1. Ndeipi nguva-ye-kubhururuka (tof) sensor?

Ndeipi nguva-ye-kubhururuka kamera? Iyo kamera inobata ndege yendege? Ine chimwe chinhu chekuita nezvirongwa kana ndege? Zvakanaka, ndiyo chaiyo kure kure!

Tof chiyero chenguva chinotora chechinhu, chidimbu kana wave kuti ufambe kure kure. Wakanga uchiziva here kuti Sonar's Sonar system inoshanda? Nguva-ye-ndege mamiriro akafanana!

Kune marudzi mazhinji enguva-of-blass sensors, asi mazhinji enguva-ye-yekugeza mendenji uye anoshandisa tekinoroji inonzi Lidar (yakajeka yekukwenenzverwa uye kuyera kudzika kwezvinhu zvakasiyana-siyana mumufananidzo nekuvhenekera ine infrared mwenje.

Dhata inogadzirwa uye yakabatwa uchishandisa tof sensors inobatsira zvakanyanya sezvazvinogona kupa petaction yekuona, mushandirapu mashandisirwo ezvimiro uchishandisa slam (panguva imwe chete yekuona uye mepu) algorithms, uye zvimwe.

Iyi sisitimu inoshandiswa zvakanyanya mumarobhoti, mota dzekuzvidzidza, uye kunyange ikozvino yako nhare mbozha. Semuenzaniso, kana iwe uri kushandisa huawei p30 pro, oppo rx17 pro, lg g8 thinga, etc., foni yako ine tof kamera!

2. Nguva-ye-ndege-fletor sensor?

Zvino, isu tinoda kupa nhungamiro pfupi yeiyo nguva-ye-flight sensor uye kuti inoshanda sei.

TofSensors shandisa zvidiki laser kuti EMAP infrared mwenje, uko iyo inokonzeresa mwenje inobviswa chero chinhu uye inodzokera kune sensor. Zvichienderana nemusiyano wenguva pakati pekubuda kwechiedza uye kudzoka kune sensor mushure mekuratidzwa nechinhu, iyo sensor inogona kuyera chinhambwe pakati pechinhu uye sensor.

Nhasi, isu tichaongorora nzira dzekushandisa nadzo kuti tinoshandisa sei nguva yekufamba kusvika kure uye kudzika: tichishandisa nguva pulsing, uye kushandisa chikamu cheshuwa kweAmplitude mafungu akasungirirwa.

Semuenzaniso, zvinoshanda nekuvhenekera chinangwa ne laser, saka kuyera mwenje unoratidzwa ne scanner, uye wozoshandisa kumhanya kwechiedza kuti chigere chechidimbu chechinhu chekuverenga chinhambwe chinofamba. Uye zvakare, musiyano weLaser Kudzorera nguva uye wavelength inobva yashandiswa kugadzira chaiyo dijitital dhijitari 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 33 yekuvhara, uye zvinoratidzika mapepa ayo maitiro ake.

Sezvauri kuona pamusoro apa, laser mwenje unodzingwa wobva waburitsa chinhu chichienda kune iyo sensor. Neiyo laser yekudzoka nguva, tof makamera anokwanisa kuyera madaro akakwana munguva pfupi yenguva yakapihwa kumhanya kwekufamba kwechiedza. .

Sezvauri kuona, Timer anotanga apo mwenje wadzimwa, uye kana iye anogamuchira anowana kudzoka kwechiedza, nguva yakatarwa ichadzoka nguva yacho. Paunenge uchibvisa kaviri, "nguva yekubhururuka" yechiedza inowanikwa, uye kumhanya kwechiedza kunogara kuchingoitika, saka chinhambwe chinogona kuverengerwa nyore uchishandisa formula iri pamusoro. Nenzira iyi, mapoinzi ese pamusoro pechinhu chinogona kutsanangurwa.

Nekufambisa iyo yekukwikwidza, inogadzira sinusoidal sosi ine inozivikanwa frequency, ichibvumira iyo detector kuti uone kuongororwa kwechivhura kweiyo fomu inotevera:

Iko C ndiko kumhanya kwechiedza (c = 3 × 10 ^ 8 m / 8 m /

Zvese zvinhu izvi zvinoitika nekukurumidza kwazvo sezvatinoshanda nekumhanya kwechiedza. Unogona kufungidzira here kunyorwa uye kumhanyisa kwaanokwanisa kuyera? Rega ndipe muenzaniso wekumhanya kwemazana matatu emakiromita pane yechipiri, kana chinhu chiri kure nemhete kubva kwauri Wow! Kwete kutaura, iyo data yakabatwa ichakupa chaiyo yerudzi rwedhijitari yedhijitari ye pixel yega yega mumufananidzo.

Pasinei neiyo nheyo inoshandiswa, ichivapa mwenje inovhenekera iyo nzvimbo yese inobvumira kuti sensor kuti isarudze kudzika kwezvinhu zvese. Mhedzisiro yakadaro inokupa iwe chinhambwe mepu uko pixel yega yega inogonesa chinhambwe kuenda kunzvimbo inoenderana mune chiitiko. Inotevera muenzaniso weiyo tof range girafu:

Zvino zvatinoziva kuti Tof mabasa, Nei zvakanaka? Nei uchiishandisa? Ndezvipi zvakanaka? Usanetseka, pane zvakawanda zvakanakira kushandisa tof sensor, asi zvechokwadi kune mamwe miganho.

3. Zvakanakira kushandisa nguva-ye-ndege sensors

Yakarurama uye inokurumidza kuyerwa

Kuenzaniswa nedzimwe chinhambwe sensors sekuraita kana lasers, nguva-ye-yekubhururuka sensors inokwanisa kunyora iyo 3D mufananidzo wechiitiko nekukurumidza. Semuenzaniso, kamera yefodhi inogona kuita izvi kamwe chete. Kwete izvozvo chete, iyo tof sensor inokwanisa kuona zvinhu nenzira kwayo munguva pfupi uye haina kukanganiswa nekunyorova, kumanikidzwa kwemhepo uye kupisa, kuita kuti zviite zvese zvevaviri mumagariro uye nekunze kushandiswa.

kureba

Sezvo tof sensors vanoshandisa lasers, ivo zvakare vanokwanisa kuyera marefu marefu uye nemaruva akanyanya. Tof sensors inochinja-chinja nekuti ivo vanokwanisa kuona pedyo uye zvinhu zvakanyanyisa zvimiro zvese uye saizi.

Izvo zvinoshandurwawo mupfungwa kuti iwe unokwanisa kugadzirisa iyo Optics yehurongwa hwekuita, kwaunogona kusarudza transmitter uye kugamuchira mhando uye lens kuti uwane iyo inodiwa munda waunoda.

Kuchengetedzwa

Kunetseka kuti laser kubva kuTofSensor inokuvadza maziso ako? usanetseke! Vazhinji tof sensors izvozvi vanoshandisa yakaderera-simba infrared laser sosi yechiedza uye ichiya iyo ine yakasungirirwa purses. Iyo sensor inosangana nekirasi 1 Laser kuchengetedza maitiro kuti ive yakachengeteka ziso remunhu.

mutengo unoshanda

Kuenzaniswa nedzimwe 3D kwakadzika kwakadzika matekinoroji akadai sekurongedza mwenje kamera masisitimu kana laser righfinders, tof sensors yakachipa zvakanyanya ichienzanisa navo.

Pasinei nezvose izvi zvisingakwanisi, tof ichiri yakavimbika uye yakanyanya kutsanya nzira yekutora 3D ruzivo.

4. Kugumira kweTOF

Kunyangwe tof ine zvakawanda zvakanakira, zvine zvaripano. Zvimwe zvezvisikwa zveTof zvinosanganisira:

• Akapararira mwenje

Kana nzvimbo dzakajeka kwazvo dziri padyo nepamusoro pese pese pese pese pese padzinoita kuti ugamuchire uye gadzira mafungidziro uye afirere sensor chete kuti uongorore mwenje wagadzirira.

• Kuwanda kwekufunga

Paunenge uchishandisa tof sensors pamakona uye maumbirwo egungano, zvinogona kukonzera kuratidzwa kusingadiwe, sezvo mwenje unogona kubhururuka kakawanda, uchikanganisa kuyerwa.

• Chiedza Chiedza

Kushandisa iyo tof kamera yekubuda muzuva rakajeka rinogona kuita kunze kwekunze kwakaoma. Izvi zvinokonzerwa nekuwanda kwehukuru hwezuva rinokonzera sensor pixels kuti vakurumidze kuona, vachiita kuti zvisakwanise kuona mwenje chaiwo wakaratidzwa kubva pachinhu.
