Pehea te Mahi a Laser Ranging

E ai ki te kaupapa matua, e rua nga momo tikanga laser rangi: te wa-o-rere (TOF) me te kore-wa-rere.He taiaho pupuhi me te taiaho-a-waa e rere ana i te wa-a-rererangi.

He tikanga ine ine i whakamahia tuatahi i roto i te waahi ruri me te mapi ma te hangarau laser.Na te mea he iti te koki rerekee laser, he poto rawa te roanga o te putere laser, he tino nui te mana inamata, na reira ka taea te whakatutuki i te awhe tino roa.I te nuinga o te waa, kaore i te whakamahia te whaainga mahi tahi, engari ko te whakaata o te tohu marama e te ine ine ka whakamahia hei ine i te tawhiti.

Ko te kaupapa o te tikanga o te kowhatu pupuhi kua tino marama.Ka peia e te karaka auau teitei te porotiti ki te tatau i te wa i waenga i te tuku me te tango i nga pini, na te mea ka iti ake te wa o te karaka tatau i te wa i waenga i te tuku me te tango i nga pini kia tika ai te tika, no reira he pai tenei tikanga awheawhe mo te roa- inenga tawhiti.

He iti te koki tukunga o te laser pulsed, he tino aro te kaha ki te mokowhiti, a he nui te mana inamata.Ma te whakamahi i enei ahuatanga, ka taea te hanga i nga momo awheawhe laser reo me te tawhiti tawhiti, lidars, aha atu.I tenei wa, kei te whakamahia whanuitia te laser pulsed i roto i te ine topographic me te geomorphological, te tirotiro whenua, te ine hanga miihini, te ine teitei o te waka rererangi, te aukati i nga arai waka me te arorau, te ine tawhiti o te ahumahi me etahi atu waahanga hangarau.

Ko te waahanga taiaho ko te whakamahi i te auau o te roopu reo irirangi ki te whakarereke i te kaha o te kurupae laser me te ine i te whakaroa o te wahanga i hangaia e te rama whakarereke e hoki whakamuri ana ki te raina ine, katahi ka huri i te tawhiti e tohuhia ana e te whakaroa o te wahanga kia rite ki ki te roangaru o te marama kua whakarereketia.Arā, ko te wā e tika ana mo te marama ki te hoki whakamuri i te raina ruri ka inehia ma te tikanga autaki.Kei te nuinga o te wa e whakamahia ana te waahanga laser i roto i te waahanga o te tino tika.Na tona tino tika, te tikanga i roto i te raupapa o te mitamano, kia pai ai te whakaata i te tohu me te whakawhāiti i te ine ine ki te waahi motuhake e rite ana ki te tika o te taputapu, ka whakauruhia tenei taputapu awheawhe ki te whakaata e kiia nei ko te whaainga mahi tahi.pereti.

I te nuinga o te wa ka pai te awhe taiaho mo te inenga poto me te tawhiti waenga, a ka eke te tika o te ine ki te mitamano.He tikanga me te tino tika o te reanga i naianei.Ko te waahanga ko te whakarereke i te kaha marama o te ngaru marama e tukuna ana me te tohu whakahuri, me te ine autaki i te waa ma te ine i te rereketanga o te waahanga, he iti ake te uaua i te ine tika i te waa haere-a-huri.
