心血来潮，写了一个简单的图片类型转化的小工具，遇到了一个问题
opencv(python) imread,imwiter函数无法读取中文路径
查到的解法
1
def cv_imread(file_path=""):
file_path_gbk=img_path.encode('gbk')
img_mat=cv2.imread(file_path_gbk.decode())
return img_mat
无用，不适用于python3.6 opencv，opencv不支持no-ascii字符
2
丑陋的补救
def cv_imread(filename):
img = cv2.imdecode(np.fromfile(filename, dtype=np.uint8), cv2.IMREAD_UNCHANGED)
return img
def cv_imwrite(filename, img, imgType):
cv2.imencode(imgType, img)[1].tofile(filename)
用np来读取
3 乌龟策略
遇到中文不处理
def check_contain_chinese(check_str):
for ch in check_str:
if u'\u4e00' <= ch <= u'\u9fff':
return True
return False
4 终极策略
不适用中文路径
PS：下次买电脑，我刚开始必上来就把系统编码设置成UTF8，GBK太蠢了
