覆盆子看不到 USB 摄像头

  • 772

你好。我需要从连接到 python 覆盆子的 USB 相机获取照片。但事实是 PiCamera 标准库看不到相机，尽管它连接正确，我什至设法使用 luvcview 从中获取图像。问题是什么？追溯：

Traceback (most recent call last):
File "/home/pi/Desktop/cammm.py", line 4, in <module>
camera = picamera.PiCamera()
File "/usr/local/lib/python2.7/dist-packages/picamera/camera.py", line 431, 
in __init__
self._init_camera(camera_num, stereo_mode, stereo_decimate)
File "/usr/local/lib/python2.7/dist-packages/picamera/camera.py", line 460, 
 in _init_camera
 "Camera is not enabled. Try running 'sudo raspi-config' "
 picamera.exc.PiCameraError: Camera is not enabled. Try running 'sudo raspi- 
 config' and ensure that the camera has been enabled.

编码：

from time import sleep
from picamera import PiCamera

camera = picamera.PiCamera()
camera.resolution = (1024, 768)
camera.start_preview()
# Camera warm-up time
sleep(2)
camera.capture('foo.jpg')

    您可以尝试使用 pygame 捕获图像： 

    import pygame
import pygame.camera

pygame.camera.init()
cam = pygame.camera.Camera(0,(640,480))
cam.start()
img = cam.get_image()
pygame.image.save(img,"filename.jpg")
