Electronic Scoring System : Data Processing & Presentation (English)
Abstract [sv]

Denna rapport beskriver ett projekt med målet att utveckla ett elektroniskt skyttesystem utifrån mindre kostsamma standardkomponenter. Det utvecklade systemet avses inneha funktionalitet som är jämförbar med befintliga sådana system. En utredning av det utvecklade systemets precision ämnas utföras, och om precisionen visar sig vara undermålig behöver en utredning ge förslag på ytterligare hårdvara som krävs för att nå en högre sådan. Projektet resulterade i ett delvis sammankopplat, fungerande system. Systemet består av fysiska komponenter, en databas och en visningsklientsapplikation som bearbetar och presenterar data. Systemets fysiska komponenter innefattar fyra mikrofoner och en Raspberry Pi 2-enhet. Mikrofonerna registrerar ljudankomster och signalerar dessa till Raspberry-enheten, som sparar data i databasen. Denna data hämtas, bearbetas och visualiseras av visningsklienten.Systemet saknar i nuläget en fysisk träffyta, och precisionsbrister hos dess fysiska komponenter resulterar i opålitliga resultat, då mätvärden är okonsekventa utifrån upprepade träffar på en specifik position.

Abstract [en]

This report describes a project with the goal of developing an electronic scoring system from less costly standard components. The developed system means to have comparable functionality to existing such systems. An analysis of the developed system's precision is intended to be performed, and if the precision is found to be substandard an investigation needs suggest further hardware necessary for reaching a higher one.The project resulted in a partially connected, functioning system. The system consists of physical components, a database and a visual client application that processes and presents data. The system's physical components comprise four microphones and a Raspberry Pi 2 unit. The microphones register sound arrivals and signal these to the Raspberry unit, which saves data in the database. This data is retrieved, processed and presented by the visual client.The system currently lacks a physical target surface, and precision flaws in the system's physical components result in unreliable results, since readings are inconsistent from repeated hits at a specific position.
