[python]學習FFT

 照著網路文章打:

import numpy as np

import pylab as pl

sampling_rate=8000

fft_size=512

t=np.arange(0,1,1.0/sampling_rate)

x=np.sin(2*np.pi*156.25*t)+2*np.sin(2*np.pi*234.375*t)

xs=x[:fft_size]

xf=np.fft.rfft(xs)/fft_size

freqs=np.linspace(0,sampling_rate/2,fft_size/2+1)

xfp=20*np.log10(np.clip(np.abs(xf),1e-20,1e1000))

pl.figure(figsize=(8,4))

pl.subplot(211)

pl.plot(t[:fft_size],xs)

pl.xlabel(u"time(sec)")

pl.title(u"The Wave and Spectrum 156.25Hz 234.375Hz")

pl.subplot(212)

pl.plot(freqs,xfp)

pl.xlabel(u"Hz")

pl.subplots_adjust(hspace=0.4)

pl.show()

[python]攝影機檔案儲存

cap=cv2.VideoCapture(0)

#decode
fourcc=cv2.VideoWriter_fourcc('I', '4', '2', '0')

#image save
out=cv2.VideoWriter('out.avi',fourcc,20.0,(640,480))

while(cap.isOpened()):
    ret,frame=cap.read()
    if ret==True:
        out.write(frame)
        cv2.imshow('frame',frame)
        if cv2.waitKey(1)& 0xFF==ord('q'):
            break
    else:
        break

cap.release()
out.release()
cv2.destroyAllWindows()

[python]使用opencv 秀圖

在 visual studio ,安裝 opencv,必須在安裝 packeage 的搜尋地方打入 opencv-python 才行

簡單的程式:

import cv2
import numpy as np
import os
mywd="c:\pydata"
os.chdir(mywd)
cv2.namedWindow("test_show",1)
img=cv2.imread("1.jpg",1)
cv2.imshow("test_show",img)
cv2.waitKey(0)  ==>沒寫這欄,只會有框,不會秀圖........

成功!!!
