Part One: What’s In Our (Data Collection) Toolbox?



Jon W. Adams, Director of Architectural and Heritage Services ::::
At DJS, we utilize a number of different tools to collect important data. Whether we are working on a forensic case, capturing as-built measurements for AEC documentation, or digitally preserving important historic landmarks, it is always important to have the right tool for the job.

DSLR cameras/video recording systems

Although DSLR (digital single-lens reflex) cameras and video recording systems are common items utilized by millions of consumers in their everyday lives, they are still essential tools in every DJS case/project.
Video recording systems are utilized to analyze signal timing patterns at intersections of interest, and also to provide a visual record of inspection procedures.
DSLR cameras are used by DJS technicians to capture photographs during accident site investigations/vehicle inspections, providing additional context for measurement data that is captured, and also supplementing details relating to conditions present at the time of the inspection.
DSLR cameras are also being used to capture high-resolution still images, which can serve as a foundation for photogrammetric reconstructions when necessary/beneficial.

UAS (Unmanned Aerial System)/Drones

Much like the DSLR/video recording systems mentioned above, UASs utilized by DJS also capture high-resolution still images, and high-definition video footage. The differentiation is that with UASs, the optics are attached to quadcopter aerial platforms.
UAS technology continues to evolve rapidly, providing intelligent, safe aerial platforms from which previously unattainable still images and videos can be captured. These new perspectives are allowing DJS engineers the ability to gain additional insight into the larger context of accident scenes, analyze details on critical upper surfaces of taller vehicles, and produce photogrammetric reconstruction data to accurately document tall structures and rooftops in the AEC realm.
