findView

Find views associated with view identifiers

Since R2021b

Syntax

views = findView(vSet,viewIds)

Description

views = findView(vSet,viewIds) returns a table containing view attributes that correspond to the view identifiers in viewIds.

Examples

Find View Corresponding to View ID

Create an empty point cloud view set.

vSet = pcviewset;

Add two views to the view set.

viewId1 = 10;
viewId2 = 5;
ptCloud1 = pcread("teapot.ply");
ptCloud2 = pctransform(ptCloud1,rigidtform3d([0 0 0],[2 0 0]));
vSet = addView(vSet,viewId1,PointCloud=ptCloud1);
vSet = addView(vSet,viewId2,PointCloud=ptCloud2);

Find the view associated with the view identifier 5, and then display the view table.

view = findView(vSet,5);    
disp(view)

    ViewId      AbsolutePose        PointCloud  
    ______    ________________    ______________

      5       1×1 rigidtform3d    1×1 pointCloud

Get the point cloud that corresponds to view identifier 5.

ptCloud = view.PointCloud;

Get the absolute pose associated with view identifier 5.

absPose = view.AbsolutePose;

Input Arguments

vSet — Point cloud view set

pcviewset object

Point cloud view set, specified as a pcviewset object.

viewIds — View identifier

M-element vector

View identifiers, specified as an M-element vector of integers. View identifiers are unique to a specific view.

Output Arguments

views — Table containing view attributes

three-column table

Table containing view attributes, specified as a three-column table. The table contains the columns ViewId, AbsolutePose, and pointCloud attribute descriptions.
