使用Pthon中的Opencv获取人体关键点并再在unity中展
为了给同门们做备忘录。细到扣脚没有你打我。细节细节细节(重要的......)
目录
一、环境配置
二、pycharm的操作
三、Unity中的操作
一、环境配置
电脑配置
1.1Python的下载安装
1.2Pycharm的下载安装
1.3Unity Hub的下载
在Hub里面下载Unity
1.3.1Unity的下载
1.3.2项目创建
1.4VisualStudio的下载
二、pycharm的操作 1建立项目(补上?) 2配置工具包
Pycharm专业版(professional)本来整的社区版的我也不知道为啥变成了这样。
先来配置环境进入File>Projectuserfiles(项目名称)Python Interpreter(这里已经是装了几个工具包的样子了)看看有哪些工具包,一会安装工具包也需要在这里。
书写代码,这里有个“BUG”能看出来的举手
from cvzone.PoseModule import PoseDetector import cv2 cap = cv2.VideoCapture("Video.mp4") detector = PoseDetector() hile True: suess, img = cap.read() img = detector.findPose(img) lmList, bboxInfo = detector.findPosition(img) cv2.imsho("Image", img) cv2.aitkey(1)
调出视频看看成成功不
报错了
File>Projectuserfiles(项目名称)>Python Interpreter>左下角的“+”号>
点开Manage Repositories更镜像源网站
点击小加号把网站放进去
https://pypi.tuna.tsinghua.edu./simple/
返回到这个页面再搜索框里输入想要的安装包名称
so 我们安装一下google
还有 protobuf
又有错误了
所以再安装matplotlib
So红色我的最爱
继续安装不过这里要安装“attrs”
成功了视频一闪而过并提示 ,错误在“aitKey”K要大写,(对这就是那个BUG)
from cvzone.PoseModule import PoseDetector import cv2 cap = cv2.VideoCapture("Video.mp4") detector = PoseDetector() hile True: suess, img = cap.read() img = detector.findPose(img) lmList, bboxInfo = detector.findPosition(img) cv2.imsho("Image", img) cv2.aitKey(1)
这样就成功了~ 模特是你们可爱的琦学长
这里只调动了CPU,并为启动GPU所以you'dai
运行
from cvzone.PoseModule import PoseDetector import cv2 cap = cv2.VideoCapture("Video.mp4") detector = PoseDetector() hile True: suess, img = cap.read() img = detector.findPose(img) lmList, bboxInfo = detector.findPosition(img) if bboxInfo: lmString = "" for lm in lmList: print(lm) cv2.imsho("Image", img) cv2.aitKey(1)
得出
下一步将数据存在文件中
import cv2 from cvzone.PoseModule import PoseDetector cap = cv2.VideoCapture('Video.mp4') detector = PoseDetector() posList = [] hile True: suess, img =cap.read() img = detector.findPose(img) lmList,bboxInfo = detector.findPosition(img) if bboxInfo: lmString = "" for lm in lmList: lmString += f'{lm[1]},{img.shape[0] - lm[2]},{lm[3]} , ' posList.append(lmString) print(len(posList)) cv2.imsho("Image",img) key = cv2.aitKey(1) if key == ord("1"):#按“1”按键这个整了4个小时,...(简直是天才~) ith open("data.txt","") as f: f.ritelines(['%sn'% item for item in posList])
这个“1”要在英文输入法中按切记。就这样我们得到了数据啦啦啦啦啦~
三、Unity中的操作
3.1Unity的配置
申请账号、
3.1建立项目
点击Create project
建立C#文件
这是导入并执行文件的代码可以显示动画咯
using System.Collections; using System.Collections.Generic; using UnityEngine; using System.Linq; using System.Threading; public class AnimationCode : MonoBehaviour { public GameObject[] Body; Listlines; int counter = 0; // Start is called before the first frame update void Start() { lines = System.IO.File .ReadLines("Assets/data.txt").ToList(); } // Update is called once per frame void Update() { string[] points = lines[counter].Split(','); for (int i = 0; i <= 32; i++) { float x = float.Parse(points[0 + (i 3)]) / 100; float y = float.Parse(points[1 + (i 3)]) / 100; float z = float.Parse(points[2 + (i 3)]) / 100; Body[i].transform.localPosition = ne Vector3(x, y, z); } counter += 1; if (counter == lines.Count) { counter = 0; } Thread.Sleep(30); } }
下一步就是在球球中间连线编辑C#文件
上代码了Script点的
using System.Collections; using System.Collections.Generic; using UnityEngine; using System.Linq; using System.Threading; public class AnimationCode : MonoBehaviour { public GameObject[] Body; Listlines; int counter = 0; // Start is called before the first frame update void Start() { lines = System.IO.File .ReadLines("Assets/202204131410(1).mp4.txt").ToList(); } // Update is called once per frame void Update() { string[] points = lines[counter].Split(','); for (int i = 0; i <=32; i++) { float x = float.Parse(points[0 + (i 3)]) / 100; float y = float.Parse(points[1 + (i 3)]) / 100; float z = float.Parse(points[2 + (i 3)]) / 300; Body[i].transform.localPosition = ne Vector3 (x,y,z); // Debug.Log(Body.Length); } counter += 1; if (counter == lines.Count) { counter = 0; } Thread.Sleep(90); } }
线的Script
using System.Collections; using System.Collections.Generic; using UnityEngine; public class LineCode : MonoBehaviour { LineRenderer lineRenderer; public Transform origin; public Transform destination; // Start is called before the first frame update void Start() { lineRenderer = GetComponent(); lineRenderer.startWidth = 0.05f; lineRenderer.endWidth = 0.05f; } // Update is called once per frame void Update() { lineRenderer.SetPosition(0, origin.position); lineRenderer.SetPosition(1, destination.position); } }
环境配置
- 安装python、IDE(pycharm)、Unity Hub、Unity、visual studio就不在这做讲解了(有其他的道友。)
得空了再填加。
