I need to specify camera Intrinsics.
For this i wrote:
KameraInnereien=cameraIntrinsics(‘focalLength’,[0 0] ,’ImageSize’,[1440 2560],’PrincipalPoint’,[720 1280]);
When executing i get the Error:
Error using cameraIntrinsics
Expected abcd to be one of these types:
double, single

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Looking into the function that throws the Error shows the variable ‘abcd’, (which is kinda weird it looks like a Placeholder):
function r = parseInputsSimulation(defaultParams,varargin)

parser = inputParser;
focalLength = varargin{1};
validateattributes(focalLength, {‘double’, ‘single’}, …
{‘vector’,’real’, ‘nonsparse’, ‘finite’, ‘positive’}, …
‘cameraIntrinsics’, ‘abcd’);

filename = ‘cameraIntrinsics’;
parser.addRequired(‘focalLength’, @(f)vision.internal.inputValidation.validateFocalLength(f,filename));
parser.addRequired(‘principalPoint’, @(p)vision.internal.inputValidation.validatePrincipalPoint(p,filename));
parser.addRequired(‘imageSize’, @(sz)vision.internal.inputValidation.validateImageSize(sz,filename));

parser.addParameter(‘RadialDistortion’, defaultParams.RadialDistortion, …
@vision.internal.calibration.CameraParametersImpl.checkRadialDistortion);
parser.addParameter(‘TangentialDistortion’, defaultParams.TangentialDistortion,…
@vision.internal.calibration.CameraParametersImpl.checkTangentialDistortion);

parser.addParameter(‘Skew’, defaultParams.Skew, @cameraIntrinsics.checkSkew);

% Parse and check optional parameters
parser.parse(varargin{:});
r = parser.Results;
end
What shall i do to avoid it, i tried declaring abcd when calling cameraIntrinsics, but obviously that did not work.
KameraInnereien=cameraIntrinsics(‘abcd’,1 ,’focalLength’,[0 0] ,’ImageSize’,[1440 2560],’PrincipalPoint’,[720 1280]);
Doing it with string Names " " instead of char ‘ ‘ does obviously not change the outcome.
Is abcd a Placeholder that is not implemented right or is the error on my part?I need to specify camera Intrinsics.
