using undistortImage() in Simulink under MATLAB Function

I have a Raspberry Pi attached to camera and I would like to perform camera calibration. I have the cameraParameters acquired through Camera Calibrator App. I can undistort the image in MATLAB with undistortImage() function. Can I use undistortImage() in Simulink at all? If yes, my cameraParameters would a parameter to a MATLAB function block in Simulink. How do make sure that Simulink can read the CameraParameter?

edit: Just found out using undistortImage in MATLAB Function block is not possible. How can I calibrate images in Simulink?

Hi,

I understand that you want to undistort an image in Simulink and calibrate them.

Even though you cannot directly use the 'undistortImage()' function within a MATLAB Function block in Simulink, you can still perform image undistortion in Simulink using the Computer Vision Toolbox. The toolbox provides blocks for camera calibration and undistortion that you can use in a Simulink model.

Refer to the following MathWorks documentations to know more about the same:

• Image Undistortion: https://www.mathworks.com/help/visionhdl/ug/image-undistort.html
• Camera Caliberation: https://www.mathworks.com/help/vision/ug/camera-calibration.html#bu0nj3f

I hope this resolves your issue.
