根据提供的引用内容,可以得知cv2.imread()函数可以读取指定路径下的图像文件,并将其转换为三维数组。其中,第三个维度为3表示图像是彩色的,如果是灰度图像则为1。因此,可以使用cv2.imread()函数读取指定路径下的图像文件,如下所示:
```python
img1 = cv2.imread(path1)
```
需要注意的是,cv2.imread()函数返回的是一个numpy数组,如果读取失败则返回None。同时,需要确保指定的路径下确实存在需要读取的图像文件。

img = cv2.imread(test_path,1)
As an AI language model, I don't have access to the specific file path you are referring to, but I can explain what the code line means.
`cv2.imread()` is a function provided by the OpenCV library in Python that reads an image from a file. The first argument `test_path` is the file path of the image to be read. The second argument `1` specifies that the image should be read in color mode, i.e., with all color channels (red, green, and blue) present. If `0` is provided instead of `1`, the image is read in grayscale mode.
The returned value of `cv2.imread()` is a NumPy array that represents the image data.
img_path, lab = line.strip().split('\t') #读入图片 img = cv2.imread(img_path)
这段代码是读入一张图片,并使用OpenCV库中的imread函数将其加载到内存中。具体来说,代码首先将读入的一行文本按照制表符分隔符划分成两部分,第一部分是图片的路径,第二部分是该图片的标签。然后,使用Python的strip函数去除路径字符串两端的空格,接着调用OpenCV库的imread函数读入该路径对应的图片。最后,将读入的图片赋值给img变量,以备后续使用。
