This paper presents a novel method for calibrating line-scan cameras using a calibration pattern comprising two parallel planes with lines that can be described using known equations. Using pattern geometry and a line that is captured by a line-scan camera, we calculate the 3-D coordinates of ...

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...
between the image position in theory and in practice, and they do not change with object position. Two wide-angle line-scan cameras that are used in a 2D-coordinate measurement system are calibrated by this method; the application results illustrate the effectiveness and convenience of this ...
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 ...
A new and improved line scan camera achieves the proper framing of the image field of view by using a first test card to calibrate the true bottom and leading edge portions of the test card which simulate the true bottom and leading portions of an article being scanned or photographed. Still...
