本發(fā)明公開了一種運(yùn)動(dòng)捕獲數(shù)據(jù)壓縮、解壓縮方法，所述壓縮方法包括如下步驟：設(shè)定運(yùn)動(dòng)捕獲數(shù)據(jù)包括由PosX,PosY,PosZ三列數(shù)據(jù)構(gòu)成的位移數(shù)據(jù)和由RotX、RotY、RotZ、ω四列構(gòu)成的旋轉(zhuǎn)數(shù)據(jù)，每列數(shù)據(jù)中的每個(gè)數(shù)據(jù)為32位浮點(diǎn)數(shù)據(jù)；將32位浮點(diǎn)數(shù)據(jù)轉(zhuǎn)化為16位整數(shù)數(shù)據(jù)，得到PosX〞、PosY〞、PosZ〞三列位移數(shù)據(jù)和RotX〞、RotY〞、RotZ〞三列旋轉(zhuǎn)數(shù)據(jù)；對位移數(shù)據(jù)PosX〞、PosY〞、PosZ〞或旋轉(zhuǎn)數(shù)據(jù)RotX〞、RotY〞、RotZ〞進(jìn)行數(shù)據(jù)預(yù)測處理，得到待編碼數(shù)據(jù)；對待編碼數(shù)據(jù)進(jìn)行編碼；本發(fā)明針對運(yùn)動(dòng)捕獲數(shù)據(jù)進(jìn)行數(shù)據(jù)處理，壓縮無損高效、節(jié)省空間。
