Python 讀取資料

將乙個資料夾下面的影象和對應的pts讀進來，然後把pts檔案裡面的資料讀入乙個陣列，然後畫到影象上：

# -*- coding:utf-8 -*-

"""測試資料樣例
"# 讀取
image =cv2.imread(fullpath)
# 讀取對應的pts檔案
landmarks =readlmk(ptsfile)
for point in
landmarks:
cv2.circle(image,point,
1,(255,0,0
))                width = image.shape[0
]                height = image.shape[1
]                print (width,height)
if width > 800
:                    # 歸一化到1000
image = cv2.resize(image,(800,height*800/width))
cv2.imshow("ww
",image)
cv2.waitkey(10)
input = raw_input('
請輸入: ')
if input == "":
print (
"copy正確的資料來源")
newpath="
/users/anitafang/downloads/datasets/jiaozheng/2017sdm/sdm2/001/
"cmd = "
cp " + fullpath + "
" + ptsfile+ "
"+newpath
print cmd
os.system(cmd)
if __name__ == '
__main__':
main()

講一下python按行讀取檔案內容：

filename = "

/users/anitafang/downloads/datasets/jiaozheng/annot/sdm/001/annot/
"+cnt+"
.pts
"f1 =open(filename)
print(filename)
line_nu = 1
for line in
f1.xreadlines():
if line_nu > 51 and line_nu<72
:                # print(line)
linestr =line.strip()
# print(linestr)
linestrlist = linestr.split("\t"
)                # print(linestrlist)
# linelist = [int(i) for i in
linestrlist]
# print(linelist)
line_nu += 1
