Reconstruction Animations FAQs: What is Image Based 3D Reconstruction?

When you want to truly explain to your audience what happened, you need to show them not just tell them. This is the basis of all things relating to professional reconstruction animations. This is what we do best! 

For the last twenty years, the experts at the Evidence Room have developed ways to show your audience what is truly going on “behind the scenes” of the human body. This includes printed strategic exhibits, animations, storyboards, timelines, day in the life videos, legal photography, video services, interactive presentations, and more. These reconstruction animations are what makes it possible to visualize the key pieces of the puzzle for the students, judge, jury, or any other group of people  in order for them to see the big picture!

What is Image Based 3D Reconstruction?

In computer vision and computer graphics, 3D reconstruction is the process of capturing the shape and appearance of real objects. This process is done either by active or passive methods. If the 3D model in question must change its shape in time, this is referred to as non-rigid or “spatio-temporal reconstruction.” Our reconstruction animations take this concept to the next level.

The goal of image based 3D reconstruction is to infer the geometrical structure of a scene captured by a collection of images. Even still photographs only do so much to convince and explain the scenario to an audience. This is particularly true if your audience is of laypeople who don’t have legal or medical backgrounds, like in the case of a jury in a personal injury trial. In an instance of image based 3D reconstruction, our team takes several images (as many as possible) and uses them to create a 3D model.

Most often, we try to have as many images to build our 3D representation from as possible. The estimation of 3D geometry from a single image is considerably more difficult, since depth cannot be estimated and certain viewpoints may change the entire scene.

Useful Applications

As you may have guessed, there is a lot of complicated science and mathematics behind how this process works. We could tell you that in passive methods of 3D reconstruction, we do not interfere with the reconstructed object; we only use a sensor to measure the radiance reflected or emitted by the object’s surface to infer its 3D structure through image understanding. Probably what would be much more helpful is to instead tell you how and when these reconstruction animations are helpful.

Our professional surgical and medical animations are illustrated by experts and used in many situations where people suffer injury or death. Just a few examples include:

Police Officer Related Shootings

Motor Vehicle Accidents

Nursing home abuse

Premises Liability

Workplace injury

Other travel-related accidents

They can also be used for any other accidental injury or death. In essence, these animations turn the photos of the crime scene or images of a body post mortem into a much easier visual for your audience to comprehend.
