Geometric Consistency for Self-Supervised End-to-End Visual Odometry

no code implementations11 Apr 2018 Ganesh Iyer, J. Krishna Murthy, Gunshi Gupta, K. Madhava Krishna, Liam Paull

We show that using a noisy teacher, which could be a standard VO pipeline, and by designing a loss term that enforces geometric consistency of the trajectory, we can train accurate deep models for VO that do not require ground-truth labels.

CalibNet: Geometrically Supervised Extrinsic Calibration using 3D Spatial Transformer Networks

1 code implementation22 Mar 2018 Ganesh Iyer, R. Karnik Ram., J. Krishna Murthy, K. Madhava Krishna

During training, the network only takes as input a LiDAR point cloud, the corresponding monocular image, and the camera calibration matrix K. At train time, we do not impose direct supervision (i. e., we do not directly regress to the calibration parameters, for example).

Constructing Category-Specific Models for Monocular Object-SLAM

no code implementations26 Feb 2018 Parv Parkhiya, Rishabh Khawad, J. Krishna Murthy, Brojeshwar Bhowmick, K. Madhava Krishna

These category models are instance-independent and aid in the design of object landmark observations that can be incorporated into a generic monocular SLAM framework.

Reconstructing Vechicles from a Single Image: Shape Priors for Road Scene Understanding

no code implementations29 Sep 2016 J. Krishna Murthy, G. V. Sai Krishna, Falak Chhaya, K. Madhava Krishna

We then formulate a shape-aware adjustment problem that uses the learnt shape priors to recover the 3D pose and shape of a query object from an image.
