Abstract

In this paper we describe VOPT, a robust algorithm for visual odometry. It tracks features of the environment with known position in space, which can be acquired through monocular or RGBD SLAM mapping algorithms. The main idea of VOPT is to jointly optimize the matching of feature projections on successive frames, the camera’s extrinsic matrix, the photometric correction parameters, and the weight of each feature at the same time, by a multi-scale iterative procedure. VOPT uses GPU acceleration to achieve real-time performance, and includes robust procedures for automatic initialization and recovery, without user intervention. Our tests show that VOPT outperforms the PTAMM algorithm in challenging videos available publicly.
