Face kuonekwa kushandisa vhidhiyo nokuongororwa enyika. Search algorithm vanhu

Software uye Hardware nokuda yepamusoro revatema kuchengeteka hurongwa vanokwanisa kugadzirisa matambudziko chero kunzwisisa pane ose maindasitiri, munzanga uye mudzimba zvinangwa. Zvikuru midziyo kuchengeteka gadziriro iri vhidhiyo zvokuongorora hurongwa, uye zvinodiwa kuti functionality ari chidimbu, iri kukura zvishoma nezvishoma.

Integrated kuchengeteka hurongwa

Single kuchikuva Integrated kuchengeteka hurongwa kunosanganisira modules moto-kudzivirirwa zvokushandisa, kuwana kuzvidzora, CCTV, kana akavharika wedunhu terevhizheni (kamubhedha). wokupedzisira basa kusvikira ichangopfuura akanga hakugumiri pavhidhiyo zvichiongororwa uye kunyora zvinhu panguva nzvimbo uye nzvimbo dzakapoteredza, archiving uye okuchengetera zvinhu. Classic Video hurongwa vane uwandu payakaipira:

• The chinhu kwevanhu. Va neudhadha basa opareta iri shanduro hombe Vhoriyamu mashoko.
• The chisingabviri wokuvhiya uye kukodzera kuongorora.
• Nouchapupu nguva kutsvaka uye kuziva chiitiko.

Kukura digitaalinen Michina zvakakonzera kusikwa "akangwara" zvoga hurongwa.

Simba iri pfungwa

Inokosha noungwaru mavhidhiyo zvokuongorora kwava Video analytics - michina yakavakirwa nzira uye algorithms mufananidzo pamutemo uye mufananidzo kubudiswa, otomatiki muunganidzwa mashoko semubairo ongorora vhidhiyo. Zvombo zvakadaro pasina kugona kwevanhu kuona uye njanji huru panzvimbo nguva chaiyo (motokari, rimwe boka revanhu), mamiriro ezvinhu anogona kuva nengozi (utsi, moto, kunze komutemo kupindira mukushanda mavhidhiyo makamera), chiite zviitiko, uye kunokonzera mhere iri nenguva nenzira. By inonzwika apo vhidhiyo Data havasi kufarira zviri kuderedzwa mutoro pamusoro kukurukurirana hova uye zvakachengetedzwa Database.

The vakatsvaka-akawanda achishandisa mavhidhiyo analytics - chiso pamutemo hurongwa. Zvichienderana mabasa avo uye mabasa kuti Hardware inofanira kusvitsa zvimwe zvinodiwa.

Software uye Hardware

For vakarongeka kushanda hurongwa vanoshandisa mhando dzakawanda IP-makamera nedzimwe uchishandisa maitiro. Chinhu kuonekwa munzvimbo ndee muna kudzorwa mukamuri Panoramic maonero pamwe chisarudzo 1 M uye muzinda urefu pakati 1 mm uye kunyengedza iye kushanda pakuvheneka namano. Izvi nani kamera (2MP inobva 2 mm), inobereka kuziva nyore nzira (parameter 3-4). Nokuti kuziva chinhu uchishandisa kamera nezvakanaka yepamusoro mufananidzo, zvakakwanira kushanda algorithms kunzwisisa (5 MN, 8-12 mm). The inonyanya kufarirwa Software kuti chiso pamutemo "Face Akangwara" (the yokuvaka - kambani House Control), Face Director (kambani "Synesis) uye VOCORD FaceControl (VOCORD) ratidza:

• High fungidziro yokuziva chinhu (kusvika 99%).
• Vatsigire-siyana pamakona ose vachishandisa kutenderera Camera.
• Mukana allocating vanhu, kunyange gobvu chime uremu.
• Variability drafting Analytical mishumo.

Kunyatsogona muenzaniso kuzivikanwa

Chero biometric pamutemo hurongwa dzinobva kuziviswa kwemashoko unoenderana achiona kuti vasiri zvechadenga munhu pakutsvaga akafanorongerwa muenzaniso. Kushanda pakuvheneka kunoitika munguva-zvechokwadi nguva. IP-kamera transmits imwe vhidhiyo kuti chirwere, uye chiso kuzivikanwa hurongwa rikasarudza kuti mufananidzo anochengeterwa Database mifananidzo. Pane huru nzira mbiri. Chokutanga hunobva kunofambira mberi misimboti: migumisiro kubudiswa biometric parameters, wemagetsi mharidzo iri muchimiro nedzimwe nhamba chaienzanirana imwe munhu. nzira yechipiri simulates munhu "munhu" nzira uye kunoratidzwa nokuzvidzora kudzidza uye robustness. Personal kuziva vhidhiyo mufananidzo kunoitika, kufungisisa zera-chokuita kuchinja, uye zvimwe zvinhu (kuvapo headgear, ndebvu kana mustaches, magirazi). Michina iyi inobvumira kushanda kunyange mifananidzo akwegura uye, kana zvakakodzera, pamwe X-ray.

Search algorithm vanhu

Nzira inonyanya kuti Detective vanhu - kushandisa Haar Cascades (anoita Masiki). The chifukidzo chinhu rectangular bhokisi ane zvakasiyana siyana zvikamu vatema uye chena.

The mashandiro wepurogiramu riri sezvinotevera: vhidhiyo puranga rinosanganisira chine zvifukidziro, uye migumisiro yacho convolution (tichiverenga pixels chomumwe sectors matema uye chena) vari dzaona musiyano anofananidzwa neumwe pachikumbaridzo ukoshi.

Kuvandudza mabasa ari classifier akanaka (mapuranga apo pane zviso zvevanhu) uye kunaka (pasina pavo) ivhu pakudzidza. Muchiitiko chokutanga kuti convolution mugumisiro uri pamusoro pachikumbaridzo mutengo, wechipiri - pazasi. Individual detector pamwe kukanganisa zvinobvumidzwa anosarudza uwandu mumatanho ose convolutions uye kana kupfuura rinoratidza kuvapo vanhu vari pamatanda.

pamutemo Michina

Mushure kuonekwa uye localization pamusoro rokutanga nguva, luminance uye geometric inogara mufananidzo. Uyezve zviito - kukarukureta kwezviratidzo uye kuzivikanwa - zvinogona kuitwa nzira dzakasiyana-siyana.

Kushanda pakuvheneka chiso yakazara chiso muimba yakanaka chiedza nemigumisiro yakanaka inoratidza algorithms kushanda maviri-dimensional mifananidzo. Kuongorora yakasiyana pfungwa uye daro pakati pavo, chiso vasabatwa hurongwa anoona chokwadi kuti kuziva coefficients pakati kusiyana mufananidzo "mhenyu" uye vakanyorwa template.

Three-dimensional Michina nemishonga kuchinja luminous zvinoyerera kubva zvinobvumidzwa zvokutsauka yorusvingo kubva mberi - kuti madhigirii 45. Pano, kwete chete kuongorora pachena pfungwa uye mitsetse, asiwo ehupfumi nechepasi (curvature Profile) arşive marefu therebetween. Kushandisa algorithms vakadaro vanoda chemhando yepamusoro vhidhiyo pa mapuranga anosvika 200 / chik. The Hurongwa kunobva redhiyo, aine chizvaro 5 megapixels, yakakwirira Manyiminya chisarudzo uye kurerutsa yaunonyanya kushandisa kukanganisa. Uyezve, vari zvakabatanidzwa ne chinokosha netambo nokuda nokupfuuridzirwa nguva wachi.

Mamiriro ano pamusika nehurongwa

Yokutanga biometric Hurongwa, nokuda kwavo kudhura, vave akakudziridza chete hurumende uye vemauto zvivako chete pakati pezana 90s vakava kuwanikwa nevemabhizimisi. Kukurumidza kukura ruzivo uye microprocessor michina yakawedzera rakarurama hurongwa uye kuti vawedzere chadzo. Pamisika munyika zvichiita nzvimbo ndezvedu vagadziri American uye Western Europe yokuchengeteka enyika. Sales Mutungamiri vesangano midziyo ZN Vision Technologies uye Visionics. Chinonyanya vaizotibata pazvipfuwo Developers kutarira kutsvakurudza uye zvigadzirwa makambani "Vocord", NTechLab, "Soling", LLC "VizhnLabs" uye "MDGs", iro, pakati pezvimwe zvinhu, kuita zvakawanda uye kwadzakabva vokune dzimwe nyika gadziriro kusvika mamiriro Russian.

kombiyuta facecontrol

Nzvimbo dzakawanda chaizvo nokushandisa contactless kuzivikanwa - pakurwisa ugandanga uye mhosva. Image akutadzira zviso mudura Database. In nzvimbo vakawanda kuungana (dzendege, pazviteshi, zvitoro centre, mitambo zvivako) anokanda aibuda vanhu nguva chaiyo kuti tizive vanhu vari aida.

Akatevera bhora - Access Control System: The mharidzo mifananidzo electronic vanopfuura rinofananidzwa ne muenzaniso, kunoguma mashoko kubva Camera. The nzira kunoitika panguva pasina anoda kupfuura kuzombotaurazve chiito (kusiyana kune the retina Ongororo kana fingapurindi).

Mumwe kukurumidza kukura bhizimisi - kumusika. Dyidzana billboard achava tarisei chiso munhu, anosarudza kurara kwayo uye zera, visualizes chete shambadzo kuti zvichava angangoita dzinonakidza nokuda nemhosva.

Trends uye Inofadza

Zviri mukurumbira chaizvo chiso kuzivikanwa wemuTesitamende rwezvemabhengi zvekutepfenyura. Gore rakapera, utungamiriri "Post Bank", pashure kuisa pamabasa avo 50,000 akangwara makamera, aigona kuponesa mamiriyoni rubles nokuda kudzivirira kubiridzira mune anomukweretesa uye muripo zvikamu. Nyanzvi dzinoti kubudikidza 2021, achasika zvinokosha kwezvivako network, uye chero kushandiswa ATMs vachava zvinogoneka chete pashure biometric kuziva pamusoro nemhosva.

In gumi anotevera mukuru Michina kuchaita kuzarura ngetani kuzvitoro azere dzokuzvikoshesa basa: The mutengi anoenda mahwindo shop, sarudza zvigadzirwa kubva pamabhuku uye mashizha. vanhu uye muenzaniso kuzivikanwa hurongwa anosarudza kuzivikanwa mutengi, kutenga uye nyora kure munhoroondo runodiwa uwandu.

Basa riri kuitwa kuti pave kwegadziriro kuziva mupfungwa mamiriro. Analysis manzwiro evanhu vachava kudiwa ari Multimedia munzvimbo: akachangamuka, firimu, maindasitiri, asika mitambo yepakombiyuta.
