加速度计是高频采样，如何将UTC时间转换为浮点时间?

Question

import pandas as pd
df = pd.DataFrame(['Time':['16:47:55.510','16:47:55.511','16:47:55.410']})
df
output:
Time
0      16:47:55.510
1      16:47:55.511
2      16:47:55.410

如何使用 Python 将此时间值转换为浮点值？

Answer 1

如果时间是h：m：s.ms格式，你可以做这样的事情：

hours, minutes, seconds = df.Time[0].split(':')
total_seconds = int(hours) * 3600 + int(minutes) * 60 + float(seconds)
