python 3D散点绘图;
作者:互联网
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()
