摘要: 该文回顾了近几年来摄像机自标定技术的发展,并分类介绍了其中几种主要方法.同 传统标定方法相比,自标定方法不需要使用标定块,仅根据图像间图像点的对应关系就能估计 出摄像机内参数.文中重点介绍了透视模型下的几种重要的自标定方法,包括内参数恒定和内 参数可变两种情形;最后还简要介绍了几种非透视模型下的摄像机自标定方法.

Abstract: We present a review and classification of camera self-calibration techniques developed in recent years. Compared with traditional calibration techniques, self-calibration does not require a calibration object with known 3D geometry, but only needs point correspondences from images to solve for the intrinsic parameters. Our main focus is on dealing with the pinhole camera model with either constant or varying intrinsic parameters. In the end, we also give a brief review of self-calibration techniques under other camera models. -
