Hi!
I’m trying to capture image from a raspberry pi camera (CSI) and upload the image to my google drive automatically by using crontab.
My code works fine when I run it in terminal, and also work fine with just uploading an existing file to google drive by using crontab. However, it only failed when I tried to capture image using crontab or systemd.
I’ve been trying many methods, but it still not work at all.
Here is my python file:
import cv2
import time
from pydrive.auth import GoogleAuth
from pydrive.drive import GoogleDrive
gauth = GoogleAuth()
gauth.LoadCredentialsFile("mycreds.txt")
if gauth.credentials is None:
gauth.LocalWebserverAuth()
elif gauth.access_token_expired:
gauth.Refresh()
else:
gauth.Authorize()
gauth.SaveCredentialsFile("mycreds.txt")
def gstreamer_pipeline(
capture_width=1280,
capture_height=720,
display_width=1280,
display_height=720,
framerate=60,
flip_method=0,
):
return (
"nvarguscamerasrc ! "
"video/x-raw(memory:NVMM), "
"width=(int)%d, height=(int)%d, "
"format=(string)NV12, framerate=(fraction)%d/1 ! "
"nvvidconv flip-method=%d ! "
"video/x-raw, width=(int)%d, height=(int)%d, format=(string)BGRx ! "
"videoconvert ! "
"video/x-raw, format=(string)BGR ! appsink"
% (
capture_width,
capture_height,
framerate,
flip_method,
display_width,
display_height,
)
)
def show_camera(new_path):
print(gstreamer_pipeline(flip_method=0))
cap = cv2.VideoCapture(gstreamer_pipeline(flip_method=0), cv2.CAP_GSTREAMER)
if cap.isOpened():
window_handle = cv2.namedWindow("CSI Camera", cv2.WINDOW_AUTOSIZE)
# Window
while cv2.getWindowProperty("CSI Camera", 0) >= 0:
ret_val, img = cap.read()
cv2.imwrite(new_path, img)
break
cap.release()
cv2.destroyAllWindows()
else:
print("Unable to open camera")
if __name__ == "__main__":
now_str = time.localtime()
new_path = str(now_str.tm_year) + str(now_str.tm_mon) + str(now_str.tm_mday) + str(now_str.tm_hour) + str(now_str.tm_min) + '.png'
show_camera(new_path)
upload_drive(new_path)
And this is my code in crontab -e:
* * * * * cd desktop/image_temp && /usr/bin/python3.6 test_cam_path.py >> test_cam_path.out
And this is the content in test_cam.out:
