Drone Mapping Guide | Part 4

[@dwade_fpv]

These guides are great. Thank you so much

grear work, and thank u for all that effoert

[@khanhminh7110]

Great video, can you guide me on how to create a flight plan for Phatom 4, thank you very much

[@CapturingReality]

You just need to download an app for that. I suppose there are more suitable.

When I export the point cloud, following the video, I don't get an .las file, I get an DWG Trueview Layer State. When I open it in Cloud Compare I get a thin straight line of colored dots. Is there a setting I missed?

how does the final deliverable data compare to Drone Deploy?

im trialling RC for use in my small business - drone surveying with M3E. im loving the interface and its a huge leap up from my current WEBODM and QGIS combo in terms of functionality and useability. I have one slight issue - is there any way to export an ortho with the stockpile volume shapes and quantities overlaid? i need this for client issue (the whole project is based around giving them the data to be able to manage material stockpiles on site). previously i have been using QGIS for this element of work - RC is far slicker to work with in comparison but i cant see how to achieve this. i considered exporting the JSON but i think it needs to be GEOJSON to be able to then be imported into another package. nothing seems to want to touch the JSON. the alternative is to sketch on the stockpile locations in cad, but this is duplication of work. any help or advice welcomed.

[@CapturingReality]

Hi, you are right, this is not possible. You need to use 3rd part application to do it. Or you can export the ortho report, where this will be implemented.

[@GJBUAV]

@@CapturingReality thanks for getting back. are you saying that if i export the ortho the shapes will be overlaid?

[@CapturingReality]

@@GJBUAV No, you need to export ortho report to see it there.

[@glynbarrett1961]

@@CapturingReality got it thanks. anyway of getting a higher res output? i need to drop that very view into an autocad drawing but it needs to be higher res. could this be something that could be added as an option?

[@CapturingReality]

@@glynbarrett1961 In higher resolution only the clean ortho can be exported. If you wish I can add this as a feature request for you.

[@Rogun987]

When I try to export the LAS file I do not have the option to export PROJECT OUTPUT for coordinate system. I setup my coordinate system in settings in the beginning.

[@CapturingReality]

To use the option Project output you need to have georeferenced project. Do you see the pin icon next to your component?

[@Rogun987]

@@CapturingReality Thanks for the reply. I figured it out. When I brought in the ground control, i used "add control points", it added NEW points and not under the points I brought in. Even though In 1d I had the imported point selected, it would add a new outside the imported points. So I just ended up manually adding points thinking they were part of the imported GCPs but they were not, obviously.

Hello I watched all four of your videos. I thank you for your videos. I created a model with an obj extension by watching your fourth video. The model size is about 6 GB. Is it a problem that it is this big? I am trying to open it in the cloud compare software. But cloud compare runs for a very long time but does not respond. What should I do to reduce the size of the created model? Probably when the model size is reduced, the model precision will decrease. I am waiting for your suggestions. Good luck

[@CapturingReality]

Hi, I suppose it depends on your needs, but such model could be too big. There is a tool called Simplify Tool, so you can use that to reduce the size of your model. The precision could decrease, but it depends how much you will simplify your model. In general, this decrease won't be so long (it also depends which precision are you considering).

[@inceemreince]

@@CapturingReality Hello, Thank you for your quick response to my question. I tried what you said right away. I want to ask another question. The number of triangles forming the model decreased with the Simplify tool. I immediately created a new 3D model with an obj extension from the newly formed model. Its size decreased to 1.2 GB, but when I opened it in the cloud compare software, all the objects on the model were created only in white. Where could I be making a mistake? or what should I do?

[@CapturingReality]

@@inceemreince Is your model textured? If so, was it exported as with textures? I tested this and the textured model is colored in CloudCompare.

[@inceemreince]

@@CapturingReality I realized I didn't understand the subject. Please excuse me. I will ask another question. I exported the model I created with the process steps you explained in the 3rd and 4th videos in obj format. The 6GB model was opened in Cloud Compare software, albeit late, and it was in color. I subjected my model under Component in the 1D image in the Reality Capture software to the Simplify process as you said. I selected my new model with less triangular surfaces and converted it to a 3D model in obj file type. The image appeared white in cloud compare. In order for the 3D model to appear in color in Cloud Compare, will I apply an additional texture process to my new model created as a result of the Simplify process? Or will I need to change a setting during the export process from the new model with the 3D obj file type?

[@CapturingReality]

@@inceemreince Basically both. You can use the texture transfer during simplification, you can reproject the texture on simplified model and you can also create new texture. Also, you need to set that you want to export the texture during mesh export.

[@bzzzogm]

Can you explain more about the vertical coordinate system? After I loaded the obj or las into ArcGIS, the height looks incorrect.

[@CapturingReality]

Hi Brandon, were your data georeferenced? In RealityCapture are used ellipsoidal heights.

[@bzzzogm]

@@CapturingReality Yes, the data is georeferenced. The point cloud exported are in the right location but the wrong height. For example, the model's elevation display range is between 1-3m, instead of the drone photo sources 100m.

[@CapturingReality]

@@bzzzogm Did you used GCPs for georeferencing or just images?

[@bzzzogm]

@@CapturingReality Just image, I thought it might be the issue, not sure if the software can auto calculate the true height without GCP.

[@CapturingReality]

@@bzzzogm When you are using drones, the height is not above sea level but about place of take off. So there could be these differences.

[@arthurrousseaux2800]

Hi, any chances to export all the regions and so on volumes ?

[@CapturingReality]

You can do this using reports.

[@juu226]

Is there any way to import dxf with a map on created georeferenced model?

[@CapturingReality]

Hi, what exactly do you mean by map?

[@juu226]

@@CapturingReality Thanks for response, it is quite old tutorial. I meant for egz. my created dxf file with boundaries of planned excavation. I managed to workaround this by importing those boundaries as GCP points but measurment tool is not clipping to them so it is a bit tricky to set up exact place for calculations on created model.

[@CapturingReality]

@@juu226 Hi, for this you can use reconstruction region (export and use it later). But there is also possibility to export shapes (in Ortho mode) and use those shapes in volume measurements for example.

[@juu226]

@@CapturingReality Ok thanks, I will try that. Hope in future there will be some possibility to export chosen points xyz coordinates from point cloud as txt file for land surveyors. Something like addnotations on Recap pro.

[@CapturingReality]

@@juu226 This is possible to do. forums.unrealengine.com/t/export-control-points-with-xyz-coordinates/682566

How to export as a 3d video?

[@CapturingReality]

Only 2D video can be exported from RealityCapture.
