python绘制3D散点图, 采用matplotlib库;
包引入:
import matplotlib.pyplot as plt
import mpl_toolkits.mplot3d as p3d
import numpy as np
fig = plt.figure()
ax = p3d.Axes3D(fig) // 这一个非常关键;
np.meshgrid()
x = list(range(0, grayImg.shape[0]))
y = list(range(0, grayImg.shape[1]))
X, Y = np.meshgrid(x, y) // X,Y;
z = imgCornor.reshape(grayImg.shape[0] * grayImg.shape[1])
ax.scatter(X, Y, z, c='b', s=10, alpha=0.05)
plt.show()
