Package boofcv.alg.sfm.structure2

Class ProjectiveInitializeAllCommon

java.lang.Object

boofcv.alg.sfm.structure2.ProjectiveInitializeAllCommon

public class ProjectiveInitializeAllCommon
extends java.lang.Object

Given a set of views and a set of features which are visible in all views, estimate their structure up to a projective transform. Summary of processing steps:

1. Select initial set of 3 views
2. Association between all 3 views
3. RANSAC to find Trifocal Tensor
4. 3 Projective from trifocal
5. Triangulate features
6. Find remaining projective camera matrices
7. Refine with bundle adjustment

Must call if you change configurations.

projectiveSceneN

public boolean projectiveSceneN(LookupSimilarImages db,
                                PairwiseImageGraph2.View seed,
                                org.ddogleg.struct.GrowQueue_I32 seedFeatsIdx,
                                org.ddogleg.struct.GrowQueue_I32 seedConnIdx)

Computes a projective reconstruction. Reconstruction will be relative the 'seed' and only used features listed in 'common'. The list of views is taken from seed and is specified in 'motions'.

Parameters:

seed - The seed view that will act as the origin

seedFeatsIdx - Indexes of common features in the seed view which are to be used.

seedConnIdx - Indexes of motions in the seed view to use when initializing

Returns:

true is successful

projectiveCameras3

public boolean projectiveCameras3(LookupSimilarImages db,
                                  PairwiseImageGraph2.View viewA,
                                  int motionIdxB,
                                  int motionIdxC)

Computes projective camera matrices for the 3 connected views. No bundle adjustment or triangulation 1) Find features with continuous tracks across all 3 views 2) Robustly compute trifocal tensor 3) Extract compatible camera matrices

Parameters:

viewA - The origin view

motionIdxB - index on edge in viewA for viewB

motionIdxC - index on edge in viewA for viewC

Returns:

true is successful

setVerbose

public void setVerbose(java.io.PrintStream verbose,
                       int level)
