The viewSet object and its addConnection function will be removed in a future release. Use the imageviewset object and its addConnection function instead. For more information, see Version History.

Syntax

vSet = addConnection(vSet,viewId1,viewId2)
vSet = addConnection(vSet,viewId1,viewId2,Name,Value)

Description

vSet = addConnection(vSet,viewId1,viewId2) adds a connection between two views in the specified viewSet object, vSet.

vSet = addConnection(vSet,viewId1,viewId2,Name,Value) specifies additional options using one or more name-value pair arguments.

Examples

Open Live Script

Create an empty viewSet object.

vSet = viewSet;

Read a pair of images.

imageDir = fullfile(toolboxdir('vision'),'visiondata','structureFromMotion');
I1 = im2gray(imread(fullfile(imageDir,'image1.jpg')));
I2 = im2gray(imread(fullfile(imageDir,'image2.jpg')));

Detect interest points in the two images.

points1 = detectSURFFeatures(I1);
points2 = detectSURFFeatures(I2);

Add the points to the viewSet object.

vSet = addView(vSet,1,'Points',points1);
vSet = addView(vSet,2,'Points',points2);

Extract feature descriptors from both images.

features1 = extractFeatures(I1,points1);
features2 = extractFeatures(I2,points2);

Match features and store the matches.

indexPairs = matchFeatures(features1,features2);

Add the connection between the two views.

vSet = addConnection(vSet,1,2,'Matches',indexPairs);

Input Arguments

Name-Value Arguments

collapse all

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Before R2021a, use commas to separate each name and value, and enclose Name in quotes.

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

Indices of matched points between two views, specified as the comma-separated pair consisting of 'Matches' and an M-by-2 matrix.

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.

Output Arguments
