pointTrack

Object for storing matching points from multiple views

Description

Use this object to store 2-D points in an image that match across multiple views of the same image.

Creation

track = pointTrack(viewIDs,points)

Description

track = pointTrack(viewIDs,points) returns an object that stores matching 2-D points from multiple views. You can also create this point track object using the findTracks object function of the imageviewset object.

Input Arguments

viewIDs — View IDs of image poses

M-element vector

View IDs of image poses, specified as an M-element vector of scalar integers.

points — 2-D points that match across multiple image views

M-by-2 matrix

2-D points that match across multiple image views, specified as an M-by-2 matrix of (x,y) point coordinates. You can use the matchFeatures function to find these points, and then save them using this object.

Output Arguments

track — Point track object

pointTrack object

Point track object, returned as a pointTrack object. You can use this object to store matching 2-D points from multiple views. You can also create this point track object using the findTracks object function of the imageviewset object.

Examples

Create a Point Track Object

Save ( x , y ) points and view IDs.

points = [10,20;11,21;12,22];
viewIDs = [1 2 3];

Create a pointTrack object to save points and IDs. The matched 2-D image points correspond to the same 3-D world point. Separate pointTrack objects are needed to track different 3-D world points across views.

track = pointTrack(viewIDs,points);
