Belgian Church Spire Scanned by a RIEGL Scanner

VZ-400i implemented into rejuvenation project

The Sint-Jan-De Doperkerk Church in Belgium recently retained LSBbvba to perform a 3D scan on the inside and outside of its historic chapel spire. The aim of this project is to capture data necessary for a renovation of the tower spire. Detailed façade plans and heights within the tower were needed regarding the stairs and bell levels, especially since parts of the spire were rotted and not safe for contractors to step through for observation.

A RIEGL VZ-400i Terrestrial Laser Scanner fitted to a tilt mount at a 45-degree angle was able to document the needed data, which was processed through RiSCAN PRO – everything being done completely from cloud to cloud.

“I have been using this scanner for almost 5 years but after hundreds of projects this was a challenge to scan. Little space and many repeating elements.” said Lieven Beuckx, Landmeter Expert at LSBbvba. “Still, as always, the VZ-400i delivered the desired result with a minimum of effort. Thanks to this project I now know that almost any project can be done with the VZ-400i.”
