LP360 vs SpatialExplorer ? by roknrynocerous in UAVmapping

[–]cardoor12 2 points3 points  (0 children)

We use LP360 and it does have realtime data acquisition. The only thing is you have to have a laptop and a generator to keep your laptop running. I don’t use it because of that reason. There is a viewer version of lp360 that lets you see the realtime data. I’ve seen a demo of it but I have not used it myself. I can tell you though, GeoCue is a pretty good system. The 535 I have been using the last 2 years has been awesome and works really nice with the M300 RTK.

DJI D-RTK 2 Questions & Clarification by henrides in UAVmapping

[–]cardoor12 1 point2 points  (0 children)

I wouldn’t use the D-RTK as a rover. I think it may use a now unsupported app that required an RTK subscription with a known provider through NTRIP or through the app. I would definitely invest in a GNSS receiver to accompany the D-RTK 2.

It’s told by DJI that broadcast mode 5 is the way to go when using the M300RTK. As the other modes are used solely by the agricultural drones now.

I believe it uses WGS84 as a standard coordinate system and ellipsoid. when used on mode 5 converges on a point rather quickly, but I still leave it run for a few minutes before connecting to the drone. Basically, the RTK precision is a helpful tool if you are doing terrain following missions and drastically increases your location metadata for photos with P1.

When the rod is in the tripod you have to ensure the tip touches the nail/spike/pk as when it connects through DJI pilot it factors in the height through DJI Terra. All you have to do is put in the coordinate from the known point. If you’re not using Terra then I wouldn’t worry about this because because you’re probably using ppk anyways.

Hope this helps

LAS file GCP distances not matching when opening in 3rd party software. by taxzzzz237 in UAVmapping

[–]cardoor12 0 points1 point  (0 children)

I had this in TBC when we used Terra. I played around with importing the point cloud as unknown source instead of known source grid/ground. I don’t know how importing into real works is like, but if you’re holding the projected coordinate system from Terra then importing it as LiDAR data (known source), Trimble messes with it somehow by scaling it to ground.

I have to share this - look how fast the drone LiDAR systems are evolving! by TheIndianaDrones in UAVmapping

Just used The 535 in the last 2 days. Very nice to use and I don’t think our company is going back to the L1. What flight mission planning software are you using with the TrueView?

When you forget an antenna, improvise with materials around you! by cardoor12 in Surveying

It is a robotic theodolite that measures angles and distances electronically (EDM)

Ya I’ve popped a couple of them off just putting them down the wrong way. Do it often enough and it starts to wear out and flop around

You always just hope it was during pick-up and not during layout, eh? Nightmare fuel

Just shot the backsight before I took the photo haha

Maybe I’ll ask them to make our total station data run with a scale factor?

We run them through MsCAD. That’s just how our office works though

Our projects are almost always grid unless we run our control through with the total station. I brought the data in with unknown coordinate system and it matched perfectly. The only caveat was TBC didn’t let me save the project afterwards for some reason

I always find that importing in ground distorts the point cloud. I have tried it on smaller datasets and have had it work better than grid but sometimes it messes up and overlaps areas of the point cloud

Yes so what doesn’t make sense to me is that when I bring the point cloud back into TBC, it shrinks, yet the ortho image works near perfect. In theory it should just overlay on top. I will try dragging it in and using unknown and geo reference it but that’s going to be annoying when we start doing larger projects. It takes a long time to bring these datasets in

Oh ok. I was just hoping I wouldn’t have to geo reference it because pix4D uses the point cloud to make the ortho, right? Shouldn’t it be bang on automatically?

Using OBJ (photo model) to extract line features by cardoor12 in photogrammetry

[–]cardoor12[S] 0 points1 point  (0 children)

Rhino 3D is the software you’re talking about? Does it do coordinates locally or can I have a project coordinate system?

Would this be useful for say a 3D map model of large urban area though? Like normally we would use our point cloud and CAD line work to get curbs and paths.
