Et ce n&rsquo;est pas le cas des donn\u00e9es HD de l&rsquo;IGN. Nous allons donc voir ici comment transf\u00e9rer les valeurs de couleur depuis les pixels d&rsquo;une orthophoto vers les points correspondants du nuage de points LIDAR.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Pour cela vous avez besoin de votre nuage de points LIDAR et de l&rsquo;orthophoto ou autre image a\u00e9rienne de la m\u00eame zone.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Coloriser des donn\u00e9es LIDAR avec CloudCompare<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Dans ce chapitre nous allons utiliser CloudCompare pour r\u00e9aliser l&rsquo;op\u00e9ration.

Parce que l&rsquo;outil qui permet de faire cette op\u00e9ration dans LAStools fait partie des traitements sous licence payante. Vous pouvez quand m\u00eame r\u00e9aliser le traitement mais le r\u00e9sultat est volontairement d\u00e9grad\u00e9 par LAStools. M\u00eame si \u00e0 l\u2019\u0153il nu on ne voit pas de diff\u00e9rence, commen\u00e7ons par un traitement qui vous donnera le meilleur r\u00e9sultat est pour le meilleur prix (gratuit).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">De plus, le traitement avec CloudCompare est assez simple mais il vous permet de vous familiariser avec son fonctionnement. Vous serez alors \u00e0 m\u00eame d&rsquo;utiliser CloudCompare pour des op\u00e9rations plus compliqu\u00e9es.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a

Contrairement \u00e0 un SIG qui va d\u00e9terminer si deux points dans deux couches diff\u00e9rentes sont au m\u00eame endroit en comparant leurs coordonn\u00e9es XY, dans CloudCompare ce sera fait en calculant la distance dans les r\u00e9f\u00e9rences internes 3D. Quand on voudra affecter la valeur RGB d&rsquo;un point du nuage de points, il va rechercher le pixel le plus proche de l&rsquo;image. Mais comme on est dans un monde 3D, ce pixel n&rsquo;est pas forc\u00e9ment celui qui a les m\u00eames XY, c&rsquo;est celui qui a la distance XYZ la plus petite. Dans des terrains accident\u00e9s, cela peut \u00eatre tr\u00e8s diff\u00e9rent du r\u00e9sultat qu&rsquo;on obtiendrait avec un SIG.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Quand on a charg\u00e9 le nuage de points (voir l&rsquo;image plus haut) les valeurs de Z tournent autour de 589 m\u00e8tres. Notre orthophoto n&rsquo;a pas de coordonn\u00e9es Z, c&rsquo;est \u00e0 dire qu&rsquo;elle a des valeurs de Z =0. Si on laissait tel quel le d\u00e9calage Z (avec une valeur 0) on peut \u00eatre surs que les points les plus proches ne correspondront pas aux bonnes coordonn\u00e9es XY. Nous allons d\u00e9caler les pixels de l&rsquo;image d&rsquo;un d\u00e9calage de 589 m\u00e8tres. Les deux couches seront alors tr\u00e8s proches et les erreurs minimes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Si on rentre cette la valeur 589 on aura alors l&rsquo;image qui se situe au milieu du nuage de points.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/07\/image_et_nuage_dans_cloudcompare.png?ssl=1\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"640\" height=\"360\" data-attachment-id=\"11557\" data-permalink=\"https:\/\/www.sigterritoires.fr\/index.php\/qgis-pour-lidarcoloriser-a-partir-dune-image\/image_et_nuage_dans_cloudcompare\/\" data-orig-file=\"https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/07\/image_et_nuage_dans_cloudcompare.png?fit=3842%2C2160&amp;ssl=1\" data-orig-size=\"3842,2160\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"image_et_nuage_dans_cloudcompare\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/07\/image_et_nuage_dans_cloudcompare.png?fit=640%2C360&amp;ssl=1\" src=\"https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/07\/image_et_nuage_dans_cloudcompare.png?resize=640%2C360&#038;ssl=1\" alt=\"affichage lidar et orthophoto dans cloudcompare\" class=\"wp-image-11557\" srcset=\"https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/07\/image_et_nuage_dans_cloudcompare.png?resize=1024%2C576&amp;ssl=1 1024w, https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/07\/image_et_nuage_dans_cloudcompare.png?resize=300%2C169&amp;ssl=1 300w, https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/07\/image_et_nuage_dans_cloudcompare.png?resize=768%2C432&amp;ssl=1 768w, https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/07\/image_et_nuage_dans_cloudcompare.png?resize=1536%2C864&amp;ssl=1 1536w, https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/07\/image_et_nuage_dans_cloudcompare.png?resize=2048%2C1151&amp;ssl=1 2048w, https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/07\/image_et_nuage_dans_cloudcompare.png?w=1280&amp;ssl=1 1280w, https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/07\/image_et_nuage_dans_cloudcompare.png?w=1920&amp;ssl=1 1920w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><\/a><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Pr\u00e9-traitement de coloriser<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">On pourrait penser qu&rsquo;on a tous les ingr\u00e9dients n\u00e9cessaires \u00e0 notre op\u00e9ration de colorisation.
