Laser rangefinders, LiDARs, uye zvimwe zvishandiso zvinoshandiswa zvakanyanya mumaindasitiri emazuva ano, kuongorora, kutyaira kwega, uye zvemagetsi zvevatengi. Nekudaro, vashandisi vazhinji vanocherekedza kwakakura kuyerwa kutsauka kana vachishanda mumunda, kunyanya kana vachibata nezvinhu zvemavara akasiyana kana zvinhu. Mhedzisiro yekukanganisa uku kazhinji ine hukama nekutarisa kwechinangwa. Ichi chinyorwa chinozoongorora mabatiro ekuratidzira pakuyera kureba uye kupa mazano anoshanda ekusarudza chinangwa.
1. Chii chinonzi Reflectivity uye Sei Chichikanganisa Kuyera Kureba?
Reflectivity inoreva kugona kwepamusoro kuratidza chiedza chechiitiko, chinowanzotaridzwa sechikamu (semuenzaniso, mudhuri muchena une ratidziro inosvika 80%, ukuwo rabha nhema ichingova ne5%). Midziyo yekuyera yeLaser inotarisisa chinhambwe nekuverenga musiyano wenguva pakati pechiedza chakaburitswa uye chinoratidzwa (uchishandisa iyo Nguva-ye-Ndege musimboti). Kana kutarisisa kwechinangwa kwakadzikira, kunogona kutungamira ku:
-Isina Simba Chiratidzo Chesimba: Kana mwenje unoratidzwa usina kusimba, mudziyo haugone kutora chiratidzo chakakodzera.
-Kuwedzera Chiyero Chikanganiso: Nekukanganisa kweruzha rwepamusoro, kunyatso kuderera.
- Yakapfupikiswa Yekuyera Range: Iyo yakanyanya nhanho inoshanda inogona kudonha neinopfuura 50%.
2. Reflectivity Classification uye Target Selection Strategies
Zvichienderana nehunhu hwezvinhu zvakajairika, zvinangwa zvinogona kuiswa muzvikamu zvitatu zvinotevera:
① Yakakwirira Reflectivity Target (>50%)
-Zvakajairwa Zvishandiso: Yakakwenenzverwa simbi nzvimbo, magirazi, chena ceramics, light-ruvara kongiri
-Zvakanakira: Yakasimba chiratidzo chekudzoka, inokodzera kureba kureba (kupfuura 500m) yakakwirira-chaiyo zviyero.
-Mamiriro ekushandisa: kuongorora kwekuvaka, kuongororwa kwetambo yemagetsi, drone terrain scanning
-Cherechedza: Dzivisa nzvimbo dzegirazi dzinogona kutungamira kune zviratidziro (izvo zvinogona kukonzera kusarongeka kwemavara).
② Zvepakati Reflectivity Targets (20% -50%)
- Yakajairika Zvishandiso: Huni, asphalt migwagwa, rima zvidhinha madziro, girinhi zvidyarwa
- Countermeasures:
Pfupisa chinhambwe chekuyera (inokurudzirwa <200m).
Ita kuti mudziyo uve mukuru-sevhitivity mode.
Kuda matte nzvimbo (semuenzaniso, chando zvinhu).
③ Yakaderera Reflectivity Target (<20%)
-Zvekuita Zvishandiso: Rabha dema, marasha mirwi, machira akasviba, miviri yemvura
-Njodzi: Zviratidzo zvinogona kurasika kana kutambura nekusvetuka zvikanganiso.
- Mhinduro:
Shandisa retro-reflective target (reflector boards).
Gadzirisa iyo laser incidence angle kusvika pazasi 45 ° (kuti uwedzere kupararira kutaridzika).
Sarudza zvishandiso zvinoshanda pawavelengths ye905nm kana 1550nm (yekupinda zvirinani).
3. Special Scenario Strategies
① Dynamic Target Measurement (semuenzaniso, mota dzinofamba):
-Kutungamira marezinesi emotokari (nzvimbo dzepamusoro dzinoratidzira) kana miviri yemotokari ine mavara.
-Shandisa akawanda echo recognition tekinoroji (kusefa kunze kwemvura uye kukanganiswa kwemhute).
② Complex Surface Treatment:
- Kune simbi-yakasviba simbi, shandisa matte machira (ayo anogona kuvandudza reflectivity kusvika 30%).
-Isa polarizing mafirita pamberi pegirazi keteni madziro (kudzvanyirira kufungidzira).
③ Muripo weKukanganiswa Kwezvakatipoteredza:
-Gonesa kumashure mwenje kudzvinyirira algorithms mune yakajeka mwenje mamiriro.
-Mukunaya kwemvura kana chando, shandisa tekinoroji yepulse interval modulation (PIM).
4. Equipment Parameter Tuning Guidelines
-Kugadziriswa kweSimba: Wedzera simba relaser kune yakaderera-reflectivity tarisiro (ona kuteedzera miganhu yekuchengetedza maziso).
-Kugamuchira Aperture: Wedzera dhayamita yeinogamuchira lens (pakupetwa kwega kwega, kuwana kwechiratidzo kunowedzera kana).
-Threshold Setting: Nesimba gadzirisa chiratidzo chinokonzeresa chikumbaridzo (kudzivisa kukonzeresa kwenhema nekuda kweruzha).
5. Future Trends: Intelligent Reflectivity Compensation Technology
Inotevera-chizvarwa chekuyera kureba masisitimu ari kutanga kubatanidza:
- Adaptive Kudzora Kudzora (AGC): Chaiyo-nguva kugadzirisa kweiyo photodetector senitivity.
- Material Recognition AI Algorithms: Kufananidza mhando dzemhando uchishandisa echo waveform maficha.
- Multispectral Fusion: Kubatanidza mwenje unooneka uye infrared data kune yakazara yakazara kutonga.
Mhedziso
Kuziva hunhu hwe reflectivity ihwo hunyanzvi hwekuvandudza kuyerwa kwechiyero. Nekusarudza nesainzi zvinangwa uye kumisikidza michina nemazvo, kunyangwe mune yekupedzisira-yakaderera reflectivity scenarios (pazasi pe10%), millimeter-level kuyerwa kwayo kunogona kuwanikwa. Sezvo tekinoroji dzehungwaru dzekubhadhara dzichikura, masisitimu ekuyera emangwana anozochinja zvakanyanya "hungwaru" kune dzakaoma nharaunda. Nekudaro, kunzwisisa misimboti yekuratidzira kunogara kuri hunyanzvi hwakakosha kune mainjiniya.
