Knock out Aerial Drone and super tough SU Challenge

Now it is a proven workable workflow with manageble and predictable results.
Forgive me but...workflow for what?....and can you show us the result?
When you spend your entire modeling career fighting with heavy terrain and someone comes along with a drone that is part of the solution...seems like too much fun to me.

There is also a workflow for the less expensive Parrot Bebop:
Nowhere near as advanced as the DJI Inspire 1 but similar results and more than 5 times cheaper. I am not even trying to compare them as the DJI is a different league, but if you want "cheap" 3D terrain mapping then the Bebop is pretty awesome.

They also used drones to 3D map the Matterhorn in Switzerland:

This is incredible. Years ago I was following the blog of a kite photographer who worked with a research team at University of California to map one tower and it seemed so cool, and also so far away from being something that others would be able to do.

This is great, didn't think anyone else has been doing this. I've been flying the DJI Phantom 2 Vision + along with Pix4Dmapper for about 10 months. I have access to Trimble GPS and robotic total station so my models are georeferenced but I've been able to do some comparisons also and it's surprising how accurate this workflow is. I have point clouds created this way with Pix4Dmapper that are within a couple tenths horizontally and vertically of survey grade and can cover a much larger area in about a quarter of the time (including processing time in Pix4Dmapper) than an actual field survey . Below a screen shot from Pix4Dmapper of a recent flight.
Ps
By georeferenced I mean to State Plane grid as it's already georeferenced from the photo gps tagsMike

Roland - Here is the resulting SKP Model. Let say if the work flow is polished up from the time you step out of the office to take pictures (minus travel time) to the moment you get model like that is 2 -3 hours safe.

I really must stop reading this thread before my bank account takes a hit.

I must just be dumb cause I still have no clue what the workflow is for.
I see the cool image but it's resolve is very poor.
"workflow"? sure you didn't just mean "playflow"

Roland, I don't have the model with me now, but it is pretty similar to what Rich posted.
Can you be more specific about what you are looking for? Witch piece of the puzzle are you missing? -
I think what roland joseph is referring to is that your model is not very defined, I know for a fact that you can get much better results with this workflow, unfortunately I can not post any of my models but here is a link to a video by the Pix4Dmapper team.

And here is the 3D model

Thanks Denis and alpro...I get it now....cheers!

1.5 years later. Look what I am doing with photogrammetry now.
The 1st picture is almost a square mile. then zooming to a random detail.
It is all light and moving fast. no overloading PC anymore! the future is here!
Just to get a kick -scroll these pictures up and down a few times.
-
Impressive result!
-
Woah, crazy level of detail ! I'm really interested in getting myself a drone too. Any chance you explain your workflow ?
-
There is no secret. It is just photogrammetry tools gotten that good. Take thousands of photos, dump them in,a few days later get the result.
