Abstract(in English) | In order to measure movement of objects (for example, players) at a high spatial and temporal resolution in sports of a large field, a measurement system using a laser beam scanner is being developed. In this system, a vertical slit beam is scanned at 360Hz in the measurement field. The beam is reflected by the surface of moving objects, on which high retro reflective sheets are stuck. The returning beam is detected by a linear position sensing device(PSD). Horizontal position is calculated by determining the exact time of reflection, and vertical position is determined by a position output of the PSD, both of which are performed in real time. To discriminate multiple targets in the field from optical background noise within 1 measurement cycle time(2778[μs], a feature extraction method has been employed. The algorithm has been proved to be able to detect up to 5 moving objects in real time. |
