Motion detection using a raspberry pi camera
import numpy as np
import picamera
import picamera.array
class DetectMotion(picamera.array.PiMotionAnalysis):
def analyze(self, a):
a = np.sqrt(
np.square(a['x'].astype(np.float)) +
np.square(a['y'].astype(np.float))
).clip(0, 255).astype(np.uint8)
# If there're more than 10 vectors with a magnitude greater
# than 60, then say we've detected motion
if (a > 60).sum() > 10:
print('Motion detected!')
else:
print('No motion')
with picamera.PiCamera() as camera:
with DetectMotion(camera) as output:
camera.resolution = (640, 480)
camera.start_recording(
'/dev/null', format='h264', motion_output=output)
camera.wait_recording(5)
camera.stop_recording()
This is for a raspberry pi camera using a motion detection vector.
This code will record a 5-second video if it detects motion. My problem is I want to make this code camera.wait_recording(5) again if it is still detecting motion. Meaning if it detects motion the camera.wait_recording value will still be 5 seconds, and if it's not detecting motion the value of camera.wait_recording will start to decay.
