    隨著移動(dòng)機(jī)器人技術(shù)不斷發(fā)展,里程計(jì)技術(shù)已經(jīng)成為移動(dòng)機(jī)器人實(shí)現(xiàn)環(huán)境感知的關(guān)鍵技術(shù),,其發(fā)展水平對(duì)提高機(jī)器人的自主化和智能化具有重要意義,。首先,系統(tǒng)闡述了同步定位與地圖構(gòu)建(Simultaneous localization and mapping, SLAM)中激光SLAM和視覺SLAM的發(fā)展近況,,闡述了經(jīng)典SLAM框架及其數(shù)學(xué)描述,,簡(jiǎn)要介紹了3類常見相機(jī)的相機(jī)模型及其視覺里程計(jì)的數(shù)學(xué)描述。其次,,分別對(duì)傳統(tǒng)視覺里程計(jì)和深度學(xué)習(xí)里程計(jì)的研究進(jìn)展進(jìn)行系統(tǒng)闡述,。對(duì)比分析了近10年來各類里程計(jì)算法的優(yōu)勢(shì)與不足。另外,,對(duì)比分析了7種常用數(shù)據(jù)集的性能,。最后,,從精度、魯棒性,、數(shù)據(jù)集,、多模態(tài)等方面總結(jié)了里程計(jì)技術(shù)面臨的問題,從提高算法實(shí)時(shí)性,、魯棒性等方面展望了視覺里程計(jì)的發(fā)展趨勢(shì)為:更加智能化、小型化新型傳感器的發(fā)展,;與無監(jiān)督學(xué)習(xí)融合,;語義表達(dá)技術(shù)的提高;集群機(jī)器人協(xié)同技術(shù)的發(fā)展,。

    Abstract:

    With the continuous development of mobile robot technology, odometry technology has become a key technology for mobile robots to realize environmental perception, and its development level is of great significance to improving the autonomy and intelligence of robots. Firstly, the current development status of laser simultaneous localization and mapping (SLAM) and visual SLAM in simultaneous localization and mapping was systematically explained. The classic SLAM framework and its mathematical description were expounded, and the camera models of three common types of cameras and their mathematical description of visual odometry were briefly introduced. Secondly, the research progress of traditional visual odometry and deep learning odometry were systematically elaborated. The advantages and disadvantages of various mileage calculation methods in the past ten years were compared and analyzed. In addition, the performance of seven commonly used data sets was comparatively analyzed. Finally, the problems faced by odometry technology were summarized from the aspects of accuracy, robustness, data sets, and multi-modality, and five development trends of visual odometry were prospected from the aspects of improving the real-time performance and robustness of the algorithm. For the development of more intelligent and miniaturized new sensors, the integration with unsupervised learning, the improvement of semantic expression technology and the development of cluster robot collaboration technology were introduced.
