updateConnection

(To be removed) Modify connection between two views in view set object

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

Description

vSet = updateConnection(vSet,viewId1,viewId2) modifies a connection between two views in the specified view set object, vSet.

example

vSet = updateConnection(vSet,viewId1,viewId2,Name,Value) specifies additional options using one or more name-value pair arguments. Unspecified arguments have default values.

Examples

collapse all

Create an empty viewSet object.

vSet = viewSet;

Read a pair of images.

imageDir = fullfile(toolboxdir('vision'),'visiondata','structureFromMotion');
I1 = rgb2gray(imread(fullfile(imageDir,'image1.jpg')));
I2 = rgb2gray(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.

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

Match features and store the matches.

indexPairs = matchFeatures(features1, features2);
vSet = addConnection(vSet,1,2,'Matches',indexPairs);

Update the connection to store a relative pose between the views.

vSet = updateConnection(vSet,1,2,'Orientation', eye(3),'Location',[1 0 0]);

Input Arguments

collapse all

viewSet object.

View ID 1 in the viewSet object, specified as an integer.

View ID 2 in the viewSet object, specified as an integer.

Name-Value Arguments

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

collapse all

viewSet object containing the modified connection.
