MATLAB: Camera angle from perspective

camerahomogeneous matrixperspectiveprojection

Hello! How can the camera angles calculated from the perspective distortion? If the corresponding points of the object (let's take a simple flat, rectangular object in the 3D space) and it's corresponding points in the camera image are known, how can be the angle under which the image was taken, calculated? I already calculated the homogeneous matrix, but I would need to know the angles.

MATLAB: Convert unorganized point cloud (MX3) to organized point cloud (MXNX3)

You do not need to convert a pointCloud to organized form to use the pcfitplane function.

Here is an example:

% Read an unorganized point cloud
ptCloud = pcread('teapot.ply');
% The point cloud is unorganized, since Location property is M-by-3
disp(size(ptCloud.Location))
% Use pcfitplane
maxDistance     = 0.5;
referenceVector = [0 0 1];
model = pcfitplane(ptCloud, maxDistance, referenceVector)
figure
pcshow(ptCloud)
hold on
plot(model)

If you are getting an error, could you please send reproduction steps and the release of MATLAB you are using (use the ver command).

MATLAB: I calibrated the camera using Camera Calibration app,How do i apply it to the camera for further use

If you click the "Export" button on the app, it will export a cameraParameters object to your workspace. There is a variety of functions that use it, such as undistortImage, cameraMatrix, and cameraPose.
