Te Tarakona me te Pūnaha Whakatere Pai rawa atu
Kua tino tere haere te whanaketanga o ngā waka rererangi iti i roto i te tekau tau kua pahure ake nei. Ahakoa i mua ko ngā waka rererangi iti he rite ki ngā mahi whakangahau me te whakaahua noa, kua riro inaianei hei taputapu ngaio i roto i ngā momo mara: te mahere whenua, te tirotiro hanganga, te ahuwhenua tika, te haumarutanga, tae atu ki ngā mahi rapu me te whakaora. Haunga ngā āheinga rere pumau me te tika, ko tētahi āhuatanga e tino whakatau ana i te kounga o te waka rererangi iti: ko tana pūnaha whakatere. Ko ngā waka rererangi iti me ngā pūnaha whakatere pai rawa atu ehara i te mea ka taea anake te rere "whai i te rakau hari," engari ka taea hoki te mārama me te haumaru ki te tūranga, te ahunga, te huarahi, ngā arai, me ngā āhuatanga taiao.
E matapakihia ana i roto i tēnei tuhinga ngā āhuatanga e "pai rawa atu" ai te pūnaha whakatere waka rererangi kore, te hangarau e whakamahia ana, ngā āhuatanga hei whakaaroaro i mua i te hoko, me ngā tauira o tōna whakamahinga i roto i ngā āhuatanga o te ao tūroa.
He aha te hiranga o te pūnaha whakatere?
Ko te pūnaha whakatere te "roro" e whakatau ana me pēhea te mōhio o te waka rererangi ki tōna tūranga, ki hea e tika ana kia haere, me pēhea hoki e pupuri ai i te pumau. Mēnā he pai te whakatere, ka taea e te waka rererangi te:
1. Rere mārire ake i ngā hau kaha, i ngā wāhi ngoikore rānei ngā tohu GPS.
2. Kia tino tika te tae atu ki te wāhi e haerea ana i roto i ngā mahere whenua, i ngā mahi tirotiro rānei.
3. Āraia ngā tukinga mā te kimi arai.
4. Hoki atu me te haumaru ina iti te pākahiko, ina ngaro rānei te tohu (Hoki-ki-te-Kāinga).
5. Whakahaerehia ngā misioni aunoa pērā i te tohu ara, te whai-i-a-koe, te porowhita, te mahere whatunga rānei.
Mō ngā kaiwhakamahi ngaio, ehara te whakatere i te āhuatanga tāpiri noa iho. Koinei te tūāpapa e whakatau ana i te kounga o ngā raraunga, te haumaru mahi, me te whai huatanga o te mahi.
Ngā Wāhanga Matua o te Pūnaha Whakatere Drone
Ko ngā pūnaha whakatere waka rererangi hou e whakakotahi ana i ngā pūoko me ngā rauropi maha (he whakakotahitanga pūoko). Mā te whānui ake o ngā pūoko, ka ngāwari ake te urutau o te waka rererangi ki ngā āhuatanga o te mara.
1. GNSS (GPS me ngā Hoa)
Ko te nuinga o ngā waka rererangi korekore e whakamahi ana i te GNSS (Global Navigation Satellite System), ehara i te GPS anake. Kei roto i ngā pūnaha GNSS:
– GPS (Te Hononga o Amerika)
– GLONASS (Rūhia)
– Galileo (Te Kotahitanga o Ūropi)
– BeiDou (Haina)
Ko ngā waka rererangi kore-rangi me ngā pūnaha whakatere pai rawa atu ka tautoko i ngā whetū maha kia noho tika tonu i ngā wāhi "uaua" pērā i te taha o ngā whare teitei, ngā awaawa, ngā ngahere rānei.
2. IMU (Wāhanga Ine Ā-Inertia)
Kei roto i te IMU he gyroscope me he accelerometer hei ine i te hurihanga me te whakaterenga. Ka āwhina te IMU i te drone kia mau tonu te pumau, inā koa ka ngoikore te tohu GNSS. He kounga teitei te IMU o te drone pai, ā, he pūnaha whakatikatika pakari hei ārai i te nekeneke.
3. Kāpehu (Mēnetomite)
Mā te kāpehu ka āwhina i te waka rererangi iti ki te whakatau i tōna ahunga. He mea nui tēnei mō te whakatere huarahi, te hoki ki te kāinga, me ngā nekehanga tika. Heoi, he tairongo ngā kāpehu ki ngā raruraru aukume (hei tauira, ngā mea whakarewa nui, ngā taura hiko, ngā hanganga whare rānei). Ko ngā waka rererangi iti ngaio he pūnaha kite raruraru kāpehu me ngā pūnaha whakatūpato wawe.
4. Paemita me te Ārahimita
Hei pupuri i te teitei pumau, ka whakamahia e ngā waka rererangi korere he paeromita. Ka whakamahia hoki e ētahi waka rererangi korere ētahi atu pūoko pērā i te ine teitei taiaho, te ToF rānei (Time of Flight) hei whakapai ake i te tika i ngā teitei iti.
5. Te Tūnga Tirohanga me te Rere Whatu
Ina uaua te GPS (hei tauira, i roto i te whare, i raro rānei i te tuanui o te rākau), ka taea e te waka rererangi te whakamahi i tana kāmera ki raro me ngā pūoko rere whatu hei "pānui" i ngā nekehanga o te mata. Mā tēnei ka taea e te waka rererangi te rere mārire ahakoa kāore he GPS.
6. Pūnaha Kite Ārai (Te Karo Ārai)
Koinei te rerekētanga nui i waenga i te waka rererangi korere noa me tētahi he matatau te whakatere. Ko ngā pūoko ārai arai ka taea te:
– Kāmera tirohanga orooro, tirohanga maha-aronga rānei
– Pūoko pūoko whero
– LiDAR (i runga i ngā waka rererangi ā-umanga)
Mā te whakamahi i ēnei pūoko, ka taea e te waka rererangi te kite i ngā mea kei mua, kei muri, kei te taha, kei runga, kei raro iho hoki—kātahi ka whakaroa aunoa, ka aukati, ka karo rānei i a rātou.
Ngā Hangarau Whakatere Matatau: RTK me PPK
Mō te mahere me te ruri whenua tino tika, kāore e ranea te GNSS paerewa. Koinei te wāhi e whai wāhi mai ai ngā hangarau RTK (Real-Time Kinematic) me te PPK (Post-Processed Kinematic).
– Ka whakapai ake te RTK i te tika o te tūranga ki te taumata henimita i te wā tūturu mā te awhina o te teihana turanga, te whatunga whakatika rānei.
– Ka whakatikahia e PPK ngā raraunga tūnga i muri i te rerenga, he mea whai hua ina kore e pumau te hononga whakatika wā-tūturu.
Ko ngā waka rererangi kore-rangi me te whakatere pai rawa atu mō te mahi whenua-ā-rohe ka tautoko i te RTK/PPK, kia tika ake ai ngā hua o te mapi, kia iti ake ai te hiahia mō ngā pūwāhi whakahaere whenua.
