Chii musiyano uripo pakati pekufunga, multarical, uye hyperscrecral

August 23, 2024

Spectral, llersciscral, malerscesscrecral, haigone kutaura mutsauko?

Kuongorora kwekunyepedzera senzira yakakosha yekuongorora Science Ongcial Ongorora, tekinoroji yekufungidzira inowanzoshandiswa kuona chimiro chemuviri, chemakemikari uye zvimwe zviratidzo. Image spectrometry, kune rumwe rutivi, inosanganisa spectral tekinoroji uye kufungidzira kwekugona kwekugadzirisa, zvinokonzerwa nekufungidzira kwekufungidzira, iyo yave kuzivikanwa seyekufungidzira kufungidzira uye kufungidzira kwekufungidzira tekinoroji.

Ndeupi musiyano uripo pakati pekupindira, multersaldal uye hyperscrecral?

Spectrum

Spectrum ndiyo Monochromatic mwenje nekupararira mushure mekuparadzira system (yakadai semafashoni, kubudikidza nehurongwa hwekufunga kuti rive rirongwa (kana frequency) saizi yeiyo gadziriro yeiyo nzira, iyo inozivikanwa se iyo Optical spectrum. Ocean Optics Spectrometer yakavakirwa pane iyi nheyo yekugadzira uye kugadzira.

Mafungu echiedza maererano neakasiyana wavelengths, kune mazita akasiyana: Uye akareba kupfuura 780nm yeiyo infrared mwenje (Chiedza Chiedza chinogovaniswawo muzvikamu zviri pedyo, zvepakati-infrared, infrared, nezvimwewo).

Vaperevha

Tekinoroji yemufundisi inoreva nezvekutora panguva imwe chete yemitambo yakawanda yekupindirana Nzira yakajairika yekuziva iri kuburikidza nemhando dzakasiyana-siyana dzemafirimu , kuti utore chinangwa mumabhandi akati wandei akasiyana emifananidzo. Iyo inowanzoitika multincentral photo yakatenderwa ndeyekutakurwa ne car cam Kana mamwe mabhendi akawedzerwa kune kamera kana detector, senge mabhendi (4) uye (5), mufananidzo unoridza mabendi akawanda anogona kuwanikwa.

Multi-Spectral Technology yakasanganiswa nekufungidzira Hardware inobvumira ruzivo rwakawanda-ruzivo kuti rwunziwe mune yemifananidzo fomu.

Ehezve, zvinokwanisikawo kushandisa chete iyo chete detector kuti uwane iyo yekufungidzira ruzivo rweimwe spatial point. Pixelteq, rudzi rwemakungwa exics

Hypespecral

Hypespecal inyanzvi yakanaka inokwanisa kutora uye kuongorora iyo spectra point neenzvimbo yenzvimbo, nekuda kweiyo yakasarudzika nzvimbo yenzvimbo dzechinhu chimwe, uye saka inogona kuona zvinhu zvisina kujairika zvisingagone kusiyaniswa zvinoratidzika.

HyperscalCral Muenzaniso: Mifananidzo inosanganisira marara mhanza (10-20 nm). Mifananidzo inoyevedza inogona kunge ine mazana kana zviuru zvezvikwata. Mushure mechinhu chinopindirana nechiedza kubva kune mwenje wechiedza uye chinogamuchirwa neyekufungidzira kusarudzika kwekuongorora chishandiso (semuenzaniso, chishandiso chacho chingaitwe nekuparadzaniswa kwechiitiko chechiitiko pamusoro pemasendimita ekutarisa zvakare inozivikanwa semuenzaniso ruzivo. Paunenge uchishandisa mafungiro ekufungidzira, kubva pamaonero ekufungidzira maitiro, unogona kunzwisisa ruzivo rwese rwemuenzaniso, kubva pamaonero emuenzaniso, unogona kunzwisisa kugoverwa kwechiratidzo mune imwe sumo yekutanga, ndiko kuti, Hyperscalcral midziyo inogona kuwana hupfumi ruzivo ruzivo. Semuenzaniso: Ziso revanhu rinogona kungogamuchira mapoka matatu ekupindira mune chinhu chechiedza chesimba chiratidzo: tsvuku, girini uye bhuruu. Ndokunge, taiwanzotaurwa nezvemavara matatu ekutanga, asi muchokwadi tinokwanisa kuona musanganiswa uyu mavara matatu anogadzirwa neorenji, yepepuru, lime yakasvibira uye zvakadaro pane zvakawandisa mavara. Nekudaro, isu hatikwanisi kusiyanisa mutsauko pakati peiyo yakachena yero uye musanganiswa wetsvuku uye girini, inozivikanwa zvakare se "Isochromatic". Asi mafungiro ekufungidzira anogona kusiyanisa zviri nyore mutsauko.

Pamusoro, iyo maviri ellows, imwe ye "ruvara rwakasimba" uye mumwe musanganiswa wetsvuku uye wakasvibira, zvinogona kunge zvisingaonekwe, asi nekuda kwekunetseka kwavo kwekufungidzira, ivo vanogona kusiyanisa kushandisa mashandiro emidziyo. Mukuedzwa kwedu, iyo data yakawanikwa neyekufunga nezvechiedza chakaburitswa nemamolekyudhi ese anowoneka neyakawonekera Zvisungo zvakananga pane dzakasiyana-siyana mapoinzi mukati meiyo yakaonekwa renji. Nekuda kweizvozvo, hapana kana midziyo iyi inogona kupa ruzivo rwakanaka kwazvo rweenzaniso mune imwe nzvimbo.

A hsifiscalcyral image (HSI) inogona kuidzwa kumazana kana zviuru zvevaridzi-point-point spectrometer pamwe chete uye nekutarisa kune imwe nguva yekuzvimirira ichishanda yakazvimirira uye yekuwana ruzivo rwekufunga nezvenzvimbo yayo. Iyo data yekubuda kubva kuHSI mufananidzo, kana vhidhiyo rwizi, mune iyo pixel yega yega ine spectrum, uye chiyero chimwe nechimwe chine mazana emazana emabhandi ekupindwa. Iyi "yakazara-spectrum" kugona kweiyo hyperscessral kufungidzira kunoita kuti munhu aone zviratidzo zvekupindurudza kunzvimbo dzese dzinoyevedza nzvimbo mune chiitiko, ie, ruzivo rwakawanda rwakawanikwa. Naizvozvo, mafungiro ekufungidzira anogona kushandiswa mune dzakasiyana siyana zvekushandisa, kusanganisira kuzivikanwa kwehunyanzvi, masango, madashama, maindimi uye zvigadzirwa zvemumaindasitiri mumitsara yekugadzira, kutarisa kwezvakatemerwa, uye zvimwe.

Hyperslessral inotarisa nzira uye kufungidzira mhedzisiro

Mutsauko uripo pakati pekunyepedzera uye kuwanda

Kazhinji kacho kuratidzwa kwehunhu hwezvinhu zvinogona kuve zvakaoma zvakanyanya neruremekedzo kune wavelength

Zvinhu izvo zvaive zvisina kuzivikanwa kubva kune izvo zvinoratidzwa uchishandisa kufungidzira kwehuwandu (kuruboshwe) mumufananidzo uri pamusoro kwakasarudzika kuburikidza nekushandiswa kwekufungidzira (kurudyi). Chikonzero cheichi ndechekuti nekuti vayelsercredal vane mamwe mabandi emitero, akaomesesa zvigunwe zveminwe anogona kunyatso kuwanikwa nekugadzirisa kwakakwirira.

Chaizvoizvo Zvikumbiro

Mahwendefa ezvimbiso anogona kuona chaiyo pendi kana dhayi mune infrared iyo isingaonekwe neziso remunhu. Saizvozvo, HSI masisitimu ari mu60 kana 300 bhendi inogona kupa hupfumi hwekufunga nezvechiratidzo chechinyorwa pane hurongwa hwekuwedzera, uchibvumira zvimwe zvinonyatsonaka. Mufananidzo uri pazasi unoratidza iwo mufananidzo uye spectral ruzivo rwakawanikwa kubva pachidimbu chemhuka nyowani yakaiswa pane bhandi rebhandi mune hyperscalciscal:

Mapepa ematunhu akasiyana: (a) akanyorwa matunhu ezvemafuta akachena, anokwenenzverwa uye akachena lean zvikamu pamatehwe ematehwe; (b) Spectrograms yakanyorwa munzvimbo dzakasiyana dze (a) dhizaini.

Mukuwedzera isu tinogona kupa intuitive software zvirongwa zvekufungidzira, kuiswa uye kuona kwezvinhu zvakasiyana nezvinhu zvakasiyana. Kunyangwe iyi data inowanikwa kubva kumhepo, pasi, kana muLab, iwe unogona kuona zvinhu pakombuta yako inogona kunge isiri kusiyanisa neziso.
