FBI to Use Cadre's TopMatch-GS 3D SystemCadre Forensics is a provider of 3D Surface Topography scanning hardware and software to the Federal Bureau of Investigation's Firearms/Toolmarks Unit. In May 2017, after completing an internal validation study, the Quantico, Virginia based FBI-FTU went live with the use of the TopMatch system. Announcement
Version 3 Scanner Available Fall 2017!Orders for the TopMatch-GS 3D Version 3 system are now being taken. The new scanner extends V2 with a new imaging subsystem and an automated scanning tray for up to 15 cartridge cases. Load the tray and let the system collect the scans! While the V3 system is still under wraps, you can learn more about the V2 system below. Jump the line by requesting more information. Check back as more details are released! Contact Us
Version 2 ScannerThe TopMatch-GS 3D Version 2 system is now available to government and private crime labs. The system includes scan acquisition hardware, desktop workstation, high resolution display, imaging and analysis software, and database search. A stand-alone Virtual Microscopy Workstation is also available. Hardware Demo Video Contact Us for a Quote Scaner Information Sheet Virtual Microscopy Workstation
The TopMatch Advantage
At the core of the TopMatch analysis and comparison system are a series of custom Computer Vision and Machine Learning algorithms. Computer Vision is the sub-discipline of Computer Science focused on understanding 2D and 3D image data. Machine Learning is the Computer Science sub-discipline focused on model building, statistics, inference, and decision making.
A trained TopMatch operator can typically scan over 30 casings per hour, approximately five times faster than other 3D technologies. This high throughput saves examiner time and reduces backlog. It allows a single examiner to enter multiple pieces of evidence and test-fires thereby increasing the likelihood of identifying a true positive match.
The TopMatch system is approximately the same cost as a forensic comparison microscope. A yearly maintenance package keeps your software updated, covers repairs, and provides access to consumables.
The TopMatch-GS 3D system was developed in close collaboration with Todd Weller (Criminalist, Oakland PD) and input from city, state, and federal forensics labs. These close relationships have guided hardware and software design improvements.
TopMatch organizes Evidence and Test-Fires into laboratory case files or Incidents. TopMatch implements a number of comparison tools including both computer guided analysis and match score as well as human guided virutal microscopy where casings can be compared using a virtual lightbox setup.
TopMatch is being developed to support Blind Verification efforts within a crime lab. After a human examiner comes to a conclusion regarding match vs non-match, the two compared casings can be brought to TopMatch for independent analysis. TopMatch will compare the two casings and render its opinion in the form of a numerical confidence score.
The TopMatch system stores your scans on your local machine. This makes their access extremely fast. Make backups, copy scans to thumb drives, send them by email, or exchange them over the soon-to-be announced CadreNexus. TopMatch fully supports the X3P file format. It's your data!
X3P File Format Standard.
Cadre and TopMatch fully support the now industry-standard X3P file format for the exchange of scan topographies. Supported by the OpenFMC group, any X3P enabled 3D scanner can export data to any X3P supporting analysis software. Any 3D scanner that supports X3P can be used with our software (e.g. many confocal microscopes). When comparing 3D scanners ask if they support X3P. Learn More About X3P
