Abstract: A system and method for visual simultaneous localization and mapping. The method including: extracting a blend of landmarks; associating descriptors and patches of pixels with the extracted landmarks; using the descriptors and patches of pixels, estimating a camera pose by performing feature matching and relative pose estimation; performing joint multi-objective pose optimization over photometric residuals and geometric residuals; updating a local map by performing Bundle Adjustment on the estimated pose; marginalizing extracted landmarks from the local map that are older than a predetermined number of keyframes and adding the descriptors associated with the marginalized landmarks to a global map; where there are loop closure candidates, performing point matching between a keyframe associated with the loop closure candidate and a keyframe most recently added to the global map; and rejecting the keyframe associated with the loop closure candidate if the number of matches is below a predetermined threshold.
