We deal with forensic reconstructions , o forensic animation on the basis of an experiment or for research purposes.
We give technical support for investigations or judicial examinations with the same technology that we use in the fields that are more congenial for us, such as the digital processing of images in motion.
We created the first virtual simulation admitted as evidence in support of technical expertise in a courtroom under the guidance of the consultant for the civil party, Giancarlo Forte, in 1994. (Court of Parma 12-12-1994).
Under the guidance of Prof. Fabio Dossi in 1999, we built our first virtual reconstruction admitted in a courtroom of the visual capacity of a person suffering from deficit. (Court of Assise in Novara 1999, Court of Appeal in Turin 2001).
We have been developing supporting technologies for forensic analysis to:
- improve the analogic, audio or video, static or dynamic, signals
- reproduce virtual or actual scenes in 3d
- identify tampering or alterations of digital supports.
Every type of recorded image (static or video) that comes from video surveillance systems, amateur cameras, mobile phones, web platforms can be improved and made useful, if not essential, for comparisons or insights.
The degree of improvement is affected by several factors, such as the technologies chosen and the method by which images are processed.
In the case, for example, of the examination for the Court of Appeal in Turin (2011), in order to make comparisons between images that were apparently unreadable, we isolated limited sections of the same sequences that presented the best features.
On other occasions, we have faithfully reproduced episodes to be analyzed,filming them and then comparing them with the results of digital images.
Every investigation is an episode in itself, and should be treated as such, integrating different software and technologies. There are then also 3D or virtual reconstructions, divided into three-dimensional simulations or representations.
The simulation starts from an objective reconstruction, faithful in every way, and goes on to show what cannot be seen or viewed with traditional techniques.
The representation, however, shows an event or a thesis so that it may be better understood. Both techniques do not solve anything on their own, but they show, deepen and possibly even help to prove the conclusions of the experts such as:
- public prosecutors,
- engineers, surveyors and technicians.
It all starts with the construction of a three-dimensional model of of the site in question, which corresponds in all respects to the correlative reality.
Then we proceed to build, in three dimensions, objects and subjects in the scene.
Each element can then be moved according to the information, in a binding way, obtained from the documentary material.
We can thus observe the scene from multiple points of view, such as those of the parties involved, witnesses or defendants.
This method is particularly effective for activities such as:
- Assessment of the evidence and different versions of the defendants.
- Kinematic analysis of accidents: road, air, sea, structural.
- Analysis of dynamic and kinematic events.
- Ballistic analysis.
- Analysis of the medical practice.
- Analysis of manufacturing defects.
- Analysis of accidents.
One technique does not exclude the other, on the contrary.
Today thanks to the wide use of video surveillance systems, which are found both indoors (such as banks or supermarkets) or outdoors (such as in parks or on the streets), it is possible to reconstruct really and virtually, using all the recorded images collected, events and dynamics and to identify involved subjects and vehicles always in relationship to the quantity and the quality of the available data.
