In the new PinholePose philosophy, this is entirely the responsibility of the CAMERA. Just like PinholePose, we can have a camera class that has a shared extra transform: it is part of the calibration. PinholePose itself is not able to do this, as the calibration is assumed 2D only, but it's easy to create a class and have the correct derivatives in place. --- gtsam/slam/SmartFactorBase.h | 42 +---- gtsam/slam/SmartProjectionCameraFactor.h | 10 +- gtsam/slam/SmartProjectionFactor.h | 27 ++-- gtsam/slam/SmartProjectionPoseFactor.h | 16 +- .../tests/testSmartProjectionCameraFactor.cpp | 13 -- .../tests/testSmartProjectionPoseFactor.cpp | 150 ++---------------- .../slam/SmartStereoProjectionFactor.h | 15 +- .../slam/SmartStereoProjectionPoseFactor.h | 11 +- .../testSmartStereoProjectionPoseFactor.cpp | 35 ++-- 9 files changed, 68 insertions(+), 251 deletions(-) diff --git a/gtsam/slam/SmartFactorBase.h b/gtsam/slam/SmartFactorBase.h index 10de39049..56c214264 100644 --- a/gtsam/slam/SmartFactorBase.h +++ b/gtsam/slam/SmartFactorBase.h @@ -76,10 +76,6 @@ protected: typedef Eigen::Matrix VectorD;

Values expect to contain PinholePoses not Pose3s now. The current state of affairs was simply a bug: one pose could be optimized for several different calibrations. It relied on the user to make sure all measurements for a specific pose to optimize were all given the same shared calibration, which was then stored *millions of times* in the pose factors. Instead, there is now *one* shared calibration per PinholePose unknown. --- .cproject | 22 +- examples/SFMExample_SmartFactor.cpp | 15 +- examples/SFMExample_SmartFactorPCG.cpp | 15 +- gtsam/slam/SmartFactorBase.h | 20 +- gtsam/slam/SmartProjectionCameraFactor.h | 20 +- gtsam/slam/SmartProjectionFactor.h | 3 - gtsam/slam/SmartProjectionPoseFactor.h | 70 +---- .../tests/testSmartProjectionPoseFactor.cpp | 263 +++++++++--------- .../examples/SmartProjectionFactorExample.cpp | 30 +- .../slam/SmartStereoProjectionPoseFactor.h | 1 + 10 files changed, 195 insertions(+), 264 deletions(-) diff --git a/.cproject b/.cproject index 5d3733e28..e190d8f65 100644 --- a/.cproject +++ b/.cproject @@ -811,18 +811,10 @@ false true - + make - -j5 - SmartProjectionFactorExample_kitti_nonbatch.run - true - true - true - - - make - -j5 - SmartProjectionFactorExample_kitti.run + -j4 + SmartStereoProjectionFactorExample.run true true true @@ -835,6 +827,14 @@ true true + + make + -j4 + SmartProjectionFactorExample.run + true + true + true + make -j2 diff --git a/examples/SFMExample_SmartFactor.cpp b/examples/SFMExample_SmartFactor.cpp index fce046a59..cd6024e6c 100644 --- a/examples/SFMExample_SmartFactor.cpp +++ b/examples/SFMExample_SmartFactor.cpp @@ -34,6 +34,9 @@ using namespace gtsam; // Make the typename short so it looks much cleaner typedef SmartProjectionPoseFactor SmartFactor; +// create a typedef to the camera type +typedef PinholePose Camera; + /* ************************************************************************* */ int main(int argc, char* argv[]) { @@ -60,7 +63,7 @@ int main(int argc, char* argv[]) { for (size_t i = 0; i < poses.size(); ++i) { // generate the 2D measurement - SimpleCamera camera(poses[i], *K); + Camera camera(poses[i], K); Point2 measurement = camera.project(points[j]); // call add() function to add measurement into a single factor, here we need to add: @@ -68,7 +71,7 @@ int main(int argc, char* argv[]) { // 2. the corresponding camera's key // 3. camera noise model // 4. camera calibration - smartfactor->add(measurement, i, measurementNoise, K); + smartfactor->add(measurement, i, measurementNoise); } // insert the smart factor in the graph @@ -77,15 +80,15 @@ int main(int argc, char* argv[]) { // Add a prior on pose x0.

A corresponding change in the error calculation makes that Jacobian and Hessian factors now agree on error. I think this was a bug, because it affected the error, but (I think) it only pertained to "empty" JacobianFactors which have no bearing on optimization/elimination. --- gtsam/linear/JacobianFactor.cpp | 12 +-- gtsam/linear/tests/testHessianFactor.cpp | 111 +++++++++++----------- gtsam/linear/tests/testJacobianFactor.cpp | 6 +- 3 files changed, 65 insertions(+), 64 deletions(-) diff --git a/gtsam/linear/JacobianFactor.cpp b/gtsam/linear/JacobianFactor.cpp index b38aa89e7..61986e71d 100644 --- a/gtsam/linear/JacobianFactor.cpp +++ b/gtsam/linear/JacobianFactor.cpp @@ -432,8 +432,6 @@ Vector JacobianFactor::error_vector(const VectorValues& c) const { /* ************************************************************************* */ double JacobianFactor::error(const VectorValues& c) const { - if (empty()) - return 0;
