A little local news:




State troopers learn animation to re-create accidents

With a few clicks of a mouse, Georgia State Patrol trooper Brandon Stone sends a blue Ford Taurus careening through a brown truck on his computer screen.

They don't quite collide yet, but Stone expected to learn how to make them actually hit each other later Wednesday afternoon.

"This is the first time we've actually put cars wrecking. You know, the cool stuff," he said.

Stone is one of eight Georgia State Patrol officers in the Specialized Collision Reconstruction Team who this week are finishing up training in forensic animation at Central Georgia Technical College in Macon.

At the end of their training, officers will be able to create animations and 3-D diagrams on a computer program, using evidence collected at the scene of a traffic fatality or crime. The animation can be used in the prosecution of cases to reconstruct a scene for a judge or jury, said GSP Sgt. Scott Short, support services sergeant for the reconstruction team.

"This is an illustration of our version of what the evidence tells us," he said.

For example, the animation could show how an occupant moved within a vehicle and suffered an injury, he said.

"Once our capabilities come to be known, we anticipate we'll get requests from GBI, from other local agencies (and) from prosecutors," Short said.

The Georgia State Patrol will be the only law enforcement agency in the state to have this training and technology, he said, and is one of few in the country with it.

"We're expecting cases from outside the state to come to us," he said.

Initially, forensic animation only will be used for traffic incidents involving fatalities, although later on it could be used in other cases. For example, it could demonstrate how a bullet moves through the body of a homicide victim.

The eight troopers in training are from offices in Forsyth, Valdosta, Calhoun and Athens. Each of those posts will be equipped with the necessary computers and software at a cost of $25,000 for each location, Short said.

Since January, officers have been receiving computer training from Central Georgia Tech instructors, learning how to use different editing and compositing software, said Jeff Cope, program chairman of the drafting department.

Last week, Sgt. Francisco Carrera, lead animator for the Illinois State Police, arrived to tie together all that work. Later this summer, Cope will train the officers for one week in 3-D animation, he said.

Illinois has been doing forensic animation for about 10 years and is a leading agency in the field, Short said.

The trend is slowly catching on, said Carrera, who received training from the FBI.

In "today's society, we're much more visually driven," he said.

This is due in part to big movie blockbusters with impressive special effects, he said. As another generation moves forward that is comfortable with computers and video games, he said, forensic animation will grow.

Forensic animation just now is starting to become more prevalent in criminal cases, Short said. Before, it was mostly seen in civil court.

Private companies already provide forensic animations for those who can afford it, but that often does not include prosecutors on a budget.

In one civil case, $100,000 was paid for three 15-second animation clips, Short said.

Stone said learning the animation is difficult but worthwhile.

"This week has made us a lot more comfortable to do this," he said. "We'll be ready to roll."

Who does the surveying of these accident scenes?

Who does the surveying of these accident scenes?I imagine they take photos after they respond...

FWIW, I know Jeff Cope at CGTC; they use 3dsMax. How they expect to learn and be productive in Max in 8 months is beyond me; I mean, the Max course they offer is a year, and it's not very in-depth - just basics.

So they are recreating accident scenes based only on photos? I don't see how that would hold up in court....

I have trained law enforcement personnel in using an earlier version of:
http://www.carlsonsw.com/PL_CS_investigation.html and equipment dealers would train them on using total stations and/or GPS

That is difficult enough. Many of them had never used a computer for anything more than typing notes in Wordpad. Getting them to use "autocad" was a challenge. I can only guess how difficult it was to train them to use the surveying equipment.

I've done some forensic animation for civil cases; I'd take pictures of the scene (well after the accident was cleaned up), then camera-match my scene with the photos, then add the cars crashing, etc.

It was more for visualizing what happened for the jury than actually proving what happened scientifically. It's a much better way of describing the accident than trying to explain what it looked like.

I actually do Forensic animation full time at my dayjob...and have for about 10 years. I actually think they should spend more time training them to do proper documentation of evidence....and leave the animation up to the experts. If this is a developing trend it would seem like an interesting avenue for freelance training.

Stusic...you don't have a copy of the curriculum for that MAX course do ya?

And actually just to clarify...photogrammetry/videogrammetry software and its output are very valid as well as admissible. I've tested it extensively and when done correctly it genereates the same 3d coordinate data as a total station. Mind you...you are limited to whats in the pictures/video but the information is valid....and you can setup markers in the scene to help.

Thanks for the info. That is good stuff :-)

If this is a developing trend it would seem like an interesting avenue for freelance training. I wholeheartedly agree with you. I've been working with 3ds for years and still don't know half the program...

I've really enjoyed the couple FA projects I've worked on, but I'd like to do some more. Wouldn't it be sweet to animate for the FBI???


Stusic...you don't have a copy of the curriculum for that MAX course do ya?Sorry, no anything left from school...
