I'm using an OAK1 auto focus camera with an IMX378 sensor.
As I need full resolution images, I'm using Still images from the camera, but only getting around 10 FPS instead of 30 FPS (docs here).
Is there anything that I'm missing? How do I reach 30 FPS for full resolution sensor?
This is the minimal code to recreate it:
import datetime
import depthai as dai
pipeline = dai.Pipeline()
# Configure camera
cam_rgb = pipeline.createColorCamera()
cam_rgb.setResolution(dai.ColorCameraProperties.SensorResolution.THE_12_MP)
cam_rgb.setFps(30)
# Configure XLinkOut (to send data from device to host)
xout_rgb = pipeline.createXLinkOut()
xout_rgb.setStreamName('rgb')
# Script node
script = pipeline.create(dai.node.Script)
script.setScript('''
ctrl = CameraControl()
ctrl.setCaptureStill(True)
while True:
node.io['out'].send(ctrl)
''')
# Connections: Linking camera to XLink input, so that the frames will be sent to host
script.outputs['out'].link(cam_rgb.inputControl)
cam_rgb.still.link(xout_rgb.input)
with dai.Device(pipeline, maxUsbSpeed=dai.UsbSpeed.SUPER_PLUS) as device:
queue_rgb = device.getOutputQueue('rgb', maxSize=60, blocking=False)
tic = datetime.datetime.now()
while device.isPipelineRunning():
# Try to fetch data from queue. Returns either all data packets or None if there isn't any
queue_frames = queue_rgb.tryGetAll()
if len(queue_frames) > 0:
toc = datetime.datetime.now()
dt = (toc - tic)
fps = len(queue_frames) / dt.total_seconds()
print(f'Received {len(queue_frames)} frames in {str(dt)} --> Rate: {fps:.2f} fps')
tic = tocOutput:
