Syntax

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

Description

example

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

example

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

Examples

collapse all

Open Live Script

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

collapse all

World point set, specified as aworldpointsetobject.

Point tracks, specified as anM-element row vector ofpointTrack对象.

Output Arguments

collapse all

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

Logical index of point track correspondences, returned as anM-element logical vector.Mis the number of point tracks in thetracksargument. A value of1(true) indicates that the associated point track has a corresponding world point, and a value of0(false) indicates that it does not.
