Photogrammetry options for a beginner?

MitchNC · Sep 3, 2019

Can anyone suggest free options for getting started playing around with photogrammetry now that we can run missions with the Evo?

3DF Zephyr - photogrammetry software - 3d models from photos

3DF Zephyr allows you to automatically reconstruct 3D models from photos. Zephyr is the perfect tool to capture reality: a complete photogrammetry software.

Most of them will give you a trial period that limits some pro options. I have never found that I needed pro options. Most of those option just slow down your computer.
These programs are not cheap if you went to buy them so make sure you really want to get into this stuff

I do use these apps to measure quantity, volumes, etc. So my company needs the pro version of the software. If you are interested to do pretty 3D renderings, then the basic version will do you good.

Nice program suggestion Ansia!!!

I just went through the 3DFlow Zephyr Lite tutorial. Amazing software.
I wonder if the 500 photo limit of the lite version is that much of a limitation.
The tutorial only uses 65 images and the resulting model is pretty incredible.

Yeah, I need to get out and fly today.

Not that we promote pirated software but yes there is a full version out there if you know where to look ?

I was looking forward to flying a mission today but the Explorer Mission app shows my location somewhere I don't recognize. Can't even find a familiar landmark.

When you try to create your mission. Is the drone connected and turned on? If not, the gps on your phone usually isn't very good.

MitchNC · Sep 4, 2019

No I was doing this without the drone because I just watched the Autel video.
I'll try it again tomorrow with the drone turned on.

You can do the mission planning without the drone on. Even if the phone has no idea where it is, when the app uploads the coordinates, they upload correctly. With the drone on and eith gps lock, it should make it a lot easier, if you don't know where you are.

MitchNC · Sep 5, 2019

Ok, thanks. I was just worried about it freaking out and flying away if it was confused.

MitchNC · Sep 6, 2019

I took the drone out and in GPS mode the Mission Planner still thinks I'm a half mile away, so I'm not comfortable using it.

Camera mode has my correct location, so I'm not sure why two functions within the same software aren't getting the same location.

Disappointed.

Try a different device todo the mission.

metashape app.

in the past, we had to create height maps with the tangent 90 degrees. and ariel photo to match. the height maps re-created by separate cameras and software which would run concurrently. the military today must have amazing apps probably blow any civy app out the water. if you realise the 3D extrusion and mapping down in one fly over. incredible

Agisoft broke my laptops battery.

MitchNC · Sep 11, 2019

Thanks, I'm downloading the demo now.

Does the Evo have a limit of photos taken in a Mission?
If you look at the picture you can see that it stops about one third of the way into the fourth leg of the mission.
I'm 100% positive that it came all the way back to the end point, because that's where I was standing. When it finished, it hovered and I landed it.

It took exactly 120 photos. Seems to be quite a round number.

Ha...yeah, just started it. 90% CPU.

Agisoft supports ATI. But CRAP...It starts at Radeon HD6000. Mine is HD5870.

I've done missions with 250+ photos. Largest I've done is one of 1700 photos, but that wasn't with an Evo.
