Motion Capture System, Neural Networks, Dynamical Systems

The aim of this article is to outline possibilities of sound and its physical properties during shooting of moving objects. Attention was devoted to the specific location of a fixed point in the space and time. We proposed appropriate topology of the system that depends on the required accuracy, acoustic properties and selected sound technologies. Developed software, which processes a detected sound signal, is based on artificial neural networks. The neural network identifies a distance between an active transmitter and a receiver on the basis of sound pulses transmitted from transmitters in the defined domain. Consequently, another neural network uses obtained distances between transmitters and a receiver as its inputs to determine an actual position of the receiver in space. Developed software is implemented in C language.
