Event-Data

Event Data Recorder

The vehicles crash data is an essential piece of evidence to be collected and evaluated as part of the vehicle crash investigation. The crash data can provide a better understanding of critical data elements associated with the crash. The parameters that could possibly be displayed from the vehicle crash data includes vehicle speeds, seat belt status, steering input, and delta-v, this data displayed can ultimately determine the state of the vehicle before the collision. Our certified engineers have the capability of acquiring this data and interpenetrating it in an easily readable format.

Evidence Storage

With our facilities inspection bays, inspections on cars, trucks, tractors, RV’s and mechanical machinery can be efficiently conducted under our shaded inspection bays. Our facility also includes a vehicle lift under shaded and covered area allowing for a detailed underbody inspection of the subject vehicle. We tailor our investigations to meet our customers’ needs and address their most significant concerns.

Event-Data

Drone Aerial

With the use of our drone and FAA certified pilots, unique and vivid photographs/video can be captured in 4k. Applying unmanned aerial systems technology we can use photographs captured by the drone to create realistic 3-D survey/model of the project. With the help of a three-axis 4k camera, there is nothing the drone cannot capture effortlessly to make your project stand out.

Event-Data

Night Time Analysis

Night time & Visibility analysis is done to understand exactly what the person can visibly see at night given the same circumstances. Using the same environmental and lighting conditions, a recreation of the scenario is generated to view the actual visibility of the environment.
With the use of high-tech equipment, a true lighting visibility method can be used to show closely as to what the human eye can see.

Video Analysis

With the breakdown of any surveillance video into I, P and B frames, data can be taken, and analysis can be extrapolated from the views. Correcting the fisheye effect of surveillance cameras allows JEA to do a more accurate placement of vehicle/people placement, speed, time, color correction and distance can be determined from the review of the video. Breakdown of the video allows for a more clear view of what had occurred, compared to what the camera had seen.

Exemplar Models

JEA conducts many exemplar inspections and has a vast database of vehicles that have been 3-D generated. 3-D models can be produced in many formats, with the model; photos and measurements will also be provided. Anything from heavy-duty vehicles to passenger vehicles can be measured and modeled in a 3-D format, allowing you to compare a damaged vehicle.
