python通过视频生成三维图像_python处理点云数据并生成三维点云模型

1.python代码：

1 import numpy as np

2 import matplotlib.pyplot as plt

3 from mpl_toolkits.mplot3d import Axes3D

4 #f=open('point cloud.txt','r')

5 f=open('11D-zhongxin1-1_RawXYZ_ds_part2.xyz','r')

6 point=f.read()

7 f.close()

8 l1=point.replace('\n',',')

9 l2=l1.split(',')

10 l2.pop()

11 #print(l2)

12 m1=np.array(l2[0:120000])

13 print(len(m1))

14 #m2=m1.reshape(265565,4)

15 m2=m1.reshape(30000,4)

16 print(m2)

17 m3=[]

18 for each in m2:

19 each_line=list(map(lambda x:float(x),each))

20 m3.append(each_line)

21 m4=np.array(m3)

22

23 x=[k[0] for k in m4]

24 y=[k[1] for k in m4]

25 z=[k[2] for k in m4]
