python:在python中使用opencv进行摄像头编程初体验
闲着没事做，前段时间买了个摄像头，在ubuntu上用。打开cheese这个软件，一片空白，怎么不能用阿！google一番，装上gspca，还是不能用！
用lsusb命令查看下
lingshangwen@eagle:~$ lsusb

Bus 004 Device 001: ID 0000:0000

摄像头已经被识别出来，怎么就是不能用阿!!!!!!
还是自己动手，用python+opencv写段简单的代码吧，然后就有了下面的代码：
Python代码
[*]import wx
[*]
from opencv.cv import *
[*]
from opencv.highgui import *
[*]
[*]
class MyFrame(wx.Frame):
[*]
def __init__(self):
[*]
wx.Frame.__init__(self, None, -1, 'camera')
[*]
self.SetClientSize((640, 480))
[*]
[*]
self.cap = cvCreateCameraCapture(0)
[*]
self.Bind(wx.EVT_IDLE, self.onIdle)
[*]
[*]
def onIdle(self, event):
[*]
img = cvQueryFrame(self.cap)
[*]
self.displayImage(img)
[*] event.RequestMore()
[*]
[*]
def displayImage(self, img, offset=(0,0)):
[*] bitmap = wx.BitmapFromBuffer(img.width, img.height, img.imageData)
[*]
dc = wx.ClientDC(self)
[*]
dc.DrawBitmap(bitmap, offset, offset, False)
[*]
[*]
if __name__=="__main__":
[*] app = wx.App()
[*] frame = MyFrame()
[*]
frame.Show(True)
[*] app.MainLoop()
import wx
from opencv.cv import *
from opencv.highgui import *
class MyFrame(wx.Frame):
def __init__(self):
wx.Frame.__init__(self, None, -1, 'camera')
self.SetClientSize((640, 480))
self.cap = cvCreateCameraCapture(0)
self.Bind(wx.EVT_IDLE, self.onIdle)
def onIdle(self, event):
img = cvQueryFrame(self.cap)
self.displayImage(img)
event.RequestMore()
def displayImage(self, img, offset=(0,0)):
bitmap = wx.BitmapFromBuffer(img.width, img.height, img.imageData)
dc = wx.ClientDC(self)
dc.DrawBitmap(bitmap, offset, offset, False)
if __name__=="__main__":
app = wx.App()
frame = MyFrame()
frame.Show(True)
app.MainLoop()
运行之
