implementation of some basic algorithms for point cloud orientation:
7
- Implementation of rigid registration algorithm which searches transformation
8
form one point cloud to another assuming that points in this clouds are
9
already paired (points with the same index in different clouds belongs to
10
the same pair) which minimizes average distance between points in pairs.
12
Algorithm uses Levenberg-Marquardt solver to find such transformation.
14
Supports registration of rotation-scale-transform (which is probably most
15
common usage) and rotation only (which might be useful for basic modal
18
- Implementation of Iterative-Point-Clouds algorithm which searches
19
transformation from one arbitrary point cloud to another making
20
points as closest to each other as possible.
22
This algorithm doesn't require points be initially paired, but for
23
good result clouds should have rough initial orientation. If they're
24
arbitrary oriented from the very beginning, algorithm might fail
25
producing good resold.
27
Iteration is based on building pairs of closest to each other points
28
and registering rigid transformation between them which incrementally
29
constructs final result.
31
TODO: building pairs might be speedup a lot using data structures like
32
AABB trees, K-D trees or so.

47
- Deduplicate pattern sampling used in esm and lmicklt trackers
48
and move SamplePattern to image/sample.h
49
- Move computation of Pearson product-moment correlation into
50
own function in new file image/correlation.h so all trackers
51
can use it to check final correlation.
52
- Remove SAD tracker. It's almost the same as brute tracker,
53
with only two differences:
54
1. It does brute search of affine transformation which in some cases
55
helps to track rotating features
56
2. It didn't use common tracker api which probably gave some speed
57
advantage, but lead to a real headache to use it together with
58
other trackers leading to duplicated code in 3d-party software.

Replace "third_party/glog/src/glog/logging.h" with <glog/logging.h>
75
It was needed because of how build systems is setup in Blender but think
76
this will be helpful change for other applications too because it makes
77
it's easier to move libraries around and even use libraries installed
78
on the operation system.

Upgrade gflags and glog libraries - stage 2 (final)
86
Changes to upstream code which are needed to make libmv compile smooth on all platforms
88
* Replace <gflags/gflags.h> with "third_party/gflags/gflags/gflags.h" which is easier
89
to setup things in libmv and also helps with setting up building libmv into
90
external applications.
91
* Replace "glog/logging.h" and "glog/logging.h" with <glog/logging.h> and <glog/logging.h>
92
which is needed on Windows platform because otherwise files like logging.cc will be using
93
relative path which points to headers used by linux instead of headers need to be used
95
* Replace _asm int 3 with __debugbreak(). Such assembler code is obsolete and doesn't work
96
with 64bit versions of MSVC compilers.
97
* Do not use stacktrace for MinGW and FreeBSD because it leads into issues accessing
98
some specific data on this platforms.
99
* Define HAVE_LIB_GFLAGS for Windows builds.
100
* Do not define __declspec(dllimport) for MinGW platforms.
101
* Setup proper includes and datatypes for int32, uint32, int64 and uint64 for MinGW
102
* Do not define va_copy for MinGW platforms (it's already defined there).
103
* Patch localtime_r to be working fine with MinGW, disable strerror_r for MinGW because
104
of lack of needed functions.

Upgrade gflags and glog libraries - stage 1
112
This commit copies sources from latest original release of gflags and glog
113
over currently bundled versions of this libraries without any modifications.
115
This revision can't b compiled, all needed changes to make new libraries working
116
fine will be done with next commit to make it clear which changes were necessary
117
for easier bundling further newer version and extract patches and put them to
118
gflags/glog upstream repo.
120
Such upgrade of libraries is needed to make it able to compile libmv
121
with clang compilers. Currently used versions:
123
- gflags is version 2.0
124
- glog is version 0.3.2

223
Add support for detecting tracking failure in the ESM tracker component of
224
libmv. Since both KLT and Hybrid rely on ESM underneath, KLT and Hybrid now
225
have a minimum correlation setting to match. With this fix, track failures
226
should get detected quicker, with the issue that sometimes the tracker will
227
give up too easily. That is fixable by reducing the required correlation (in
228
the track properties).

234
Add a new hybrid region tracker for motion tracking to libmv, and
235
add it as an option (under "Hybrid") in the tracking settings. The
236
region tracker is a combination of brute force tracking for coarse
237
alignment, then refinement with the ESM/KLT algorithm already in
238
libmv that gives excellent subpixel precision (typically 1/50'th
241
This also adds a new "brute force" region tracker which does a
242
brute force search through every pixel position in the destination
243
for the pattern in the first frame. It leverages SSE if available,
244
similar to the SAD tracker, to do this quickly. Currently it does
245
some unnecessary conversions to/from floating point that will get
248
The hybrid tracker glues the two trackers (brute & ESM) together
249
to get an overall better tracker. The algorithm is simple:
251
1. Track from frame 1 to frame 2 with the brute force tracker.
252
This tries every possible pixel position for the pattern from
253
frame 1 in frame 2. The position with the smallest
254
sum-of-absolute-differences is chosen. By definition, this
255
position is only accurate up to 1 pixel or so.
256
2. Using the result from 1, initialize a track with ESM. This does
257
a least-squares fit with subpixel precision.
258
3. If the ESM shift was more than 2 pixels, report failure.
259
4. If the ESM track shifted less than 2 pixels, then the track is
260
good and we're done. The rationale here is that if the
261
refinement stage shifts more than 1 pixel, then the brute force
262
result likely found some random position that's not a good fit.

Assorted camera tracker improvements
270
- Add support for refining the camera's intrinsic parameters
271
during a solve. Currently, refining supports only the following
272
combinations of intrinsic parameters:
280
This is not the same as autocalibration, since the user must
281
still make a reasonable initial guess about the focal length and
282
other parameters, whereas true autocalibration would eliminate
283
the need for the user specify intrinsic parameters at all.
285
However, the solver works well with only rough guesses for the
286
focal length, so perhaps full autocalibation is not that
289
Adding support for the last two combinations, (f, k1) and (f,
290
k1, k2) required changes to the library libmv depends on for
291
bundle adjustment, SSBA. These changes should get ported
292
upstream not just to libmv but to SSBA as well.
294
- Improved the region of convergence for bundle adjustment by
295
increasing the number of Levenberg-Marquardt iterations from 50
296
to 500. This way, the solver is able to crawl out of the bad
297
local minima it gets stuck in when changing from, for example,
298
bundling k1 and k2 to just k1 and resetting k2 to 0.
300
- Add several new region tracker implementations. A region tracker
301
is a libmv concept, which refers to tracking a template image
302
pattern through frames. The impact to end users is that tracking
303
should "just work better". I am reserving a more detailed
304
writeup, and maybe a paper, for later.
306
- Other libmv tweaks, such as detecting that a tracker is headed
307
outside of the image bounds.
309
This includes several changes made directly to the libmv extern
310
code rather expecting to get those changes through normal libmv
311
channels, because I, the libmv BDFL, decided it was faster to work
312
on libmv directly in Blender, then later reverse-port the libmv
313
changes from Blender back into libmv trunk. The interesting part
314
is that I added a full Levenberg-Marquardt loop to the region
315
tracking code, which should lead to a more stable solutions. I
316
also added a hacky implementation of "Efficient Second-Order
317
Minimization" for tracking, which works nicely. A more detailed
318
quantitative evaluation will follow.

330
Improve the KLT tracking behaviour and UI
332
- Remove the overly-conservative use of libmv's re-track tracker. The re-track
333
tracker would take a normal tracker such as TRKLT or KLT or pyramid KLT, and
334
track from frame 1 to 2, then back from the position found in 2 back to 1.
335
Then, when the reverse-track doesn't match the original track with high
336
precision, the track is considered "failed". This is a good approach for
337
fully automatic reconstruction, but is too conservative for supervised
340
The retrack-tracker will return when fully automatic tracking is added.
342
- Always solve for (dx, dy) in the TRKLT loop even if the linear system is
343
ill-conditioned. The client (Blender in this case) can still use the solved
344
position, even though it is less reliable.

Changes in camera intrinsics distortion/undistortion:
352
- Distortion/undistortion of scaled images wasn't happening right,
353
because camera intrinsics are calibrated on an original frame which
354
has got some particular resolution and trying to apply this model on
355
an image with another resolution gives totally wrong result.
356
This is needed to be able to do post-prccessing of render, running
357
distortion on a scene which might be rendered with higher resolution
358
than footage itself and then be scaled down.
359
- Fixed incorrect calculation/applying of precomputed grid when
360
distortion is high high enough and produces pixel offset higher
361
than 127 pixels. This might be still not very distorted image,
362
but if it's a 4K footage "normal" camera will easily give such
364
- Added support of overscan distortion/undistortion.
