Abstract

SLAM algorithm is based on the static assumption of environment. Therefore, the dynamic factors in the environment will have a great impact on the matching points due to violating this assumption, and then directly affect the accuracy of subsequent camera pose estimation. Recently, some related works generally use the combination of semantic constraints and geometric constraints to deal with dynamic objects, but there are some problems, such as poor real-time performance, easy to treat people as rigid bodies, and poor performance in low dynamic scenes. In this paper, a dynamic scene oriented visual SLAM algorithm based on target detection and static probability named DYP-SLAM is proposed. The algorithm combines semantic constraints and geometric constraints to calculate the static probability of objects, keypoints and map points, and takes them as weights to participate in camera pose estimation. The proposed algorithm is evaluated on the public dataset and compared with a variety of advanced algorithms. It has achieved the best results in almost all low dynamics and high dynamic scenarios, and showing quite high real-time.
