FoxFury, Pix4D, Sundance Media Group (SMG), and the Nevada Drone Center of Excellence came together during the InterDrone Conference, sharing techniques and technology used for capturing forensic scenes during night hours. This event will be repeated during the Commercial UAV Expo in Las Vegas on October 3, at the WestGate hotel. Register now for the Commercial UAV Expo CSI demonstration.
Sundance Media Group and the CSI data may also be viewed at Booth #5413 at the Global Security eXchange Security Conference and Expo, September 23-27 in Las Vegas, NV at the Las Vegas Convention Center. Register for the GSX show HERE.
“As you’d expect, the ratio of nighttime vs daytime crime is much higher,” said one investigator from a local law enforcement agency. “This sort of training and experience provides greater depth to our toolkit. We are grateful to have partners willing to research and share experiences that may benefit our agency.”
Using FoxFury Nomad Hi CRI, daylight-balanced lighting, to light the scene in an area of East Henderson where no power and no available light existed, the team used Hollywood makeup techniques, a bit of stage blood, and shell casings to re-create a genuine crime scene. The “crime scene” was kept pristine as nearly 100 attendees looked on.
The FoxFury Nomads, properly positioned, provide a no/low-shadow environment with accurate colors.
“Most LED lighting systems will generate a color-cast that may create problems in the post-capture investigation. Moreover, the lights do not require cabling that can trip up those on-scene, or create their own form of scene contamination. To place them, we merely pull down three legs, raise the pillar, and power up the lights. At half intensity, the lights provide approximately 12 hours of lighting,” says Douglas Spotted Eagle of Sundance Media Group. The FoxFury Nomads may be charged over a 12v connection in a patrol/support vehicle as well.
FoxFury Rugo’s are placed on the aircraft for additional lighting as well as for FAA compliance. The Rugo provides a constant flash indicator in addition to options for Flood, Flat, or Pinspot light distribution. The Rugo mounts for the Yuneec and DJI products offer a 360 swivel, allowing for light control in any direction. Users may choose from four intensities in addition to the flash/cycle option.
James Spear talked about the aircraft lighting, saying “We use the FoxFury Rugo’s for our scene and night lighting not only due to the many options for lighting focus, but also because of the interchangeable batteries. At full intensity, we enjoy about an hour of flight time, yet the lights will operate for up to three hours at lower intensities.”
Ground Control Points were laid into place on the perimeter of the scene, taking care to ensure no one stepped into the scene. These are used as tie-points during the 2D and 3D assembly of the data, using Pix4Dmapper. The GCP’s for night capture are painted with Day-Glo paint colors for bright visibility and identification in the darkness of night. Similar techniques may be employed during thermal mapping projects (Pix4Dmapper on the desktop may be used for thermal mapping if the thermal camera properly embeds/captures meta-data). Shown here by Brady Reisch of the SMG team, the GCP’s are a highly-valued component to set scale constraints to the scene.
The area was flown with a drone equipped with a camera capturing GPS location, capturing a reduced area for purposes of avoiding flight over persons, and for expediency during the demonstration.
The pilot, wearing a Brother AiRScouter HUD, is able to simultaneously observe the aircraft and telemetry. Attendees of the event had opportunity to wear the HUD and appreciate the value of a constant display that enables pilots to observe the aircraft, telemetry, and video data, all at once. Jennifer Pidgen of SMG commented, “We have equipped each of our pilots with the AiRScouter system not only for these scenarios, but more importantly for those times where we’re inspecting critical detail and looking away from the aircraft may increase risk. The AirScouter enables our pilots to observe the aircraft flying closely to objects while providing a constant stream of information to the pilot.”
The sUAS captured nearly 100 photos used to create the overall model/map of the scene. Normally, the scene would encompass the entire area in the event that there may be more clues hidden in the brush or sandy areas surrounding the site. Thermal may also be used to search for other bodies, or persons involved in the crew.
“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, as shown in the Pix4D booth at InterDrone.”
The point cloud of the scene is shared online here. Hold CTRL+SHIFT to rotate the scene in 3 dimensions.
Once the scene is captured, the rectified scene may be viewed internally or via secured online site by CSA, or Crime Scene Analysts, allowing measurements to be verified, retaken, or examined from a multitude of angles.
The Sundance Media Group team will be demonstrating this experience at the Commercial UAV Expo in Las Vegas on October 3. Location TBA, near the WestGate hotel (walking distance). REGISTER HERE. It is recommended that attendees register early. The last event ran out of space/slots within three days.
Douglas Spotted Eagle addresses a crowd of nearly 100 attendees at the CSI demo.
Sam Pepple of Pix4D addresses the crowd, describing how Pix4D will be used to capture the scene, the importance and value of GCP, and why these models are valuable to crime scene investigators.
An investigator briefs the crowd on how UAS are changing the face of scene capture, and details how a scene is approached, observed, captured, and processed.
We captured the scene using multiple drones. Brady Reisch captured video of the event; we’ll soon have that available for viewing.
The SMG AVOC was the hub of activity prior to the night flight. Pizza and drinks provided by FoxFury and Pix4D.
The FoxFury Rugo lights are a key component to SMG night flight. They may be mounted to nearly any sUAS platform including Yuneec H520, Hplus, DJI Phantom, Inspire 1, Inspire 2, Matrice 200 series, AEE Mach 4, and many others.
