IAFSM 2017 Conference Images

Post by 3DForensics » Wed Nov 01, 2017 12:43 pm

Hey Everyone,

We've been so busy at the conference here in Atlanta that we haven't had a chance to post any images. We have great attendance this year with people from Australia, New Zealand, Canada, England...etc.

I will be posting some images of the activities here as best as I can.

Here are some shots from Day 1 Workshops

Yesterday we ran our group workshop where we ran a Clandestine Grave Excavation and a mock Collision. Lots of "toys" at this event and the weather was just perfect.

A couple more photos.

Grave modeled in PhotoScan and then imported into 3ds Max as an OBJ model.

While many of the attendees were 'playing' in the dirt we set up some cars in a mock crash site, with a body. One of the cars is David's new ride.....I'll let people guess which one!!!

I rented the mini-van and requested a black vehicle to make it interesting. Helen, from Eugene's company, suggested that I could use dry shampoo to spray some powder on the vehicle.....I also found some athlete's foot spray powder. Helen and I powdered up the mini-van...and left some areas free of powder.

The powder did in fact help. On the shadow side of the mini-van it was so shiny that the software I used (Pix4d) had trouble creating a surface there. I have not really played with the settings to see if I could get that surface to generate. If I was going to try I would put some control points on that side of the van.....but it is so shiny you basically see whatever is being reflected at the moment and it would be difficult to find matching points in different photos.

Mark Johnson flew the area with his DJI P4P and then I processed the images, added a few control points here and there (none on that shadow side of the mini-van though).

Interesting exercise. Mark showed some great flying skills and also demonstrated some of the techniques he taught in his Monday workshop...great job Mark.

I'm attaching the ortho-mosaic, which I think is really good. I'm also including 3 screen shots from Pix4d of the mesh that was created. David's Vette was shiny metallic grey and the mesh is pretty 'wrinkled' on those surfaces. If I was going to try and clean it up, again I would start by adding some control points on the various surfaces. Mini-van came out reasonably well, it is cleaner where we sprayed the powder on.

The glass and lamps on the mini-van benefited from the spray powder....you can see where there was no powder. For some reason David would not let us spray powder on his car and you can see ripples in the shiny surface as well as a huge hole in the windshield.

I know several people also scanned this scene. I hope they'll post results as well.

Well done! I really appreciated all the effort you put into setting up that scene. And thanks for the ride back to the hotel!

Great pic. Good day for all and lots of discussion as the scans went on... Now, a collective name for scanners in that array?

It is a capital mistake to theorize before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts

Actually, I would say it was more like scanners playing together. It really was!
