Paper Abstract

In this paper, two main algorithms about monocular visual odometry is introduced based on 3D-2D motion estimation. A 3D-2D motion estimation method needs to maintain a consistent and accurate set of triangulated 3D features and to create 3D-2D feature matches. Therefore, a keyframe selection strategy is proposed to construct the precise 3D point sets. Based on this strategy, an algorithm is designed to get more proper keyframes by restricting the number of feature points and taking translation amount into account. This keyframe selection strategy will discard inferior frames and construct more precise 3D point sets. We also designed a method to filter 3D-2D feature matches in two different ways. This method contributes to estimating camera pose more accurately. The effectiveness and feasibility of the proposed algorithms were verified in both KITTI outdoor dataset and a real indoor environment. The result of experiment showed that our algorithms can recover the motion trajectory of the camera accurately. And it meet the requirements of real-time and accuracy in monocular visual odometry.
