Sir Airffic GoUkangodziwa sensa, ungaone nthawi yomweyo zomwe kampani iliyonse ikubetchera.
Mitundu isanu ndi umodzi ya maso ndi mphamvu zozindikira
Kamera zimagwira kuwala ngati maso a munthu. Ndi zotsika mtengo, zopepuka ndipo zimaona mitundu ndi zilembo, choncho ndi zogwiritsidwa ntchito kwambiri.
LiDAR imaponya kuwala kwa laser ndi kuwerengera nthawi yobwerera kuti iyeze mtunda bwino. Imagwira ntchito mumdima, koma kulemera ndi mtengo ndi mavuto.
Radar imagwiritsa ntchito mafunde a wailesi. Imaona zinthu zakutali mu mvula, chifunga ndi mdima, choncho imatsogola popewa kugundana ndi kuzindikira ma drone.
Kamera za kutentha zimaona kusiyana kwa kutentha — zabwino kwambiri pofufuza anthu usiku ndi kupeza malo otentha pa madenga ndi mawaya a magetsi.
IMU (imayeza kuthamanga ndi kuzungulira) ndi GNSS (kupeza malo kudzera pa satellite monga GPS) ndi mphamvu zamkati za drone. Zikaphatikizidwa ndi sensa zoyang'ana kunja, ndi pomwe zimapereka kuuluka kolondola.
| Sensa | Mphamvu | Zofooka | Ntchito zazikulu |
|---|---|---|---|
| Kamera (yowoneka) | Yotsika mtengo, yopepuka, zambiri | Mdima, chifunga, kunyezimira | Kuzindikira, SLAM, kuyendera |
| Kamera ya stereo / ya kuzama | Mtunda wapafupi | Yosalondola kutali | Kupewa zopinga |
| LiDAR | Mtunda wolondola, imagwira mumdima | Yolemera, yodula, yofooka mu mvula | Kuyeza malo, kuzindikira mawaya opyapyala |
| Radar ya mmWave | Mvula, chifunga, usiku, kutali | Maonekedwe ang'onoang'ono | Detect-and-avoid, kuzindikira ma drone |
| Kamera ya kutentha | Imaona kutentha, yamphamvu usiku | Chithunzi chosamveka bwino | Kufufuza ndi kupulumutsa, kuyendera katundu |
| IMU + GNSS | Kuyenda kwake ndi malo ake | GNSS imalephera m'nyumba kapena ikasokonezedwa | Kukhazikika kwa ndege, kupeza njira |
Chifukwa chake kuphatikiza sensa kumasankha masewera
Sensa iliyonse ili ndi kufooka. Ukadalira imodzi yokha, drone imakhala yakhungu nthawi yomwe kufooka kumeneko kwaonekera.
Choncho kamera imazindikira kuti chinthu ndi chiyani, radar imatsimikizira kuti chili kutali bwanji, ndipo IMU imadzaza momwe drone yayendera. Izi ndi sensor fusion.
Makampani odziwa kuphatikiza amapanga ndege zimene zimapitiriza kugwira ntchito nyengo ndi malo zikasintha. Kusaima ndi khalidwe lamtengo wapatali kwambiri la drone yamalonda.
Mlengalenga wopanda GNSS udakweza mtengo wa sensa
Ma signal a GNSS samafika pansi pa milatho, m'ma tunnel kapena m'nyumba zosungiramo katundu. M'malo a nkhondo, kusokoneza ma signal mwadala kudakhala chizolowezi.
Kufunika kwa kuuluka ndi kamera ndi IMU zokha (kupeza njira mwa kuona) kudakwera kwambiri pambuyo pa 2022.
Izi si za asilikali okha. Ukadaulo womwewu umathandiza kuyendera m'nyumba ndi kutumiza katundu m'mizinda.
Sir Airffic GoKodi ingauluke wailesi ikalephera? Uwu ndi mayeso abwino kwambiri oona ngati kuuluka payokha ndi kwenikweni.
Zomwe zikuchitika mu msika wa sensa
Zigawo za kamera zopangidwa mochuluka za mafoni zidatsitsa kwambiri mtengo wa maso a drone.
Radar ndi LiDAR zikucheperachepera ndi kutsika mtengo chifukwa cha kuchuluka kwa magalimoto, choncho tsopano zikukwanira pa ma drone.
Choncho sensa zambiri zimakula ngati zotsalira za misika ikuluikulu yosakhudzana ndi ma drone. Akatswiri a drone ayenera kusiyana pa momwe amaphatikizira sensa ndi pa mapulogalamu, osati pa zigawo.
Mafunso ofunsidwa kawirikawiri
Kodi ma drone amagwiritsa ntchito sensa ziti popewa zopinga?
Kamera za stereo kapena za kuzama pafupi, radar kutali ndi nyengo yoipa, ndi LiDAR pa zinthu zopyapyala monga mawaya. Ndege zambiri zimaphatikiza zingapo.
Kodi kusiyana pakati pa LiDAR ndi radar ndi kotani?
LiDAR imagwiritsa ntchito kuwala kwa laser kuyeza mtunda mwatsatanetsatane ndi kupanga maonekedwe a 3D. Radar imagwiritsa ntchito mafunde a wailesi; si yatsatanetsatane koma imapeza zinthu zakutali mu mvula, chifunga ndi mdima.
