To document vital evidence after an accident or at the scene of a crime, first responders need to act fast, even in challenging conditions.

With drone technology and Pix4D, a scene can be documented in as little as 20 minutes in the right conditions – but challenging conditions can slow things down, potentially allowing vital information to be lost.

Lighting is one of the biggest challenges facing public safety personnel. Low or no light can mean blurry or too-dark images which may require color correcting or even lose vital data. Adding light with flashlights or standard floodlights can cast harsh shadows.

A recent demonstration during the InterDrone Conference offers an alternative.

  

 

Two systems were used to create a no/low shadow environment. FoxFury Nomad Hi CRI, daylight-balanced lighting, a portable ground lighting system, and FoxFury Rugo which was mounted on the Yuneec H520 to produce daylight-like light even on the darkest nights. This system can also be mounted in drones like DJI Phantom, Inspire 1, Inspire 2, Matrice 200 series.

To set the scene, teams from FoxFury, Pix4D, Sundance Media Group (SMG), and the Nevada Drone Center of Excellence used actors, fake blood and bullet casings to create a realistic incident. The location did not have any lighting (or for that matter, any electricity to power floodlights).

 

 

“The images were then taken into the Sundance Media Group AVOC computers, where we assembled them as a low-resolution 2D file to verify all areas of the scene were adequately captured,” said Sam Pepple, of Pix4D. “Once verification and confirmation are complete, the scene may be released to the rest of the CSI team for standard investigation. Following the low-resolution verification, a high-resolution image was processed and evaluated by the team.”

Said Sam Pepple, “Pix4D is revolutionizing yet another domain, this time public safety.”

“Douglas Spotted Eagle and the whole Sundance Media Group really understand the issues facing public safety officials, and they work hand in glove to meet these needs. These great solutions seem effortless, but they come from their deep subject matter expertise and by having great relationships with all the best-in-class across the industries: from lighting, to drones, to photogrammetry with Pix4D.”
