我有一個Raspberry Pi相機版本v2.1,能夠拍攝3280x2464分辨率的圖片。Python沒有以最高分辨率從Raspberry Pi Camera拍攝
我已與raspistill命令測試,這似乎很好地工作了:
raspistill -o 8mp.png -w 3280 -h 2464
返回信息:
8mp.png JPEG 3280x2464 3280x2464+0+0 8-bit sRGB 4.524MB 0.010u 0:00.010
然而,當我使用Python代碼取圖片,它會拒絕它。這裏是我正在使用的代碼:
#!/usr/bin/python
import picamera
camera = picamera.PiCamera()
camera.resolution = (3280,2464)
camera.capture("test.png")
camera.close()
這是錯誤:
mmal: mmal_vc_port_enable: failed to enable port vc.ril.image_encode:out:0(PNG): ENOSPC
mmal: mmal_port_enable: failed to enable port vc.ril.image_encode:out:0(PNG)(0x700090) (ENOSPC)
Traceback (most recent call last):
File "pic.py", line 6, in <module>
camera.capture("test.png")
File "/usr/local/lib/python2.7/dist-packages/picamera/camera.py", line 1383, in capture

super(PiCookedOneImageEncoder, self).start(output)

raise PiCameraMMALError(status, prefix)
picamera.exc.PiCameraMMALError: Unable to enable port vc.ril.image_encode:out:0(PNG): Out of resources (other than memory)
我已經注意到以.jpg,而不是巴紐將努力這樣做。這對我來說似乎有點奇怪,因爲文檔說它應該工作,raspistill命令也適用於.png上的這個分辨率。
任何想法?
如何查看picamera(https://picamera.readthedocs.io/en/release-1.12/)庫? –
正如我前面提到的,我已經看過文檔,它特別提到PNG的工作原理。 – user5740843
