Estou querendo fazer uma modelagem 3D de uma casa. Estou querendo alugar um drone para conseguir as imagens. Gostaria de saber se é possível realizar fotogrametria através do SketchUp ou a partir de uma imagem gerar este modelo 3D. Desde já agradeço a atenção de todos e tenham um bom dia.
I am wanting to do a 3D modeling of a house. I want to rent a drone to get the images. I would like to know if it is possible to perform photogrammetry through SketchUp or from an image generate this 3D model. I thank you all for your attention and have a nice day.
Yes you can do this but you need specific software in addition to the the Drone and SketchUp. I’ve used 'Drone Deploy’ which is not cheap. See previous post about the process of getting it into SketchUp as Drone Deploys creates a .obj file which SketchUp current’y doesn’t ready natively. https://www.dronedeploy.com/
Now that Skimp and Transmutr exist, you can skip the Blender step unless you’ re looking for a free way to convert and/or import to SketchUp.
Actually, as I’m starting, I was looking for something free and within SketchUp, so I asked if there was any way to do that inside the software itself. At first I would not want to use ancillary software. Sometimes there is some video or tutorial helping or even some SketchUp plugin.
I found it much easier to save the whole model as an .las format point cloud file from Agisoft and importing it with Undet for SketchUp. Then you can do all the necessary detail extraction inside SketchUp.
Agisoft would also allow to combine drone shots into one high quality orthophoto to project on to the terrain in SketchUp.
It seems to be a very interesting option. I just don’t know if I’ll have time to learn it. I’ll focus on the Sketchup tool that you mentioned in one of the comments, if it doesn’t work out I’ll try Agisoft and Pix4D. Thank you for your help.
Thanks Dale for the shout out. Here are some videos. The first video shows examples of 3D drone mesh imported into SketchUp. We used Skimp to import the data (I am not associated with Skimp). The data was created using a drone collecting photogrammetry, processed in Pix4D and imported into SketchUp using Skimp as an OBJ format.
The other video are work examples spanning two years. We use the drone images + SketchUp, Lumion and Photoshop and create these dronematches or photomatches. We do a good amount of these now. Not always easy to do. They take some practice and really getting the right angles. Lumion has an image overlays filter which helps a great deal. But end products require Photoshop.
I will be publishing a book on this next year with Jon Altschuld. The book has been given to Wiley and we are in the production part of it all now.
