Erreur d'élévation du maillage texturé

Question

<\/HEAD>Ma première tentative de traitement de mes images de drone en utilisant D2M et d'ajout du maillage texturé résultant en tant qu'instance de <\/SPAN>IntegratedMeshLayer<\/A> à une <\/SPAN>Map<\/A> dans une <\/SPAN>SceneView<\/A> au sein de l'API js. Il semble que la couche de maillage soit affichée sous la surface mais reste visible. J'apprécierais si quelqu'un pouvait jeter un œil et voir quel pourrait être mon problème ?<\/SPAN><\/P><\/P>Merci d'avance pour votre temps<\/SPAN><\/P><\/BODY><\/HTML>

Anthony are there any tutorials on processing workflows for drone2map?

Thanks again for your help.

Thanks for the reply Anthony,

Is there a tutorial on the proper way to set ground control points? I believe im doing it right but not certain. I would place a point on the basemap in 2d mode then open up the image table and add the corresponding point to the drone imagery. I added about four different GCP's to the corners of the project area and matched 8 points to every corresponding drone image.

I reprocessed and ended up with a textured mesh that was slanted at almost a 45 degree angle lol.

Ryan,

Because of the inaccuracies of GPS systems on drones, and how this data is collected relative to the ellipsoid, this is actually very common.

The workflow to assure your meshes are at the correct (Orthometric) elevation, you will need to add ground control points around your project area and reprocess.

Thanks

Tony
