about DistortionCorrection for Bayer color camera

  • Hello,


    I want to check if there is any possibility of implementation.

    implementation : DistortionCorrection for bayer color camera.


    Target H/W : VQ4-GE

    Camera : Bayer Color Camera (4096x3000)


    Thanks.

    Best regards.

  • Hello Sangrae Kim


    you will need to do the De-Bayer before the distortion correction. So your bandwidth will get 3 times higher.

    An implementation on VQ4-GE is possible but the bandwidth might be limited. So it totally depends on the bandwidth requirements and the distortion factor. i.e. several pixel of just between 0 and 2 pixel.

  • Dear Sangrae Kim,

    under "\examples\Processing\Geometry\GeometricTransformation\DistortionCorrection.va" in your VisualApplets installation directory you can find an example for distortion correction implementation. This example is based on the OpenCV implementation for the determination for the correction coefficients. Please find a detailed description on this example under https://docs.baslerweb.com/liv…l#Distortion%20Correction.

  • Dear Johannes , Carmen


    Thank you for your advice.

    In the case of Mono camera, I tested it using a basic example.

    I don't know if it is possible to implement the basic algorithm for color cameras until the customer meeting.

    I will try it.


    Best regards.
