Camera calibration is a critical process in photogrammetry and a necessary step to acquire 3D information from a 2D image. In this paper, a flexible approach for CCD camera calibration using 2D direct linear transformation （DLT） and bundle adjustment is proposed. The proposed approach assumes that the camera interior orientation elements are known, and addresses a new closed form solution in planar object space based on homogenous coordinate representation and matrix factorization. Homogeneous coordinate representation offers a direct matrix correspondence between the parameters of the 2D DLT and the collinearity equation. The matrix factorization starts by recovering the elements of the rotation matrix and then solving for the camera position with the collinearity equation. Camera calibration with high precision is addressed by bundle adjustment using the initial values of the camera orientation elements. The results show that the calibration precision of principal point and focal length is about 0.2 and 0.3 pixels respectivelv, which can meet the requirements of close-range photogrammetry with high accuracy.

在当前中国和世界进行抗疫斗争的实践中,恩格斯健康观无疑对审视资本主义造成的健康问题和指导健康中国建设具有重要意义。恩格斯健康观主要包括三个层面:一是以工人阶级生存状况为核心的主体向度;二是以批判资本主义制度为核心的客体向度;三是以社会主义运动为核心的对资本主义的超越向度。资本主义社会制度必然造成人的体力智力低下从而导致"所有的人退化"的结果,无法真正解决健康问题。因此,需要在批判资本主义的过程中使工人阶级走向"政治健康",工人阶级政党的"健康"发展是超越资本主义社会的关键,社会主义社会必然是真正健康的社会。
