TRACKEYE & TEMA typical applications:

• Store separation: Verifying the simulated behavior of a store during flight test is a technically complex issue. Using TRACKEYE Stores Release 6DoF makes the task easy, even with only one camera, to analyze and obtain time stamped complete 6DoF data. The 6D (six degrees of freedom, 6DoF) optional add-on package for TRACKEYE provides functionality for computing the position (x, y, z) as well as the attitude (roll, pitch, yaw) of one or more rigid objects, which are observed by at least one camera mounted on wing tips or under the fuselage of an aircraft.

• Blast and Fragments analyses: During an arena test, the ARENA application collects inputs from one or several cameras monitoring a single or multiple screens which are pierced by shrapnel and particles. The location and timing of each piercing is recorded. Then statistics can be performed on number and shape of fragments, mean velocity versus azimuth or elevation angles. The complete repartition of the fragments in space can be displayed in 3D diagrams.

• Biomechanics analyses: In order to gain a greater understanding of performance in athletic events through modeling, simulation, and measurement, TEMA can be combined with a set of cameras to get a powerful and highly cost-effective biomechanical 3D measurement system, suitable for applications like golf swings or cycling performances improvement.

• Automotive crash labs applications: TEMA Automotive is the market-leading software suite for advanced Motion Analysis tests in the automotive industry. Thanks to its high accuracy, modular structure, calculation speed and intuitive user interface, TEMA is used by professionals across the globe in a wide range of Automotive Testing applications from airbag deployment analysis to behavior of dummies during crash tests as well as car deformations after impact. Operators are able to import image sequences and automatically track any given object throughout the sequence via a set of dedicated tracking algorithms. The result is presented in predefined formats such as tables and graphs showing quantifiable values for example position, speed and acceleration over time.

• Digital Image Correlation: When designing any mechanical system, knowledge of the properties of the used material is crucial. To gain such knowledge, accurate measurements of the material’s strain and deformation can be done. Digital Image Correlation (DIC) is an optical, non-contact, full-field-deformation analysis method, based on monochromatic digital images, which can determine strain and deformation of an object under load.

With TEMA DIC it is possible to accurately measure full strain fields and extensometer strains over a complete surface. This allows for non-contact measurements of strain, allowing analysis of the material properties, without affecting the result through contact. TEMA DIC comes as a tracker option to TEMA.

TEMA DIC System is a complete system solution including all the required hardware and software for non-contact optical analysis for surface strain and displacement. The system is designed for easy set-up and use. The components are delivered in appropriate transport cases and are thus highly portable. Camera and lightening are mounted on a stable and flexible 3-axis geared head, attached to a perpendicular bar allowing for rough and fine position tuning. Calibration is done to correct for both lens distortion and angled motion plane deviation between the camera and the specimen. This feature is unique to TEMA DIC and enables the 2,5D tracking capability.

TEMA DIC and TEMA DIC System comes in a 2D and a Stereo version. The Stereo version has 2 cameras and is capable of measuring surface strain & deformation.


Tracking Mounts

• Tracking Mounts: Many military test ranges worldwide deal with the measuring of position and attitude of moving objects using dedicated tracking mounts which can follow objects at large distances. The main feature to be measured for these studies is the 3D position of the object at different times. Using the 3D position data all kinds of analysis can be performed, e.g. calculating the distance between a missile and a target. Several tracking mounts positioned at different locations can be used in concert. Recording the direction to the object from different angles results in high accuracy 3D positions using TRACKEYE. The program tracks objects in images automatically, handles the positions of the tracking mounts, integrate different calibrations and corresponding corrections, transforms coordinate systems and calculates the position for all objects.



• Drop Testing: In combination with drop test machines, TEMA software offers complete 2D or 3D analysis of the drop of objects before and after impact on the ground. Accurate results can be displayed like the shockwave propagating on the surface of the device at impact. Customized coordinate systems can be used to display relative movements of the different parts of the device during the fall.

• 6Dof analysis: The position of a rigid body can be described with six parameters referred as 6 Degrees of Freedom: three positions coordinates (x, y and z), which gives the position of a specific point on the body, and three attitude angles (roll, pitch and yaw), which gives the orientation in space. The modularity of the software gives the user an almost unlimited number of application areas from rifle analysis during burst shots through analysis of dummy head movement during crash tests in automotive industry.

• Medical Analyses: TEMA can be used also for a wide range of Medical applications. Using correlation or outline algorithms, the behavior of living parts can be analyzed. For instance frequency diagrams of a beating heart or opening and closing of valves can be easily computed. Cells displacements or volumes and shapes of organs can be calculated and displayed in 2D and 3D Diagrams.

• Shock and Vibration analysis: From big displacements to small ones after impact, the full 3D behavior of objects submitted to shocks can be analyzed using TEMA. Remaining vibrations of drills or bumpers as well as resonances of parts induced by impacts can be displayed in frequency diagrams using a range of sub-pixel accuracy algorithms.

• CAMERA CONTROL: TEMA Camera Control is the optimal tool for controlling multiple high speed cameras of different models and different brands. TEMA Camera Control can control all the major high-speed cameras on the market, all at the same time and from a single interface with no limitation of the number of high speed cameras.

• POM: Projectile Orientation Measurement (POM) is a test platform based on the TRACKEYE Motion Analysis technology.  Using calibrated and oriented high-speed cameras and flash units, mounted at defined angles – POM allows for repeated testing and measurement of impact angle(s) and 3D position(s) of a bullet approaching a target.

• STATIC 3D: The Static 3D module is used to survey static objects in order to build target models from images of the object. Markers are used to increase the accuracy of the calculation. The set-up procedure involves assigning tracking algorithms to markers in the images. If the markers have certain symmetries (e.g. quad markers or circles), the algorithms will automatically lock on to the center of each marker with sub pixel accuracy. The resulting 3D coordinate data can be exported to file and then later imported into TRACKEYE or TEMA under different formats.

• TERX 3D: TERX 3D enables a test operator to analyze plasma droplets and streams in up to three dimensions.  Applications areas include the development and testing of shaped charge explosives for military, construction & demolition purposes. During a TERX 3D test, a series of X-ray flashes are used to generate shadows of individual plasma elements, which are then captured on film and analyzed. The image files, together with the 3D coordinates of the cross hairs and the X-ray sources, are the base for the analysis together with the contour and position of each droplet generated during the tracking process.

• MIRROR TRACKERS: Mirror Trackers, such as the Trajectory Tracker which provides images of ballistic and non-ballistic projectiles using a high speed camera in combination with a rotating mirror to follow the flight path. By combining the image sequences from the cameras, with the exact angle of the mirror it is possible to visualize the flight path and analyze the motion of the projectile; typically 2D/3D position, attitude (pitch and yaw), roll rate, velocity and acceleration. When two Trajectory Trackers or Flight Followers are used data can be calculated in up to six dimensions.

• SDK: The SDK, the Software Developers Kit, is the advanced capability to program TRACKEYE functions in C++ language. The TRACKEYE Software has an open architecture that will allow a user to add new functionality to the system. The SDK provides a programming interface. The SDK allows you to build your own functions and add icons to the supplied list in the standard TRACKEYE program. It is also possible to add new tracking algorithms within the supplied tracking function. With the SDK a TRACKEYE user can concentrate on key functions in his application, utilizing the framework for handling and working with image sequences that already exists.
