  • In HFOV and VFOV angles

    Hello,

    I am interested in the OAK-4D Pro camera (wide variant). To ensure that the camera’s field of view is sufficient for our project, I would like to simulate the camera coverage. My question is: how can I calculate the HFOV and VFOV angles from the given DFOV of 120°? Alternatively, could you provide this information?

    Best regards,
    Fabian

      You're absolutely right; my initial reference was incorrect—I actually meant the MX50. Here you can see what schematic I have in front of me:

      Do you have also an answer to the question: Is there a way to control the onboard LED of the OAK-D SR PoE?

      • In GPIO Pin OAK-D SR PoE

        Hello Jaka

        Thank you for your response—using GPIO Pin 29 worked perfectly, and the toggling now occurs as expected on Pin 7 of the M8 AUX connector.

        However, I have a question: where can I find this information in the documentation? From the schematic on GitHub, it’s not clear to me that GPIO 29 corresponds to this pin.

        I also have one more question: is there a way to control the onboard LED of the OAK-D SR PoE?

        Thanks again for your help!

        • In GPIO Pin OAK-D SR PoE

          Hello everyone,

          I'm working with an OAK-D SR PoE camera and trying to control the GPIO pin available on the M8 AUX connector (specifically, Pin 7).

          In my opinion this pin should be controllable with GPIO-Pin-Number 30. Here's the test script I created:

          '''

          This Script purpose is to Test the functionality of the GPIO Pin of OAK-D SR PoE

          GPIO Pin is located at AUX M8-connector: Pin 7

          '''

          #!/usr/bin/env python3

          import depthai as dai

          import time

          # Create pipeline

          pipeline = dai.Pipeline()

          gpioScript = pipeline.create(dai.node.Script)

          # setting Properties of Script Node

          gpioScript.setProcessor(dai.ProcessorType.LEON_CSS)

          script_gpio_test = (f"""

          import GPIO

          import time


          GPIO_TEST_PIN = 30

          GPIO.setup(GPIO_TEST_PIN, GPIO.OUT, GPIO.PULL_DOWN)

          toggleVal = True

          while True:

          node.warn('GPIO toggle: ' + str(toggleVal))

toggleVal = not toggleVal

GPIO.write(GPIO_TEST_PIN, toggleVal)  # Toggle the GPIO

time.sleep(10)

          """

          )

          gpioScript.setScript(f"{script_gpio_test}")

          # Connect to device and start pipeline

          with dai.Device(pipeline) as device:

          device.setLogLevel(dai.LogLevel.DEBUG)

device.setLogOutputLevel(dai.LogLevel.DEBUG)

print('Connected to OAK')

while not device.isClosed():

    time.sleep(1)

          With this script, I expected Pin 7 on the M8 AUX connector to toggle every 10 seconds. However, the toggle is occurring on Pin 5 instead.

          Questions:

          • Am I misunderstanding the GPIO mapping for this device?

          • Could there be an error in the documentation, with the "GPIO 5V control signal" actually referring to Pin 5 on the M8 AUX connector instead of Pin 7?

          Any insights or similar experiences would be appreciated!
