Hangarau Whakamōhio Reo i roto i te CCTV Hou
I ngā tau tata nei, kua nui atu ngā pūnaha CCTV (Pouaka Whakaata Porowhita Kati) i te noho hei "pūoro hopu" noa iho. Nā ngā whanaketanga o te matauranga horihori (AI), te rorohiko taha, me te whakaurunga o ngā taputapu IoT kua taea e ngā pūnaha CCTV hou te tātari i ngā kaupapa i te wā tonu. Ko tētahi auahatanga e piki haere ana te aro ko te hangarau mōhio reo me te tātari oro i roto i te CCTV. Mā ēnei āheinga, ka taea e ngā pūnaha CCTV te "rongo" ki ō rātou taiao, te mōhio ki ngā tauira oro motuhake, te tautuhi i te kōrero, me te āwhina ki te tere ake i ngā urupare haumarutanga.
Mai i te Hopu Ataata ki ngā Pūnaha Aroturuki Maha-Waea
I ngā wā o mua, ko te arotahi a te CCTV ki te tirotiro ā-kanohi: te hopu whakaahua, te kite i ngā nekehanga , me te tiaki i ngā taunakitanga. Heoi, he maha ngā aituā haumarutanga ka tīmatahia, ka tohuhia rānei e te oro—he karanga āwhina, he tangi o te karāhe pakaru, he pū pupuhi, he whakaoho, he tautohetohe rānei. Nō reira, kei te piki haere te hiranga o te huarahi maha-ara (te whakakotahi i te ataata me te oro). Mā te hangarau mōhio reo i roto i te CCTV hou ka taea e te taputapu te hopu tohu oro mā te hopuoro, te tukatuka, kātahi ka huri hei mōhiohio mahi pēnei i ngā whakamōhiotanga, ngā whakaoho whakaoho, te tohu rānei i ngā kiriata.
He aha te Whakamōhio Reo i roto i te CCTV?
He whānui te whakamahinga o te kupu "whakamōhio reo", engari i roto i te horopaki o te CCTV he maha ngā āheinga rerekē:
1. Te kimi kaupapa e hangai ana ki te oro
Ka mōhio te pūnaha ki ētahi momo oro, pērā i te pakaru o te karāhe, te pahūtanga, te pupuhi pū, te whakaoho auahi, te tangi, te hamama rānei.
2. Te mōhio ki te kōrero (kōrero-ki-te-kuputuhi)
Ka hurihia te oro kōrerorero hei tuhinga, kia taea ai e ngā kaiwhakahaere te rapu kupumatua motuhake, te arotake rānei i te horopaki o tētahi huihuinga kia tere ake.
3. Te tautuhi/te manatoko i te kaikorero
Ka ngana te pūnaha ki te tautuhi ko wai kei te kōrero i runga i ngā āhuatanga o te reo. He uaua ake tēnei, he tairongo ake hoki, ā, me whai raraunga tohutoro tika i te nuinga o te wā.
4. Tātari kare ā-roto, tātari ahotea rānei (tātari ahotea reo/kare ā-roto)
Ka aromatawaihia e te pūnaha ngā tohu pēnei i te reo, te oro, me te tere hei aromatawai i ngā āhua kare ā-roto (riri, mataku, pukuriri). Me tino tupato tēnei āhuatanga nā te mea he tūponotanga o te whakaaro pākiki.
I te parae, ko te CCTV e whakamahia whānuitia ana i roto i te haumarutanga ko te kimi i ngā huihuinga oro me te tātari oro ngāwari, nā te mea he whai hua ake, he māmā ake hoki te whakatinana me te taumata pumau o te tika.
He Tirohanga Poto ki te Mahi a tēnei Hangarau
I roto i te hangarau, ko te tukanga mōhio reo i runga i te CCTV hou ka whai i ngā wāhanga e whai ake nei:
1. Te hopu oro
Ka hopukina te oro e te hopuoro ā-roto, e te hopuoro o waho rānei o te kāmera. He nui te pānga o te kounga o te hopuoro ki ngā hua, inā koa i ngā taiao haruru.
2. Te tukatuka-mua
Ka mahi te pūnaha i te whakaiti haruru, te whakakore i te ako, te whakataurite i te oro, me te wehe. tohu hei whakaiti i te pokanoa.
3. Te tango āhuatanga
Ka hurihia te oro hei whakaaturanga tau—hei tauira, he whānuitanga auau, he āhuatanga rānei pēnei i te MFCC (Mel-Frequency Cepstral Coefficients)—kia māmā ake ai te mārama mō ngā tauira AI.
4. Whakarōpūtanga, tuhi rānei
Ka whakarōpūhia e te ako mīhini, e ngā tauira ako hōhonu rānei ngā oro (te pakaru o te karāhe, te hamama, me ētahi atu) ka tuhia rānei te kōrero ki roto i te tuhinga.
5. Ngā mahi pūnaha
Ka whakaohohia e ngā hua tātari he whakamōhiotanga ki te taupānga, ka tangihia he haona, ka tukuna he wāhanga o te rekoata, ka tohua te rārangi wā rekoata, ka whakahohe rānei i ētahi atu tukanga haumarutanga.
I ngā pūnaha hou, ka taea te tukatuka i ētahi mahi i runga i te pūrere kāmera (taha) hei whakaiti i te whakaroa, ko ētahi atu wāhanga ia ka mahia i runga i te tūmau/NVR, i te kapua rānei hei tātaritanga taumaha ake.
Te Whakaurunga ki Ētahi Atu Āhuatanga CCTV Hou
He pai ake te hangarau oro ina whakauruhia ki te tātari ataata. Hei tauira:
– Ka whakaoho aunoa te oro i te rapu ataata: Ina kitea he hamama, ka tohua tonutia e te pūnaha te wāhanga ataata ka whakanuia ngā wāhi e mahi ana te tangata.
– Tirotiro-whakawhiti: Mēnā ka kitea te haruru o te pakaru o te karāhe, ka tirohia e te pūnaha mēnā he nekehanga, he huringa tirohanga rānei i te matapihi.
– Te whakaiti i te whakaoho rūpahu: Ka taea te tātari i ngā whakaoho nekehanga i puta mai i ngā kararehe mēnā kāore he tohu o ngā oro tangata, o ngā oro rānei o tētahi huihuinga motuhake.
– Ororongo rua-ara: Ka taea e te kaiwhakahaere te kōrero ki te kaikorero kāmera hei whakatūpato (“Kei raro i te tirotirohanga tēnei rohe…”) ka taea rānei te tohutohu i te hunga ki te wāhi i pā ai te aituā.
Ngā Painga Matua o te Whakamōhio Reo i runga i te CCTV
1. Te urupare tere ake
Kāore ētahi o ngā aituā e kitea mārama ana i te kāmera, inā koa i ngā wāhi pōuri, i ngā koki kua hunaia, i te wā rānei kāore i te tika te tohu o te kāmera. He tohu wawe te oro hei akiaki i te mahi tonu.
2. He rapunga rekoata whai hua ake
Mena kua tuhia, kua tapaina rānei te oro, ka taea e ngā kaiwhakahaere te rapu i ngā kaupapa mā te kupumatua, mā te momo oro rānei, me te kore e mātaki i ngā haora o ngā rekoata.
3. Te whakanui ake i te haumaru
Mā te kite i ngā reo hamama, tautohetohe, pukuriri rānei, ka āwhina i te ārai i te pikinga ake o te riri i mua i te tomuri rawa, inā koa i ngā kura, i ngā hōhipera, i ngā waka a te iwi, i ngā wāhi waka rānei.
4. Uara tāpiri mō te aroturuki pakihi
I roto i ngā ratonga hokohoko me ngā ratonga tūmatanui, ka taea e te ororongo te āwhina ki te kimi i ngā pakanga, te aroturuki i ngā rarangi, te tere ake rānei te urupare a ngā kaimahi ki ngā aituā.
Ngā Wero me ngā Here i te Marae
Ahakoa he mea whai hua, kāore tēnei hangarau i te tino tika. Ko ētahi o ngā wero nui ko:
– Haruru taiao: Ka taea e ngā huarahi tere, ngā mīhini wheketere, ngā puoro, ngā mano tini rānei te whakararuraru i te tika.
– Te tawhiti me te tūnga o te hopuoro: Ko te tawhiti atu i te pūtake oro, ko te iti ake o te tūponotanga ka angitu te mohio.
– Ngā rerekētanga o te reo me ngā reo ā-iwi: Me whai tauira reo e tika ana mō te whakawhitiwhiti kōrero. I roto i ngā taiao reo maha, ka heke te tika.
– Ngā hua pai teka me ngā hua kino teka: Ka rite te tangi o tētahi mea e hinga ana ki te pupuhi pū i raro i ētahi āhuatanga. Me whirihora me te whakamātautau i te pūnaha kia rite ki te horopaki o te tauwāhi.
– Ngā herenga taputapu: Ko te tukatuka ororongo wā-tūturu me nui ake te whakaterenga CPU/AI, te whānui o te hononga, me te rokiroki mēnā ka hopukina tonutia te ororongo.
Nō reira, ko te whakatinanatanga pai ko te whakatikatika whirihoranga, te whakamātautau i ngā horopaki o te ao tūturu, me ngā huinga pūoko (oro + ataata + pūoko tāpiri).
Ngā Take Tūmataiti me te Whakatutukitanga
He tino tairongo ngā raraunga oro. Tērā pea kei roto i ngā kōrero kua hopukina ngā mōhiohio whaiaro, ngā mea ngaro pakihi, ngā raraunga tuakiri rānei. Nō reira, me whai whakaaro ki te whakamahinga o te mōhiotanga reo i runga i te CCTV:
– Pūtake ture me ngā whakaritenga whakahaere: Ngā kaupapa here tūmataiti ā-rohe, ngā ture mahi, me ngā whakaritenga tiaki raraunga.
– Pānui mārama: He mea nui te whakamōhio kei te hopukina te rohe i ngā oro me ngā ataata (ngā tohu).
– Ngā here urunga: Ko ngā rōpū whai mana anake ka taea te uru atu ki ngā tuhinga; whakamahia ngā rangitaki arotake.
– Te whakamunatanga me te haumarutanga raraunga: Te whakamunatanga i te wā e rokiroki ana me te tuku, tae atu ki ngā whakahōu pūmanawa auau.
– Te pupuri raraunga: Whakatauhia te wā pupuri oro/ataata kia rite ki ō hiahia me ngā kaupapa here ture.
– Te whakaiti i ngā raraunga: I ngā wā katoa e taea ai, rongoatia ngā "metadata o ngā huihuinga" (hei tauira, te tapanga "karaehe pakaru") me te kore e rongoa i ngā oro mata, hei whakaiti i te mōrearea.
Ko te huarahi "tūmataitinga mā te hoahoa" he mea nui kia whai hua ai tēnei hangarau me te kore e takahi i ngā mana tūmataiti.
Ngā Tauira o te Whakamahinga i roto i ngā Rāngai Rerekē
– Whare noho me ngā whare noho: Kitea ngā hamama, ngā whakaoho, ngā nganatanga uruwhenua rānei hei whakaoho i ngā whakamōhiotanga ki ngā kainoho me ngā āpiha haumarutanga.
– Ngā pokapū hokohoko me ngā pokapū hokohoko: Tāutuhia ngā pakanga, ngā raruraru, ngā āhuatanga ohorere rānei e hiahia ana kia tere te urupare.
– Wheketere me te whare putunga: He tangi whakaoho mīhini rerekē, he tohu mōrearea rānei, me te kāmera hei whakarite i te haumaru mahi.
– Ngā kura me ngā puni: Te kimi i ngā hamama, i ngā pakanga rānei, me te aroturuki i ngā ara raro me ngā marae.
– Te kawe waka a te iwi: He haruru ngā teihana, ngā taunga waka, me ngā taunga, engari he pai tonu te whakamahi i ngā tātaritanga oro hei kite i ngā huihuinga tino kino (ngā hamama mataku, ngā pahūtanga).
Te Anamata: Mai i te Kimi Reo ki te "Mārama ki te Horopaki"
Ā tōna wā, ka neke atu te CCTV me te mōhio ki te kōrero i te "kitenga tauira" ki te "mārama horopaki." Ko te tikanga, kāore te pūnaha e mōhio noa ki ngā oro motuhake engari ka whakauru hoki i ngā horopaki tirohanga, te tauwāhi, te wā, me ngā tauira hītori hei whakarato i ngā aromatawai mōrearea tika ake. Ka kaha ake hoki te Edge AI, ka taea ai te tukatuka tika i runga i te kāmera, ka whakaiti i te whakawhirinaki ki te kapua, ka tere ake hoki ngā wā urupare.
Heoi, ko te matatau ake o te hangarau, ko te nui ake o te kawenga o ngā kaiwhakahaere. Me haere tahi te haumarutanga ipurangi, ngā kaupapa here tūmataiti, me te māramatanga o te whakamahinga hei pupuri i te whakawhirinaki a te marea.
Te Katinga
Ka kawea mai e te hangarau mōhio reo i roto i ngā pūnaha CCTV hou tētahi taha hou ki ngā pūnaha haumarutanga: te kaha ki te kite i ngā kaupapa ehara i te mea mā te mea e kitea ana, engari mā te mea hoki e rangona ana. Mā te whakatinanatanga tika—te aro ki te kounga o te taputapu, te whirihoranga, te whakaurunga ataata, me te tutuki i ngā whakaritenga tūmataiti—ka taea e ngā tātaritanga oro te whakapai ake i ngā wā urupare, te whakaiti i te taumahatanga o te aroturuki ā-ringa, me te whakapakari i te haumaru i roto i ngā momo taiao. Ehara te CCTV o ēnei rā i te "kanohi" tirotiro noa iho, engari kei te huri hei pūnaha atamai me te māramatanga whānui ki te āhuatanga.
