MATLAB: Are campos and view interlocked?

cameracamposview

Hi everyone,

I've been playing around with these two parameters for an hour and it seems whenever you change one of them, the other will change automatically. What I want to do is to have the camera positioned at say [1,1,1] and have it viewing along the x-axis (i.e. a line parallel to the x-axis which passes through [1,1,1]). Does anyone know if there is a way to do that? Thanks a lot!!

Niko

Set the axes CameraPosition and CameraTarget properties?

You need to use the axes of the pcplayer object.

For example,

% Create a pcplayer viewer
player = pcplayer([0 1], [0 1], [0 1]);
% View a point cloud
view(player, rand(1000,3));
% Query camera view angle
camva(player.Axes)
% Set camera view angle
camva(player.Axes, 15)

MATLAB: Is the pointsToWorld back-projection inverted

You may need to convert the camera world pose to extrinsics using cameraPoseToExtrinsics:

[worldOri,worldLoc] = estimateWorldCameraPose(worldPoints(:,[1 2]),worldPoints,intrinsics);
[rotationMatrix,translationVector] = cameraPoseToExtrinsics(worldOri,worldLoc);
backProjectPoints = pointsToWorld(intrinsics,rotationMatrix,translationVector,imagePoints);
