Default FreeTrack - TrackIR (skoro) zadarmo!
Již p?ed ?asem tu prob?hla diskuze o prográmku cam2pan. Ja osobn? mám zkušenost celkem dobrou, ale n?jak mi pouhé dv? osy p?estaly sta?it... No a te? jsem narazil na mnohem lepši variantu!!

Jedná se o prográmek FreeTrack. Princip snímání pohybu z?stává stejný (webkamera + LED), nicmén? již není použita pouze jedna LED, ale hned 4! Tím pádem je možné snímat krom pohybu do stran (a u n?j navíc rozlišit posun od rotace) i pohyb dop?edu/dozadu! Navíc se dají pomocí k?ivek nastavovat charakteristiky pom?ru snímane rychlosti/rychlosti pohybu v PC. Další nezpornou výjodou je, že program je distribuován (narozdíl od cam2pan) jako freeware.

Velmi slušný a ?esky psaný návod na sestrojení pot?ebného HW (neboli sv?telného obrazce t?eba na kšiltovku) byl tady, bohužel ale v dob? kdy píšu tenhle post je stránka nedostupná (ale ješt? v?era fungovala, tak t?eba zase bude) a jiný návod jsem nenašel.

Sám jsem ješt? sw netestoval, ale rozhodn? to prubnu b?hem n?kolika p?íštích dn?/týdn? a dám v?d?t své poznatky.

btw na zmín?né domácí stránce FreeTracku je i toto video p?ímo z LFS

uz nekolik dni pouzivam freetrack a maximalni spokojenost. Prubezne uz jsem psal zazitky na IRC a mam napsanej kus clanku o nem vcetne srovnani s cam2pan, ktere pouzivam hodne dlouho. Timto verejne dekuji kadovi za upozorneni, ze neco takoveho existuje, protoze jinak bych jezdil stale s cam2pan a o freetracku nemel tuseni

tady zatim male ukazkove video, jak to vypada za jizdy:

Já jsem zkoušel Cam2pan, ale dost mi to snižovalo FPS. Jaký máte zkušenosti v tomhle ohledu s freetrackem?

IR filtr predpokladam neni takovej problem sehnat. Spis teda jen vybrat vhodnou a levnou kameru.
Stacila by tahle? http://www.czechcomputer.cz/product.jsp?artno=39802
Otazkou je jak kvalitne bude snimat.

na ty superlevny kamery bacha... muzete pak taky zjistit, ze si nemuzete manualne nastavit uzaverku, a tim padem sice za plneho denniho svetla budete mit slibovanych 30fps, ale kdyz se seseri, klesnete na nakych 12 a je po ptakach... a kdo hraje porad za denniho svetla, ze?

ja bych asi doporucil vice nez osvedcenou Logitech QuickCam.

shanejte takove diody, ktere maji co nejvetsi vyzarovaci uhel. ja jsem pouzil tyhle a 50° je malo, musel jsem pred kazdou nalepit takovy rozptylovac svetla, aby to kamera brala i kdyz mam natocenou hlavu.. idelani by bylo je zdvojit a vzajemne je vychylit tak, aby pokryvaly vetsi oblast
