KUTHENI IKHAMERA IFUNA “Ulawulo longqamaniso”
Sonke siyazi ukuba ngexesha lokuhamba, i-drone iya kunika i-trigger-signal kwiilensi ezintlanu zekhamera ye-oblique. Iilensi ezintlanu ngokwethiyori kufuneka zivezwe kungqamaniso olupheleleyo, kwaye emva koko urekhode ulwazi lwePOS enye ngaxeshanye. Kodwa kwinkqubo yokusebenza yokwenyani, sifumene ukuba emva kokuba idrone ithumele isiginali yokuqalisa, iilensi ezintlanu azikwazanga ukuvezwa ngaxeshanye. Kwakutheni ukuze kwenzeke oku?
Emva kwendiza, siya kufumanisa ukuba umthamo opheleleyo weefoto eziqokelelwe ngamalensi ahlukeneyo ahluke ngokubanzi. Oku kungenxa yokuba xa usebenzisa i-algorithm yoxinzelelo olufanayo, ukuntsonkotha kweempawu zokuthungwa komhlaba kuchaphazela ubungakanani bedatha yeefoto, kwaye iya kuchaphazela ungqamaniso lokuvezwa kwekhamera.
Iimpawu ezahlukeneyo zokuthungwa
Okukhona kuntsonkothe ngakumbi ukuthungwa kweempawu, kokukhona kukhula inani ledatha ekufuneka ikhamera iyisombulule, icinezele, kwaye ibhale ngaphakathi., ixesha elininzi lithatha ukugqiba la manyathelo. Ukuba ixesha lokugcina lifikelela kwindawo ebalulekileyo, ikhamera ayikwazi ukuphendula kwisignali ye-shutter ngexesha, kunye ne-exposure-action lags.
Ukuba ixesha lekhefu phakathi kokuvezwa okubini lifutshane kunexesha elifunekayo ukuze ikhamera igqibezele umjikelo wefoto, ikhamera iya kuphoswa ziifoto ezithathwe ngenxa yokuba ayinakugqibezela ukuvezwa kwangexesha. Ke ngoko, ngexesha lokusebenza, itekhnoloji yokulawula ungqamaniso lwekhamera kufuneka isetyenziswe ukudibanisa isenzo sokuvezwa kwekhamera.
I-R&D yetekhnoloji yolawulo longqamaniso
Ngaphambili sifumene ukuba Emva kwe-AT kwisoftware, impazamo yendawo-yeelensi ezintlanu emoyeni ngamanye amaxesha inokuba nkulu kakhulu, kwaye umahluko wesikhundla phakathi kweekhamera unokufikelela kwi-60 ~ 100cm!
Nangona kunjalo, xa sivavanya emhlabeni, safumanisa ukuba ulungelelwaniso lwekhamera lusephezulu, kwaye impendulo ifike ngexesha elifanelekileyo. Abasebenzi be-R & D babhideke kakhulu, kutheni isimo sengqondo kunye nesikhundla sempazamo yesisombululo se-AT sikhulu kangaka?
Ukuze sifumane izizathu, ekuqaleni kokuphuhliswa kwe-DG4pros, songeze ixesha lokuphendula kwikhamera ye-DG4pros ukurekhoda umehluko wexesha phakathi kwe-drone trigger signal kunye nokuvezwa kwekhamera. Kwaye kuvavanywa kwezi meko zine zilandelayo.
Umboniso A: Umbala ofanayo kunye nokwakheka
Umboniso A: Umbala ofanayo kunye nokwakheka
Umboniso C: Umbala ofanayo, ukuthungwa okwahlukileyo
Umboniso D:imibala eyahlukeneyo kunye nokwenziwa
Itheyibhile yezibalo zeziphumo zovavanyo
Isiphelo:
Kwimiboniso enemibala etyebileyo, ixesha elifunekayo ukuze ikhamera yenze ukubala kweBayer kunye nokubhala ngaphakathi kuya kwanda; ngelixa imiboniso enemigca emininzi, ingcaciso ye-high-frequency yomfanekiso ininzi kakhulu, kwaye ixesha elifunekayo ukuze ikhamera icinezele nayo iya kwanda.
Ingabonwa ukuba i-frequency ye-sampling yekhamera iphantsi kwaye i-texture ilula, impendulo yekhamera ilungile ngexesha; kodwa xa i-frequency yesampulu yekhamera iphezulu kwaye ukuthungwa kuyinkimbinkimbi, ukwahlukana kwexesha lokuphendula kwekhamera kuya kwanda kakhulu. Kwaye njengoko ukuphindaphindwa kokuthatha imifanekiso kusanda ngakumbi, ikhamera iya kuthi ekugqibeleni iphoswe ziifoto ezithathwe.
Umgaqo wolawulo longqamaniso lwekhamera
Ekuphenduleni ezi ngxaki zingentla, i-Rainpoo yongeza inkqubo yokulawula impendulo kwikhamera ukwenzela ukuba kuphuculwe ukulungelelaniswa kweelensi ezintlanu.
Inkqubo inokulinganisa ixesha-umahluko "T" phakathi kwedrone ethumela isignali yokuqalisa kunye nexesha lokuvezwa kwelensi nganye. Ukuba umahluko wexesha "T" kwiilensi ezintlanu ungaphakathi koluhlu oluvumelekileyo, sicinga ukuba iilensi ezintlanu zisebenza ngaxeshanye. Ukuba ixabiso elithile lengxelo yeelensi ezintlanu likhulu kunexabiso eliqhelekileyo, iyunithi yokulawula iya kugqiba ukuba ikhamera inomahluko omkhulu wexesha, kwaye kwi-exposure elandelayo, i-lens iya kuhlawulwa ngokomahluko, kwaye ekugqibeleni. iilensi ezintlanu ziya kuvezwa ngaxeshanye kwaye umahluko wexesha uya kuhlala ungaphakathi kuluhlu olusemgangathweni.
Ukusetyenziswa kolawulo longqamaniso kwiPPK
Emva kokulawula ukulungelelaniswa kwekhamera, kwiprojekthi yokuhlola kunye nemephu, i-PPK ingasetyenziselwa ukunciphisa inani lamanqaku okulawula. Okwangoku, kukho iindlela ezintathu zokunxibelelanisa ikhamera ye-oblique kunye nePPK :
| 1 | Enye yeelensi ezintlanu inxulunyaniswe nePPK |
| 2 | Zonke iilensi ezintlanu ziqhagamshelwe kwiPPK |
| 3 | Sebenzisa iteknoloji yolawulo longqamaniso lwekhamera ukunika umva ixabiso eliphakathi kwiPPK |
Nganye kwezi zintathu iinketho zineengenelo kunye nezingeloncedo:
| 1 | Inzuzo ilula, into engalunganga kukuba i-PPK imele kuphela indawo ye-lens enye. Ukuba iilensi ezintlanu azidityaniswanga, kuya kubangela ukuba impazamo yendawo yezinye iilensi ibenkulu. |
| 2 | I-advanteji ikwalula, ukubeka indawo kuchanekile, into engalunganga kukuba inokujolisa kuphela iimodyuli ezithile ezahlukeneyo. |
| 3 | Iinzuzo kukubekwa ngokuchanekileyo, ukuguquguquka okuphezulu, kunye nenkxaso yeentlobo ezahlukeneyo zeemodyuli ezahlukeneyo. Ukungalungi kukuba ulawulo lunzima kwaye iindleko ziphezulu. |
Okwangoku kukho i-drone esebenzisa ibhodi ye-100HZ RTK / PPK. Ibhodi ixhotyiswe ngekhamera ye-Ortho ukufezekisa i-1: i-500 imephu yokulawula imephu ye-topographic-free, kodwa le teknoloji ayinakufezekisa ulawulo olupheleleyo-indawo yokufota i-oblique. Ngenxa yokuba impazamo yongqamaniso yeelensi ezintlanu ngokwazo ingaphezulu kokuchaneka kokuma kokwahlulahlula, ke ukuba akukho khamera ye-oblique yongqamaniso oluphezulu, umahluko wefrikhwensi ephezulu awunantsingiselo……
Okwangoku, le ndlela yolawulo lulawulo lwe-passive, kwaye imbuyekezo iya kwenziwa kuphela emva kokuba impazamo yongqamaniso lwekhamera inkulu kunomda osengqiqweni. Ke ngoko, kwimiboniso eneenguqu ezinkulu kuthungelwano, ngokuqinisekileyo kuya kubakho iimpazamo zomntu ngamnye ezinkulu kunomda,. Kwisizukulwana esilandelayo seemveliso zeRie series, iRainpoo iphuhlise indlela entsha yokulawula. Xa kuthelekiswa nendlela yokulawula yangoku, ukuchaneka kokulungelelaniswa kwekhamera kunokuphuculwa ubuncinane ngomyalelo wobukhulu kunye nokufikelela kwinqanaba le-ns!
