FRGC数据集abs格式转化xyz

FRGC数据集abs格式转化xyz格式：代码如下：

import os
readpath=''
writepath=''
if not os.path.exists(writepath):
    os.makedirs(writepath)
for root,dir,files in os.walk(readpath):
    for newfilename in files:
        abs_path=os.path.join(readpath,newfilename)
        print('newfilename',newfilename)
        absfile=open(abs_path,'r')
        xyzpath=os.path.join(writepath,os.path.splitext(newfilename)[0]+'.xyz')
        print('xyzpath',xyzpath)
        xyzfile=open(xyzpath,'w')
        tab=str.split(absfile.readline())
        rows=int(tab[0])
        tab=str.split(absfile.readline())
        columns=int(tab[0])
        tab=str.split(absfile.readline())
        flags=list(map(int,str.split(absfile.readline())))
        X=list(map(float,str.split(absfile.readline())))
        Y=list(map(float,str.split(absfile.readline())))
        Y_sorted=sorted(Y)
        size=in(Y_sorted)
        print(Y_sorted)
        Z=list(map(float,str.split(absfile.readline())))
        absfile.close()
        size=len(X)
        croppedface=[]
        for i in range(0,size):
            if flages[i]==1:
                if Y[I]> -150:
                    line=str(X[I]) + ' ' + str(Y[I]) + ' ' + str(Z[I]) + '\n'
                    xyzfile.write(line)
        xyzfile.close()
