Currently you cannot save the images with detected edges in the Camera Calibrator App.
As a workaround, you can use detectCheckerboardPoints function to detect checkerboard pattern in image and use the saveas function to save the image with marked edges.
You can refer to the following demo code:
%% Read inbuilt checkerboard image
imageFileName = "image3.tif";
imageFilePath = fullfile(matlabroot,'toolbox','vision',...
'visiondata','calibration','webcam',imageFileName);
I = imread(imageFilePath);
%% Detect calibration pattern in the images.
[imagePoints,boardSize,imagesUsed] = detectCheckerboardPoints(I);
%% Display the image
fig = figure;
imshow(I);
hold on;
%% Display (superimpose) the detected points
plot(imagePoints(:,1),imagePoints(:,2),'go','MarkerSize',12);
%% Save the edge marked image to a file
saveas(fig,'detectedCheckerboardPoints.tif');
You can process all of the calibration images in a similar manner.
