如何在Python中正确地将图像显示为具有步长过渡的3D绘图？

import numpy as np
import matplotlib.pyplot as plt
from PIL import Image

image = Image.open('image.jpg')
image_array = np.array(image)

fig = plt.figure(figsize=(10, 10))
ax = fig.add_subplot(111, projection='3d')
ax.view_init(elev=20, azim=45)  # 设置视角
ax.dist = 10  # 设置观察者与图像的距离

x, y = np.meshgrid(range(image_array.shape[1]), range(image_array.shape[0]))
z = image_array / 255.0  # 将像素值归一化到0-1之间

ax.plot_surface(x, y, z, cmap='viridis', linewidth=0, antialiased=True)

plt.show()
