Abstract

When training samples of existing deep learning-based visual odometry(VO) are different from application scenarios, it is difficult to adapt to the new environment. Therefore, this paper proposed an online updated monocular visual mileage calculation method(OUMVO). In the application stage, it optimized the pose estimation network model online by using the real-time image sequence, which improved the generalization ability of the network and the ability to apply to the new environment. At the same time, it utilized self-supervised learning method without the need to mark the ground truth. Moreover, it adopted Transformer to conduct sequential modeling of image streams to make full use of the visual information within the local window to improve the precision of the pose estimation in order to avoid the limitation that the traditional method could only use two adjacent frames to estimate the pose. It could also compensate for the shortcomings of using RNN for sequence modeling which could not be calculated in parallel. In addition, it used the geometric consistency constraint of the image space to solve the scale drift problem of the traditional monocular visual mileage calculation method. Quantitative and qualitative experimental results on the KITTI dataset show that the proposed method is superior to existing state-of-the-art monocular visual odometry methods in terms of pose estimation accuracy and adaptability to new environments.
