National Gallery Projection Survey

The National Gallery celebrated its 200 year anniversary earlier this year, and big celebrations were planned! Our friends at Creative Technology were commissioned to project a video onto the front of the building to entertain the visitors to their NG200 event, and we were commissioned to survey the front facade of the Gallery and provide a 3D model to enable the mapping of the video projection.

Due to the intricate detail on the building exterior, extremely high quality point cloud information was required to enable an accurate and detailed 3d model to be produced. Normally the level of detail required from the model will depend on the type of content and elements of the building that the client wants to pick out in the projection, and as this particular projection targeted individual string courses, a high level of detail was required. 

To scan the building we used a Leica RTC360 laser scanner with high accuracy tilt enabled. The data was then cleaned and registered in Leica Reg360 and the resultant point cloud was then modelled in Rhino, delivered to Creative Technology ready for mapping. ​

"A truly professional service provided by Grantham Coates Surveys. Having now worked with them for many years on numerous Projection Mapping Events they always provide us with highest quality scans and models for our projects. They are very easy to deal with and will always go above and beyond to try and fit in with the tightest of work schedules."
