=====Utilisation=====
===en interface graphique===

File -> open +multi images->charger les pgm


sfm ->pairwise matching-> compute missing matches


sfm -> reconstruct sparse



selectionner les caméras qui posent probleme


bouton main grise  ?->delete selected camera


sfm->pairwise matching->show spanning forest    et matrix


bouton triangle rouge et bleu: compute 3D reconstruction


bouton cmvs=> choisir dossier /tmp/img sur ramdisk et donner un nom au fichier


view->dense 3D points





si il y a un problème lors du bundle à cause du choix des 2 images de références, relancer le bundle après avoir fait:
  
  Sfm->Pairwise Matching->Update Pairwise F-Matrix


sauvegarde du résultat en nvm ou ply

au cas ou il y aurait plusieurs modèles générés  
  Sfm->More options->Merge sparse model   puis relancer BA
  
  Sfm->More options->Find more points    puis relancer BA

pour afficher les correspondances entre les images: 
  View->feature match
  
  
  Resume 3D reconstruction peut enlever des mauvais matches
  
Imposer des paramètres intrisèques fixés:
  
  Sfm->More function->Set fixed calibration

    Start the GUI and listen to a socket port for UI commands,
    which simulate menu clicks. Each command should in the form 
    of "id[c][s] [argument]\n". The [id] is an integer that 
    corresponds to a menu item, for which the complete list 
    can be found in the sample ui.ini file. The optional flag 
    [c][s] corresponds CTRL and SHIFT press; The [argument] is 
    for the input string like filepath.

Meshlab

Filter→ Sampling / Poisson-disk Sampling.

La case Base mesh subsampling doit être cochée (car pour l'instant les éléments du maillage n'existent pas).
Number of samples: 10000
  Création d'un petit nuage de point contenant environ 10k points, en appliquant la méthode de rééchantillonnage vue ci-dessus. On applique ensuite sur ce petit échantillon 

Filter→ Point Set / Compute Normals for Point Set,

avec la case Flip normals w.r.t. viewpoint cochée8, et en entrant les coordonnées d'un point fictif éloigné du maillage (par exemple 0,0,-1000). 

Filters→ Remeshing, simplification and reconstruction → Surface Reconstruction : Poisson,

avec Octree Depth égal à 6. 
  Transférer ensuite les normales de ce maillage vers le nuages de points complets, avec 

Filters→Sampling / Vertex Attribute Transfer

en cochant uniquement Transfer normal, et en choisissant votre premier maillage (poisson mesh?????) pour Source mesh et votre nuage de points complet pour Target mesh. Il est possible de remplacer ces deux premières étapes en appliquant directement le filtre Compute Normals for Point Set au nuage de points complet, si ce dernier est suffisamment petit. Si le nuage est trop grand, l'application du filtre peut-être très longue ou faire planter MeshLab.

Filters→Remeshing, simplification and reconstruction / Surface Reconstruction : Poisson,

en choisissant Octree Depth entre 6 et 12 selon la précision du maillage désiré, et Solver Divide entre la valeur de Octree Depth et cette valeur moins 2.
 Attention le temps de calcul augmente très rapidement avec Octree Depth, et il vaut mieux commencer avec Octree Depth égal à 6 et l'augmenter de 1 en 1. L'effet de la valeur de Octree Depth est illustrée sur la figure 4. Sur cet exemple on voit le raffinement du maillage au fur et à mesure que le paramètre Octree Depth augmente9. A la fin de l'étape (3), on obtient donc le maillage recherché, mais il ne possède pour l'instant pas de couleur.

Pour transférer les couleurs contenues dans le nuage de point sur votre nouveau maillage, appliquez Sampling / Vertex Attribute transfer, en cochant Transfer color, et en choisissant votre nuage de points pour Source mesh et votre nouveau maillage pour Target mesh.

Filter→ Point Set / Compute Normals for Point Set,

avec la case Flip normals w.r.t. viewpoint cochée8, et en entrant les coordonnées d'un point fictif éloigné du maillage (par exemple 0,0,-10000). 

Problème, la moitié des normales est inversée….
