Mayelana nalolu hlelo lokusebenza
IHydroColor iwuhlelo lwekhwalithi yamanzi olusebenzisa ikhamera yedijithali ye-smartphone ukuze inqume ukuvela kwemizimba yamanzi yemvelo. Isebenzisa lolu lwazi, i-HydroColor ingalinganisa ukuguquguquka kwamanzi (0-80 NTU), ukugxila kwe-suspended particulate matter (SPM) (g/m^3) kanye ne-backscattering coefficient ngokubomvu (1/m). KUBALULEKILE: I-HydroColor idinga ukusetshenziswa kwekhadi elimpunga elingu-18% labathwebuli njengereferensi. Amakhadi ampunga atholakala kabanzi ezitolo zezithombe naku-inthanethi. Vakashela iwebhusayithi esekelayo ukuze uthole ulwazi olwengeziwe ngamakhadi ampunga.
IHydroColor inesixhumi esibonakalayo esisebenziseka kalula esiqondisa abasebenzisi ekuqoqweni kwezithombe ezintathu: isithombe sekhadi elimpunga, isithombe sesibhakabhaka, nesithombe samanzi. Ukuqinisekisa imiphumela ehamba phambili, i-HydroColor ithinta i-GPS yedivayisi, i-gyroscope, nekhampasi ukuze isize abasebenzisi eqoqweni lalezi zithombe. Ngemva kokuqoqwa kwezithombe zingahlaziywa ngokushesha. Ekuhlaziyeni izithombe, i-HydroColor ibala ukubukeka komzimba wamanzi eziteshini zombala ze-RGB zekhamera. Ibese isebenzisa amanani okubonisa ukuze inqume ukuxubeka kwamanzi ku-NTU (amayunithi e-nephelometric turbidity).
Idatha igcinwa khona manjalo futhi ingafinyelelwa futhi nge-HydroColor noma ilandelwe kukhompuyutha kufolda yedatha ye-HydroColor. Ifayela lombhalo liqukethe ulwazi olwengeziwe mayelana nesilinganiso okuhlanganisa: i-latitude, i-longitude, idethi, isikhathi, i-sun zenith, i-sun azimuth, isihloko sefoni, ukuphakama kwefoni, amanani okuchayeka, ukubonakaliswa kwe-RGB, kanye ne-turbidity.
Isebenza kanjani:
I-HydroColor isebenzisa ikhamera njengenzwa yokukhanya elula (i-photometer). Ubukhulu bokukhanya obuhlobene bungalinganiswa ngokwenza amanani ephikseli yekhamera abejwayelekile ngokuchayeka. Ngakho-ke, iziteshi ezintathu ezinemibala yekhamera (RGB: Red, Green, Blue) zinikeza isilinganiso sokukhanya kokukhanya ezifundeni ezintathu ze-spectrum ebonakalayo.
Ubukhulu bokukhanya obukalwe emfanekisweni wamanzi bulungiswa ukuze kubonakale isibhakabhaka ngaphandle (kusetshenziswa isithombe sesibhakabhaka). Isithombe samanzi esilungisiwe sinikeza ukushuba kanye nombala wokukhanya ophuma emanzini. Lokhu kwenziwa ngokwejwayelekile ukukhanya kwe-ambient kusetshenziswa isithombe sekhadi elimpunga. Umkhiqizo wokugcina uyisilinganiso esicishe sibe sokukhanya esizimele sokubonakala kwamanzi, okwaziwa ngokuthi i-remote sensing reflectance. Ku-oceanography, amasathelayithi asetshenziselwa ukubala umkhiqizo ofanayo (i-remote sensince reflectance) emkhathini.
Ukubonakaliswa kuhlobene ngokuqondile nenani kanye nohlobo lwezinhlayiya ezimisiwe emanzini. Ukwanda kwe-turbidly (okungukuthi ama-sediments amisiwe) kuzodala ukuhlakazeka okukhulu kokukhanya futhi kukhulise ukubukeka kwamanzi kukonke. Izinhlayiya eziqukethe umbala, njenge-phytoplankton (ulwelwe), zizomunca ukukhanya ezindaweni ezithile ze-spectrum ebonakalayo. Ngakho, i-pigment equkethe izinhlayiya ingatholwa ngokuqhathanisa ukubonakaliswa okuhlobene eziteshini ze-RGB.
Indlela esetshenziswa i-HydroColor ukulinganisa ukubukeka kwayo ishicilelwe kujenali ebuyekezwe ngontanga Izinzwa futhi itholakala mahhala ku-inthanethi (qaphela: I-HydroColor ibuyekeziwe ukuze isebenzise idatha ye-RAW evela kunzwa yekhamera kusukela kulokhu kushicilelwa):
