The viewSet object and its updateView function will be removed in a future release. Use the imageviewset object and its updateView function instead. For more information, see Compatibility Considerations.

Description

vSet = updateView(vSet,viewId) modifies the view specified by viewId in the specified viewSet object, vSet.

example

vSet = updateView(vSet,viewId,Name,Value) specifies additional options using one or more name-value pair arguments.

vSet = updateView(vSet,views) modifies a view or a set of views specified by the view table.

Examples

collapse all

Create an empty viewSet object.

vSet = viewSet;

Detect interest points in the image.

imageDir = fullfile(toolboxdir('vision'),'visiondata','structureFromMotion');
I = imread(fullfile(imageDir,'image1.jpg'));
points = detectSURFFeatures(rgb2gray(I));

Add the points to the object.

vSet = addView(vSet,1,'Points',points);

Update the view to specify the camera pose.

vSet = updateView(vSet, 1,'Orientation',eye(3),'Location',[0,0,0]);

Input Arguments

collapse all

viewSet object.

Camera pose view ID in the viewSet object, specified as an integer.

Camera views, specified as a table. The table must contain a column named ViewID, and one or more columns named Points, Orientation, or Location.

Name-Value Arguments

Specify optional comma-separated pairs of Name,Value arguments. Name is the argument name and Value is the corresponding value. Name must appear inside quotes. You can specify several name and value pair arguments in any order as Name1,Value1,...,NameN,ValueN.

Example: Location, '[0,0,0]'

Image points, specified as the comma-separated pair consisting of 'Points' and an M-by-2 matrix of [x,y] coordinates or any points object.

Orientation of the second camera relative to the first camera, specified as the comma-separated pair consisting of 'Orientation' and a 3-by-3 matrix that represents the [x,y,z] orientation of the second camera.

Location of the second camera relative to the first camera, specified as the comma-separated pair consisting of 'Location' and a three-element vector that represents the [x,y,z] location of the second camera in the first camera’s coordinate system.
