Ungazikhetha Kanjani Amasu wokulinganisa asuselwa ekubonisweni

I-Laser RangeFinders, i-Lidars, namanye amadivaysi asetshenziswa kabanzi kwizimboni zanamuhla, ukucwaninga, ukushayela okuzimele, kanye ne-elekthronikhi yabathengi. Kodwa-ke, abasebenzisi abaningi babona ukuphambuka okubalulekile kokukalwa lapho kusebenza ensimini, ikakhulukazi lapho ubhekana nezinto zemibala ehlukene noma izinto zokwakha. Imbangela yaleli phutha imvamisa ihlobene kakhulu nokuvezwa kwelitshe. Le ndatshana izophenduka umthelela wokuthambekela kokulinganisa ibanga futhi inikeze amasu asebenzayo ekukhetheni okuqondiwe.

1. Kuyini ukuvelela futhi kungani kuthinta ukukalwa kwebanga?

Ukuthenjwa kubhekisele emandleni okuthola amandla okukhanya okusobala ukukhombisa ukukhanya kwesigameko, okuvame ukuvezwa njengephesenti (isib. Udonga olumhlophe lunombukiso wabantu abacishe babe ngu-80%, kuyilapho irabha elimnyama linama-5% kuphela). Amadivayisi wokulinganisa we-Laser anquma ibanga ngokubala umehluko wesikhathi phakathi kokukhanya okukhishwe futhi kuboniswe ukukhanya (kusetshenziswa umgomo we-time-of-fle flight). Uma ukuthathwa kwelitshe kuphansi kakhulu, kungaholela ku:

- Amandla wesiginali abuthakathaka: Uma ukukhanya okubonisiwe kubuthakathaka kakhulu, idivaysi ayikwazi ukuthwebula isinali elivumelekile.

- Ukwanda kwephutha lokulinganisa: ngokungenelela okuphezulu komsindo, ukunemba kuyancipha.

- Uhla lokulinganisa olufushaniwe: Ibanga eliphakeme elisebenzayo lingakwehla ngaphezu kwama-50%.

2. Ukuvezwa kokuqala kanye namasu okukhetha okuhlosiwe

Ngokusekelwe kwizici zezinto ezijwayelekile, amatshe ahlosiwe angahlukaniswa ezigabeni ezintathu ezilandelayo:

① okuhlosiwe okuhlosiwe okuphezulu (> 50%)

- Izinto ezijwayelekile: Izibuko zensimbi ezibunjiwe, izibuko, ubumba obumhlophe, ukhonkolo okhanyayo okhanyayo

- Izinzuzo: Ukubuyiselwa kwesiginali okuqinile, kufanelekile ibanga elide (ngaphezu kwama-500m) izilinganiso eziphezulu zokuqina

- Izimo Zokusebenza: Ukuhlola Ukwakhiwa, Ukuhlolwa komugqa wamandla, ukuskena kwe-Drone Terrain

- QAPHELA: Gwema indawo yesibuko engaholela ekubonisweni okucatshangelayo (okungadala ukuphathwa kabi).

② imigomo yokuvuselela okuphakathi nendawo (20% -50%)

- Izinto ezijwayelekile: izinkuni, imigwaqo ye-asphalt, izindonga ezimnyama zezitini, izitshalo eziluhlaza

- I-Countermeasure:

Nciphisa ibanga lokulinganisa (Kunconyelwe <200m).

Nika amandla imodi yokuzwela ephezulu yedivayisi.

Khetha indawo ye-matte (isib. Izinto ezifuywayo).

③ imigomo ephansi yokuzambisa (<20%)

- Izinto ezijwayelekile: irabha elimnyama, izinqwaba zamalahle, izindwangu ezimnyama, imizimba yamanzi

- Izingozi: Amasiginali angalahleka noma ahlupheke ngokugxuma amaphutha.

- Izisombululo:

Sebenzisa ithagethi ekhombisa i-retro (ekhombisa).

Lungisa i-Angle ye-Laser ngemuva kwe-45 ° (ukuze uthuthukise ukuboniswa okuhlukile).

Khetha amadivayisi asebenza kuma-wavelength angu-905nm noma ngo-1550nm (wokungena okungcono).

3. Amasu akhethekile wesimo

① Ukulinganiswa kwethagethi eqondisiwe (isib. Izimoto ezihambayo):

- Ibeka phambili amapuleti welayisense emoto (izindawo eziphakeme zokubonana) noma imizimba yemoto ekhanyayo ekhanyayo.

- Sebenzisa ubuchwepheshe bokuqashelwa kwe-echo obuningi (ukuhlunga imvula nokuphazanyiswa kwenkungu).

Ukwelashwa okuyinkimbinkimbi okuphezulu:

- Ngensimbi emnyama, faka izigqoko ze-matte (ezingathuthukisa umvuzo kuma-30%).

- Faka izihlungi ze-polaring phambi kwezindonga ze-Glass Curtain (ukucindezela okubonakalayo okucatshangelwe).

③ Isinxephezelo Sokuphazanyiswa Kwezemvelo:

- Nika amandla ama-algorithms angemuva angemuva wokucindezela kwezimo ezikhanyayo.

- Emvuleni noma eqhweni, sebenzisa ubuchwepheshe be-Pulse Stimel Modal (Pim).

4. Imihlahlandlela yemithi ye-Par Nameter Tuning

- Ukulungiswa kwamandla

- Ukwemukela i-Appere: Khulisa ububanzi belensi yokuthola (ngakho konke ukuphindaphindwa kabili, inzuzo yesiginali inyuka kane).

- Ukulungiselelwa komkhawulo

I-5

Izinhlelo ezilandelayo zokulinganisa ibanga lesizukulwane seziqala ukuhlanganisa:

- Ukulawulwa kwe-Adaptime (AGC): Ukulungiswa kwesikhathi sangempela kokuzwela kwe-PhotoDodetor.

- Ukuqashelwa Kwezinto Ezibonakalayo Ai algorithms: Ukuqondanisa izinhlobo zezinto ezibonakalayo kusetshenziswa izici ze-echo waveform.

- I-Multispectral Fusion: Ukuhlanganisa ukukhanya okubonakalayo kanye nedatha ekhanyiselwe yokwahlulela okuphelele.

Ukugcina

Ukukwazi kahle izici zokuthembisa kuyikhono eliyisisekelo lokwenza ngcono ukunemba kokukalwa. Ngokukhetha ngokwesayensi okukhethiwe kanye nokumisa amadivaysi kahle, ngisho nasezimweni eziphansi ze-Ultra-eziphansi (ngaphansi kuka-10%), ukunemba okulinganiswa kwezinga lama-millimeter. Njengoba ubuchwepheshe obunobuhlakani benxephezelo bukhula, izinhlelo zokulinganisa ezizayo zizoshintshana kakhulu ngokuthi "ngobuhlakani" ezindaweni eziyinkimbinkimbi. Kodwa-ke, ukuqonda izimiso eziyisisekelo zokuqhathanisa kuzohlala kuyikhono elibalulekile lonjiniyela.
