Application of Photometric Stereo to the Study of Rock Art in Chauvet Cave

Résumé

PS offers several advantages for the reconstruction of cave walls, particularly its ability to digitizeuntextured surfaces, to estimate both the relief and colour of a scene, and to process data quicklyin a parallelizable manner, while preserving the resolution of the input images. However, thistechnique has its limitations. Indeed, the result obtained is a normal field, which can beintegrated into a depth map, but this does not constitute a true 3D reconstruction. Additionally,the method relies on the Lambertian assumption, which is not always valid.
