| Abstract: | The Department of Geomatics and the Regional Centre for Innovation in Engineering Design in the University of Newcastle upon Tyne collaborated in a project to produce precise measurements for use in the fabrication of the body of the "Angel of the North" sculpture. This 20 m high edifice, by the sculptor Antony Gormley, is located adjacent to the A1(M) in Gateshead, Tyne and Wear.
This paper reviews the photogrammetric reverse engineering work carried out on a 1:10 scale plaster maquette of the "Angel of the North", which is a life-size model of the sculptor's body without any arms. The three dimensional measurements of the maquette, made by analytical photogrammetric techniques, were then processed to produce a fully functional three dimensional CAD model from which the dimensions needed by the fabricating company, Hartlepool Steel Fabrications Ltd., could be extracted. Additionally, the VirtuoZo digital photogrammetric software package was used to investigate the potential of automated measurement for this type of work and the results were compared with those obtained analytically. |
