WebThere is a crucial step in the front end of SLAM, which is the keyframe selection method. A simple and popular keyframe selection method in many SLAM systems [2,4–6] is to select keyframes after a constant number of interval frames. Researchers choose an optimal number of frames according to different scenarios and equipment. WebKeyframe selection VIO-mono The average parallax of tracked features between current frame and the latest keyframe is beyond a certain threshold. To avoid rotation-only parallax, rotation compensation via IMU integration is used. The number of tracked features goes below a certain threshold. ORB-SLAM (Surval of the fittest strategy)
