AirCSI is a prototype drone system that scans crime scenes from above, identify possible pieces of evidence, and then collect more detailed images and data of such items of interest. Leading the development of the system is Pompílio Araújo, a researcher at the Intelligent Vision Research Lab at Federal University of Bahia who often assists the Federal Police of Brazil in crime scene investigation. From IEEE Spectrum:
“…AirCSI provides a sketch with the localization of the evidences, as well as a detailed crime scene imagery,” says Araújo. His team used simulation software to test this newer version of AirCSI, and found that using multiple angles to detect evidence is up to 18 percent more effective than using only one angle…
While the researchers have yet to test the new, multi-angle approach beyond simulations, they expect to try it out in a real environment by the end of this year or early next year…
He also plans on developing a way to completely reconstruct crime scenes using the drone footage, creating a virtual environment that investigators can explore indefinitely—or at least until the crime is solved.
