The virtual reconstruction of the minaret of Mansourah mosque (Algeria)

This contribution synthetically addresses some of the photogrammetric solutions available today in the field of architectural-archaeological survey and the related applications outcome, evaluated during both the acquisition phase of metric data than in those of effective yield of refunds infographics. Therefore, we have focused on the virtual reconstruction of one of the most emblematic and symbolic building of the Algerian culture, the mosque of Mansourah, returning the minaret as it appeared before its partial collapse, namely correspondent in geometry, textures, and colours. The work is part of a larger research project to promote knowledge and dissemination of Algeria cultural heritage, with 'original' approach about the validation of an integrated methodology. In particular, the analysis has led to the application of the theory of errors on the survey of the elevations obtained by the two different methods of photogrammetric survey, multi-image and stereoscopic. The documented example shows how it is possible to achieve reliable reconstructions of each structure, although presently destroyed, bringing to light traces of a story now lost
