Chii chiri hyperscesscrecral iri kure kunzwa? Maitiro ehunyanzvi, zvikumbiro

August 23, 2024

Hyperscrecral Kure kure kwekurira ndiko kurira kwekunzwa tekinoroji, kushandiswa kwevazhinji vaneyirwe maElectramnetic. Mukunzwa kure, asi zvakare kwakakonzera shanduko yakakosha mune yekugadzirisa data uye yekuongorora ruzivo, zvekuti iyo yekutanga mune yakafara-yebhendi iri kure nekusagadzikana mune zvinhu zvisina kujairika, mune hyperscrecral yekunzwa inogona kuonekwa. Saka chii chiri chena? Zvinotanga neboka rinooneka rezuva.

Nei nyika ichiruramisa?

Kunyangwe iri kumaodzanyemba kwedenga kana shanduko yemwaka, nei tichinzwa kuti nyika ine mavara? Muraraungu uyo unobvisa mushure mezuva rekunaya unogona kutibatsira kugadzirisa mhinduro. Chiedza chezuva chaicho chakasanganiswa

Kuwedzera kune izvi mwenje wezuva zvakare une mwenje mune ultraviolet uye infrared wavelengths. Nekudaro, ruvara rumwe chete rwechiedza kumaziso edu zvakare ruvara rwemwenje rwakaoma rwechiedza rwakaiswa zviuru zvemapoka, izvo zviri kure nemhedziso yemaziso emunhu kusiyanisa. Panguva imwecheteyo, zvinhu zvakasiyana zvinoumbwa nezvinhu zvakasiyana uye makomputa avo, chimiro chechinyorwa zvakare chakasiyana, icho chinotungamira kune iyo wavelength yeakaratidzwa kana yakapararira pamusoro pechinhu chinoratidzawo chokwadi; zvinhu zvakasiyana mumatunhu akasiyana ezvinyorwa zvechiedza chechiedza chekuratidzira nzira yakanaka. Izvi zvakasiyana siyana zvinoshamisa zvezvinhu zvinoumba hwaro hwekuzivisa uye kuongorora hunhu hwezvinhu zvakasiyana muzvinyorwa zvinoshungurudza sainzi.

Kuti uwane kunyatsowana ruzivo rwechiedza muzvisikwa zvakasiyana, iyo Optical Remote Sensites yakatevedzana tekinoroji yekufungidzira tekinoroji uye yakapararira kubva pazvinhu zvakakamurwa zvisungo zvechiedza uchishandisa mafirita, Mashatiki, magirazi uye zvimwe zvinongedzo-zvinopenya, uye zvinangwa zvinoonekwa uye zviri kure kunzwa kwesimbe kune iyo spectral information ruzivo rwakagamuchirwa kubva pasi kana kubva pakuratidzira kana kupararira.

Pakutanga, kunzwa kwekunzwa kwevhu kwakashandiswa kufungidzira kwakawanda tekinoroji system, imwe neimwe chiteshi ine ruzivo rweNanometer Nekudaro, nezvinhu zvakafanana kana zvinhu zviri mumatunhu akasiyana, hunhu hwekuratidzira kwavo hunowanzofanana, sezvakaratidzwa mumhando iri pasi pemiti inongosiyana zvishoma pa960 Nanometers, uye kuti kusiyanisa pakati pemapoka emarudzi akasiyana emuti, kugadzirisa kwekufungidzira kusingasviki gumi nanometers inodiwa; Semuenzaniso, kuti urege kuzivikanwa kwematombo, kuitika kwezvipembenene nezvirwere zvezvirimwa, ivhu rave kugadziridzwa pakurima, nekubuda kweFlora. Zvirwere, ivhu rekuvandudza, ruva renzou kana kurwiswa kwemvura, kusvibiswa kwemhepo uye zvimwe zvinetso zvevashoma vekuchinja .

Nekutanga kwekuvandudzwa kwelsercaling kure nekuona tekinoroji muma1970s, iyo munda weOptical kure nekuchinja kwekuchinja uye zvishoma nezvishoma kwakaumbwa tekinoroji yekunyepedzera. Hyperscrecral Remote Sensing Technology ndeye tekinoroji yakavakirwa pane tekinoroji yemhando yepamusoro yekufunga nezvechinangwa chevhu uye chimwe-chinongedzo chekutanga chechinangwa, uye kuwana kuenderera mberi, kutetepa-bhendi Image data ine yakakwirira yekugadzirisa resolution. Hypersliscal kufungidzira tekinoroji iri kukurumidza kufungidzira, uye izvo zvakajairika zvinosanganisira kurongedza spectroscopy, acousto-optic tunable filter spectroscopy, prism spectroscopy, uye chip yekuvhara.

Ndeapi maitiro ehunyanzvi ekufungidzira ari kure kure nekunzwa?

Hyperscalral ( hypersciscral kamera ) single-channel bhendi yakakwira, kugadzirisa kwayo kwakakwirira kunge nmanmeter Kuenderera mberi kwekuratidzira

Kusiyaniswa kubva kune iyo yetsika kuwanda kwekuratidzira tekinoroji yekusaita tekinoroji yemhando, uye zvinangwa zvacho zvinogona kusiyanisa kazhinji izvo zvine misiyano iri pachena mumuviri wekupindirana, senge miviri yemvura , zvinomera, uye zvisina chinhu. Hyperscrecral Miripo Sensing inzvimbo yehuwandu hwehuwandu hwehuwandu hwehuwandu hwekuwana ruzivo runosanganisa tekinoroji uye ruzivo rwechinyakare ruzha rwechinangwa, uye ongorora ruzivo rwekuenzanisa rwezvinyorwa kuburikidza neiyo morphology ye Iyo spectral curves yekuziva iyo tarisiro pamwe nezvinhu zvinangwa, izvo zvinogona kusiyanisa mapoka akasiyana ezvinyorwa zvakafanana. Zvinoenderana nemabasa akasiyana ekushandisa, kusarudzika kweiyo spectrum inozochinja uye kusiyanisa, inovandudza mamiriro ekusiyanisa uye nekuziva mapoka akafanana, anoziva kuti "akasiyana spectra yerudzi rwakati" uye "Zvimiro zvakasiyana zvemhando imwecheteyo yemhando", uye inoderedza chiitiko chekuvhiringidzika kwenzvimbo dzekuvhiringidzika kwezvinhu zvemafungiro, zvakadai sechiitiko chemarudzi akasiyana emuti. Inogona kuderedza chiitiko chekupindira kwepasiridzo yemhando, sekuzivikanwa kwemarudzi akasiyana emuti uye michuru dzakasiyana; Panguva imwecheteyo, hyperscessctionral data inogona kushandiswa pakurwiswa kweiyo bio-yemuviri uye yemakemikari parameter, uye kuongororwa kwe biochemical, lignin uye cellulose zvinomera.

Iko kuvandudzwa kwelsercrecral iri kure nekuona tekinoroji inoita kuti kuregedza kuregedza kuregera tekinoroji yekufungidzira Yakanakira, iyo iri pachena ine hukama neyekufungidzira sensor's Sensor's Spectral uye yekukanganisika uye ivhu rekusimbisa uye mamwe mafungiro Kupwanyika kuburikidza nekukasira kwekufungidzira kwekugadzirisa, izvo zvinonyanya kudzvinyirira pesvedzero yezvimwe zvinhu zvinoshungurudza mumamiriro ekunze, izvo zvinobatsira kwazvo pakuvandudzwa kwekuongorora kwehuwandu.

Ndezvipi zvirimo malerscesscaly?

Kuenzaniswa neyekumusoro-resolution uye akawanda-spectral mifananidzo ine zvifananidzo zvakakwirira uye zvisungo zvakawanda, uye zvisikwa zvingangoitika zvinogona kusarudzwa kana kubviswa maererano nekudikanwa kwekusimbisa chinangwa chevanotarisa; Iyo yakazadzwa kuenderera mberi kwekuratidzira data kugovera mamiriro ekutanga kwekutanga kwemifananidzo mune iyo spectral mecheni yemhando yezvinhu, iyo ine yakapfuma redometric, spateral ruzivo, uye iri synthesis ruzivo rwakasiyana siyana. Iyo ine yakapfuma radiometric, spatial uye spectral ruzivo, uye iri kutakura kwakakwana kwemashoko akasiyana siyana. Mifananidzo inoyevedza inoshandiswa zvakanyanya muminda yeGeomorphological mepu, rurtuce yekutsvaga, yemamiriro ekunze ekuratidzira, ivhu riri kure, ruvara rwemvura kure nenyanzvi yekunzwa uye yeturmirec sainzi.

1. REMOTE KUNYENGETSA YEMAHARA YEMAHARA

Iyo nhamba inoratidza iyo hyperscaldal data yeDubai yeDubia nzvimbo inowanikwa nelpersciscrair in sensors, senge miviri yemvura, zvivakwa, migwagwa, nezvimwewo, kuburikidza neFeature Classification, uye inogona kuve Subdived mu3 ~ 5 inoshanda subcategories mune imwe neimwe huru chikamu, uye inogona zvakare kuziva ruzivo rwemidziyo mugungwa riri kure.

2. Ore kuongorora

Hyperscrecral Remote Sensing Tekinoroji inogona kupa kuwedzera kusimudzira kune geological kuongorora. Zvichienderana nekuongororwa kwemapururu ematombo akawanikwa, mhando dzekuparadzira mineral uye nzvimbo yenzvimbo inogona kuzivikanwa. Mufananidzo uyu unoratidza kuti humbowo kure kure kunzwa kwedata zvakanyatsotsausa marudzi maviri emaminerari eSersicite yeQinghai yeQinghai, uye mushure mekushandurwa kweMNF. Inowedzera kuzivikanwa kweiyo lithology uye teconic geology ruzivo.

3. Remote kunzwa kwenzvimbo yemvura

Nekuda kwekufanana kwekufanana pakati pezvirimwa zvemvura uye maruva emvura uye zvido zvemvura uye zvakaomarara kuti zvive nyore kushandisa marara emvura uye zvirimwa zvemvura, uye chete hyperscrection yekunzwa data inogona kutora data inogona kutora iyo Zvakaringana zvekupfungaira pakati pemvura yakaoma uye inoyerera mvura yemvura, zvirimwa zvemvura, uye muviri wemvura, kuitira kuti zvinyatsozivisa maruva emvura uye zvidyarwa zvemvura. Nhamba yacho inoratidza mepu yeYunnan Dianchi mudunhu remvura akawana neiyo satellite inonyungudutswa inonyungudutswa (CDOPH) mumuviri wemvura. Zvichakadaro, iyo mvura yemvura yemvura yenzizi diki uye madziva kunze kweDianchi anozivikanwa zvakajeka mumufananidzo.

4. Atmpheric kure kure kunzwa

Remote Sensing Kuongorora kweMethene Point Manness Mufananidzo (a) unoratidza mhedzisiro yekuongorora methane kubva kuDor Marado Mafuta zvakanaka muLibya kubva kuDSNGE kubva kuDCMCE WOCE MUNYAYA YEMAHARA. Tarisa uone methane yakajeka emission plame mudunhu.
