Résumé En

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.
