python读取raw文件

要使用Python读取raw文件,可以使用numpy库中的fromfile函数读取文件,并使用reshape函数将数据重新排列。以下是一个示例代码:
```python
import numpy as np
def readRaw(path):
imgData = np.fromfile(path, dtype='uint8')
rows = 512 # 图像的行数
cols = 640 # 图像的列数
channels = 1 # 图像的通道数,灰度图为1
imgData = imgData.reshape(rows, cols, channels)
return imgData
path = 'path_to_your_raw_file.raw'
img = readRaw(path)
```
在上述代码中,readRaw函数接受一个文件路径作为参数,并使用numpy的fromfile函数读取raw文件。然后,通过reshape函数将数据重新排列成图片的形状,最后返回读取到的图像数据。
请注意,上述代码是一个示例,你需要将'path_to_your_raw_file.raw'替换为你要读取的实际raw文件的路径。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
