1. Ni ikihe gihe-cyindege (tof) sensor?

Ni ikihe gihe cyo-kamera? Ni kamera ifata indege yindege? Hari aho bihuriye nindege cyangwa indege? Nibyiza, mubyukuri ni inzira ndende!

Tof nigipimo cyigihe bisaba ikintu, ibice cyangwa umuraba kugirango ugendere intera. Wari uzi ko sisitemu ya Bat ya Bat ikora? Sisitemu yindege nayo irasa!

Hariho ubwoko bwinshi bwigihe-cyindege, ariko benshi ni igihe-cyindege na scaneri ya laser, ikoresha ikoranabuhanga yitwa lidar (gutahura urumuri rwitwa Lidar (Kumenya neza) kugirango upime ubujyakuzimu n'umucyo wa infrad.

Amakuru yakozwe kandi afatwa akoresheje amajwi ya tof afite akamaro kanini kuko ashobora guha isura yo mumaso, gushushanya ibidukikije bishingiye kubiranga isura, gushushanya ibidukikije ukoresheje slam (icyarimwe) a algorithms, nibindi byinshi).

Ubu buryo bukoreshwa cyane muri robo, imodoka zo kwitwara, ndetse nubu ibikoresho byawe bigendanwa. Kurugero, niba ukoresha huawei p30 pro, open RX17 Pro, LG G8 Thinq, nibindi, terefone yawe ifite kamera ya tof!

2. Nigute-igihe-cyindege cya sensor ikora?

Noneho, twifuza gutanga intangiriro ngufi yukuntu-sensosor sensor ni nuburyo ikora.

TofSensor koresha amababi mato kugirango usohoke urumuri rwinshi, aho urumuri rwavuyemo rukanda ikintu icyo ari cyo cyose kandi rugaruka kuri sensor. Ukurikije itandukaniro riri hagati yimpinduka zumucyo no kugaruka kuri sensor nyuma yo kugaragara nikintu, urusetino rushobora gupima intera iri hagati yikintu na sensor.

Uyu munsi, tuzashakisha inzira 2 uko twakoresha igihe cyurugendo kugirango umenye intera nimbaraga: ukoresheje igihembo cyigihe, no gukoresha icyiciro cyo guhinduranya amplitude.

Koresha igihe cyagenwe

Kurugero, ikora muguhuza intego hamwe na laser, hanyuma upima urumuri rwagaragaye hamwe numucyo wumucyo kugirango ushyire kure yikintu kugirango ubaze neza intera yagenze neza. Mubyongeyeho, itandukaniro muri laser kugarura igihe na burch uburebure noneho bukoreshwa mugukora icya kabiri cya digitale

Nkuko mubibona hejuru, urumuri rwa laser kirarangiye hanyuma ukareka ikintu kuri sensor. Hamwe na lazer igihe cyo gutaha, kamera ya tof irashobora gupima intera nyayo mugihe gito gitangwa umuvuduko wurugendo rworoshye. .

(umuvuduko wumucyo x igihe cyo guhaguruka) / 2

Tof guhindura intera

Nkuko mubibona, igihe kizatangira mugihe urumuri ruzimye, kandi iyo uwakiriye yakiriye urumuri, igihe kizasubiza igihe. Iyo ukuyemo kabiri, "igihe cyo guhaguruka" cyumucyo kiraboneka, kandi umuvuduko wumucyo uhoraho, intera irashobora kubarwa byoroshye ukoresheje formula hejuru. Muri ubu buryo, ingingo zose ziri hejuru yikintu zirashobora kugenwa.

Koresha icyiciro cya shift ya am

Ibikurikira, theTofIrashobora kandi gukoresha imiraba ikomeje kugirango itange urumuri rwicyiciro cyerekana urumuri rwimbitse nintera.

Icyiciro cya Shift ukoresheje Umuhengeri

By modulating the amplitude, it creates a sinusoidal light source with a known frequency, allowing the detector to determine the phase shift of the reflected light using the following formula:

Iyo c ari umuvuduko wumucyo (c = 3 × 10 × 10 × 10 × 10 × 10 × 8), λ ni uburebure bwumuyaga (λ = m 1)

Ibi bintu byose bibaho byihuse nkuko dukora kumuvuduko wurumuri. Urashobora kwiyumvisha neza kandi umuvuduko wa sensor zishobora gupima? Reka ntange urugero, urugendo rworoheje rugenda rwihuta ibirometero 300.000, niba ikintu gifite imyaka 5 kuri wewe kirimo amasegonda 33 gusa, ahwanye namasegonda 0.000000033! Wow! Kutivuga, amakuru yafashwe azaguha verisiyo ya 3d yukuri ya 3d kuri pigiseli kuri buri shusho.

Utitaye ku ihame ryakoreshejwe, ritanga isoko yoroheje imurikira ibintu byose yemerera sensoso kumenya ubujyakuzimu bwibintu byose. Igisubizo nkiki kiguha ikarita intera aho buri pigiseli ashyigikira intera kumanota ahuye. Ibikurikira nurugero rwamashusho ya tof:

Urugero rwishusho ya tof

Noneho ko tuzi ko tof ikora, kuki aribyiza? Kuki ubikoresha? Ni iki ari byiza? Ntugire ikibazo, hari ibyiza byinshi byo gukoresha sensor ya Tof sensor, ariko birumvikana ko hari imbogamizi.

3. Inyungu zo gukoresha igihe-cya sensor yindege

Gupima neza no gupima byihuse

Ugereranije nizindi sensor sensor nka ulsesound cyangwa lasers, sen-yindege ya sensor irashobora guhimba ishusho ya 3D igaragara vuba. Kurugero, kamera ya tof irashobora gukora rimwe gusa. Ntabwo aribyo gusa, sensor ya tof irashobora kumenya neza ibintu neza mugihe gito kandi ntabwo bigira ingaruka kubushuhe, igitutu cyikirere nubushyuhe, bigatuma iba imbere no hanze.

intera ndende

Kubera ko top sensor koresha lasers, nazo zishobora no gupima intera ndende kandi iringaniye hamwe nukuri. Toph Sensor irahinduka kuko ishobora kumenya hafi nuburyo bwose bwimiterere nubunini.

Birahinduka kandi muburyo ushobora gutunganya optics ya sisitemu yo gukora neza, aho ushobora guhitamo ubwoko bwo kwanduza kandi ushobora guhitamo ubwoko bwo kwanduza kandi wakira hamwe na lens kugirango ubone umurima wifuza.

Umutekano

Mpangayitse ko laser kuvaTofSensor azakubabaza amaso yawe? Ntugire ikibazo! Benshi mu majwi ya tof ubu bakoresha imbaraga-nkeya za laser nka soko yoroheje hanyuma uyitware hamwe na palses. Sensor yahuye nicyiciro 1 cya laser yumutekano kugirango habeho neza ijisho ryumuntu.

Igiciro cyiza

Ugereranije nandi manota ya 3d ubujyakuzimu nka sisitemu yoroheje ya kamera cyangwa scaser, senmer ya laf irahendutse cyane ugereranije nabo.

Nubwo izo mbogamizi zose, tof iracyariyo yizewe kandi uburyo bwihuse bwo gufata amakuru ya 3D.

4. Imipaka ya tof

Nubwo ToF ifite inyungu nyinshi, ifite nayo ntarengwa. Zimwe mu mbogamizi za tof zirimo:

• Itara

Niba ubuso bwiza cyane bwegereye cyane kuri tof sensor yawe, barashobora gutatanya urumuri rwinshi mubyakiriye kandi bigatuma ibihangano n'ibitekerezo bidakenewe, kubera ko ishaka kuvuga neza gupima kwitegura.

• Ibitekerezo byinshi

Iyo ukoresheje tof sensor ku mpande zose, zishobora gutera ibitekerezo bidakenewe, nkuko urumuri rushobora kwikuramo inshuro nyinshi, kugoreka ibipimo.

• Urumuri rwinshi

Gukoresha kamera ya tof hanze mumirasire yizuba irashobora gutuma hanze ikoreshwa rigoye. Ibi biterwa nuburemere bwizuba bwizuba bitera Ssersox pigiseri kugirango bidahwitse, bigatuma bidashoboka kumenya urumuri nyarwo rugaragarira mubintu.

• Umwanzuro

Tof sensor naLens ya tofirashobora gukoreshwa muburyo butandukanye. Kuva kuri 3D gushushanya, kwikora inganda, gufatanya kwanga, kwitwara ibinyabiziga, ubuhinzi, kugenda kwa robo, kumenyekana, gupima ibimenyetso, gupima, kugenzura, gukurikiranwa, gukurikiranwa, gukurikiranwa Gusaba ikoranabuhanga rya tof ntibigira iherezo.

Urashobora kutwandikira kubyo ukeneye.
