Nkhaniyi ikufotokoza mwatsatanetsatane za ukadaulo wogwiritsa ntchito laser, kutsatira kusintha kwake m'mbiri, kufotokoza mfundo zake zazikulu, ndikuwonetsa momwe amagwiritsidwira ntchito mosiyanasiyana. Cholinga chake ndi mainjiniya a laser, magulu a kafukufuku ndi chitukuko, ndi masukulu ophunzitsa za kuwala, ndipo imapereka kusakaniza kwa mbiri yakale komanso kumvetsetsa kwamakono.
Chiyambi ndi Chisinthiko cha Laser Ranging
Zoyambira kumayambiriro kwa zaka za m'ma 1960, zoyambira zoyesera za laser zinapangidwa makamaka kuti zigwiritsidwe ntchito pankhondo [1Kwa zaka zambiri, ukadaulowu wasintha ndi kukulitsa ntchito zake m'magawo osiyanasiyana, kuphatikizapo zomangamanga, malo, ndi ndege [2], ndi kupitirira apo.
Ukadaulo wa laserndi njira yoyezera mafakitale yopanda kukhudzana ndi anthu yomwe imapereka zabwino zingapo poyerekeza ndi njira zachikhalidwe zoyezera pogwiritsa ntchito kukhudzana ndi anthu:
- Zimachotsa kufunika kokhudzana ndi malo oyezera, kuteteza kusintha komwe kungayambitse zolakwika muyeso.
- Amachepetsa kuwonongeka kwa malo oyezera chifukwa sakhudzana ndi kukhudzana ndi thupi panthawi yoyezera.
- Yoyenera kugwiritsidwa ntchito m'malo apadera pomwe zida zoyezera zachikhalidwe sizigwira ntchito.
Mfundo Zogwiritsira Ntchito Laser:
- Kusanthula kwa laser kumagwiritsa ntchito njira zitatu zazikulu: kusanthula kwa laser pulse, kusanthula kwa laser phase, ndi kusanthula kwa laser triangulation.
- Njira iliyonse imagwirizanitsidwa ndi miyeso yeniyeni yomwe imagwiritsidwa ntchito nthawi zambiri komanso milingo yolondola.
01
Kuchuluka kwa Kugunda kwa Laser:
Amagwiritsidwa ntchito makamaka poyeza mtunda wautali, nthawi zambiri kupitirira mtunda wa kilomita imodzi, ndi kulondola kochepa, nthawi zambiri pamlingo wa mita.
02
Kuchuluka kwa Gawo la Laser:
Yabwino kwambiri poyezera mtunda wapakati mpaka wautali, womwe nthawi zambiri umagwiritsidwa ntchito mkati mwa mamita 50 mpaka 150.
03
Kujambula kwa Laser Triangulation:
Amagwiritsidwa ntchito makamaka poyezera mtunda waufupi, nthawi zambiri mkati mwa mamita awiri, zomwe zimapereka kulondola kwakukulu pamlingo wa micron, ngakhale kuti ili ndi mtunda wochepa woyezera.
Mapulogalamu ndi Ubwino
Kujambula kwa laser kwapeza malo ake m'mafakitale osiyanasiyana:
Ntchito yomanga: Kuyeza malo, mapu a malo, ndi kusanthula kapangidwe kake.
MagalimotoKupititsa patsogolo njira zothandizira madalaivala (ADAS).
Zamlengalenga: Kujambula malo ndi kuzindikira zopinga.

Kujambula kwa laser, makamakaNthawi Yoyendera Ndege (TOF) kuyambira, ndi njira yomwe imagwiritsidwa ntchito kudziwa mtunda pakati pa gwero la laser ndi cholinga. Mfundo imeneyi imagwiritsidwa ntchito kwambiri m'njira zosiyanasiyana, kuyambira pa kuyeza mtunda kosavuta mpaka mapu ovuta a 3D. Tiyeni tipange chithunzi chofotokozera mfundo yoyendetsera laser ya TOF.
Njira zazikulu zogwiritsira ntchito laser ya TOF ndi izi:
Kutulutsa kwa Laser Pulse: Chipangizo cha laser chimatulutsa kuwala kochepa.
Ulendo wopita ku Target: Kugunda kwa laser kumadutsa mumlengalenga kupita ku cholinga.
Kuganizira kuchokera ku Target: Kugunda kwa mtima kumagunda chandamale ndipo kumaonekera mmbuyo.
Bwererani ku Gwero:Kugunda kwa mtima komwe kumawonetsedwa kumabwerera ku chipangizo cha laser.
Kuzindikira:Chipangizo cha laser chimazindikira kugunda kwa laser komwe kukubwera.
Kuyeza Nthawi:Nthawi yomwe imatengedwa pozungulira kugunda kwa mtima imayesedwa.
Kuwerengera Mtunda:Mtunda wopita ku cholinga umawerengedwa kutengera liwiro la kuwala ndi nthawi yoyezedwa.
Chaka chino, Lumispot Tech yatulutsa chinthu choyenera kugwiritsidwa ntchito mu gawo la kuzindikira la TOF LIDAR, lomwe ndiGwero la kuwala la LiDAR la 8-in-1Dinani kuti mudziwe zambiri ngati mukufuna
