Long wave infrared imaging technology and its application in SLAM
Long wave infrared camera has the advantage of all-weather and all-day,and its application in harsh conditions has attracted extensive attention from scholars at both domestic and international level in recent years.This paper summarizes and analyzes the application of long-wave infrared camera in simultaneous localization and mapping(SLAM).This paper analyzes the difficulties of infrared SLAM research by comparing the similarities and differences between the imaging of infrared cameras and visible light cameras,and summarizes the progress of infrared SLAM research at home and abroad from the four aspects of infrared image feature extraction,infrared odometry,multi-sensor fusion infrared odometry and infrared SLAM.Long wave infrared camera has a good application prospect in challenging environment,but it has obvious shortcomings,and the combination of infrared camera and other sensors should be the focus of research in the future.
