scan outputs from leading scanner manufacturers including Trimble, Leica Geosystems and Faro.

This now means that HDR images are captured at each scan position in just 20 seconds and the ColourCloud batch processing capability reduces post-capture scan colourisation to a fraction of the time normally taken.

The ColourCloud process provides fully automatic colourisation which speeds up workflow rates, requires no stitching, resolves parallax issues and is precision calibrated to sub-pixel accuracy. The end result is full colour HDR overlay from any laser scan to within +/-2 pixels.

Neil Tocher, Chief Technical Officer of NCTech Limited, explains the concept and development of ColourCloud:
“ColourCloud™ is designed to use a single open file format to integrate into the existing output from software across all manufacturers scanning devices and is a significant improvement on existing processes which can take a professional considerable time to colourise a single 3D scan from a scanner.

This means that hundreds of millions of 3D scan data points can be colourised from an iSTAR® image in seconds. We are redefining the colourisation process with total automation in a fraction of the time it currently takes."

As a comparison, NCTech Limited highlights an example in which the iSTAR® camera captured a 50 million pixel image within 20 seconds; the same resolution scan (without colour) would take around 20-30 minutes.

A high dynamic range capture of up to nine exposures takes just over two minutes with iSTAR®. This is a fully automatic process, done at the push of a button.

NCTech Limited's CEO, Cameron Ure, adds:
“This is a significant milestone in offering the laser scanning market an innovative step-change solution, whilst delivering a leap in visual quality and detail.

It not only saves time, but seamlessly assists the entire workflow and the ability to automatically colourise an entire point cloud. This is ground-breaking for the laser scanning industry.”

NCTech is a pioneering immersive imaging company based in Scotland and founded in 2010 by Neil Tocher and Cameron Ure. The company launched its first product, the iSTAR®, a fully automatic instant 360o panoramic camera, in the spring of 2012.

Originally developed for the military and police, this new type of rapid reconnaissance camera is predicted to displace current technology and has multiple applications: from covert operations and police reporting of crime scenes to 3D laser documentation and asset management for the engineering and heritage sectors.

iSTAR® is the first camera to have the power to process its images internally, with no need for a computer to complete post-production processing or stitching. Small, light and robust, it is easy to transport, quick to set up and does not need special training or photographic skills.

Originally self-funded and still privately held NCTech recently received investment from business angel syndicate Archangels and is listed on the Scottish Enterprise high growth stream.
