Hangarau Mōhio Kanohi i roto i ngā Pūnaha CCTV Hou
Pendahuluan
I te tere o te whanaketanga o ngā hangarau mōhiohio me te whakawhitiwhiti kōrero, kei te piki haere hoki te hiahia mō te haumarutanga. Kua roa te whakamahinga o te aroturuki Pouaka Whakaata Porowhita Kati (CCTV) hei tikanga tirotiro whai hua. Heoi, i te whanaketanga o te hangarau mōhio kanohi, kua matatau ake, kua whai hua ake hoki ngā pūnaha CCTV ki te kimi me te tātari i ngā mahi e aroturukitia ana. Ka matapakihia e tēnei tuhinga te whakamahinga o te hangarau mōhio kanohi ki ngā pūnaha CCTV hou, ōna painga, me ngā wero e pā ana ki a ia.
Hītori o te Mōhio Kanohi i roto i ngā Pūnaha CCTV
Ehara i te mea hou te hangarau mōhio kanohi. I tīmata te rangahau mōna i te tekau tau atu i 1960, engari i taua wā, he iti noa iho tōna tika me tōna whakamahinga. Nā te whanaketanga o te rorohiko me ngā rauropi ako mīhini, kua tere te whanaketanga o tēnei hangarau, inā koa i te tīmatanga o te rautau 21.
I te tīmatanga, ko ngā pūnaha CCTV anake i whakamahia hei hopu whakaahua me ngā ataata. Heoi, i te tipu haere o te hiahia mō te haumarutanga me te tirotiro, kua whakauruhia te hangarau mōhio kanohi hei kimi aunoa me te mōhio ki ngā tāngata i roto i ngā kiriata CCTV. Mā tēnei whakaurunga ka nui ake te atamai me te arotau o ngā pūnaha CCTV.
Te Mahi a te Hangarau Mōhio Kanohi
Ko te mōhio kanohi he hangarau e āhei ai ngā rorohiko ki te mōhio me te manatoko i ngā kanohi tangata mai i ngā whakaahua, i ngā ataata rānei. He maha ngā mahi kei roto i tēnei tukanga, tae atu ki:
1. Te Kimi Kanohi:
Ka kitea e te pūnaha te aroaro o ngā kanohi i roto i ngā whakaahua, i ngā ataata rānei. Ko te tikanga, ka mahia tēnei mā te whakamahi i ngā hangarau tukatuka whakaahua me ngā rauropi kimi kanohi pēnei i a Haar Cascade me MTCNN (Multi-task Cascaded Convolutional Networks).
2. Tangohanga Āhuatanga:
I muri i te kitenga i tētahi kanohi, ka tangohia e te pūnaha ngā āhuatanga ahurei o te kanohi, pērā i te tawhiti i waenga i ngā kanohi, te āhua o te ihu, me te hanganga o ngā paparinga. Ko te tikanga ka hurihia ēnei āhuatanga hei whakaaturanga tau (te tohu whārite).
3. Te Whakataurite Kanohi:
Kātahi ka whakaritea ngā āhuatanga kua tangohia ki ngā raraunga kanohi kua rongoatia kētia i roto i tētahi pātengi raraunga. Ka whakamahia ngā rauropi ako mīhini me te ako hōhonu, pērā i te Convolutional Neural Networks (CNN), hei mahi i tēnei taurite me te tino tika.
4. Manatoko, Tāutu rānei:
I te wāhanga whakamutunga, ka manatoko te pūnaha i te tuakiri kanohi mēnā e ōrite ana ki ngā raraunga kei roto i te pātengi raraunga. Mēnā kāore he ōritenga, ka taea e te pūnaha te tuku whakamōhiotanga, te mahi rānei i tētahi mahi kua whakaritea i mua.
Ngā Painga o te Hangarau Mōhio Kanohi i roto i ngā Pūnaha CCTV
He maha ngā painga o te whakaurunga o te hangarau tirotiro kanohi ki roto i ngā pūnaha CCTV hou, tae atu ki:
1. Whakapai ake i te Haumarutanga:
Mā te mōhio kanohi ka taea te tautuhi i te hunga e tomo ana ki tētahi wāhi motuhake i te wā tūturu, te kite i ngā tūmomo mōrearea pea, me te aukati i te hara i runga i te huarahi whai hua.
2. Aroturuki Whai Hua:
Mā te mōhio kanohi, kāore e hiahiatia ana e ngā kaiwhakahaere CCTV te tirotiro ā-ringa i ngā aroturuki hei tautuhi i ngā tāngata takitahi. Ka kitea aunoatia e te pūnaha, ā, ka tukuna ngā whakamōhiotanga i runga i ngā tawhā kua whakaritea.
3. Rapunga Tere:
Mā tēnei hangarau ka taea te rapu tere me te tika i ngā kanohi i roto i ngā kiriata, ā, ka taea ai te whakahaere i ngā rangahau mō ngā aituā taihara, ngā tāngata ngaro rānei.
4. Whakawhaiaro:
I ētahi whakamahinga, pērā i ngā toa hokohoko, i ngā hōtēra rānei, ka taea te whakamahi i te mōhio kanohi hei whakarato ratonga whaiaro ake mā te tautuhi i ngā kiritaki auau me te whakarite i te ratonga e whakawhiwhia ana ki a rātou.
Ngā Wero i te Whakatinanatanga o te Mātakitaki Kanohi
Ahakoa ngā painga maha, kei te whakamahia tonutia te hangarau tirotiro kanohi i roto i ngā pūnaha CCTV, tae atu ki:
1. Te Matatapu me ngā Tikanga Matatika:
Ko te whakamahinga o te hangarau tirotiro kanohi e ara ake ana i ngā āwangawanga mō te tūmataitinga o te tangata takitahi. He maha ngā tāngata e kore e pai ki te whakaaro ka taea te aroturuki me te tuhi i ā rātou nekehanga katoa.
2. Haumarutanga Raraunga:
Ko te penapena i ngā raraunga koiora pēnei i te kanohi me whai taumata haumarutanga teitei hei ārai i te whakamahi hē, i te turuturu rānei o ngā raraunga.
3. Te tika:
Ahakoa kei te whanake tonu tēnei hangarau, ka pā tonu ngā āhuatanga pēnei i te mārama, te koki kāmera, me te kounga o te ahua ki te tika o te kimi me te tautuhi kanohi.
4. Te Whakahāwea me te Whakahāwea:
Tērā pea kei roto i ngā rauropi mō te mōhio kanohi ngā whakaaro whakahāwea ka arahi pea ki te whakahāwea i ētahi rōpū. Me whakahaere te whakawhanake me te whakangungu i ngā rauropi me ngā raraunga kanorau hei whakaiti i tēnei whakaaro whakahāwea.
Te Whakatinanatanga i roto i ngā Rāngai Rerekē
Kua whakamahia te hangarau mōhio kanohi i roto i ngā pūnaha CCTV i roto i ngā rāngai maha, pēnei i:
1. Te Haumaru ā-Iwi:
I roto i te maha o ngā tāone nui, ka whakamahia ngā pūnaha CCTV me te tohu kanohi hei aroturuki me te tautuhi i ngā kaihara, hei rapu i ngā tāngata ngaro, me te whakapai ake i te haumarutanga i ngā wāhi tūmatanui.
2. Te kawe waka:
Ka whakamahia tēnei hangarau e ngā taunga rererangi me ngā teihana tereina hei manatoko i te tuakiri o ngā pāhihi me te whakapai ake i te whai huatanga o te tukanga ekenga.
3. Pēke:
Ka whakamahia e ngā peeke te mātakitaki kanohi hei manatoko i te tuakiri o te kiritaki i runga i te ratonga-whaiaro, i ngā ATM, me ngā tono peeke pūkoro.
4. Hokohoko:
Ka whakamahia e ngā toa hokohoko te mātakitaki kanohi hei tātari whanonga a ngā kaihoko, hei ārai i te tahae, me te whakawhaiaro i te wheako hokohoko.
Te Anamata o te Hangarau Mōhio Kanohi
E matapaetia ana ka whanake tonu te hangarau mōhio kanohi, me te whakapai ake i te tika, te tere tukatuka, me te whakauru atu ki ētahi atu hangarau pēnei i te matauranga horihori (AI) me te Ipurangi o ngā Mea (IoT). Kei te haere tonu hoki ngā rangahau hei aro atu ki ngā wero o nāianei, pēnei i te whakaiti i te whakaaro pākiki me te whakapai ake i te haumarutanga raraunga.
Ā tōna wā, tera pea ka kite tātou i te whakamahinga whānui o tēnei hangarau i roto i ngā āhuatanga maha o te oranga o ia rā, mai i te whakahaere urunga i te wāhi mahi, ngā pūnaha utu, tae atu ki ngā taunekeneke me ngā taputapu atamai i te kāinga.
Whakamutunga
Kua tino hurihia ngā pūnaha CCTV hou e te hangarau tirotiro kanohi mā te whakanui ake i te whai huatanga me te whai huatanga o te aroturuki. Ahakoa kei te mau tonu ngā wero, kāore e taea te whakanui rawa i ngā painga o tēnei hangarau. Mā te haere tonu o ngā whanaketanga hangarau me te whakamahinga tika, ka taea e te tirotiro kanohi te noho hei taputapu tino whai hua hei waihanga i ngā taiao haumaru ake, whakamarie ake hoki mō te katoa.
