python格式转换【bin转csv】

将.bin文件转为指定的行、列的.csv格式文件

如下代码测试可用

import struct
import os
import pandas as pd
 
def xshow(filename, nx, nz):
    '''    filename:文件路径    nx:行    nz：列    '''
    f = open(filename, "rb")
    pic = np.zeros((nx, nz))
    for i in range(nx):
        for j in range(nz):
            c = f.read(8)
            if len(c) == 0:
                break
            data, = struct.unpack('d', c) # 解密bin数据
            data = round(data, 8)# 保留8位小数
            pic[i][j] = data
            f.close()
    return pic
father_path = os.getcwd()# 运行文件路径
read_path_bin = father_path + r'\points.bin'# 读取数据文件路径
​data_arry = xshow(read_path_bin,11,1)
father_path = os.getcwd()# 运行文件路径
write_path_csv = father_path + r'\***.csv'#写入运行路径下csv文件
np.savetxt(write_path_csv, data_arry, delimiter=",")
