Kuphatikiza kwa kamera ndi LiDAR kuti muzindikire bwino

Posachedwapa, gulu la sayansi la ku Japan lapanga lapaderakamera ya LiDARfusion sensor, yomwe ndi LiDAR yoyamba padziko lonse lapansi yomwe imagwirizanitsa nkhwangwa za kamera ndi LiDAR kukhala sensor imodzi. Mapangidwe apaderawa amathandizira kusonkhanitsa zenizeni zenizeni za data yaulere ya parallax. Kachulukidwe kake ka laser radar ndikwambiri kuposa masensa onse a laser radar padziko lapansi, zomwe zimathandiza kuzindikira zinthu zakutali komanso zolondola kwambiri.
Nthawi zambiri, LiDAR imagwiritsidwa ntchito molumikizana ndi makamera kuti adziwe bwino zinthu, koma pali kusiyana kwa data yomwe imapezedwa ndi magawo osiyanasiyana, zomwe zimapangitsa kuchedwa kwa ma calibration pakati pa masensa. Sensor yosakanikirana yomwe yangopangidwa kumene imaphatikiza kamera ndi LiDAR yokhazikika kwambiri kukhala gawo limodzi, kukwaniritsa kuphatikizika kwa data zenizeni popanda parallax, kuwonetsetsa kuti zotsatira zake zikuyenda bwino komanso zolondola.
Kuphatikiza kwa kamera ndi LiDAR kumakwaniritsa kuzindikira kwachinthu. Gululi limagwiritsa ntchito luso lapadera lopangira mawonekedwe kuti liphatikize kamera ndi LiDAR kukhala gawo lokhala ndi optical axis, zomwe zimathandizira kuphatikiza zenizeni zenizeni za data yazithunzi za kamera ndi data yamtunda wa LiDAR, kukwaniritsa kuzindikira kwazinthu zapamwamba kwambiri mpaka pano. Thelaser radarndi kusamvana kopitilira muyeso kuphatikizidwa ndi kachipangizo kapamwamba kwambiri padziko lonse ka laser kachulukidwe kachulukidwe ka fusion kachulukidwe kawo kachulukidwe ka mtengo wa laser wopangidwa, womwe umatha kuzindikira zopinga zing'onozing'ono pamtunda wautali, potero kuwongolera kusamvana ndi kulondola. Sensa yake yatsopano imakhala ndi kachulukidwe wa kuwala kwa madigiri 0.045 ndipo imagwiritsa ntchito ukadaulo wa laser scanning unit kuchokera ku osindikiza amitundu yambiri (MFPs) ndi osindikiza kuti azindikire zinthu zakugwa mpaka ma 30 centimita pamtunda wa 100 metres.
Kukhazikika kwakukulu komanso umwini wa galasi la MEMS laser radar amafuna magalasi a MEMS kapena ma mota kuti aziwunikiralaserkudera lalikulu komanso lokhala ndi kachulukidwe kwambiri. Komabe, mawonekedwe a magalasi a MEMS nthawi zambiri amakhala otsika, ndipo mota nthawi zambiri imatha mwachangu. Sensa yatsopano yophatikizikayi imapereka malingaliro apamwamba kuposa makina opangira magalimoto komanso kulimba kwambiri kuposa magalasi achikhalidwe a MEMS. Asayansi amagwiritsa ntchito zopanga zapamwamba, ukadaulo woyika zida za ceramic komanso ukadaulo wapamwamba kwambiri wopanga magalasi a MEMS kuti athandizire kuzindikira mwatsatanetsatane m'mafakitale osiyanasiyana monga magalimoto odziyimira pawokha, zombo, makina olemera, ndi zina zambiri.
