Laser Rangefinder vs GPS: Nigute wahitamo igikoresho cyiza cyo gupima?

Mubyerekeranye nubuhanga bugezweho bwo gupima, laser rangefinders nibikoresho bya GPS nibikoresho bibiri bikoreshwa cyane. Haba kubintu byo hanze, imishinga yo kubaka, cyangwa golf, gupima intera nyayo ni ngombwa. Ariko, abakoresha benshi bahura nikibazo mugihe bahisemo hagati ya laser rangefinder nigikoresho cya GPS: niyihe ihuye nibyo nkeneye? Iyi ngingo izagereranya haba muburyo bwo kumenya ukuri, ibintu bishobora gukoreshwa, guhuza ibidukikije, nibindi byinshi, bigufasha gufata icyemezo kiboneye.

1. Amahame shingiro: Itandukaniro ryibanze hagati yubuhanga bubiri

Ikirangantego cya laser kigena intera mukurekura laser pulse no kubara igihe bifata kugirango urumuri rugaruke nyuma yo kwerekana intego. Ubusobanuro bwabwo bushobora kugera kuri milimetero kandi nibyiza kubipimo byihuse, byuzuye mubipimo bigufi (mubisanzwe metero 100-1500), bitewe numurongo utabangamiye.

GPS, kurundi ruhande, ibara imiterere yimiterere yimiterere yakira ibimenyetso bya satelite hanyuma ikabona amakuru yintera ishingiye kumihindagurikire yibi bikorwa. Akarusho kayo nuko bidasaba umurongo utaziguye wo kureba ku ntego kandi ushobora gukwirakwiza intera yisi. Ariko, bigira ingaruka cyane kubububasha bwibimenyetso, ikirere, nimbogamizi nkinyubako.

2. Kugereranya Imikorere Yingenzi

Ibipimo byo gupima

Ikirangantego cya Laser, mubihe byiza (nta guhuza urumuri gukomeye, kwerekana intego nziza), birashobora kugera ku kuri kuva kuri mm 1 kugeza kuri cm 1 cm, bigatuma bahitamo guhitamo imirima yihariye nkubushakashatsi bwubwubatsi ndetse nigishushanyo mbonera. Ibinyuranye, ubunyangamugayo bwibikoresho byo mu rwego rwa GPS mubusanzwe buri hagati ya metero 1 na 5, kandi birashobora guterwa cyane no gukwirakwiza ibyogajuru no gutinda kw'ibimenyetso. Ndetse hamwe na tekinoroji itandukanye ya GPS (DGPS), ibisobanuro ntibishoboka guca inzitizi kurwego rwa metero. Kubwibyo, niba ushaka ibisobanuro nyabyo, laser rangefinder niyo guhitamo neza.

Guhuza n'imihindagurikire y'ibidukikije

Ibikoresho bya Laser bisaba inzira itabujijwe kugera kuntego, kandi imikorere yabo irashobora kwangirika mubihe nkimvura, shelegi, igihu, cyangwa urumuri rwinshi rushobora guca intege laser. Ibikoresho bya GPS bikora neza ahantu hafunguye, ariko birashobora gutakaza ibimenyetso mumijyi yo mumijyi, tunel, cyangwa amashyamba yinzitane. Kubwibyo, kubutaka bugoye cyangwa intera ndende, GPS itanga byinshi byoroshye.

Imikorere no kwaguka

Laser rangefinders kabuhariwe mu gupima intera, uburebure, na mfuruka, hamwe na moderi zimwe zohejuru zohejuru zitanga ibintu nkibice / kubara kubara no kohereza amakuru ya Bluetooth. Ibinyuranye, ibikoresho bya GPS bitanga ibikorwa byinyongera nko gutegura inzira yo kugendagenda, gupima ubutumburuke, no gukurikirana inzira zigenda, bigatuma bikwirakwira hanze cyangwa kugendesha ibinyabiziga. Kubwibyo, mubihe hamwe nibisabwa byinshi, GPS itanga agaciro keza.

3. Basabwe Gusaba Ibihe

4. Guhitamo gute?

Icyemezo ahanini giterwa nibisubizo byibibazo bitatu bikurikira:

① Ukeneye uburebure bwa milimetero?

Niba ari yego, hitamo urutonde rwa laser.

② Ese igipimo cyawe cyo gupima kirenze km 1?

Niba ari yego, hitamo GPS cyangwa ihuriro rya GPS na laser rangefinder.

③ Urimo kuyikoresha mubutaka bugoye?

Niba ari yego, GPS ni iyo kwizerwa, ariko menya neza ko ibimenyetso biguma bihamye.

Hamwe niterambere ryikoranabuhanga, sisitemu ya Hybrid ihuza LiDAR (Laser Detection na Ranging) na GPS yatangiye gukoreshwa mubice nko gutwara ibinyabiziga byigenga no gushushanya geografiya. Ibi bikoresho birashobora kubona umurongo ngenderwaho wisi yose ukoresheje GPS mugihe ukoresheje laser yogusuzuma kugirango ubyare moderi ya 3D nyayo, bigere ku nyungu zibiri za "macroscopique positioning + gupima microscopique." Kubakoresha muri rusange, guhitamo ibikoresho byubwenge bishyigikira ubufatanye bwuburyo bwinshi bishobora kuba amahitamo meza mugihe kizaza.

Nta busumbane bwuzuye hagati ya laser rangefinders nibikoresho bya GPS. Urufunguzo nuguhuza ibyo ukeneye. Niba ukeneye gupima neza kandi neza intera ngufi, laser rangefinder niyo ujya. Kubirebire-burebure cyangwa ibidukikije bigoye, ibikoresho bya GPS birakwiriye. Kubakoresha umwuga, igisubizo kivanze gihuza ibyiza byombi gishobora kuba igisubizo cyanyuma.
