A Fast Feature Point Matching Algorithm Based on IMU Sensor
This addresses real-time processing challenges for low-power embedded systems in SLAM, but it is incremental as it builds on existing IMU and feature matching techniques.
They tackled the time-consuming feature point matching problem in SLAM by proposing an algorithm that uses IMU data to predict search areas, reducing traversal needs. Experimental results show a significant reduction in matching time compared to traditional methods.
In simultaneous localization and mapping (SLAM), image feature point matching process consume a lot of time. The capacity of low-power systems such as embedded systems is almost limited. It is difficult to ensure the timely processing of each image information. To reduce time consuming when matching feature points in SLAM, an algorithm of using inertial measurement unit (IMU) to optimize the efficiency of image feature point matching is proposed. When matching two image feature points, the presented algorithm does not need to traverse the whole image for matching feature points, just around the predicted point within a small range traversal search to find matching feature points. After compared with the traditional algorithm, the experimental results show that this method has greatly reduced the consumption of image feature points matching time. All the conclusions will help research how to use the IMU optimize the efficiency of image feature point matching and improve the real-time performance in SLAM.
