Claims (12)
1. Lysdetektionssystem, kendetegnet ved, at lysdetektionssystemet omfatter: et kamera (220) med rullende lukker, hvilket kamera er indrettet til at opnå mindst ét billede af en scene, som belyses af et belysnings system (110), der omfatter i det mindste en første lyskilde (111, 112, 113), som yder et lysbidrag, der omfatter en første indlejret kode (ID#1, ID#2, ID#3), som udsendes som en tidssekvens af modulationer i en karakteristik af det udsendte lys, hvor nævnte billede omfatter en matrix af pixels, hver pixel repræsenterer en intensitet af en samlet lysydelse af nævnte belysningssystem på en forskellig fysisk position i scenen, og hvor nævnte billede opnås som en flerhed af tidsforskudte linjeforekomster, som hver især omfatter en linje af nævnte pixels, der samples ved en forskellig forekomst af nævnte tids sekvens af modulationer af den første indlejrede kode, idet linjerne eksponeres tidsmæssigt linje for linje på forskellige tidsforekomster med en tidsforsinkelse mellem tilstødende linjer for således at give anledning til et rumligt modulationsmønster svarende til tids sekvensen af modulationer, og en behandlingsenhed (230), som er indrettet til at bestemme nævnte første indlejrede kode ud fra det rumlige modulationsmønster.
2. Lysdetektionssystem ifølge krav 1, hvor nævnte behandlingsenhed er konfigureret til bestemmelse af den første indlejrede kode baseret på en kombination af pixelværdier langs hver linjeforekomst.
3. Lysdetektionssystem ifølge krav 1 eller 2, hvor nævnte kombination af pixelværdier langs linjeforekomster er begrænset til mindst ét fomdbestemt underområde af nævnte opnåede billede.
4. Lysdetektionssystem ifølge krav 3, hvor et udvalg af nævnte forudbestemte underområde udføres ved at sammenvikle nævnte billede med et filter med en filterkerne, hvilken filterkeme er indrettet til at matche et forventet rumligt modulationsmønster tilknyttet nævnte første indlejrede kode.
5. Lysdetektionssystem ifølge krav 1, hvor hver af nævnte linjer udgør en række af pixleme af nævnte matrix.
6. Lysdetektionssystem ifølge krav 5, hvor nævnte eksponering ved forskellige tidsforekomster af pixelrækker forekommer i en rumligt monoton rækkefølge.
7. Lysdetektionssystem ifølge et hvilket som helst af de foregående krav, som yderligere er indrettet til at detektere og analysere bidrag fra en flerhed af lyskilder i det opnåede billede, hvor hvert lysbidrag fra en respektiv lyskilde omfatter en indlejret unik kode, der udsendes som tidssekvenser af modulationer i en karakteristik af det udsendte lys.
8. Lysdetektionssystem ifølge et hvilket som helst af de foregående krav, som yderligere omfatter et optisk system til tilvejebringelse af defokusering af nævnte opnåede billede.
9. Lysdetektionssystem ifølge krav 8, når dette er afhængigt af krav 7, hvor nævnte optiske system omfatter et åbningsmaskeelement til tilvejebringelse af et mønster i nævnte defokuserede opnåede billede.
10. Lysdetektionssystem ifølge krav 9, hvor en rumlig form af nævnte åbningsmaskeelement vælges med henblik på rumligt at adskille lysbidrag, som stammer fra forskellige lyskilder.
11. Lysdetektionssystem ifølge et hvilket som helst af de foregående krav, hvor nævnte indlejrede kode transmitteres på gentagen måde, idet den er én af en kontinuerlig repetitiv datastrøm, en pakket datastrøm med pakker med regelmæssige mellemrum, og en pakket datastrøm med pakker med uregelmæssige mellemrum.
12. Lysdetektionssystem ifølge et hvilket som helst af de foregående krav, hvor karakteristikken af det udsendte lys er én af en intensitetsmodulation og en farvemodulation.
