AI Summary

The field of camera trajectory generation suffers from fragmented knowledge and inconsistent evaluation criteria, lacking a systematic survey. Method: This paper establishes the first unified knowledge framework for the domain, clarifying foundational definitions, a comprehensive technical taxonomy—including rule-based, numerical optimization, supervised/reinforcement learning, and neural motion modeling approaches—and a multidimensional evaluation system. It introduces the first holistic method classification scheme and cross-benchmark evaluation guidelines, integrating mainstream datasets and human-in-the-loop assessment protocols. Contribution/Results: The study identifies critical gaps—insufficient adaptability, low computational efficiency, and limited creative expressivity—and proposes future directions toward efficient modeling, dynamic environment adaptation, and semantics-controllable generation. The framework provides a reusable theoretical foundation and practical paradigm for computer graphics, VR, robotic navigation, and intelligent cinematic production.

Abstract

Camera trajectory generation is a cornerstone in computer graphics, robotics, virtual reality, and cinematography, enabling seamless and adaptive camera movements that enhance visual storytelling and immersive experiences. Despite its growing prominence, the field lacks a systematic and unified survey that consolidates essential knowledge and advancements in this domain. This paper addresses this gap by providing the first comprehensive review of the field, covering from foundational definitions to advanced methodologies. We introduce the different approaches to camera representation and present an in-depth review of available camera trajectory generation models, starting with rule-based approaches and progressing through optimization-based techniques, machine learning advancements, and hybrid methods that integrate multiple strategies. Additionally, we gather and analyze the metrics and datasets commonly used for evaluating camera trajectory systems, offering insights into how these tools measure performance, aesthetic quality, and practical applicability. Finally, we highlight existing limitations, critical gaps in current research, and promising opportunities for investment and innovation in the field. This paper not only serves as a foundational resource for researchers entering the field but also paves the way for advancing adaptive, efficient, and creative camera trajectory systems across diverse applications.
