Python读取TIF影像的多种方法

pip install Pillow

from PIL import Image
# 读取TIFF文件
image = Image.open('example.tiff')
# 显示图像信息
print(f"图像格式：{image.format}")
print(f"图像大小：{image.size}")
print(f"图像模式：{image.mode}")
from PIL import Image
# 读取TIFF文件
image = Image.open('example.tiff')
# 显示图像信息
print(f"图像格式：{image.format}")
print(f"图像大小：{image.size}")
print(f"图像模式：{image.mode}")

import numpy as np
import tifffile as tf           #tifffile是tiff文件的读取库
from PIL import Image
import cv2 as  cv
import gdal

path = r'C:/Users/HP/Desktop/tif/jpeg2000/Test_Images/tif/boat4_2100.tif'

img_tf = tf.imread(path)
print(img_tf.shape)                 #(2960, 1976, 3)

img = Image.open(path)         #可以读取单通道影像,读取3通道16位tif影像时报错(PIL.UnidentifiedImageError: cannot identify image file),支持4通道8位影像
arr = np.array(img)
print(arr.shape)

#arr = cv.imread(path,cv.IMREAD_UNCHANGED)        #(2960, 1976)
arr = cv.imread(path,1)                          #(2960, 1976, 3)   备注：4波段的影像在opencv的读取方式中，显示为前三个波段，而且读取顺序为BGR
print(arr.shape)

dataset = gdal.Open(path)
arr = dataset.ReadAsArray()          #(3, 2960, 1976)
arr = arr.transpose(1, 2, 0)         #(2960, 1976, 3)
print(arr.shape)

dataset = gdal.Open(path)
bands = dataset.RasterCount
for band in range(1, bands + 1):
    # 读取波段
    src_band = dataset.GetRasterBand(band)
    # 波段转数组
    band_arr = src_band.ReadAsArray()
    if band == 1:
        height = band_arr.shape[0]
        width = band_arr.shape[1]
        arr = np.zeros((height, width, bands), dtype=np.uint8)
    arr[:, :, band - 1] = band_arr
print(arr.shape)                     #(2960, 1976, 3)
