Intangiriro
Kuva mu mpera za 1960 no mu ntangiriro za 1970, sisitemu nyinshi zisanzwe zo gufotora mu kirere zasimbuwe na sisitemu zo mu kirere zikoresha amashanyarazi n'ibikoresho by'ikoranabuhanga. Nubwo gufotora mu kirere bisanzwe bikora cyane cyane mu isanzure ry'urumuri rugaragara, sisitemu zigezweho zo gufotora mu kirere no ku butaka zikora amakuru ya digitale akubiyemo urumuri rugaragara, infrared reflective, infrared thermal, na micro-onde spectral regions. Uburyo gakondo bwo gusobanura amashusho mu gufotora mu kirere buracyafasha. Nyamara, gufotora mu kirere bikubiyemo ibikorwa byinshi, harimo ibikorwa by'inyongera nko gushushanya imiterere y'ibintu, gupima ibintu mu kirere, no gusesengura amashusho mu buryo bwa digitale kugira ngo hamenyekane amakuru.
Gupima kure, bivuga ku bice byose by'ubuhanga bwo gupima kure bitanyuze mu buryo bworoshye, ni uburyo bukoresha amashanyarazi kugira ngo bumenye, bwandike kandi bupime imiterere y'ikintu runaka kandi ibisobanuro byatanzwe bwa mbere mu myaka ya 1950. Urwego rwo gupima kure no gukora ikarita, rugabanyijemo uburyo bubiri bwo gupima: gupima imikorere n'imikorere idakora, aho gupima Lidar ari imikorere, ishobora gukoresha ingufu zayo kugira ngo yohereze urumuri ku kintu runaka no kumenya urumuri ruturutse kuri cyo.
Gusuzuma no gukoresha Lidar Active
Lidar (gupima urumuri no gupima uburebure) ni ikoranabuhanga ripima intera hashingiwe ku gihe cyo gutanga no kwakira ibimenyetso bya laser. Hari igihe Airborne LiDAR ikoreshwa mu buryo butandukanye no gupima, gukoresha ikarita, cyangwa LiDAR mu kirere.
Iyi ni imbonerahamwe isanzwe igaragaza intambwe z'ingenzi zo gutunganya amakuru y'ingingo mu gihe cyo gukoresha LiDAR. Nyuma yo gukusanya imirongo ya (x, y, z), gutondekanya izi ngingo bishobora kunoza imikorere y'itangwa n'itunganywa ry'amakuru. Uretse gutunganya amanota ya LiDAR mu buryo bwa geometrike, amakuru y'ubukana bw'ibitekerezo bya LiDAR na yo ni ingirakamaro.
Mu buryo bwose bwo gupima no gukoresha ikarita, LiDAR ifite inyungu idasanzwe yo kubona ibipimo nyabyo bitandukanye n'izuba ryinshi n'izindi ngaruka z'ikirere. Sisitemu isanzwe yo gupima ikoresheje laser igizwe n'ibice bibiri, icyuma gipima ahantu hifashishijwe laser n'icyuma gipima ahantu hifashishijwe ikoranabuhanga, gishobora gupima ahantu hifashishijwe ikoranabuhanga rya 3D mu buryo butaziguye nta guhindagurika kw'imiterere y'ikirere kuko nta gishushanyo mbonera kiba kirimo (isi ya 3D ifatwa mu buryo bwa 2D).
BIMWE MU BIKORWA BYACU BYA LIDAR
Amahitamo y'isoko rya laser ya LiDAR idakoresha amaso kuri sensor
