Nrog rau qhov kev tshwm sim ntawm kev lag luam duab, cov kws yees duab tau sim nrog txoj hauv kev los ua haujlwm nrog lub koob yees duab los tsim cov koob yees duab zoo thiab zoo siab uas tuaj yeem koom nrog cov neeg tuaj saib. Hauv xyoo 1970, cov tsheb ciav hlau tau siv rau qhov no, nrog rau cov cranes thiab cov tsheb thauj mus los. Lawv nqa cov khoom hnyav txog li 20 kilograms, piv nrog cov koob yees duab niaj hnub zoo li me me.

Garret Brown hauv xyoo 1970 tau sim nrhiav txoj hauv kev ua haujlwm nrog cov cuab yeej hnyav yam tsis muaj teeb meem, nws thiaj li tsim lub steadicam.

Steadicams yog dab tsi rau

Nov yog cov cuab yeej ua los ntawm lub tsho khuam thiab caj npab dag uas tuav lub koob yees duab nyob rau hauv txoj hauj lwm zoo li qub ntawm lub gimbal rig. Lub tsho khuam tuav caj npab, thiab qhov ntawd - cov cuab yeej, vim tias feem ntau ntawm cov khoom poob rau ntawm lub cev ntawm tus neeg teb xov tooj, tsis yog ntawm nws caj npab thiab xub pwg. Lub caj npab dag tshem tawm kev vibrations, cia tus kws yees duab taug kev thaum ua yeeb yaj kiab.

Qhov kom zoo dua ntxiv ntawm cov steadicam yog qhov tsis muaj qhov xav tau los saib lub koob yees duab rau framing thiab nce qhov ntautxav nrog tus saib sab nraud uas tso cai rau koj los kho qhov ua kom pom tseeb nrog qhov tseeb.

Steadicam yog lub koob yees duab stabilization system uas ua kom nws txav tau yooj yim hauv cov dav hlau sib txawv. Kev siv cov cuab yeej zoo li no tso cai rau koj kom tau txais cov duab zoo yam tsis muaj kev vibrations thiab co, tsis muaj kev siv nyiaj tsis tsim nyog. Tsis zoo li tus neeg tsav tsheb ciav hlau, steadicams yog ntau lub xov tooj ntawm tes. Kev siv lub zog ruaj khov txuag cov nqi tsheb thauj mus los thiab cov neeg ua haujlwm tau txais txiaj ntsig, txo lub sijhawm teeb tsa thiab ua kom cov txheej txheem tua sai.

Steadicam tsim

Qhov yooj yim tsim ntawm lub stabilizer tso cai rau koj los tsim koj tus kheej: cov qauv kev tshaj lij muaj xws li lub tsho khuam hnav ntawm tus neeg teb xov tooj, pantograph thiab ntsug ntsug. Lub kaw lus tuaj yeem nruab nrog cov khoom siv ntxiv: lub saib rau kev saib, cov roj teeb rov qab, mounts rau kev teeb tsa ntawm lub tsheb lossis lub nyoob hoom qav taub.

Txoj Cai Ua Haujlwm

Lub hauv paus ntawm steadicam yog txoj cai lub cev ntawm kev txuag hluav taws xob. Lub luv luv shocks kis mus rau lub lever thaum lub sij hawm lub zog ntawm tus neeg teb xov tooj yog extinguished los ntawm springs-shock absorbers ua rau hauv lub stabilizer. Nyob rau tib lub sijhawm, kev vibrations xa mus rau qhov system los ntawm tus neeg teb xov tooj lub cev tau them nyiaj. Lub caj npab dag ntawm lub stabilizer nws thiaj li oscillates ntawm ob qho kev sib txuas nrog txav pawg.

Kev sib txuas ntawm caj npab caij nplooj ntoos hlav thiab lub koob yees duab stabilization system yog optimized los ntawm peb-axis gimbal sib koom, tso cai rau lub steadicam flipped upside down thiab tig ib ncig ntawm ob axes. Xws li cov qauv tsim tso cai rau koj los tua panoramic txhaj tshuaj ntawm kev txav mus los. Lub koob yees duab steadicam, txawm tias DIY ib qho, tuaj yeem qaij, tig thiab yias tib lub sijhawm. Kev sib npaug yog nyob ntawm tib lub hauv paus ntsiab lus uas qhov sib npaug yog tswj los ntawm cov neeg taug kev tightrope. Yog hais tias lub koob yees duab yog mounted rau ntawm ib tug nruj ntsug ncej, thiab ib tug counterweight yog muab tso rau hauv nws qis, ces ib tug qauv yog tsim nrog ib tug nruab nrab ntawm lub ntiajteb txawj nqus ntawm lub koob yees duab thiab lub counterweight thiab ob lub zog.

Peb axes ntawm lub pob khawm gimble yog nyob rau hauv nruab nrab ntawm cov cab kuj steadicam. Ntawm lub koob yees duab txuas taw tes, lub ntiajteb txawj nqus ntawm qhov hnyav thiab lub koob yees duab nws tus kheej yog sib npaug.

Cov teebmeem ntawm kev ruaj khov thiab kev poob siab ntawm lub koob yees duab yog tsim tsis yog los ntawm lub caij nplooj ntoos hlav ntawm tes, tab sis kuj los ntawm Steadicam mechanism. Qhov no ua rau nws muaj peev xwm muab tso rau ntawm lub stabilizer, thaum qhov nruab nrab ntawm lub ntiajteb txawj nqus ntawm lub koob yees duab yog hloov, ib tug luj xyaum zoo ib yam li lub counterweight, vim hais tias nyob rau hauv cov ntaub ntawv no txoj cai ntawm lub sij hawm ntawm inertia ntawm loj pib ua hauj lwm. Nyob rau hauv rooj plaub no, lub chamber thiab lub counterweight yuav tsum tsis txhob muaj qhov hnyav tib yam.

Lub lever-based gimble sib koom ua ke them nyiaj rau qhov hnyav ntawm lub koob yees duab thiab tuaj yeem txav mus los thiab nqis ntawm cov cab kuj.

Electronics lossis mechanics?

Ib qho tseem ceeb ntawm lub steadicam yog lub peev xwm los kho lub koob yees duab hauv cov lus qhia sib txawv, uas yog qhov tseem ceeb rau kev tua thiab tswj tau yooj yim ntawm lub cuab yeej. Qhov no yog ua tiav los ntawm kev txhim kho thiab kho cov txee. Qhov tseem ceeb sib npaug yog qhov kev hloov kho ntawm qhov sib npaug ntsug, nrog rau cov kab ntsug ntsug thiab qhov sib npaug. Steadicam rau lub koob yees duab nrog gimbal installationhnyav rau hauv qab kom lub DSLR nyob twj ywm upright.

Thaum xaiv, nws tseem tsim nyog xav txog tias lub koob yees duab hnyav dua, tus neeg teb xov tooj nrawm dua. Nyob rau tib lub sijhawm, cov koob yees duab hnyav, vim muaj inertia thiab loj, ua kom cov yees duab du thaum tsiv. Cov qauv sib zog ua rau nyuaj rau kev ruaj khov thiab tuav raws sijhawm, thiab txawm tias ua pa tawm tuaj yeem cuam tshuam rau kev yees duab zoo.

Tsis zoo li lub tshuab hluav taws xob, lub tshuab hluav taws xob steadicam muab kev tswj tag nrho ntawm cov txheej txheem tua. Tus neeg teb xov tooj tuaj yeem tswj cov kev hloov maj mam ntawm lub koob yees duab thiab taug qab cov khoom txav los ntawm tilting lub tshuab nyob ib ncig ntawm cov ces kaum. Nws yuav luag tsis yooj yim sua kom rov tsim dua cov nyhuv tib yam nrog lub tshuab hluav taws xob stabilizer.

Qhov tsis zoo ntawm lub tshuab steadicam yog qhov nyuaj ntawm kev teeb tsa thiab ua haujlwm nrog nws. Txawm tias muaj tseeb tias cov tuam ntxhab muab cov lus qhia, kev teeb tsa yuav siv sijhawm ntau. Mechanical stabilizers xav tau kev sib cuam tshuam nrog tus neeg teb xov tooj ntau dua, tsis zoo li cov khoom siv hluav taws xob.

Electronic Steadicams

Lawv tsim suav nrog ntau lub gyroscopic sensors, uas yog vim li cas lawv hu ua gyroscopic steadicams. Nyob ntawm seb muaj pes tsawg tus sensors, ob- thiab peb-axis gyroscopic stabilization tshuab tau muab faib.

Qhov zoo thiab qhov tsis zoo

Qhov zoo ntawm cov hluav taws xob stabilizer yog qhov pib sib npaug thiab hloov kho: tus neeg teb xov tooj tuaj yeem pib tua tam sim. Feem ntau cov qauv steadicam yog customizabletilted nce thiab nqis kom tau qhov xav pom los ntawm hauv qab lossis saum toj kawg nkaus. Lub gyroscopic stabilizer cia li tuav lub kaum sab xis. Qhov tsis zoo ntawm cov cuab yeej hluav taws xob yog qhov tsis muaj peev xwm hloov pauv ntawm lub kaum ntse ntse thaum tua.

Qhov txiaj ntsig ntxiv ntawm lub tshuab hluav taws xob hluav taws xob yog tias tus neeg teb xov tooj tsis tas yuav nyob ze lub koob yees duab tas li. Txawm li cas los xij, nws kuj muaj qhov tsis zoo - tus nqi siab thiab hnyav hnyav.

Smartphone stabilizers

Tus qauv tsim ntawm steadicam rau lub xov tooj smartphone muaj cov ncej txav tau ntawm lub pob khawm, uas tau tsav los ntawm lub tshuab hluav taws xob, txuas nrog tus kov. Lub xov tooj smartphone tau muab tso rau hauv tus ncej thiab tsau rau hauv txoj haujlwm kab rov tav, uas tuaj yeem hloov pauv siv gyroscope sensors.

Lub thav duab nrog lub xov tooj smartphone tuaj yeem tig hauv cov dav hlau sib txawv yam tsis muaj kev xa mus rau tag nrho cov kab ke vim muaj kev sib cuam tshuam ntawm txhua yam qauv. Lub xov tooj tau teeb tsa tsis yog los ntawm tus neeg teb xov tooj txhais tes, tab sis los ntawm kev sib hloov ntawm tus ncej. Cov kev taw qhia ntawm kev sib hloov tuaj yeem ua dynamic lossis programmed.

Lub luag haujlwm tseem ceeb ntawm lub steadicam rau lub xov tooj yog kom nce qib co thaum thaij video. Txawm li cas los xij, qhov muaj peev xwm ntawm hluav taws xob stabilizer yog qhov dav dua:

  • Txhim hloov txoj haujlwm ntawm lub xov tooj smartphone ntawm lub dav hlau kab rov tav mus rau ib qho ntsug.
  • Synchronization nrog koj lub xov tooj ntawm Bluetooth, uas tso cai rau koj los tswj kev tua siv cov yuam sij ntawm tus tuav tuav.
  • Kev paub muaj peev xwmneeg.
  • Ntau hom kev tua thiab cov teebmeem tshwj xeeb.
  • Panorama shooting thiab Motion Timelapse.

Steadicam rau xov tooj tso cai rau koj tua cov duab zoo nkauj yam tsis muaj kev co, siv ntau yam kev ua haujlwm ruaj khov.
