执行实际摄像机校准 由calibrate_cameras执行的校准取决于参与校准设置的摄像机类型。虽然不同的摄像机设置在获取图像时需要特定的条件,但包括投影和/或远心摄像机的设置的校准过程的基本步骤相似: 构建观察姿态链:在第一步中,操作员calibrate_cameras尝试构建一个有效的观察姿态链,将所有摄像机和校准对象姿态连接到参考...
Description of the internal camera parameters of line scan cameras: CameraType: Type of the camera, as listed above. Focus: Focal length of the lens (only for lenses that perform a perspective projection on the object side of the lens). The initial value is the nominal focal length of ...

MVTec’s software includes operators and development assistants for the calibration of internal and external camera parameters. For the calibration, images acquired from hypercentric, pinhole and telecentric area scan cameras as well as line scan cameras can be used. Calibration capabilities include: Sel...
An imaging model for line scan cameras is proposed.A 3-D calibration pattern with feature lines is purposively designed to calibrate the line scan camera with the properties of cross-ratio.A two-step calibration method is proposed. Nonlinear iteration is applied to refine the linear solution. At...
This paper presents a direct method for the extrinsic calibration of a perspective projection camera and a line-scan LIDAR. We freely move a checkerboard pattern to obtain different plane poses in the camera coordinate system and depth readings in the line-scan LIDAR reference frame. From 3 plane...
