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.
