将Python（PyKinect）Skeleton数据转换为Points（X，Y）(Converting Python (PyKinect) Skeleton data to Points (X,Y)

将Python（PyKinect）Skeleton数据转换为Points（X，Y）(Converting Python (PyKinect) Skeleton data to Points (X,Y))

这是一个非常简单的问题，但我是Python的新手，我似乎无法实现它。

我想将Python（PyKinect）中的Skeleton数据坐标转换为Points（X，Y）。 我知道类似的任务可以在C＃（使用Microsoft.Kinect库）中实现，如下面的代码：

var p = new Point[6]; Point shoulderRight = new Point(), shoulderLeft = new Point(); foreach (Joint j in data.Joints) { switch (j.ID) { case JointID.HandLeft: p[0] = new Point(j.Position.X, j.Position.Y); // ...

但是在Python中（使用PyKinect），我能够获取数据对象：

for index, data in enumerate(skeletons): p2 = data.SkeletonPositions[JointId.wrist_left] #test left wrist joint data object print ('p2', p2)

输出是：

('p2', <x=-0.5478253364562988, y=-0.5376561880111694, z=1.7154035568237305, w=1.0>)

但是，我似乎无法将其转换为Point(X,Y)格式。 我需要使用NumPy或其他一些外部Python库吗？ 任何建议真的很感激。

This is a pretty simple issue but I am new to Python and I can't seem to accomplish it.

I want to convert Skeleton data co-ordinates in Python (PyKinect) to Points (X,Y). I know that the similar task can be achieved in C# (using Microsoft.Kinect libraries) like the below code:

var p = new Point[6]; Point shoulderRight = new Point(), shoulderLeft = new Point(); foreach (Joint j in data.Joints) { switch (j.ID) { case JointID.HandLeft: p[0] = new Point(j.Position.X, j.Position.Y); // ...

In Python (using PyKinect) though, I am able to get the data object:

for index, data in enumerate(skeletons): p2 = data.SkeletonPositions[JointId.wrist_left] #test left wrist joint data object print ('p2', p2)

The output is:

('p2', <x=-0.5478253364562988, y=-0.5376561880111694, z=1.7154035568237305, w=1.0>)

But, I can't seem to convert it into Point(X,Y) format. Will I need to use NumPy or some other external Python library for this? Any suggestions would really be appreciated.

你可以使用regex来提取值，我不确定这是你正在寻找的但是试试这个：

import re p2 = "<x=-0.5478253364562988, y=-0.5376561880111694, z=1.7154035568237305, w=1.0>" p2 = re.findall("-?\d+.\d+",p2) p2_xy = p2[0],p2[1] print ("p2",p2_xy)

输出：

('ps', ('-0.5478253364562988', '-0.5376561880111694'))

或者如果你想要一个更清洁的版本：

import re p2 = "<x=-0.5478253364562988, y=-0.5376561880111694, z=1.7154035568237305, w=1.0>" p2 = re.findall("-?\d+.\d+",p2) print ("p2",p2[0],p2[1])

输出：

('p2', '-0.5478253364562988', '-0.5376561880111694')

You can use regex to extract the values, I am not sure if this is what you are looking for but try this:

import re p2 = "<x=-0.5478253364562988, y=-0.5376561880111694, z=1.7154035568237305, w=1.0>" p2 = re.findall("-?\d+.\d+",p2) p2_xy = p2[0],p2[1] print ("p2",p2_xy)

Output:

('ps', ('-0.5478253364562988', '-0.5376561880111694'))

Or if you want a more cleaner version:

import re p2 = "<x=-0.5478253364562988, y=-0.5376561880111694, z=1.7154035568237305, w=1.0>" p2 = re.findall("-?\d+.\d+",p2) print ("p2",p2[0],p2[1])

Output:

('p2', '-0.5478253364562988', '-0.5376561880111694')
