Masekonzi mashanu akawanda here kana kuti mashoma? Kunwa kofi inopisa hazvina kukwana, kutsvaira kadhi yako uye kuenda kubasa kwakawanda. Asi dzimwe nguva kunyangwe nekuda kwekunonoka kwakadaro, mitsetse inoumbwa panzvimbo dzekutarisa, kunyanya mangwanani. Zvino ngatizadzise zvinodiwa pakudzivirira COVID-19 totanga kuyera tembiricha yemunhu wese anopinda? Nguva yekufamba ichawedzera ne3-4 nguva, nekuda kweizvi mhomho ichaonekwa, uye panzvimbo yekurwisa hutachiona, tichawana mamiriro akanaka ekupararira kwayo.
Kuti izvi zvisaitike, unofanirwa kuronga vanhu mumutsara kana kuti otomatiki maitiro aya. Muchisarudzo chechipiri, zvakakosha kutora kutonhora kwevanhu vakawanda panguva imwe chete, pasina kuvaremedza nezviito zvekuwedzera. Izvi zvinogona kuitwa nekuwedzera vhidhiyo yekutarisa system uye ita zviito zvakati wandei kamwechete: tsvaga zviso, kuyera tembiricha uye kuona kuvepo kwemask. Takataura nezve mashandiro akadaro pamusangano wedu ""uye isu tichakuudza zvakadzama pasi pekucheka.
Kupi kunoshandiswa thermal imaging systems?
Mufananidzi wekudziya imagetsi emagetsi "inoona" muinfrared spectrum. Hongu, ichi chinhu chimwe chete kubva kumafirimu echiito nezve kumhanyisa akakosha masimba uye mafirimu nezvePredator, iyo inoyevedza inopenya mufananidzo wakajairwa mutsvuku nebhuruu toni. Mukuita, hapana chakajairika pazviri uye anoshandiswa zvakanyanya: mapikicha anopisa anoona nzvimbo uye chimiro chezvinhu zvinoburitsa kupisa uye kuyera tembiricha yazvo.
Muindasitiri, mapikicha anopisa agara achishandiswa kutarisa tembiricha pamitsara yekugadzira, zvishandiso zvemaindasitiri kana mapaipi. Kazhinji zvinopisa zvinopisa zvinogona kuonekwa zvakakomberedza perimeter yezvinhu zvakakomba: thermal imaging systems "ona" kupisa kunobudiswa nemunhu. Nerubatsiro rwavo, masisitimu ekuchengetedza anoona kupinda kusingatenderwe mune imwe nzvimbo kunyangwe murima rakazara.
Nekuda kweCCIDID-19, makamera ekufungidzira anopisa ari kuwedzera kubatanidzwa neiyo biometric identification masisitimu ekudzora kupinda. Semuenzaniso, yakabatanidzwa mu "Β» (mhinduro yakazara kubva kuRostelecom, iyo inogadzirwa uye inogadzirwa muRussia) michina yekufungidzira inopisa inogona kuyera kupisa kwevanhu, kutarisa mafambiro uye kuratidza vanhu vane tembiricha yakakwira.
Iko hakuna miitiro inosungirwa yekushandiswa kweanopisa ekufungidzira masisitimu muRussia, asi kune general , maererano nezvaidiwa kutarisa kutonhora kwevose vashanyi nevashandi. Uye magadzirirwo ekufungidzira anopisa anoita izvi ipapo ipapo, asingade mamwe maitiro kubva kuvashandi nevashanyi.
Masisitimu ekutepfenyura asiri ekubata tembiricha kuyerwa anoshanda sei
Nheyo yehurongwa ndeyekupisa kwekufungidzira kunosanganisira kupisa kwekufungidzira uye kwakajairwa makamera, ayo akaiswa mudzimba dzakafanana. Kana uri kufamba uchidzika nemukoridho uye kamera ine maziso maviri yakakurisa yakakutarisa kumeso, uyu mufananidzo wekupisa. MaChinese pranksters dzimwe nguva anoaita chena uye anowedzera "nzeve" diki kuti dziite senge pandas.
Nyore optics inodiwa kuti ibatanidzwe neBioSKUD uye kushanda kwealgorithms yekuzivikanwa kwechiso - kuona uye kutarisa kuwanikwa kwemidziyo yekudzivirira yemunhu (masiki) kune avo vanopinda. Pamusoro pezvo, kamera yakajairika inogona kushandiswa kutarisa kureba pakati pevanhu kana pakati pevanhu nemidziyo. Mune software, ruzivo rwevhidhiyo nezveyero mhinduro inoratidzwa mufomu rinozivikanwa kune anoshanda.
Kuti the thermal imager iite chete kune tembiricha yevanhu, inotova nealgorithm yekuona chiso. Iyo midziyo inoverenga tembiricha kubva kune thermal matrix panzvimbo dzakakodzera - mune iyi kesi, munzvimbo yehuma. Pasina iyi "sefa," thermal imager inogona kukonzera makapu ekofi inopisa, incandescent light bulbs, nezvimwewo. Mamwe mabasa anosanganisira kutarisa kuvepo kwemidziyo yekudzivirira uye kuchengetedza kure.
Kazhinji, pamusuwo wezvivakwa, thermal imaging system inosanganiswa nekuwana kutonga uye manejimendi masisitimu. Iyo yakaoma inobatanidza kune sevha, iyo inogadzirisa data inouya ichishandisa vhidhiyo analytics algorithms uye inoaendesa kune otomatiki opareta workstation (AWS).
Kana kamera inodziya yekufungidzira ikaona tembiricha yakakwira, saka kamera yenguva dzose inotora mufananidzo wemushanyi uye inotumira kune iyo control system yekuzivikanwa nedhatabhesi yevashandi kana vashanyi.
Calibration yeanopisa ekufungidzira masisitimu: kubva kune mareferenzi samples kuenda kumushini kudzidza
Kumisikidza uye kushanda kuyerera kusingabatanidze tembiricha kuyerwa, inowanzo shandiswa muviri mutema zvachose (ABL), iyo chero tembiricha inobata mwenje wemagetsi mumhando dzese. Iyo yakaiswa mumunda wekutarisa weiyo thermal imaging kamera uye inoshandiswa kugadzirisa iyo inopisa mufananidzo. Blackbody inochengetedza tembiricha ye32-40 Β° C (zvichienderana nemugadziri), iyo iyo michina "inotariswa" pese painoyera tembiricha yezvimwe zvinhu.
Hazvina kunaka kushandisa hurongwa hwakadaro. Saka, kuti mufananidzo wekupisa ushande nemazvo, muviri mutema unofanirwa kudziya kusvika kune tembiricha yaunoda kwemaminetsi gumi-gumi nemashanu. Pane imwe nzvimbo, thermal imaging complex yakadzimwa usiku, uye mangwanani mutema wacho akanga asina nguva yokudziya zvakanaka. Nekuda kweizvozvo, munhu wese aipinda mushift aive nematembiricha akakwira pakutanga kwekuchinja. Gare gare takazvifunga, uye ikozvino iyo thermal imaging system haina kudzimwa husiku.
Parizvino tiri kugadzira tekinoroji yekuyedza inotibvumidza kuita pasina iyo blackbody. Zvakazoitika kuti ganda redu riri pedyo nemaitiro aro kune muviri wakasviba zvachose, uye chiso chemunhu chinogona kushandiswa sechiyero. Tinoziva kuti vanhu vazhinji vane tembiricha yemuviri ye36,6 Β°C. Kana, semuenzaniso, iwe ukateedzera vanhu vane tembiricha yakafanana kwemaminitsi gumi uye wotora tembiricha iyi kuita 10 Β°C, ipapo unogona kuenzanisa iyo inopisa mufananidzo zvichienderana nezviso zvavo. Iyi tekinoroji, inoshandiswa nerubatsiro rwehungwaru hwekugadzira, inoratidza mibairo yakanaka - haina kuipa kupfuura thermal imaging systems ine blackbody.
Iko kuchiri kushandiswa kweblackbody, hungwaru hwekugadzira hunobatsira mukugadzirisa mapikicha anopisa. Icho chokwadi ndechekuti akawanda ekupisa ekufungidzira masisitimu anoda kuisirwa kwemanyore eiyo thermal imager uye kugadzirisa kwayo kumuviri mutema. Asi zvino, kana mamiriro achinja, kuenzanisa kunofanirwa kuitwa zvakare, zvikasadaro mapikicha anopisa anotanga kuratidza kutsauka kwetembiricha kana kuita kune vashanyi nekudziya kwakajairika. Manual calibration mufaro wakadaro, saka isu takagadzira module yakavakirwa pahuchenjeri hwekugadzira, iyo ine basa rekuona muviri mutema uye kugadzirisa zvese pachayo.
Zvinoita here kuzvivanza kubva kune algorithms?
Artificial intelligence uye muchina kudzidza kunowanzo shandiswa mune isingabatike biometrics. AI ine basa rekuona zviso murukova kuyera tembiricha, kuregeredza zvinhu zvekunze (kapu inopisa yekofi kana tii, zvinhu zvinovheneka, zvemagetsi). Zvakanaka, kudzidzisa maalgorithms kuziva zviso zvakapfeka masiki kwave kunofanirwa kuve kune chero system kubva 2018, kunyangwe isati yasvika coronavirus: kuMiddle East, vanhu vanovhara chikamu chakakosha chezviso zvavo nekuda kwezvikonzero zvechitendero, uye munyika zhinji dzeAsia vane nguva refu. akashandisa masks kudzivirira kubva kufuru kana smog yemudhorobha. Kuziva hafu-yakavanzika chiso kunonyanya kuoma, asi algorithms iri kuwedzera zvakare: nhasi neural network inoona zviso zvakapfeka masiki zvine mukana wakafanana segore rapfuura pasina masiki.
Zvingaite sekuti masiki uye zvimwe zvekuzvidzivirira nazvo zvaifanira kunge zvave dambudziko mukuzivikanwa. Asi mukuita, kana kuvepo kwemasikisi kana shanduko yebvudzi kana chimiro chegirazi kunokanganisa kurongeka kwekuzivikanwa. Algorithms yekuona zviso shandisa mapoinzi kubva paziso-nzeve-mhuno nzvimbo inoramba yakavhurika.
Izvo chete "kukundikana" mamiriro ezvinhu mukuita kwedu kunosanganisira kuchinja chitarisiko chemunhu kuburikidza nekuvhiyiwa kwepurasitiki. Mushandi mushure mekuvhiyiwa kwepurasitiki haana kukwanisa kupfuura nepakati: biometric processors havana kukwanisa kumuziva. Ini ndaifanira kugadzirisa iyo foto kuitira kuti kupinda nechiso geometry kushande zvakare.
Kugona kwe thermal imaging systems
Kuyera kwechiyero uye kumhanya kwayo kunoenderana nekugadziriswa kweiyo thermal imager matrix uye mamwe maitiro ayo. Asi kuseri kwechero matrix kune software: vhidhiyo analytics algorithm ine basa rekuona zvinhu zviri mufuremu, kuzivisa uye kusefa.
Semuenzaniso, iyo algorithm yeimwe yakaoma inoyera tembiricha yevanhu makumi maviri panguva imwe chete. Huwandu hweiyo yakaoma hunosvika ku20 vanhu paminiti, inokwana kuti ishandiswe kumabhizimusi makuru eindasitiri, nhandare dzendege uye zviteshi zvechitima. Panguva imwecheteyo, mapikicha anopisa anorekodha tembiricha ari chinhambwe chinosvika 400 metres nehuroi hwekuwedzera kana minus 9 Β°C.
Kune akareruka macomplexes. Zvisinei, vanogonawo kurarama nemabasa avo zvinobudirira. Imwe mhinduro ndeyekubatanidza iyo inopisa imager mune metal detector frame. Iyi seti yemidziyo inokodzera macheki ane kuyerera kudiki kwevashanyi - kusvika kuvanhu makumi mana paminiti. Midziyo yakadaro inoona zviso zvevanhu uye inoyera tembiricha nekururama kwe40 Β°C pachinhambwe chinosvika 0,5 mita.
Matambudziko kana uchishanda neanopisa mifananidzo
Kuyera tembiricha yevasiri-kusangana kwevanhu vari murukova haigoni kunzi yakakwana. Semuyenzaniso, kana munhu anga ari panze kwenguva yakareba mukutonhora kwekunze, pamusuwo mufananidzo wekupisa unoratidza tembiricha 1β2 Β°C yakadzikira pane chaiyo. Nekuda kweizvi, sisitimu inogona kubvumira vanhu vane tembiricha yakakwira kupinda munzvimbo. Izvi zvinogona kugadziriswa nenzira dzakasiyana, semuenzaniso:
- a) gadzira corridor yekudziya kuitira kuti vasati vayera tembiricha, vanhu vagadzirise uye vabve kure nechando;
- b) pamazuva echando, wedzera 1β2 Β°C kune tembiricha yevafambi vese vari kuuya - zvisinei, izvi zvichaita kuti avo vakasvika nemotokari vanyumwe.
Rimwe dambudziko ndere mutengo weiyo chaiyo thermal imaging system. Izvi zvinokonzerwa nemutengo wepamusoro wekugadzira thermal imaging matrix, iyo inoda kurongeka kwakaringana, germanium optics, nezvimwe.
