本文介绍了一种简单的三维（3D）立体的方法，使用一个单一的单元的成像设备组成的电荷耦合器件（CCD）和变焦透镜。与需要一对成像设备的传统立体视觉不同，3D表面成像是通过扫描从两个不同的相机位置获得的两个图像的3D图像重建来实现的。通过以两种不同的方式获得测量目标的两个图像来执行实验：（1）通过在成像装置静止时移动对象，以及（2）通过在对象静止时移动成像装置。传统的立体视觉受到3D图像重建中的视差误差的限制，因为一对成像设备不是理想地相同的，并且在成像系统设置中总是存在对准误差。该方法显著减小了三维图像重建中的视差误差，使成像系统的标定过程变得简单方便。所提出的成像系统在相机像素中显示出0.26的视差误差。
This paper introduces a simple three-dimensional (3D) stereoscopic method using a single unit of an imaging device consisting of a charge-coupled device (CCD) and a zoom lens. Unlike conventional stereoscopy, which requires a pair of imaging devices, 3D surface imaging is achieved by 3D image reconstruction of two images obtained from two different camera positions by scanning. The experiments were performed by obtaining two images of the measurement target in two different ways: (1) by moving the object while the imaging device is stationary, and (2) by moving the imaging device while the object is stationary. Conventional stereoscopy is limited by disparity errors in 3D image reconstruction because a pair of imaging devices is not ideally identical and alignment errors are always present in the imaging system setup. The proposed method significantly reduced the disparity error in 3D image reconstruction, and the calibration process of the imaging system became simple and convenient. The proposed imaging system showed a disparity error of 0.26 in the camera pixel.
