findWorldPointsInTracks

Find world points that correspond to point tracks

Since R2020b

Syntax

pointIndices = findWorldPointsInTracks(wpSet,tracks)

[pointIndices,validIndex] = findWorldPointsInTracks(wpSet,tracks)

Description

pointIndices = findWorldPointsInTracks(wpSet,tracks) finds the indices of world points pointIndices that correspond to the specified point tracks tracks.

[pointIndices,validIndex] = findWorldPointsInTracks(wpSet,tracks) additionally returns a vector that indicates whether each point track has a corresponding world point.

Examples

Find World Points in Tracks

Load precomputed world point set and image view set.

data = load(fullfile(toolboxdir('vision'),'visiondata','worldpointsetAndTracks.mat'));

Find point tracks across views.

tracks = findTracks(data.vSet);

Find 3-D world points corresponding to point tracks.

pointIndices = findWorldPointsInTracks(data.wpSet,tracks);

Input Arguments

wpSet — World point set

worldpointset object

World point set, specified as a worldpointset object.

tracks — Point tracks

M-element row vector of pointTrack objects

Point tracks, specified as an M-element row vector of pointTrack objects.

Output Arguments

pointIndices — 3-D world point indices

N-element column vector

3-D world point indices, returned as an N-element column vector. N is the number of world points for which the function detects corresponding point tracks.

validIndex — Logical index

M-element logical vector

Logical index of point track correspondences, returned as an M-element logical vector. M is the number of point tracks in the tracks argument. A value of 1 (true) indicates that the associated point track has a corresponding world point, and a value of 0 (false) indicates that it does not.
