Paper Abstract

In the 2009 sessions a laser based imaging system for geometrical measurement of projectile trajectories was presented. This system has been extended to be able to gather 3D data. Therefore the mathematical baseline is given and measurement errors are estimated. An approach is shown how the direction of a trajectories' origin could be ascertained using the current system. A simulation software has been developed to emulate test firings and measurements under certain assumptions and different configurations. As a first step, simulations on the sensor grid error were carried out. Accuracies for determination of the direction of a trajectories' origin dependent on the sensor grid errors were computed for a sample setup and will presented here.
