Distance mita pansi. Njira kuyeza mtunda

Distance muyeso - mmodzi wa ntchito zofunika mu geodesy. Pali njira zosiyanasiyana za kuyeza mtunda komanso ambiri zida lakonzedwa kuti agwire ntchito zimenezi. Choncho, ife lingalirani mwatsatanetsatane.

Direct mtunda njira muyeso

Ngati chofunika kudziwa kutalika kwa chinthu pa mzere molunjika ndi madera ndi yochitira phunziro pogwiritsa ntchito ngati chipangizo wosavuta kuyeza mtunda monga tepi zitsulo. M'litali - kuchokera mamita khumi ndi ziwiri. Koma zikhoza kugwiritsidwa ntchito chingwe kapena waya, ndi kulemba woyera ndi wofiira mamita awiri khumi. Pamene mukufuna kuyeza zinthu curvilinear ntchito akale ndi odziwika ziwiri mita matabwa dividers (fathoms) kapena, ngati iwo amadzitcha izo, "Kovylek". Nthawi zina m'pofunika kuti kuyambirira miyezo pafupifupi molondola. Iwo amachita zimenezi ndi kuyeza masitepe mtunda (masitepe awiri kuwerengetsa wofanana kukula chingwe opanda 10 kapena 20 cm).

Kuyeza mtunda pansi chosonyeza

Pa nkhani ya kupeza muyeso chinthu mu mzere wa pamaso, koma pamaso mavuto akuluakulu, kupangitsa mwayi zosatheka mwachindunji kuti chinthu (mwachitsanzo nyanja, mitsinje, m'madambo, zigwembe, etc.) ntchito muyeso mtunda kutali zithunzi njira, ndipo makamaka njira, popeza pali mitundu ingapo:

1. Mkulu-mwatsatanetsatane miyezo.
2. Low panopa kapena pafupifupi miyezo.

Zoyambazo monga muyeso mwa zipangizo zapadera monga finders kuwala osiyanasiyana, mu atomu kapena pakompyuta telemeter, kuwala kapena laser finders osiyanasiyana, akupanga osiyanasiyana finders. Mtundu wachiwiri zikuphatikizapo kuyeza njira monga Masamu zithunzi. Apa ndi mtima wa mtunda kuchokera kukula okhota wa zinthu, ndi kumanga ndi Triangles ofanana-angled, ndi njira yolunjika serifs ambiri njira zina zojambula. Taonani njira zina za mkulu-yolinganizika ndi miyezo idzatha.

Mtunda mita kuwala

Chotero miyezo ya kutalika kwa millimeter yapafupi kuchita yachibadwa zofunika infrequently. Ndipotu palibe alendo, palibe nzeru asilikali sadzakhala kunyamula akukhudzidwira ndi katundu zinthu. Makamaka iwo ntchito pa yoyeza akatswiri ndi ntchitoyo. Kambirimbiri ndi chipangizo chotero kuona patali ngati rangefinder kuwala. Kungakhale onse zonse ndi variable parallax ngodya ndi kuwayimilira nozzle kuti theodolite ochiritsira.

Miyezo anapangidwa kwa ofukula ndi yopingasa chingwe ndodo ndi dongosolo mlingo wapadera. Yolondola miyezo ngati rangefinder mokwanira mkulu ndi zolakwa kufika kufunika 1: 2000. Osiyanasiyana muyeso ang'ono ndi chimachititsa yekha pakati pa 20 mpaka 200-300 mamita.

Mu atomu ndi laser rangefinder

The mu atomu mtunda mita wa otchedwa zipangizo mtundu mopupuluma, yolondola muyeso wa imatengedwa ndi zolakwa pafupifupi akhoza kukhala pakati pa 1.2 ndi 2 mamita. Koma zipangizozi ndi mwayi waukulu anzawo kuwala, monga abwino kudziŵa mtunda pakati pa zinthu kusunthira. mayunitsi Distance iwo akhoza kuchita masamu ngati mamita ndi makilomita, choncho amachita ntchito pochita mlengalenga.

Koma laser rangefinder Chinapangidwa kuyeza kutalika si lalikulu kwambiri, ali mkulu molondola ndi yaying'ono kwambiri. Izi ndi zoona makamaka kwa kunyamula ano laser chingwe tepi. zipangizozi kuyeza mtunda zinthu pa mtunda wa mamita 20-30 mpaka mamita 200, ndi zolakwa za osapitirira 2-2.5 mm m'litali.

akupanga Distance Measurer

Ichi ndi chimodzi mwa zida ambiri kumodzi ndi wosuta-wochezeka. N'zosavuta ndi losavuta ntchito ndipo amatanthauza chipangizo kuti angathe kuyeza ndondomeko okhota a m'derali mfundo payokha oti alili. Komabe, popanda ubwino zoonekeratu ali ndi kuipa. Choyamba, chifukwa cha osiyanasiyana ka mtunda mayunitsi chingwe mu zida izi zikhoza kukhala masamu okha mainchesi ndi mamita - ndi ku mamita 0,3 ndi 20. Komanso, yolondola muyeso akhoza pang'ono anasintha, kuyambira zomvetsera HIV liwiro zimadalira osalimba a sing'anga, monga amadziwika, sangakhale zonse. Komabe, chipangizo ichi ndi wangwiro miyezo kudya kakang'ono kamene musati amafuna mkulu mwatsatanetsatane.

njira zojambula kuona mtunda diso

Pamwamba anachitira ndi njira akatswiri kuyeza mtunda. Ndipo chochita, pamene dzanja palibe mtunda yeniyeni mita? Apa pakubwera kuthandiza Masamu. Mwachitsanzo, kuyeza m'lifupi chotchinga madzi, n'zotheka kumanga pa gombe awiri Triangles ake equilateral bwino, monga momwe taperekachi.

Mu nkhani iyi, AF mtsinje m'lifupi ndi wofanana kumathandiza kupeza ngodya zabwino DE-BF akhoza agwirizane ndi kampasi, mapepala lalikulu la pepala ndipo ngakhale ndi nthambi zofanana anawoloka. Apa, mavuto ayenera uka.

Komabe n'zotheka kuyeza mtunda chandamale kudzera chopinga, pogwiritsa ntchito njira zojambula komanso serifs mwachindunji kumanga kansalu bwino ndi vertex pa chandamale n'kuduladula mu awiri amaganiza. Pali njira kudziwa m'lifupi akutilola ntchito tsamba wamba udzu kapena chingwe, kapena njira kuthandiza anakoloweka chala ...

Ndi bwino kuganizira njira imeneyi mwatsatanetsatane, kuyambira ndi yophweka. Pa mbali ina ya akutilola anasankha loonetsa chinthu (onetsetsani kudziwa pafupifupi kutalika kwake), diso limodzi anatseka ndipo anasankha item ndi chinachititsa anakweza chala dzanja. Kenako, popanda kutukula chala chanu, pafupi kutsegula maso ndi kutsegula chatsekedwa. Chala akutembenukira poyerekezera ndi chinthu anasankha anawamvera pambali. Zochokera pafupifupi kutalika kwa nkhaniyi, za momwe mamita ambiri kuuzenga kuti chala kwapita zowoneka. Mtunda Izi kuchulukitsa ndi khumi, ndipo zotsatira zake ndi zoyerekeza m'lifupi akutilola. Pankhaniyi, munthuyo zikuoneka ngati stereophotogramrnetrical mtunda mita.

Zojambula mtunda kuyeza njira zambiri. Kodi inu mungandiuze za aliyense mwatsatanetsatane, kudzatenga nthawi yambiri. Koma iwo onse ali pafupifupi ndi yabwino kokha kwa zinthu kumene yeniyeni muyeso ndi zida n'zosatheka.
