Distance mita pasi. Nzira dzekufambisa kuyera daro

Distance kuyerwa - chimwe chezvinhu zvinokosha mabasa ari geodesy. Pane nzira dzakasiyana kuyera daro uyewo vakawanda zviridzwa zvakagadzirirwa tiite mabasa aya. Saka, isu funga nyaya iyi zvizere.

Direct kure chipimo nzira

Kana kuti zvionekwe chinhambo kusvika chinhu pamusoro dzikarurama mutsetse uye nzvimbo inowanika chidzidzo, uchishandisa mudziyo yakadai nyore kuti kuyera nechekure sechinhu simbi tepi. Kureba - kubva gumi kusvika makumi maviri mamita. Asi rinogona kushandiswa tambo kana waya, pamwe nyora chena uye tsvuku maviri gumi mamita. Kana uchifanira kuyera curvilinear zvinhu vaishandisa akwegura uye anozivikanwa maviri mita yemapuranga vanokamura (vakati vapfuura) kana, sezvo ivo vanouti, "Kovylek". Dzimwe nguva zvakakodzera kuti rokutanga kuyerwa anofungidzirwa rwakatwasuka. It anoita izvi kuyera daro matanho (matanho maviri pakuverenga ari wakaenzana kukura nerwodzi kubvisa 10 kana 20 cm).

Kuyera madaro pasi ari kure

Kana yokuwana kuyerwa chinhu mudzinza kuona, asi pamberi sezvisingakundiki zvipingamupinyi, zvichiita zvisingabviri mbune chinhu (semuenzaniso munyanza, nzizi, marshes, hova, etc.) rakashandiswa kure chipimo kure kuona nzira, uye zvakawanda zvakananga nzira, kubva ipapo pane mhando dzakawanda:

1. High-zvakarurama kuyerwa.
2. Low kuitika kana anofungidzirwa zvokuyera.

Aimbova zvinosanganisira kuyerwa achishandisa anokosha mano, akadai Manyiminya chikuva Radhika, remagetsi kana yemagetsi telemeter, chiedza kana Laser chikuva Radhika, ultrasonic siyana Radhika. Chechipiri mhando zvinosanganisira kuyera nzira dzakadai kutarisana geometry. Pano uye kutsunga pedaro kubva chisina kutsetseka kukura zvinhu, uye kuvakwa akaenzana-angled zvokuridza, uye nzira yakananga serifs dzakawanda dzimwe geometric nzira. Funga dzimwe nzira mukuru-zvakarurama uye anofungidzirwa zvokuyera.

The Manyiminya kure mita

kuyerwa hwemabasa madaro kusvika pedyo millimeter chaiye tsika zvinodiwa Kazhinji. Pashure pezvose, hapana vashanyi, hapana njere rehondo haazorambi kutakura zvinonakisa uye inorema zvinhu. Kunyanya kushandiswa munguva nyanzvi panenge pachivakwa uye basa rokuvaka. Anowanzoshandiswa aine mudziyo yakadaro kuti kuyera daro sechinhu Manyiminya rangefinder. It kunogona kugara uye shanduka parallax angled uye vanomiririra kamwene kune kwakajairika Theodolite.

Kuyerwa wakaumbwa kutwasuka uye zvido zvevanhu tambo netsvimbo ane chaiyo setup pamwero. Kururama dzakadaro kuyerwa rangefinder zvakakwana yakakwirira uye kukanganisa anogona kuwana kukosha 1: 2000. Range chipimo muduku uye yaiva chete pakati 20 uye kusvika 200-300 mamita.

Remagetsi uye Laser rangefinder

The remagetsi kure mita ndohwaJehovha inonzi zvechivhurumukira mhando mano, rakarurama kuyerwa ichaongororwa uye avhareji kukanganisa kuva pakati 1,2 uye 2 metres. Asi mano aya vane guru paanopfuura zvavo Manyiminya dzomuzana, sezvo rakanakira kuziva daro pakati zvinofamba zvinhu. Distance zvidzidzo vangava dzaona sezvo mamita uye makiromita, saka ivo inowanzoshandiswa pakuita zvemuchadenga.

Kana Laser rangefinder, rakagadzirirwa kuyera madaro havasi guru chaizvo, ane kumusoro zvakarurama uye zviduku. Izvi ndezvechokwadi kunyanya ano inotakurika Laser tambo tepi. mano aya uyere daro zvinhu ari chinhambwe 20-30 metres uye anosvika 200 metres, ane kukanganisa asingapfuuri 2-2.5 mm pakureba.

ultrasonic Distance Measurer

Ichi chimwe chezvinhu nyore uye mushandisi-ushamwari namano. Zviri nyore uye nyore ichishanda uye rinoreva zano kuti anogona kuyera chisina kutsetseka Coordonatele yacho uye vachiravana akapiwa pfungwa pamusoro mamiriro enzvimbo. Kunyange zvakadaro, kunze pachena zvazvakanakira zvaanazvo nezvayakaipira. Chekutanga, nekuti duku zvakawanda kure tambo vezvikwata mune midziyo iyi inogona dzaona chete masendimita uye metres - uye kubva 0.3 20 mamita. Uyewo, nokuyerwa yakarurama anogona zvishoma kushandurwa, sezvo okuteerera hutachiwana nokukurumidza kunoenderana arambe achirema ari svikiro, sezvazvakanyorwa anozivikanwa, haagoni kuva kuramba. Zvisinei, mudziyo uyu akakwana kuti kuyerwa kutsanya duku kuti haadi dzakakwirira nemazvo.

Geometric nzira nokuti kuyera madaro ne ziso

Kumusoro nayo nyanzvi nzira kuyera marefu. Uye zvokuita, kana ruoko iri kure hapana chaicho mita? Pano anouya kuzobatsira geometry. Somuenzaniso, kuyera upamhi mvura mhinganidzo, zvinokwanisika kuvaka pamusoro wayo pamahombekombe maviri equilateral zvokuridza zvakanaka, sezvinoratidzwa chati.

Panyaya iyi, iyo AF rwizi upamhi akaenzana DE-BF pamakona vanogona swatanudza pamwe kambasi mativi mapepa uye kunyange matavi fanana akayambuka. Pano, nezvinetso vasimuke.

Kunyange zvichibvira kuti kuyera chinhambo kusvika kupfura kubudikidza chipingamupinyi, uchishandisa geometric nzira uyewo zvakananga serifs rokuvaka rworudyi, triangle pamwe vertex pamusoro chipfuro uye kupatsanura kuva maviri ane mativi. Pane nzira dzokuziva upamhi chipingamupinyi vachishandisa nyore chipasa uswa kana shinda, kana nzira yokubatsira akaisa thumbs ...

Zvakakodzera kufunga nzira iyi muudzame, sezvo nyore. Pakatarisana mechidziro anosarudzwa kusiyirira chinhu (kuva nechokwadi kuziva anofungidzirwa kukwirira kwayo), ziso rimwe akavhara uye vakasarudzwa chinhu anonyengetedzwa akamutswa thumbs ruoko. Zvadaro, pasina vachisimudza munwe wako, pedyo akazaruka ziso wovhura Akanyatsovharwa. Finger anotendeuka chokuita wasarudza chinhu inodedera kurutivi. Zvichienderana nokukosha kukwirira nyaya, sei metres dzakawanda pasi nomunwe kwakaita nemaziso. kure Izvi kane gumi, uye mugumisiro ndiye fungidzira kufara mechidziro. Panyaya iyi, munhu pachake rinooneka sezvo stereophotogramrnetrical kure mita.

Geometric kure kuyera nzira dzakawanda. Waizoita taurira pamusoro nomumwe zvakadzama, zvichatora kutora nguva yakawanda. Asi ivo vose vari anofungidzirwa uye vari chete akakodzera ezvinhu umo kunyatsoyera vane zviridzwa hazvibviri.
