This digital health record aims to provide a basis for scientific monitoring and planning of restoration work by referencing data (mapping of deterioration and architectural and historical archives) on a Web-based documentation platform. The starting point is building a 3D model of the monument. This 3D model must meet specific requirements for its subsequent use, including the ability to be unfolded in 2D with visual consistency. The method to be used for 3D acquisition depends on a balance between speed of execution, cost, and compatibility with respect to data organisation. This paper presents a comparative study between photomodelling and laser scanning. The different steps needed to build a reliable 3D model with both techniques are demonstrated along with a critique of the advantages and disadvantages of each.
