Abstract
En 中文
Estimating frame-;
-frame (F2F) visual odometry with monocular images has significant problems of propagated accumulated drift. We propose a learning-based approach for F2F monocular visual odometry estimation with novel and simple methods that consider the coherence of camera trajec;
ries without any post-processing. The proposed network consists of two stages: initial estimation and error relaxation. In the first stage, the network learns disparity images;
extract features and predicts relative camera pose between adjacent two frames through the attention, rotation, and translation networks. Then, loss functions are proposed in the error relaxation stage;
reduce the local drift, increasing consistency under dynamic driving scenes. Moreover, our skip-ordering scheme shows the effectiveness of dealing with sequential data. Experiments with the KITTI benchmark dataset show that our proposed network outperforms other approaches with higher and more stable performance.
