Chiyambi
Kuyambira kumapeto kwa zaka za m'ma 1960 ndi kumayambiriro kwa zaka za m'ma 1970, njira zambiri zojambulira zithunzi za m'mlengalenga zasinthidwa ndi njira zojambulira zamagetsi ndi zamagetsi zomwe zimayenda m'mlengalenga komanso m'mlengalenga. Ngakhale kuti njira zamakono zojambulira zithunzi za m'mlengalenga zimagwira ntchito makamaka mu kuwala kowoneka bwino, njira zamakono zojambulira za m'mlengalenga ndi pansi zimapanga deta ya digito yophimba kuwala kooneka, madera a infrared, infrared yotentha, ndi microwave spectral. Njira zachikhalidwe zojambulira zithunzi za m'mlengalenga zidakali zothandiza. Komabe, njira zojambulira za m'mlengalenga zimaphatikizapo ntchito zambiri, kuphatikizapo zochitika zina monga kuyerekezera zinthu zomwe zili mumlengalenga, kuyeza zinthu, ndi kusanthula zithunzi za digito kuti zipeze zambiri.
Kuzindikira kutali, komwe kumatanthauza mbali zonse za njira zodziwira kutali zosakhudzana, ndi njira yomwe imagwiritsa ntchito maginito amagetsi kuti izindikire, kulemba ndikuyesa makhalidwe a chandamale ndipo tanthauzo lake linaperekedwa koyamba m'ma 1950. Gawo la kuzindikira kutali ndi mapu, limagawidwa m'njira ziwiri zodziwira: kuzindikira kogwira ntchito ndi kosachitapo kanthu, komwe kuzindikira kwa Lidar kumagwira ntchito, komwe kumatha kugwiritsa ntchito mphamvu zake zokha kutulutsa kuwala kwa chandamale ndikuzindikira kuwala komwe kumawonekera kuchokera pamenepo.
Kuzindikira ndi Kugwiritsa Ntchito kwa Lidar Yogwira Ntchito
Lidar (kuzindikira kuwala ndi kusinthasintha) ndi ukadaulo womwe umayesa mtunda kutengera nthawi yotulutsa ndi kulandira zizindikiro za laser. Nthawi zina Airborne LiDAR imagwiritsidwa ntchito mosinthana ndi kusanthula kwa laser yoyendetsedwa ndi mpweya, mapu, kapena LiDAR.
Iyi ndi tchati yodziwika bwino yowonetsa njira zazikulu zogwiritsira ntchito deta ya mfundo panthawi yogwiritsa ntchito LiDAR. Mukasonkhanitsa ma coordinates a (x, y, z), kusanja mfundo izi kungathandize kukonza bwino ntchito yopereka ndi kukonza deta. Kuwonjezera pa kukonza ma point a LiDAR, chidziwitso cha mphamvu kuchokera ku mayankho a LiDAR n'chothandizanso.
Mu ntchito zonse zowunikira kutali ndi mapu, LiDAR ili ndi ubwino wapadera wopeza miyeso yolondola kwambiri popanda kuwala kwa dzuwa ndi zotsatira zina za nyengo. Dongosolo lodziwika bwino lowunikira kutali lili ndi magawo awiri, laser rangefinder ndi sensor yoyezera malo, zomwe zimatha kuyeza mwachindunji malo mu 3D popanda kusokoneza mawonekedwe chifukwa palibe kujambula komwe kumachitika (dziko la 3D limajambulidwa mu 2D plane).
