Unable to install depthai==2.15.4.0.dev+7ce594fa6a2b8437be7fef010a26b1eb5eb1fdf8 on Windows 10

[rexn8r]

Hello

I have been trying to install following depthai version on Windows 10 but it throws CMAKE errors.

python -m pip install -U --prefer-binary --user --extra-index-url https://artifacts.luxonis.com/artifactory/luxonis-python-snapshot-local "depthai==2.15.4.0.dev+7ce594fa6a2b8437be7fef010a26b1eb5eb1fdf8"

I followed manual installation steps provided on the following link on a fresh windows 10 system;

https://docs.luxonis.com/projects/api/en/latest/install/#windows-10

I also added C:\Program Files\CMake\Bin folder in the "Path" section in the environment variables.

The reason to install version depthai==2.15.4.0.dev+7ce594fa6a2b8437be7fef010a26b1eb5eb1fdf8 is that I am trying to implement -90 degree camera rotation.

please help to solve the problem

thanks rex

Hi @rexn8r , Which demo requires you to use the custom 2.15.4 branch/build? Thanks, Erik

Hi @Erol444

I am using oak-d camera with -90 degree rotation for age and gender

https://github.com/luxonis/depthai-experiments/issues/326#issuecomment-1124301011

This PR was provided by @szabi-luxonis

If I use the latest 2.19 release, the age and gender inferences are wrong with -90 degree rotation.

I am trying to install this PR on windows 10 but getting "failed building wheel" error despite installing CMake library, adding CMake path in the environment variables, and also installing c++ for CMake via visual studio build tools set up.

Do i need to install visual studio build tools first and then execute manual depthai installation commands in the windows powershell?

Thanks

Ok so found solution.

Installed Python 3.8

Installed CMake 3.21.2

Installed Visual Studio build tools 2017

now I can install depthai 2.15.4.0.dev+7ce594fa6a2b8437be7fef010a26b1eb5eb1fdf8

The reason I am using 2.15 dev pr is that, With depthai latest 2.19 release, if I rotate the camera to -90 degrees, the Z value coming out wrong.

MRE:

monoLeft = pipeline.create(dai.node.MonoCamera) monoLeft.setResolution(dai.MonoCameraProperties.SensorResolution.THE_400_P) monoLeft.setBoardSocket(dai.CameraBoardSocket.LEFT)

monoRight = pipeline.create(dai.node.MonoCamera) monoRight.setResolution(dai.MonoCameraProperties.SensorResolution.THE_400_P) monoRight.setBoardSocket(dai.CameraBoardSocket.RIGHT)

stereo = pipeline.create(dai.node.StereoDepth) stereo.setDefaultProfilePreset(dai.node.StereoDepth.PresetMode.HIGH_DENSITY) stereo.setLeftRightCheck(True) stereo.setDepthAlign(dai.CameraBoardSocket.RGB) stereo.setOutputSize(monoLeft.getResolutionWidth(), monoLeft.getResolutionHeight()) stereo.setExtendedDisparity(True) stereo.setSubpixel(False)

manipLeft = pipeline.create(dai.node.ImageManip) rrL = dai.RotatedRect() rrL.center.x, rrL.center.y = monoLeft.getResolutionWidth() // 2, monoLeft.getResolutionHeight() // 2 rrL.size.width, rrL.size.height = monoLeft.getResolutionHeight(), monoLeft.getResolutionWidth() rrL.angle = -90 manipLeft.initialConfig.setCropRotatedRect(rrL, False) manipLeft.inputConfig.setWaitForMessage(False) monoLeft.out.link(manipLeft.inputImage)

manipRight = pipeline.create(dai.node.ImageManip) rrL = dai.RotatedRect() rrL.center.x, rrL.center.y = monoRight.getResolutionWidth() // 2, monoRight.getResolutionHeight() // 2 rrL.size.width, rrL.size.height = monoRight.getResolutionHeight(), monoRight.getResolutionWidth() rrL.angle = -90 manipRight.initialConfig.setCropRotatedRect(rrL, False) manipRight.inputConfig.setWaitForMessage(False) monoRight.out.link(manipRight.inputImage)

monoLeft.out.link(stereo.left) monoRight.out.link(stereo.right)

thanks rex

hello

any thoughts on -90 degree rotation not working with 2.19??

thanks

[Erol444]

Hi @rexn8r ,

the Z value coming out wrong.

Could you provide screenshots that would showcase this, like szabi did in the comments? Thanks, Erik

[rexn8r]

hello @Erol444

please check following screenshots. the script is using depthai version 2.20.1.0

As you can see, the Z value comes out similar whether i am closer to the camera or far away.

thanks

@rexn8r at the moment rotated frames are not supported, but we are planning to add support to latest depthai version. For now you need to use that specific depthai version for your use case.

Ok thanks
