Core Viewpoint - The article discusses the evolving landscape of 4D annotation in autonomous driving, emphasizing the shift from traditional SLAM techniques to more advanced methods for static element reconstruction and automatic labeling [1][4]. Group 1: Purpose and Applications of Reconstruction - The primary purposes of reconstruction are to create 3D maps from lidar or multiple cameras and to output vector lane lines and categories [5][6]. - The application of 4D annotation in static elements remains broad, with a focus on lane markings and static obstacles, which require 2D spatial annotations at each timestamp [1][6]. Group 2: Challenges in Automatic Annotation - The challenges in 4D automatic annotation include high temporal consistency requirements, complex multi-modal data fusion, difficulties in generalizing dynamic scenes, conflicts between annotation efficiency and cost, and high demands for scene generalization in production [8][9]. - These challenges hinder the iterative efficiency of data loops in autonomous driving, impacting the system's generalization capabilities and safety [8]. Group 3: Course Structure and Content - The course on 4D automatic annotation covers a comprehensive curriculum, including dynamic obstacle detection, SLAM reconstruction principles, static element annotation based on reconstruction graphs, and the end-to-end truth generation process [9][10][17]. - Each chapter includes practical exercises to enhance understanding and application of the algorithms discussed [9][10]. Group 4: Instructor and Target Audience - The course is led by an industry expert with extensive experience in multi-modal 3D perception and data loop algorithms, having participated in multiple production delivery projects [21]. - The target audience includes researchers, students, and professionals looking to transition into the data loop field, requiring a foundational understanding of deep learning and autonomous driving perception algorithms [24][25].
