Hello
My problem is the following:
I'm using the oak-d pro w to record camera data segmentwise. what i need are 5 minute video segments for e time period of about 10 hours, To do so i wrote this code:
def record_segment(self) -> str:
with OakCamera() as camera:
camera.device
color = camera.create_camera(
"color", resolution="1080P", fps=20, encode="H265"
)
stereo = camera.create_stereo(resolution="800p", fps=20, encode="H264")
stereo.config_wls(wls_level="medium")
outputs = [color.out.encoded, stereo.out.disparity]
record = camera.record(
outputs,
str(get_output_path() / self.subfolder),
record_type=RecordType.VIDEO,
)
# create pipline for camera sensors and imu sensor
imu = camera.pipeline.create(dai.node.IMU)
xlinkOut = camera.pipeline.create(dai.node.XLinkOut)
xlinkOut.setStreamName("imu")
imu.enableIMUSensor(
[dai.IMUSensor.ACCELEROMETER_RAW, dai.IMUSensor.GYROSCOPE_RAW], 100
)
imu.setBatchReportThreshold(1)
imu.setMaxBatchReports(10)
imu.out.link(xlinkOut.input)
camera.start()
imu_out = camera.device.getOutputQueue(
name="imu", maxSize=50, blocking=False
)
start_time = time.monotonic()
# running until out of time
with open("imu.csv", "a", newline="") as file:
writer = csv.writer(file)
while camera.running():
# get imu data during the camera is running
self.write_imu_data(imu_out.get().packets, writer)
if not self.record_condition(time.monotonic() - start_time):
camera.device.close()
camera.poll()This function is called in a loop and records one segment. This all seems to work for some time but unfortunatly it breaks after one or two hours.
The error i get is X_LINK_DEVICE_NOT_FOUND. Even if i try to look up usb devices in linux (lsusb) i cant find the device. But if i reconnect it (plug in / plug out), it is found again.
In journalctl i see the following:
