obj file, as well as materials and texture in the project folder that Pix4D has created. Now import the 3D model you created with Pix4D. I am already in the 3D visualization of PV*SOL premium and have started a new project there. Now open PV*SOL premium 2018 or a higher version! You can see that the 3D model is already close to the Google original. I just want to view the triangulated mesh and disable the other elements. If you want to view the mesh, you must first activate "Triangle Meshes". ![]() Now the 3D model is already complete and can be viewed. Next, the triangle mesh can be generated. Place the ends of the 3D arrow at a distance you know to be parallel to the height axis. ![]() The "Orientation Constraints" function is used to correct the alignment and inclination of the model. Here you can see a completely unnatural slope which has to be corrected. Unfortunately, the program sometimes has difficulties in determining the correct position of the model from the screenshots. The result now shows the reproduced positions of the camera and the tie points. Here you specify that this file is to be created in obj format. You can achieve this with the decimation strategy "Sensitive".Ī model file is automatically generated after photogrammetry is complete. The maximum number of triangles has to be limited for the level of detail, because PV*SOL premium currently only accepts 3D models with a maximum of 500,000 points. The maximum "Texture Size" should be 4096 pixels. I want the textures from the screenshots to be transferred into the 3D model. I leave the settings unchanged.Ī few things have to be adapted to the mesh options so that the 3D model can be imported correctly into PV*SOL premium later on. You can experiment a little later on with the settings for the "Point Cloud" to get an even better result. Make sure that "Keypoints Image Scale" -> "Full" is selected. I leave the general process options unchanged. Before I click on "Start", let's first look at the options for this.Ĭlick "Process", and then click "Process Options".Īt first, only the settings for "Process" and "Point Cloud and Mesh"are interesting. This is not interesting at the moment, because there is no geoinformation in the pictures. Select the menu item "3D Models" and then click "Finish". On the last page you can see an overview of the level of detail expected for the finished 3D model and how long the creation process will probably take. The following pages are currently not interesting. Here you can now see an overview of the geodata and the camera model, which were determined from the images.ĭue to the fact that I made screenshots, not much data is included. Now select all screenshots with "Ctrl-A". In the next step the screenshots will be added. You can currently download this program as a 14-day trial version by creating a customer account on:Īfter you have started Pix4Dmapper Pro, you will be taken to the "Home" page of the program. In some photogrammetry programs it is useful to take some close-ups as well.Īlso move the mouse out of the picture before creating the screenshot, so that the mouse cursor is not visible in the picture!Īfter you have made the 30-40 screenshots, start Pix4Desktop. The more images that are created from different perspectives, the better the 3D model created later on will be. and that the pictures are not too twisted. that potential additional shading objects are visible, that the target building is always completely visible, ![]() 8 pictures from different angles of the bird's eye view 12 pictures at the height of the ridge or the highest point of the building. In order to achieve an optimal result with photogrammetry, all labels and menus should be hidden first. In the next step I will take about 30 - 40 screenshots of the scene to create a 3D model in Pix4D. The measured length of the edge is approx. To do this I use the ruler function of Google Earth and draw a 3D path to an edge that is well visible. This is later used in PV*SOL to reproduce the scale. Here I enter the coordinates of the object.Ī 3D model is to be extracted from this object.įirst, I determine the size of an edge of the model. Import of the 3D model into PV*SOL premiumįor this video I chose a free-standing, relatively complex building in England. Extract Google Earth 3D models with Pix4D and PV*SOL premium 2018ġ.
