首先你要准备一个3d 摄像头。比如这样的。
28买的。。。640 x 480 ，有色车不推荐买。缺银子的可以考虑。自己焊usb线款的18。
只想本地看的 ，看这篇文章
将摄像头的视频数据通过 RTSP 输出。代码如下。
import cv2
import usb.core
import usb.backend.libusb1
from flask import Flask, render_template, Response
# cam=cv2.VideoCapture(1)
# backend = usb.backend.libusb1.get_backend(find_library=lambda x: "/usr/lib/libusb-1.0.so")
#
# dev = usb.core.find(idVendor=0x18e3, idProduct=0x5031, backend=backend)
# # simulate the SET_CUR sequence
# dev.ctrl_transfer(0x21,0x01,0x0800,0x0600,[0x50,0xff])
# dev.ctrl_transfer(0x21,0x01,0x0f00,0x0600,[0x00,0xf6])
# dev.ctrl_transfer(0x21,0x01,0x0800,0x0600,[0x25,0x00])
# dev.ctrl_transfer(0x21,0x01,0x0800,0x0600,[0x5f,0xfe])
# dev.ctrl_transfer(0x21,0x01,0x0f00,0x0600,[0x00,0x03])
# dev.ctrl_transfer(0x21,0x01,0x0f00,0x0600,[0x00,0x02])
# dev.ctrl_transfer(0x21,0x01,0x0f00,0x0600,[0x00,0x12])
# dev.ctrl_transfer(0x21,0x01,0x0f00,0x0600,[0x00,0x04])
# dev.ctrl_transfer(0x21,0x01,0x0800,0x0600,[0x76,0xc3])
class VideoCamera(object):
def __init__(self):

# from a webcam, comment the line below out and use a video file
# instead.
self.video = cv2.VideoCapture(1)

# as the main.py.

app = Flask(__name__)
@app.route('/')
def index():
return render_template('index.html')
def gen(camera):
while True:
frame = camera.get_frame()
yield (b'--frame\r\n'
b'Content-Type: image/jpeg\r\n\r\n' + frame + b'\r\n\r\n')

def video_feed():
return Response(gen(VideoCamera()),
mimetype='multipart/x-mixed-replace; boundary=frame')
if __name__ == '__main__':
app.run(host='0.0.0.0', debug=True)
然后通过访问 http://127.0.0.1:5000/video_feed 试试
如果可以去 openpose 执行
./build/examples/openpose/openpose.bin –ip_camera http://xxx.xxx.xxx.xxx:5000/video_feed
OK
直接访问 http://127.0.0.1:5000/video_feed 也可以看到，但推流部分还不支持多路并发，有时间再弄。
openpose 如何处理3d 视频流，以后再继续吧。
