[BUG] The issue of output image of OAK-1-W sensor with 400P resolution

[cjh1995-ros]

Describe the bug A clear and concise description of what the bug is. Currently, I'm working on OAK-1-W-97 with OV9782. In the doc, it supports 400P, 720P, 800P. So I try to test every resolution and 720P and 800P work fine, but 400P gave me the following result.

I tested it with following code.

import depthai as dai
import cv2

pipeline = dai.Pipeline()

# Define sources and outputs
camRgb: dai.node.Camera = pipeline.create(dai.node.Camera)

#Properties
camRgb.setBoardSocket(dai.CameraBoardSocket.CAM_A)
camRgb.setSize((640, 400))

# Linking
videoOut = pipeline.create(dai.node.XLinkOut)
videoOut.setStreamName("video")
camRgb.video.link(videoOut.input)

ispOut = pipeline.create(dai.node.XLinkOut)
ispOut.setStreamName("isp")
camRgb.isp.link(ispOut.input)

with dai.Device(pipeline) as device:
    video = device.getOutputQueue(name="video", maxSize=1, blocking=False)
    isp = device.getOutputQueue(name="isp", maxSize=1, blocking=False)

    while True:
        if video.has():
            cv2.imshow("video", video.get().getCvFrame())
        if isp.has():
            cv2.imshow("isp", isp.get().getCvFrame())
        if cv2.waitKey(1) == ord('q'):
            break

For additional test, here's the result of depthai-viewer. Idk why the following log came out.

[18443010C1D9E4F400] [3.3.2.1] [1.634] [ColorCamera(0)] [warning] Unsupported resolution set for detected camera OV9782, needs 800_P or 720_P. Defaulting to 800_P

I think the issue is that older calibrations store ov9782 as being able to output both mono and color: socket: CAM_A, sensorName: OV9782, width: 1280, height: 800, orientation: AUTO, supportedTypes: [COLOR, MONO]. We can fix it by changing the calibration or to fix in FW. cc @SzabolcsGergely

@jakaskerl So do I need to calibrate the camera with chessboard?

Hi @cjh1995-ros Afaik the device needs to be reflashed completely (not possible through recalibration). Best to wait for FW fix.

Workaround:

camRgb.setSize((1280, 800))
camRgb.setVideoSize((640, 400))

Thanks @jakaskerl. It worked!

Sorry that I closed the issue. I just checked and it works. However, fov is decreased so hard. Guess it cropped the undistorted image. Here's the results. Is there any way to resize the image in the Camera node?

(setSize - serVideoSize) 800P - 400P

800P - 800P

400P - 400P

@jakaskerl Then how long should I wait for the FW update?

@jakaskerl I meet the same question, how long will update the FW? many thanks
