Physical security increasingly involves sophisticated, real-time visual tracking of a person's location inside a given environment, often in conjunction with biometrics and other security-related technologies. However, demanding real-world conditions like crowded rooms, changes in lighting and physical obstructions have proved incredibly challenging for 2D computer vision technology.
In contrast, 3D imaging technology is not affected by constant changes in lighting and apparent color, and thus allows tracking accuracy to be maintained in dynamically lit environments. In addition, person tracking with a 3D stereo camera can provide the location and movement of each individual very precisely, even in a very crowded environment. A successful person tracking system, must not only perform visual analysis robustly, but also be small, cheap and consume relatively little power.
The TYZX Embedded 3D Vision systems are perfectly suited to provide the low power, small footprint, and low cost points required by these types of volume applications. Several security-focused organizations, including the U. Visual uninstrumented tracking of natural hand gestures and movement provides new opportunities for interactive control including: video gaming, location based entertainment, and interactive displays.

Infrared stereo calibration for unmanned ground vehicle navigation. The problem of calibrating two color cameras as a stereo pair has been heavily researched and many off-the-shelf software packages, such as Robot Operating System and OpenCV, include calibration routines that work in most cases.
However, the problem of calibrating two infrared IR cameras for the purposes of sensor fusion and point could generation is relatively new and many challenges exist.
We present a comparison of color camera and IR camera stereo calibration using data from an unmanned ground vehicle. There are two main challenges in IR stereo calibration; the calibration board material, design, etc. We present our analysis of these challenges along with our IR stereo calibration methodology.
Finally, we present our results both visually and analytically with computed reprojection errors. Track fitting in the opal vertex detector with stereo wires.

Federal Laboratory Consortium — The TLV is designed to apply forces close to the strength limits of the rails and other track structure components, such as ties, rail fasteners, and ballast, while Comparison of different "along the track " high resolution satellite stereo -pair for DSM extraction.
The possibility to create DEM from stereo pairs is based on the Pythagoras theorem and on the principles of photogrammetry that are applied to aerial photographs stereo pairs for the last seventy years. The application of these principles to digital satellite stereo data was inherent in the first satellite missions. Both of them acquire stereopairs along the track with a 2,5m spatial resolution covering areas of 30X30km.
In this study we compare two different satellite stereo -pair collected along the track for DSM creation. The area of study is situated in Chalkidiki Peninsula, Greece. After a first control for random or systematic errors a statistical analysis was done.
Points of certified elevation have been used to estimate the accuracy of these two DSMs. The elevation difference between the different DEMs was calculated. The detection and pose estimation of vehicles plays an important role for automated and autonomous moving objects e. We tackle that problem on the basis of street level stereo images, obtained from a moving vehicle.
Processing every stereo pair individually, our approach is divided into two subsequent steps: the vehicle detection and the modelling step. For the detection, we make use of the 3D stereo information and incorporate geometric assumptions on vehicle inherent properties in a firstly applied generic 3D object detection.
By fitting an object specific vehicle model into the vehicle detections, we are able to reconstruct the vehicles in 3D and to derive pose estimations as well as shape parameters for each vehicle. To deal with the intra-class variability of vehicleswe make use of a deformable 3D active shape model learned from 3D CAD vehicle data in our model fitting approach.
While we achieve encouraging values up to The evaluation is done by using the object detection and orientation estimation benchmark of the KITTI dataset Geiger et al.

Zippo dating marks. Date codes were originally put on the bottom of Zippo lighters to track the types of repairs that were being performed and I doubt that anybody at the time would have realised how that move would make these lighters so collectable.
Slim lighters were first introduced in 1956 with no markings, the markings were introduced in 1957 and overlapped into 1958. From 1966 the date codes for slim lighters has been the same as the regular size lighters. The codes below will help you to date your Zippo but other factors need to be taken into account.
