Izindaba - Ungathuthukisa Kanjani Ukunemba Kwesikali Se-Laser Rangefinder

Ukuthuthukisa ukunemba kwe-laser rangefinder kubalulekile ezimweni ezehlukene zokulinganisa ukunemba. Noma ngabe kusekukhiqizweni kwezimboni, ukuhlola kwezokwakha, noma izinhlelo zokusebenza zesayensi nezempi, ukuhluka kwelaser enembe kakhulu kuqinisekisa ukuthembeka kwedatha kanye nokunemba kwemiphumela. Ukuze kuhlangatshezwane nezidingo zokunemba eziqinile ezimweni ezihlukene, izindlela ezilandelayo zingathuthukisa ngempumelelo ukunemba kokulinganisa kwe-laser rangefinders.

1. Sebenzisa Ama-Lasers Asezingeni Eliphezulu

Ukukhetha i-laser yekhwalithi ephezulu kubalulekile ekuthuthukiseni ukunemba kokulinganisa. I-laser yekhwalithi ephezulu ayinikezi nje kuphela ukuzinza okukhulu kodwa futhi ikhipha umsebe wekhwalithi ephezulu. Ngokukhethekile, i-engeli yokuhluka kwe-laser kufanele ibe ncane ngangokunokwenzeka ukuze kuncishiswe ukusakazeka ngesikhathi sokudlulisela, ngaleyo ndlela kwehlise ukulahleka kwesignali. Ukwengeza, amandla okukhipha i-laser kufanele abe phezulu ngokwanele ukuze kuthuthukiswe ukuqina kwe-beam, kuqinisekiswe ukuthi isignali ihlala iqine ngokwanele ngisho nangemva kokudluliswa kwebanga elide. Ngokusebenzisa ama-laser analezi zici, amaphutha okulinganisa abangelwa ukwehluka kwe-beam kanye nokunciphisa isignali angancishiswa, ngaleyo ndlela kuthuthukiswe ukunemba.

2. Lungiselela Idizayini Yomamukeli

Idizayini yomamukeli ithinta ngqo amandla okwamukela isignali ye-laser rangefinder. Ukuze kuthuthukiswe ukusebenza komamukeli, ama-photodetectors azwela kakhulu kufanele akhethwe ukuze athwebule amasiginali abuyayo abuthaka. Umamukeli kufanele futhi abe nesilinganiso esihle sesignali-kuya-noise (SNR) ukuze kuncishiswe ukuphazamiseka komsindo wangemuva ezindaweni eziyinkimbinkimbi. Ukusebenzisa izihlungi ezisebenza kahle nakho kubalulekile, njengoba zingakwazi ukuhlunga amasiginali wokuphazamiseka okungadingekile, zigcine kuphela ama-echoes e-laser awusizo, ngaleyo ndlela zithuthukise ukunemba kokulinganisa. Ngokuthuthukisa idizayini yomamukeli, amandla okuthwebula isiginali we-laser rangefinder angathuthukiswa kakhulu, okuholela ekunembeni okuthuthukisiwe.

3. Thuthukisa Ukucutshungulwa Kwesiginali

Ukucubungula isignali kuyisici esibalulekile ekunqumeni ukunemba kwesilinganiso. Ama-algorithms okucutshungulwa kwesignali athuthukisiwe, afana nokukalwa kwesigaba noma ubuchwepheshe besikhathi sendiza (TOF), angakhuphula ukunemba kwezilinganiso zesignali yokubuyisela. Isilinganiso sesigaba sibala ibanga ngokuhlaziya umehluko wesigaba kusiginali ye-laser, efanele izilinganiso zokunemba okuphezulu; Ubuchwepheshe be-TOF bukala isikhathi esithathiwe ukuze i-laser ihambe isuka kusithumeli iye kumamukeli, ilungele izilinganiso zebanga elide. Ukwengeza, ukwandisa inani lezilinganiso nokulinganisa imiphumela kunganciphisa ngempumelelo amaphutha angahleliwe, ngaleyo ndlela kuthuthukise ukuzinza nokuthembeka kwemiphumela yokulinganisa. Ngokuthuthukisa amandla okucubungula isignali, ukunemba kokulinganisa kwezitholi ze-laser kungathuthukiswa kakhulu.

4. Thuthukisa i-Optical Design

Idizayini yokubona idlala indima ebalulekile ezinhlelweni ezihlukanisa i-laser. Ukuze kuthuthukiswe ukunemba kokulinganisa, isistimu yokubona kufanele ibe nokungqubuzana okuphezulu nokunemba okugxilile. I-Collimation iqinisekisa ukuthi i-laser beam ihlala ihambisana lapho ikhishwa, inciphisa ukusakazeka emoyeni, kuyilapho ukugxila okunembayo kuqinisekisa ukuthi i-laser beam igxiliswe ngokunembile endaweni okuhlosiwe nokuthi i-beam ebuyayo ingena ngokunembile kumamukeli. Ngokulinganisa ngokunembile isistimu ye-optical, amaphutha ngenxa yokuhlakazeka kwe-beam nokucabangela kungancishiswa ngempumelelo, ngaleyo ndlela kuthuthukiswe ukunemba.

5. Yehlisa Umthelela Emvelweni

Izici zemvelo zingathinta kakhulu ukuhlukahluka kwe-laser. Ngesikhathi sokulinganisa, uthuli olusemoyeni, umswakama uyashintsha, nezinga lokushisa kungaphazamisa ukusakazeka kwe-laser beam kanye nokwamukela amasignali okubuya. Ngakho-ke, ukugcina indawo yokulinganisa ezinzile kubalulekile. Izembozo zothuli zinganqanda uthuli ekuphazamisekeni kwe-laser beam, futhi amasistimu okulawula izinga lokushisa angagcina izinga lokushisa elizinzile lemishini. Ukwengeza, ukugwema ukulinganisa ezindaweni ezinokukhanya okuqinile noma izindawo eziningi ezikhanyayo kunganciphisa umthelela wokukhanya kwe-ambient kusiginali ye-laser. Ngokunciphisa imithelela yemvelo, ukunemba nokuzinza kwe-laser rangeing kungathuthukiswa.

6. Sebenzisa Okuqondiwe Okubonakalayo Okuphezulu

Ukubonakala kwendawo okuqondiswe kuyo kuthinta ngqo ukusebenza kwe-laser range. Ukuze kuthuthukiswe ukunemba kokulinganisa, izinto ezibonisa ukukhanya okuphezulu noma ama-coatings angasetshenziswa endaweni okuqondiwe kuyo, ngaleyo ndlela kwandise amandla esignali ye-laser echo ebuyisiwe. Ezimeni ezidinga izilinganiso ezinembile, amapuleti aqondiwe aklanywe ngokukhethekile abonisa ukukhanya okuphezulu angathuthukisa ukusebenza kwe-rangefinder, aqinisekise ukunemba kwemiphumela yokulinganisa.

7. Faka Ukulungiswa Kwebanga

Ezilinganisweni zebanga elide, amaphutha angase avele ngenxa yokunciphisa isignali ye-laser nokuhlehla emoyeni. Ukuze kunxeshezelwe lawa maphutha, ama-algorithms okulungisa ibanga noma amathebula okulungisa angasetshenziswa ukulungisa imiphumela yokulinganisa. Lawa ma-algorithms okulungisa ngokuvamile asekelwe kuzimiso zokusebenza ze-laser rangefinder kanye nezimo ezithile zokulinganisa, ehlisa ngempumelelo amaphutha ezilinganisweni zebanga elide futhi ngaleyo ndlela kuthuthukiswe ukunemba.

Isiphetho

Ngokuhlanganisa izindlela ezingenhla, ukunemba kwe-laser rangefinders kungathuthukiswa kakhulu. Lezi zindlela azithuthukisi nje kuphela ukusebenza kobuchwepheshe kwezithonjana ze-laser kodwa futhi zicabangela izici zemvelo neziqondiswe, zivumela isitholi sebanga ukuthi sigcine ukunemba okuphezulu kulo lonke uhla olubanzi lwezinhlelo zokusebenza. Lokhu kubaluleke kakhulu emikhakheni efana nokukhiqizwa kwezimboni, ukuhlola kwezokwakha, nocwaningo lwesayensi, lapho idatha enembayo ephezulu ibalulekile.
