Detailed Description

template<class... ValueTypes>
class gtsam::NoiseModelFactorN< ValueTypes >

A convenient base class for creating your own NoiseModelFactor with n variables. To derive from this class, implement evaluateError().

For example, a 2-way factor that computes the difference in x-translation between a Pose3 and Point3 could be implemented like so:

class MyFactor : public NoiseModelFactorN<Pose3, Point3> {
 public:
  using Base = NoiseModelFactorN<Pose3, Point3>;
 
  MyFactor(Key pose_key, Key point_key, const SharedNoiseModel& noiseModel)
      : Base(noiseModel, pose_key, point_key) {}
 
  Vector evaluateError(
      const Pose3& T, const Point3& p,
      OptionalMatrixType H_T = OptionalNone,
      OptionalMatrixType H_p = OptionalNone) const override {
    Matrix36 t_H_T;  // partial derivative of translation w.r.t. pose T
 
    // Only compute t_H_T if needed:
    Point3 t = T.translation(H_T ? &t_H_T : 0);
    double a = t(0); // a_H_t = [1, 0, 0]
    double b = p(0); // b_H_p = [1, 0, 0]
    double error = a - b; // H_a = 1, H_b = -1
 
    // H_T = H_a * a_H_t * t_H_T = the first row of t_H_T
    if (H_T) *H_T = (Matrix(1, 6) << t_H_T.row(0)).finished();
    // H_p = H_b * b_H_p = -1 * [1, 0, 0]
    if (H_p) *H_p = (Matrix(1, 3) << -1., 0., 0.).finished();
 
    return Vector1(error);
  }
};
 
// Unit Test
TEST(NonlinearFactor, MyFactor) {
  MyFactor f(X(1), X(2), noiseModel::Unit::Create(1));
  EXPECT_DOUBLES_EQUAL(-8., f.evaluateError(Pose3(), Point3(8., 7., 6.))(0),
                       1e-9);
  Values values;
  values.insert(X(1), Pose3(Rot3::RzRyRx(0.1, 0.2, 0.3), Point3(1, 2, 3)));
  values.insert(X(2), Point3(1, 2, 3));
  EXPECT_CORRECT_FACTOR_JACOBIANS(f, values, 1e-5, 1e-5);
}

These factors are templated on a values structure type. The values structures are typically more general than just vectors, e.g., Rot3 or Pose3, which are objects in non-linear manifolds (Lie groups).

◆ ValueType

template<class... ValueTypes>

template<int I, typename = IndexIsValid<I>>

using gtsam::NoiseModelFactorN< ValueTypes >::ValueType = typename std::tuple_element<I - 1, std::tuple<ValueTypes...> >::type

The type of the I'th template param can be obtained as ValueType. I is 1-indexed for backwards compatibility/consistency! So for example,

using Factor = NoiseModelFactorN<Pose3, Point3>;

Factor::ValueType<1> // Pose3

Factor::ValueType<2> // Point3

// Factor::ValueType<0> // ERROR! Will not compile.

// Factor::ValueType<3> // ERROR! Will not compile.

You can also use the shortcuts X1, ..., X6 which are the same as ValueType<1>, ..., ValueType<6> respectively (see detail::NoiseModelFactorAliases).

Note that, if your class is templated AND you want to use ValueType<1> inside your class, due to dependent types you need the template keyword: typename MyFactor<T>::template ValueType<1>.

◆ evaluateError() [1/5]

template<class... ValueTypes>

Vector gtsam::NoiseModelFactorN< ValueTypes >::evaluateError ( const ValueTypes &... x ) const

inline

No-Jacobians requested function overload. This specializes the version below to avoid recursive calls since this is commonly used.

e.g. const Vector error = factor.evaluateError(pose, point);

Definition at line 663 of file NonlinearFactor.h.

◆ evaluateError() [2/5]

template<class... ValueTypes>

Vector gtsam::NoiseModelFactorN< ValueTypes >::evaluateError	(	const ValueTypes &...	x,
		MatrixTypeT< ValueTypes > &...	H
	)		const

inline

If all the optional arguments are matrices then redirect the call to the one which takes pointers. To get access to this version of the function from derived classes one will need to use the "using" keyword and specify that like this: public: using NoiseModelFactorN<list the value types here>::evaluateError;

Definition at line 649 of file NonlinearFactor.h.

◆ evaluateError() [3/5]

template<class... ValueTypes>

template<typename... OptionalJacArgs, typename = IndexIsValid<sizeof...(OptionalJacArgs) + 1>>

AreAllMatrixRefs<Vector, OptionalJacArgs...> gtsam::NoiseModelFactorN< ValueTypes >::evaluateError	(	const ValueTypes &...	x,
		OptionalJacArgs &&...	H
	)		const

inline

Some (but not all) optional Jacobians are omitted (function overload) and the jacobians are l-value references to matrices. e.g. const Vector error = factor.evaluateError(pose, point, Hpose);

Definition at line 672 of file NonlinearFactor.h.

◆ evaluateError() [4/5]

		OptionalJacArgs &&...	H
	)		const

inline

Some (but not all) optional Jacobians are omitted (function overload) and the jacobians are pointers to matrices. e.g. const Vector error = factor.evaluateError(pose, point, &Hpose);

Definition at line 682 of file NonlinearFactor.h.

◆ evaluateError() [5/5]

template<class... ValueTypes>

virtual Vector gtsam::NoiseModelFactorN< ValueTypes >::evaluateError	(	const ValueTypes &...	x,
		OptionalMatrixTypeT< ValueTypes >...	H
	)		const

pure virtual

Override evaluateError to finish implementing an n-way factor.

Both the x and H arguments are written here as parameter packs, but when overriding this method, you probably want to explicitly write them out. For example, for a 2-way factor with variable types Pose3 and Point3, you should implement:

Vector evaluateError(
    const Pose3& x1, const Point3& x2,
    OptionalMatrixType H1 = OptionalNone,
    OptionalMatrixType H2 = OptionalNone) const override { ... }

If any of the optional Matrix reference arguments are specified, it should compute both the function evaluation and its derivative(s) in the requested variables.

Parameters

	x	The values of the variables to evaluate the error for. Passed in as separate arguments.
[out]	H	The Jacobian with respect to each variable (optional).

◆ key()

template<class... ValueTypes>

template<int I = 1>

Key gtsam::NoiseModelFactorN< ValueTypes >::key ( ) const

inline

Returns a key. Usage: key<I>() returns the I'th key. I is 1-indexed for backwards compatibility/consistency! So for example,

NoiseModelFactorN<Pose3, Point3> factor(noise, key1, key2);
key<1>()  // = key1
key<2>()  // = key2
// key<0>()  // ERROR!  Will not compile
// key<3>()  // ERROR!  Will not compile

Note that, if your class is templated AND you are trying to call key<1> inside your class, due to dependent types you need the template keyword: this->key1().

Definition at line 582 of file NonlinearFactor.h.

template<class... ValueTypes>

Vector gtsam::NoiseModelFactorN< ValueTypes >::unwhitenedError	(	const Values &	x,
		OptionalMatrixVecType	H = `nullptr`
	)		const

inlineoverridevirtual

This implements the unwhitenedError virtual function by calling the n-key specific version of evaluateError, which is pure virtual so must be implemented in the derived class.

Example usage:

gtsam::Values values;
values.insert(...) // populate values
std::vector<Matrix> Hs(2); // this will be an optional output argument
const Vector error = factor.unwhitenedError(values, Hs);

Parameters

[in]	x	A Values object containing the values of all the variables used in this factor
[out]	H	A vector of (dynamic) matrices whose size should be equal to n. The Jacobians w.r.t. each variable will be output in this parameter.

Implements gtsam::NoiseModelFactor.

Definition at line 606 of file NonlinearFactor.h.

◆ unwhitenedError() [2/4]

template<class... ValueTypes>

virtual Vector gtsam::NoiseModelFactor::unwhitenedError

Error function without the NoiseModel, $ z-h(x) $ . Override this method to finish implementing an N-way factor. If the optional arguments is specified, it should compute both the function evaluation and its derivative(s) in H.

◆ unwhitenedError() [3/4]

template<class... ValueTypes>

Vector gtsam::NoiseModelFactor::unwhitenedError

inline

support taking in the actual vector instead of the pointer as well to get access to this version of the function from derived classes one will need to use the "using" keyword and specify that like this: public: using NoiseModelFactor::unwhitenedError;

	)		const
