A concept of a vision system for position determinationusing spatial-time-frequency analysis

This paper presents the concept of a vision system designed to determine the positionof a camera within a given coordinate system. The system focuses on identifying pulsatinglight markers in images recorded by the camera. These markers are characterized by spe-cific colors, pulsation frequencies and known locations. Detection is achieved using a spatial-time-frequency processing method developed by the authors. The identified markers serve asinput data for a mathematical model that determines the camera’s position within the refer-ence system. The article discusses the theoretical foundations of the proposed system design.The system was subjected to testing to verify its operational accuracy and precision in positiondetermination. The results of these tests are presented. The article concludes with a summaryof the work and a discussion of the system’s further development and practical applications.Keywords:image processing; spectrum analysis; light markers; localization.
