Rotate camera by 90 DEGREES

Hello ramkunchur,
the colorCamera doesn't have out output, you should use preview instead. Please refer to our documentation for more information. I just tried it out with color camera instead of mono but it doesn't seem like it's working correctly (code here). We are investigating this further and it should be fixed this week, we apologize for the inconvenience.
Thanks, Erik

Hello ramkunchur ,
sorry for the troubles, it turns out I was incorrect - rotating color frames is already available, the width of the (input) frame just has to be in multiples of 16. Here's a minimal example code.
Thanks, Erik

Hello ramkunchur,
here I quickly prepared a minimal solution to achieve that. It uses another ImageManip to crop the frame into 300x300. You could also use cropping on the first imageManip, but for some reason, the output frame doesn't keep its aspect ratio (it gets stretched).
Thanks, Erik

ramkunchur just tried it again; works as expected. I have depthai version 2.8 (in case you have an older version where it potentially doesn't work). What is the output of the program?
Thanks, Erik

It looks like you'll need to use ImageManip to crop and or "squeeze" the 640x400 resolution you have to the 300x300 resolution of the neural network.

Thoughts?

Thanks,
Brandon

ramkunchur yes, that's the correct code. I have created another demo code that links 300x300 rotated frames to mobilenet. You will need to place this script into depthai-python/examples, as it requires mobilenet blob. Unfortunately, I don't have time to update the script you mentioned, but I am sure you will be able to update it yourself with the help of the demo script I have just created - it should be straightforward.
Thanks, Erik

ramkunchur You could just use cv2.resize() function to upscale the 300x300 frame to the desired size. You could also stream 1080P video output to the device and display detections on the video frames - not 300x300 preview frame. So something similar to this example.
Thanks, Erik

Hello All,

I am trying to rotate my camera but I am confused by the links and syntax of this api and I need this done very soon for production. Here is my code:

def get_pipeline():
    pipeline = dai.Pipeline()

    # # Define a source - color camera
    cam = pipeline.createColorCamera()
    cam.setBoardSocket(dai.CameraBoardSocket.RGB)
    # cam.setInterleaved(False)
    cam.setResolution(dai.ColorCameraProperties.SensorResolution.THE_48_MP)
    cam.setVideoSize(1920, 1080)
    cam.initialControl.setSceneMode(dai.CameraControl.SceneMode.FACE_PRIORITY)

    # Create MobileNet detection network
    mobilenet = pipeline.create(dai.node.MobileNetDetectionNetwork)
    mobilenet.setBlobPath(
        blobconverter.from_zoo(name="face-detection-retail-0004", shaves=3)
    )
    mobilenet.setConfidenceThreshold(0.7)

    crop_manip = pipeline.create(dai.node.ImageManip)
    crop_manip.initialConfig.setResize(300, 300)
    crop_manip.initialConfig.setFrameType(dai.ImgFrame.Type.BGR888p)
    cam.isp.link(crop_manip.inputImage)
    crop_manip.out.link(mobilenet.input)

    # Create an UVC (USB Video Class) output node. It needs 1920x1080, NV12 input
    uvc = pipeline.createUVC()
    cam.video.link(uvc.input)

This is what I tried but I am just guessing.

def get_pipeline():
pipeline = dai.Pipeline()

    # # Define a source - color camera
    cam = pipeline.createColorCamera()
    cam.setBoardSocket(dai.CameraBoardSocket.RGB)
    # cam.setInterleaved(False)
    cam.setResolution(dai.ColorCameraProperties.SensorResolution.THE_48_MP)
    cam.setVideoSize(1920, 1080)
    cam.initialControl.setSceneMode(dai.CameraControl.SceneMode.FACE_PRIORITY)

    # Create MobileNet detection network
    mobilenet = pipeline.create(dai.node.MobileNetDetectionNetwork)
    mobilenet.setBlobPath(
        blobconverter.from_zoo(name="face-detection-retail-0004", shaves=3)
    )
    mobilenet.setConfidenceThreshold(0.7)

    #

    manipRgb = pipeline.createImageManip()
    rgbRr = dai.RotatedRect()
    rgbRr.center.x, rgbRr.center.y = cam.getPreviewWidth() // 2, cam.getPreviewHeight() // 2
    rgbRr.size.width, rgbRr.size.height = cam.getPreviewHeight(), cam.getPreviewWidth()
    rgbRr.angle = 90
    manipRgb.initialConfig.setCropRotatedRect(rgbRr, False)
    cam.preview.link(manipRgb.inputImage)


    #

    crop_manip = pipeline.create(dai.node.ImageManip)
    crop_manip.initialConfig.setResize(300, 300)
    crop_manip.initialConfig.setFrameType(dai.ImgFrame.Type.BGR888p)
    manipRgb.out.link(crop_manip.inputImage) #added
    cam.isp.link(crop_manip.inputImage)
    crop_manip.out.link(mobilenet.input)

Hi chandrian ,
Please see how to prepare MRE here so we can help you.
Thanks, Erik

We're those guidelines for posting to the forum or submitting for review?
We are using a UVC and I was trying to flip the image before output but I think it needs to be 1920,1080 so it is faulting.. Is it possible to rotate the image from a script?
