python下将两个三维数组拼接为一个数组的方式:
import numpy as np
l1 = np.zeros((7,8,10), np.float32)
l2 = np.ones((7,8,10), np.float32)
L1 = np.vstack((l1,l2))#纵向拼接(shape[0]方向)
L2 = np.hstack((l1,l2))#横向拼接(shape[1]方向)
L3 = np.dstack((l1,l2))#深度拼接(shape[2]方向)
print('数组l1的尺寸:', l1.shape)
print('数组l2的尺寸:', l2.shape)
print('数组L1的尺寸:', L1.shape)
print('数组L2的尺寸:', L2.shape)
print('数组L3的尺寸:', L3.shape)
输出结果为:
数组l1的尺寸: (7, 8, 10)
数组l2的尺寸: (7, 8, 10)
数组L1的尺寸: (14, 8, 10)
数组L2的尺寸: (7, 16, 10)
数组L3的尺寸: (7, 8, 20)
