3d face recognition software has become much more advanced, and it has gotten to the point that biometrics face recognition software is incredibly accurate and easily able to determine the difference between very similar facial structures.
Thanks to the latest video biometric 3d face technology, biometrics security devices have now become much more difficult to crack or penetrate, and thus they have now become much more secure than older technologies.
3d facial recognition devices now provides the very latest enhanced security for those who can afford it, though these 3d recognition devices tend to be much more expensive than the basic biometric scanning devices.
The face recognition technology is integrated with a biometric scanner device and computer software 3d databases to ensure its efficiency.
Step 1: The user places his head in front of the 3d face recognition scanner. The head should be placed directly in front of the scanner in order to ensure that it can capture the features as easily and accurately as possible.
Step 2: The facial recognition scanner projects a structured pattern of light onto the face of the person trying to gain access. The light is invisible, but it maps the persons features by being distorted by the uneven surface of the face.
Step 3: Once the light pattern recognition passes, the pattern captured by the light is input into the reconstruction software. The software reconstructs the captured image of light into a 3d image. The 3d mesh used to reconstruct the face is created using simple triangulation, and a copy is created. All of the features of the face are captured down to the millimeter, as the light that captures the image is incredibly accurate.
Step 4: The reconstructed image is then sent on to the matching part of the biometric software, and images are pulled from the database. These are compared with the reconstructed 3d image of the person’s face, and the various features are matched as precisely as possible.
All of the different parts of the facial structure are taken into account, including the skull shape, shape of the jaw line, chin shape, eye shape, cheek bones, and nose structure. The image is matched carefully against the various templates already stored in the database until it finds one that it matches.
Step 5: The matching recognition engine used to compare the faces determines if the facial structure matches the one of the templates in the database sufficiently to be allowed authorization. If it does, the scanner displays the "Access Granted" message or its equivalent, and access is granted. If there is no facial match, the user is able to try again or try entering a master key code that will override the scanner.
In reality, all five recognition steps happen within a matter of seconds. The light captures the structure of the face in a couple of seconds, and the computer matches it quickly with all of the authorized 3D templates in the system data base.
The 3D face recognition software is able to match it within seconds, and access is granted incredibly quickly. When it comes down to it, it is one of the most convenient systems while still being one of the most secure. Seeing as the entire skull shape and structure is matched, there is little chance that even someone who looks nearly identical would be able to gain access.
If you are looking to secure your home or business with biometrics security devices, it is very important that you know what will suit your needs.
