Ana amfani da na'urorin auna nesa na Laser, LiDARs, da sauran na'urori sosai a masana'antu na zamani, binciken ƙasa, tuƙi mai sarrafa kansa, da na'urorin lantarki na masu amfani. Duk da haka, masu amfani da yawa suna lura da manyan bambance-bambancen aunawa lokacin da suke aiki a fagen, musamman lokacin da suke mu'amala da abubuwa masu launuka daban-daban ko kayan aiki. Babban dalilin wannan kuskuren sau da yawa yana da alaƙa da hasken abin da aka nufa. Wannan labarin zai zurfafa cikin tasirin hasken da ke nunawa akan auna nisa kuma ya samar da dabarun aiki don zaɓar abin da aka nufa.
1. Menene Watsawa kuma Me Yasa Yake Shafar Auna Nisa?
Nunin haske yana nufin ikon saman da ke nuna hasken da ya faru, wanda yawanci ake bayyana shi a matsayin kashi (misali, farin bango yana da hasken haske na kusan kashi 80%, yayin da robar baƙi ke da kashi 5% kawai. Na'urorin auna laser suna ƙayyade nisa ta hanyar ƙididdige bambancin lokaci tsakanin hasken da aka fitar da haske da wanda aka nuna (ta amfani da ƙa'idar Lokacin tashi). Idan hasken da aka yi niyya ya yi ƙasa sosai, zai iya haifar da:
- Ƙarfin Sigina Mai Rauni: Idan hasken da aka nuna ya yi rauni sosai, na'urar ba za ta iya ɗaukar sigina mai inganci ba.
- Kuskuren Ma'auni Mai Ƙaruwa: Tare da tsangwama mai yawa na hayaniya, daidaito yana raguwa.
- Takaitaccen Tsarin Aunawa: Matsakaicin nisan da zai iya raguwa da fiye da 50%.
2. Rarraba Hankali da Dabaru na Zaɓin Manufa
Dangane da halayen kayan gama gari, ana iya rarraba abubuwan da aka tsara zuwa rukuni uku masu zuwa:
① Manyan Manufofin Numfashi (>50%)
- Kayan Aiki Na Musamman: saman ƙarfe mai gogewa, madubai, farar yumbu, siminti mai launin haske
- Fa'idodi: Dawowar sigina mai ƙarfi, ya dace da ma'aunin daidaito mai tsayi (sama da mita 500)
- Yanayin Aikace-aikace: Binciken gini, duba layin wutar lantarki, duba ƙasa mara matuki
- Lura: A guji saman madubi wanda zai iya haifar da hangen nesa (wanda zai iya haifar da rashin daidaiton tabo).
② Manufofin Matsakaici na Nuni (20%-50%)
- Kayan Aiki Na Musamman: Itace, hanyoyin kwalta, bangon tubali mai duhu, tsire-tsire kore
- Matakan hana:
Rage nisan aunawa (an ba da shawarar <200m).
Kunna yanayin na'urar mai yawan amsawa.
Fi son saman da ba shi da matte (misali, kayan da aka yi da sanyi).
③ Manufofin Rage Haske (<20%)
- Kayan Aiki Na Musamman: Baƙar roba, tarin kwal, yadi mai duhu, jikin ruwa
- Haɗari: Sigina na iya ɓacewa ko kuma suna fama da kurakuran tsalle.
- Mafita:
Yi amfani da abin da ake kira retro-reflective maƙasudi (allon reflector).
Daidaita kusurwar laser zuwa ƙasa da 45° (don haɓaka haskakawar da ke yaɗuwa).
Zaɓi na'urori masu aiki a tsawon tsayin 905nm ko 1550nm (don ingantaccen shigar ciki).
3. Dabaru na Musamman na Yanayi
① Ma'aunin Manufa Mai Sauƙi (misali, abubuwan hawa masu motsi):
- Ba da fifiko ga lambobin lasisin abin hawa (wuraren da ke da hasken haske) ko kuma jikin motoci masu launin haske.
- Yi amfani da fasahar gane sauti da yawa (don tace ruwan sama da tsangwama).
② Maganin Fuskar Hannu Mai Hadari:
- Don ƙarfe mai launin duhu, a shafa matte (wanda zai iya inganta haske zuwa 30%).
- Sanya matatun polarizing a gaban bangon labulen gilashi (don danne hasken spectural).
③ Diyya ga Tsangwama ga Muhalli:
- Kunna algorithms na hana hasken bango a cikin yanayin haske mai haske.
- A lokacin ruwan sama ko dusar ƙanƙara, yi amfani da fasahar daidaita bugun zuciya (PIM).
4. Jagororin Daidaita Sigogi na Kayan Aiki
- Daidaita Wutar Lantarki: Ƙara ƙarfin laser don ƙananan abubuwan da ke nuna haske (tabbatar da bin ƙa'idodin amincin ido).
- Buɗewar Karɓa: Ƙara diamita na ruwan tabarau mai karɓa (ga kowane ninki biyu, ƙaruwar siginar tana ƙaruwa sau huɗu).
- Saitin Matsakaici: Daidaita matakin kunna siginar da ƙarfi (don guje wa kunna karya saboda hayaniya).
5. Abubuwan da ke Faruwa a Nan Gaba: Fasahar Biyan Kuɗi Mai Hankali
Tsarin auna nisa na zamani ya fara haɗawa:
- Kula da Gano Mai Daidaitawa (AGC): Daidaita yanayin amsawar na'urar daukar hoto a ainihin lokaci.
- Tsarin AI na Gane Kayan Aiki: Daidaita nau'ikan kayan aiki ta amfani da fasalulluka na yanayin echo waveform.
- Haɗakar Multispectral: Haɗa bayanai na haske da infrared don ƙarin cikakken bayani.
Kammalawa
Kwarewar halayen haske babban ƙwarewa ce don inganta daidaiton ma'auni. Ta hanyar zaɓar maƙasudai a kimiyyance da kuma daidaita na'urori yadda ya kamata, koda a cikin yanayin haske mai ƙarancin ƙarfi (ƙasa da 10%), ana iya cimma daidaiton ma'aunin matakin milimita. Yayin da fasahar diyya mai wayo ke tasowa, tsarin aunawa na gaba zai daidaita da "wayo" zuwa ga mahalli masu rikitarwa. Duk da haka, fahimtar ƙa'idodin haske na asali koyaushe zai zama ƙwarewa mai mahimmanci ga injiniyoyi.
