Frank Dellaert 99db4c37d8 2D Pose SLAM: created a new templated factor to accommodate GPS measurements, and as part of the refactor I consolidated all Pose2 SLAM classes in pose2SLAM.h. For backwards compatibility it contains
typedef pose2SLAM::Prior Pose2Prior;
	typedef pose2SLAM::Odometry Pose2Factor;
	typedef pose2SLAM::Constraint Pose2Constraint;
	typedef pose2SLAM::Config Pose2Config;
	typedef pose2SLAM::Graph Pose2Graph;

Richard Roberts ac10c440e1 PairConfig is implemented, VSLAMConfig is now a typedef! 2010-01-14 02:58:29 +00:00
Frank Dellaert 6b3e8cf49c simulated2D now reduced to one .h and .cpp, in its own namespace, better naming, and new-style functions to serve as example 2010-01-14 02:50:06 +00:00
Frank Dellaert 93465945e9 Large gtsam refactoring
To support faster development *and* better performance Richard and I pushed through a large refactoring of NonlinearFactors.

The following are the biggest changes:

1) NonLinearFactor1 and NonLinearFactor2 are now templated on Config, Key type, and X type, where X is the argument to the measurement function.

2) The measurement itself is no longer kept in the nonlinear factor. Instead, a derived class (see testVSLAMFactor, testNonlinearEquality, testPose3Factor etc...) has to implement a function to compute the errors, "evaluateErrors". Instead of (h(x)-z), it needs to return (z-h(x)), so Ax-b is an approximation of the error. IMPORTANT: evaluateErrors needs - if asked - *combine* the calculation of the function value h(x) and the derivatives dh(x)/dx. This was a major performance issue. To do this, boost::optional<Matrix&> arguments are provided, and tin EvaluateErrors you just  says something like

	if (H) *H = Matrix_(3,6,....);

3) We are no longer using int or strings for nonlinear factors. Instead, the preferred key type is now Symbol, defined in Key.h. This is both fast and cool: you can construct it from an int, and cast it to a strong. It also does type checking: a Symbol<Pose3,'x'> will not match a Symbol<Pose2,'x'>

4) minor: take a look at LieConfig.h: it help you avoid writing a lot of code bu automatically creating configs for a certain type. See e.g. Pose3Config.h. A "double" LieConfig is on the way - Thanks Richard and Manohar !
2010-01-13 22:25:03 +00:00
Kai Ni 4369cd2d92 1) add a compose function that compose all the poses in a factor graph given the spanning tree
2) add a new graph-inl.h which takes care of all the boost graph related functions to prevent the copy and paste across several classes

Richard Roberts 88ae5380a8 Removed Vector-specific versions of NumericalDerivative, instead Vector is now a Lie object 2010-01-10 18:23:47 +00:00
Frank Dellaert 1a96ef41cf Created Pose3Config, Pose3Graph, and tested loop closure optimization. 2010-01-10 18:21:20 +00:00

Richard Roberts 4fa53a1f79 Merging lieconfig branch - LieConfig works but currently requires Lie objects to have a global print function. 2010-01-10 06:35:16 +00:00
Richard Roberts 2b82ff65e7 Deriving Lie objects from a base class Lie<T>, which provides member functions to access global functions, for use in MATLAB. 2010-01-09 23:15:06 +00:00
Frank Dellaert 5dc237eeea BetweenFactor is a template that models the measurement between two Lie types e.g. Pose2 or Pose3. Pose2Factor and Pose3Factor are now simply typedefs. 2010-01-08 15:32:45 +00:00
Richard Roberts 19a3e228d7 Large refactoring - made several Lie group functions global, which used to be member functions, to treat Lie groups more uniformly. Also created Lie.h, and a preprocessor flag in numericalDerivative to change the coordinate frame derivatives are reported in. gtsam and easylib build and pass unit tests, but this will probably break other projects, which will require a few small changes to work again. Email coming in a few minutes to describe the changes. 2010-01-08 00:40:17 +00:00

Michael Kaess 72ba1bee24 separate cpp 2009-12-09 22:02:50 +00:00
Frank Dellaert 7d4de3ec20 Added a 1D manifold implementation of 2D rotations. The new representation stores (cos theta, sin theta) rather than theta itself, ensuring that (a) rotate and unrotate do not call cos/sin, (b) same for all derivatives of rotate and unrotate, (c) when you call angle(), you always get the standardized answer given by atan2. The idea is that we will use this new type in Pose2 instead of angle. 2009-12-09 21:50:27 +00:00

Alex Cunningham 107c6846fb Added basic inequality constraint handling to NonlinearConstraint. Demo still in progress, but now constraints are explicitly handled as either equality or inequality constraints, with an active() function to determine if it is necessary to use the constraint.
Created testOrdering for new subtract() function to remove parts of an ordering.
2009-11-28 18:35:36 +00:00
Alex Cunningham cf6474c99b Added a graph implementation for multi-robot control systems. Currently can only really constrain the ends of a trajectory.
Made a number of fixes and updates to the ControlConfig as well.
2009-11-27 17:59:03 +00:00
Alex Cunningham 2a2e11d05d Added the config and units for a robot control system example that keeps a position and velocity model of a robot's motion. 2009-11-26 05:52:17 +00:00
Alex Cunningham d788e9833d Added tests to ensure that configs will only update existing values when using exmap and not add new ones if there are more values in the delta config. VectorConfig and VSLAMConfig both do this properly now. 2009-11-24 15:12:59 +00:00
Alex Cunningham 0b333630e7 Added an SQPOptimizer class with accompanying test - currently doesn't do much 2009-11-23 19:57:35 +00:00

Alex Cunningham ee4a066275 Implemented linearization and equality for unary NonlinearConstraints. Current tests use a scalar example. Split out implementation into a separate implementation file. 2009-11-20 03:04:49 +00:00
Alex Cunningham 429f27550c Added a NonlinearConstraint and testNonlinearConstraint. There is currently an abstract base class for constraints and a partially implemented unary constraint. 2009-11-19 16:50:18 +00:00
Alex Cunningham f98f49381a Added an example to testSQP to use for combining graphs 2009-11-18 21:57:59 +00:00

Alex Cunningham 20830a1534 Added testSQP demo to show a simple problem solved by Sequential Quadratic Programming. To see the outputs, set verbose=true at the start of the test. 2009-11-16 19:12:56 +00:00
Alex Cunningham 67c2ea8263 NonlinearEquality factor is now working for generic configs. Currently, the feasible point must be specified in the form of a full config with the point in it, but this avoid needing to increase the requirements on the configs. 2009-11-13 02:06:52 +00:00
Chris Beall 6252ff2497 added testVSLAMGraph unit test. will fail until we can add a constraint to either one of the two cameras. 2009-11-12 18:55:03 +00:00
Alex Cunningham c7b86cec97 Renamed ConditionalGaussian -> GaussianConditional 2009-11-12 16:41:18 +00:00

Chris Beall 710d396d0b cleaned up a few includes to make VSLAMGraph work properly after the move into gtsam. 2009-11-10 22:49:22 +00:00
Chris Beall 08c9718b12 Moving VSLAMConfig into gtsam. VSLAMFactor lived there already, but was using VectorConfig directly... now using VSLAMConfig. 2009-11-10 20:19:00 +00:00
Manohar Paluri 0d928035e0 added empty constructors for serialization, also made sure SymbolicConditional.h was installed 2009-11-10 14:55:07 +00:00
Alex Cunningham 2c37c94b5d Replaced the householder transform with the weighted system
Removed constrained components from makefile, they will disappear shortly
2009-11-09 21:34:20 +00:00
Frank Dellaert a8d267c4ca Small change necessitating lots of edits: Conditionals now include key of random variable
This simplifies Bayes nets quite a bit. Also created a Conditional base class, derived classes ConditionalGaussian and SymbolicConditional
Finally, some changes were needed because I moved some headers to .cpp
2009-11-02 03:50:30 +00:00
Frank Dellaert 943b692a6b BIG CHANGE: I got rid of the BayesChain/ChordalBayesNet classes and we now simply have a BayesNet class. It will just happen to be chordal when it is the result of an elimination. This will simplify a lot of things.
The main renaming that happened is

BayesChain -> BayesNet
ChordalBayesNet -> GaussianBayesNet == BayesNet<ConditionalGaussian>
SymbolicBayesChain -> SymbolicBayesNet == BayesNet<SymbolicConditional>
2009-10-31 19:53:20 +00:00
Frank Dellaert cefeca149b Moved template definitions to BayesTree-inl.h 2009-10-30 13:03:38 +00:00

Explicit template instantiations
2009-10-30 04:54:11 +00:00
Frank Dellaert dd3795ad5a Symbolic eliminate now works, new compilation unit SymbolicFactor 2009-10-30 03:48:32 +00:00
Frank Dellaert a513ae0287 Changed names and moved two LinearFactorGraph functions to FactorGraph
Added SymbolicFactorGraph compiulation unit and unit tests
Added symbolic combine constructor
2009-10-29 05:39:13 +00:00
Frank Dellaert b6cee73571 Significant change: Made FactorGraph templated on Factor only, and moved error and probPrime to derived classes
Moved find_and_remove_factors to base class
Added and tested symbolic factor graph constructor and conversion from any factor graph type
2009-10-29 04:11:23 +00:00

Frank Dellaert 4d9ff77249 moved timing example here from EasySLAM 2009-10-27 13:34:36 +00:00
Alex Cunningham 7d0a30c20f Renamed FGConfig to VectorConfig in gtsam, easylib, EasySLAM, and mast. 2009-10-14 20:39:59 +00:00
Alex Cunningham 3efe95abee Removed ConstrainedChordalBayesNet and associated test. It may return if ConstrainedConditionalGaussians need more involved processing in future versions, but for all versions of LinearConstraint, there is no need for a special Constrained CBN. 2009-10-08 13:43:43 +00:00
Frank Dellaert 989f290c99 '''BIG CHANGE''': avoid converting back and to FGConfigs by templating on configuration type. Details:
* Factors are now templated on the configuration type. Factor Graphs are now templated on the factor type and configuration type.
 * LinearFactor is a factor on an FGConfig.
 * LinearFactorGraph uses LinearFactor and FGConfig.
 * NonLinearFactor is still templated on Config.
 * NonLinearFactorGraph uses NonLinearFactors, but is still templated on Config.
 * Tests and VSLAMFactor have been updated to reflect those changes.
2009-10-06 18:25:04 +00:00
Frank Dellaert 68e20eec2c 2 BIG changes:
(1) FactorGraph and NonlinearOptimizer now no longer have a .cpp file, but a -inl.h file as in [http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml Google's C++ Style Guide]. This means if you expect to instantiate one of the functions in a cpp file, you have to include the -inl.h file.
(1) getOrdering is now in FactorGraph, and the non-linear version does *not* take a config anymore. 
Long version: I made this change because colamd works on the graph structure alone, and should not depend on the type of graph. Instead, because getOrdering happened to implemented in LinearFactorGraph first, the non-linear version converted to a linear factor graph (at the cost of an unnecessary linearization), and then threw all that away to call colamd. To implement this in a key-neutral way (a hidden agenda), i had to modify the keys_ type to a list, so a lot of changes resulted from that.
2009-09-13 04:13:03 +00:00
Frank Dellaert ead3d03866 BIG: replaced optimize in NonlinearFactorGraph with specialized NonlinearOptimizer object. This does away with the artificial ErrorVectorConfig and the like as NonlinearOptimizer is templated and can use "exmap", the exponential map defined for any differentiable manifold. 2009-09-09 04:43:04 +00:00
